Agentless Windows workflow orchestration, a modern, open replacement for Microsoft System Center Orchestrator.
Multi-step automation is designed, scheduled, debugged and observed in the browser. PowerShell, file, registry and service operations, REST calls, SQL and further activities are executed across a Windows estate over WinRM, without agents on the targets.
🌐 Website ·
Open the live demo to try the actual web UI with sample data. It runs entirely in the browser, requires no installation and sends no data anywhere. Each visitor has a private copy, which resets on reload. Workflows can be built, published and run, while the canvas updates live.
It is the product's own frontend on an in-memory backend, so anything that genuinely needs a server (PowerShell on a host, a WinRM test, mail, a restore) reports that limitation instead of pretending.
The video shows SCOrch import, the Workflow Designer, execution history, Live Ops, logs as well as AI chat in operation. English captions, no audio.

NodePilot is a drop-in modern alternative for organizations that remain on legacy SCOrch. The agentless model and the target audience are the same (sysadmins automating Windows estates) but the product is built on a current stack with a user experience that does not resemble a 2010 MMC snap-in.
Highlights
- SCOrch runbooks import directly: native
.ois_exportXML, with activities, links, conditions, global variables as well as Published Data references translated into NodePilot's data bus. How it works. - Visual designer: a drag-and-drop canvas with 27 activity types, 6 triggers, typed nodes, a visual condition builder and a seven-cluster toolbar that places every editing affordance one click away.
- True parallel engine: an event-driven scheduling loop with real fan-out / fan-in, three junction modes (
waitAll/waitAny/waitNofM), per-step DI scope and skip propagation. - Step debugger: breakpoints, conditional breakpoints, step-over, a live variable inspector with runtime overrides, and time-scrubbing replay in the Gantt timeline.
- Real-time UI: SignalR streams step status, output and variables to every connected client while the workflow runs.
- Agentless remote execution: WinRM and the PowerShell SDK. Localhost runs in-process without WinRM.
- AI-assisted authoring: PowerShell scripts and entire workflows are generated from natural language. Generation works against OpenAI or local Ollama / LM Studio / vLLM for zero-egress setups.
- Global AI chat: a read-only assistant available from the bottom-right chat button and from its own page (
/ai-chat), sharing conversations, drafts and ongoing answers across navigation. Answers use admin-switchable knowledge sources: documentation, operational data scoped by folder permissions, source code, and read-only SQL against the database. Every source is opt-in. The chat never executes or publishes anything. - Operations CLI (
np): a full-featured command-line client covering login, run, watch, audit, lock/publish as well as import/export, published as a self-contained folder forPATH. - Drivable by AI agents: an opt-in MCP server (
nodepilot-mcp) exposes NodePilot to Claude Code, Claude Desktop and any other MCP client — 102 tools over 10 groups, HTTP-only against the same REST API, with destructive operations gated. - Batteries-included observability: an opt-in OpenTelemetry and Prometheus exporter, plus a hardened, loopback-bound Grafana stack with 10 pre-provisioned dashboards (Mission Control, Workflows, Activities, WinRM, Triggers, API, Runtime, Security, AI, Database). Startup requires a unique
NODEPILOT_GRAFANA_ADMIN_PASSWORD. Compose fails closed while the password is missing, rather than coming up on a default credential. - SCOrch-style edit lock: an atomic per-user check-out and publish flow,
423 Lockedenforced by every mutating endpoint, force-unlock for admins with audit trail. - Workflow versioning: every edit is snapshotted, rollback takes one click, and any two versions can be compared visually.
- JWT and RBAC: Admin / Operator / Viewer roles, BCrypt passwords, account lockout, DPAPI-encrypted credentials, output redaction, SSRF guards, per-IP rate limits, and an
audit-eventalert source that pages on failed logins, lockouts, break-glass sign-ins and privilege changes without a SIEM. - AD SSO Preview (opt-in): hardened LDAP/Kerberos, OIDC and SCIM, server-side sessions as well as directory-backed RBAC complement Active/Passive HA, secret providers and ECS-JSON SIEM logging. Production status remains Preview until the real AD/Kerberos/LDAPS field gate passes. See docs/enterprise-features.md.
- Production-grade deployment: a turnkey PowerShell installer for a Windows Service under a gMSA, direct Kestrel HTTPS, install/data-dir split, and in-place upgrades with auto-rollback.
SCOrch is not going anywhere. System Center 2025 Orchestrator shipped in November 2024 with mainstream support to January 2030 and extended support to January 2035. An existing installation is therefore not on a deadline, and this section is not a migration pitch.
What has not moved is authoring. The web console added in 2022 runs and monitors runbooks. It cannot build them. Writing one still requires the desktop Runbook Designer on a machine with the client installed, and once it is written there is no version history, no diff between two states and no rollback. NodePilot is built for that gap: the same agentless model, the same job, the same people, with the editor, the debugger and the version history in a browser.
Existing runbooks come across. NodePilot reads SCOrch's native .ois_export XML directly (exports from 2012, 2016 and 2019 all parse) and turns runbooks into workflows:
- Activities are mapped, not dropped. Roughly forty SCOrch type names translate directly: scripts and programs, the file, folder, archive and text-file activities, Query XML, Query Database, Query WMI, Invoke Web Services, Send Email, Start/Stop Service, Restart System, Generate Random Text, the Monitor activities that have a NodePilot trigger, as well as the Runbook Control set (Initialize Data, Return Data, Junction, and Invoke Runbook, which SCOrch writes as
Trigger Policy) including the arguments passed to a child runbook. - Published Data becomes the data bus. SCOrch's
\`d.T.~Vb/{GUID}\`d.T.~Vb/references are rewritten into NodePilot's{{globals.Name}}and{{step.param.field}}syntax, resolving through a readable name derived from each activity rather than a bare GUID. Where the two products name the same value differently the field is translated as well. Should SCOrch have published something for which NodePilot has no equivalent, the reference is reported instead of quietly pointing at the nearest-looking name. This is usually the part that makes a migration expensive. - Branches keep branching. Compare Values becomes a
decision, and the links that read its result are re-pointed at it. A comparison whose outcome nothing could read would leave every branch behind it dead. - Links, conditions and global variables come across, including on-success and on-failure links, the
TRIGGERSfilter logic, and whether a link matched all or any of its filters. - Every runbook is runnable on arrival. NodePilot starts a workflow from a trigger node, and a SCOrch runbook invoked by another needs no trigger of its own. One is therefore added and wired to the entry activities.
- Nothing disappears silently. An activity the importer cannot map becomes a disabled placeholder carrying the original type name and its full property list. A mapping that cannot fill a required setting degrades to one as well, rather than leaving a node that looks configured and does nothing. The import report names every lossy translation: a reference to a field the NodePilot activity does not publish, a reference across parallel branches (SCOrch's data bus is run-scoped, NodePilot's is ancestor-scoped), a remote step with no target machine, a dropped run-as account, an approximated schedule, and any link that ended up unconditional.
- The folder tree comes across. A SCOrch export carries the structure its console showed, for runbooks and for global variables, and the import rebuilds both below the chosen destination, reusing folders that are already there. Re-filing a few hundred workflows by hand is work a migration should not create.
- The canvas resembles the original runbook. SCOrch positions activities as small icons on a tight grid. NodePilot draws cards several times that size, so the coordinates cannot be copied as they are. The graph is scaled uniformly instead, a similarity transform, so every distance keeps its ratio and the arrangement is the one its author drew, only larger. Links are then made to read as curves rather than the angular loop the designer draws for an edge running backwards: a pair stacked in one column docks top-to-bottom without either node moving, and anything else is nudged apart horizontally. Rows are never touched. Should the arrangement not be reproducible (activities sharing a position, or spaced too tightly for any usable canvas) the import reports this and falls back to a left-to-right layout.
Import runs from the UI, from POST /api/workflows/import-scorch, or from the CLI:
np workflow import-scorch --file .\runbooks.ois_exportThe result is to be treated as a reviewed draft, not as a finished migration. Imported workflows arrive disabled, credentials are never reconstructed because SCOrch encrypts them, and anything the report flags needs a decision. After review, a workflow is activated explicitly through POST /api/workflows/{id}/enable or np workflow enable <id>. Both import APIs return the created ids, and the CLI exposes the same report as machine-readable stdout with -o json. The point is that a migration starts from actual runbooks instead of a blank canvas.

The last row is the honest one. NodePilot provides the source, not a support contract, and is to be judged on that basis.
NodePilot runs in exactly three supported shapes. Pick the row that describes you. Each one is a complete route to a working login, and nothing below mixes them.
| 1 · Desktop app | 2 · Windows service | 3 · From source | |
|---|---|---|---|
| For | one person, one machine | a team, a real server | contributors, evaluation |
| You need | Windows 11 x64, local admin | Windows Server 2022/2025, a TLS certificate, a prepared database | .NET 10 SDK, Node, a local PostgreSQL |
| You get | installer .exe: bundles a local PostgreSQL and the .NET runtime, installs both as services, opens a native window |
setup .exe (or the signed .zip + PowerShell installer), Windows service under a gMSA, Kestrel HTTPS |
dotnet run + Vite dev server on your own machine |
| Database | bundled, loopback-only | you provide it | you provide it |
| Offline | yes, fully | yes | no (package restore) |
| Guide | below · details | below · step-by-step | below |
NodePilot is Windows-only by design, the engine drives PowerShell remoting over WinRM and protects credentials with DPAPI. There is no Linux, container or Kubernetes target.
Every path ends the same way: the first login creates the Admin account, and it requires a one-time setup token. Where you find that token differs per path and is called out below.
A local desktop application for Windows 11 x64: one .exe that bundles the app, a self-contained .NET 10 runtime as well as a local PostgreSQL server, installs everything as background Windows services, and opens a native Electron window on top. It is fully offline, with no runtime prerequisites and no external database.
NodePilot-Desktop-Setup-<version>.exe is downloaded from the latest release and run. The installer requires local admin: it provisions the database cluster, a loopback certificate and both services, then launches the shell and hands the first-run setup token straight to the login screen. No file has to be located manually. Should provisioning fail, the installer reports this and names its log, rather than finishing green with an app that will not start. When something does go wrong, docs/desktop-troubleshooting.md covers the log locations, first-run recovery and a complete removal. The full inventory of every log file (server and desktop, with paths, retention and which one to read when) is at Logs & diagnostics.
The backend runs as an always-on service. This means that scheduled and webhook triggers keep firing while the window is closed. It uses the Deployment:Mode=Desktop posture: Production-hardened, but with a loopback-only Kestrel and a 127.0.0.1 Postgres. The Electron shell is a thin, hardened viewer that pins the loopback certificate by SHA-256 and trusts no system root CA.
Building the installer yourself
The build requires .NET 10 SDK, Node, Inno Setup 6 (ISCC.exe) as well as a PostgreSQL 16 binaries folder, the pgsql directory from the EDB zip distribution. Should either of the last two be missing, the build fails fast. Expect 10–15 minutes.
deploy\desktop\Build-DesktopInstaller.ps1 -PgBinariesPath 'C:\Packages\pgsql' -Version 1.2.0
# -> deploy\desktop\out\NodePilot-Desktop-Setup-1.2.0.exeBuild-DesktopInstaller.ps1 never signs, it has no signing parameter at all. A signed installer is produced through the release build instead:
deploy\Build-Artifact.ps1 -SigningCertificateThumbprint <artifact-signer> `
-IncludeDesktopInstaller -PgBinariesPath 'C:\Packages\pgsql' `
-InstallerSigningCertificateThumbprint <authenticode-signer>Signing belongs in the build rather than afterwards, because signing rewrites the .exe and would invalidate its entry in NodePilot-<version>.SHA256SUMS.txt. Signing does not silence SmartScreen. A downloaded installer warns on first launch either way, since the publisher certificate is self-signed and carries no reputation (see deployment-guide.md). Internals, service identities and the first-run handoff are documented in deploy/desktop/README.md.
The production rollout consists of a signed artifact plus a PowerShell installer that registers NodePilot as a Windows service under a gMSA, terminates HTTPS in Kestrel directly, and splits install and data directories so that in-place upgrades can roll back.
Prerequisites (all enforced by the installer's pre-flight, which fails with a named error):
- Windows Server 2022 or 2025, domain-joined for the gMSA path,
-UseLocalSystemworks without a domain - .NET Runtime and ASP.NET Core Runtime, 10.0.11 or newer in the 10.x line, both x64 — two downloads, and both are needed: the ASP.NET Core package carries only
Microsoft.AspNetCore.Appand nodotnet.exe, so on a machine without .NET it leaves a framework nothing can load. Not the Hosting Bundle, which wires up IIS and restarts W3SVC. NodePilot ships aswin-x64. A 32-bit runtime cannot host it, and the pre-flight reports this rather than passing the row - PostgreSQL 16+ or SQL Server 2022 CU1+ (build ≥ 16.0.4003.1, earlier builds cannot serve the
Encrypt=Strict/ TDS 8.0 connections NodePilot opens, and are rejected) - a TLS certificate in
Cert:\LocalMachine\Mywith its private key - antivirus exclusions agreed with the security team. See docs/av-exclusions.md
There are two ways to run it, and they install the same thing.
With the wizard. NodePilot-Server-Setup-<version>.exe is downloaded from the latest release and run. It carries the signed artifact and both .NET runtimes, checks every prerequisite above before changing anything (showing each as green, amber or red with a copyable fix) and can install the runtime, create the SQL login and database, or issue a lab certificate. One file instead of five, and no manual thumbprint comparison. Unattended: Setup.exe /VERYSILENT /SUPPRESSMSGBOXES /ANSWERFILE=answers.json. Details, answer-file schema and switches are documented in deploy/server/README.md.
With the scripts, which is what the wizard runs and what automation should use. The signed NodePilot-<version>.zip is downloaded together with its .manifest.json and .manifest.json.p7s, verified against NodePilot-<version>.SHA256SUMS.txt, and then installed:
.\deploy\Install-NodePilot.ps1 `
-ArtifactPath 'C:\Packages\NodePilot-1.2.0.zip' `
-TrustedArtifactSignerThumbprint '<publisher thumbprint from the release notes>' `
-CertThumbprint '<your TLS cert thumbprint>' `
-ServiceAccount 'CONTOSO\svc-nodepilot$' `
-PublicHostname 'nodepilot.corp.example.com'The installer refuses unsigned or tampered artifacts. -TrustedArtifactSignerThumbprint is mandatory, and the signature, the signer's identity, its code-signing eligibility as well as its validity are all verified, not just the hash. It does not require the publisher to be trusted on the target machine: pinning the thumbprint is the trust decision, so there is nothing to import before installing. If you build the artifact yourself you also sign it yourself, docs/deployment-guide.md walks through creating the self-signed code-signing certificate.

Verifying what you downloaded, and building it yourself, plus a troubleshooting table for what actually goes wrong: docs/deployment-guide.md. Operator reference, every parameter, update and uninstall: deploy/README.md.
For contributors and for evaluation on a workstation.
Prerequisites
- Windows 10 / 11, or a Windows Server. This path is not picky and only requires Windows
- .NET 10 SDK: download. The exact band is pinned in
global.json - Node.js: the minimum is declared in each
package.jsonenginesfield (react-router 8 sets it),npmwarns below it - PostgreSQL 16+: or SQL Server 2022 CU1+ with
Database:Provider: sqlserver
1. Create the database
Neither shipped connection string carries a password, so this step is not optional.
winget install PostgreSQL.PostgreSQL
$psql = "C:\Program Files\PostgreSQL\16\bin\psql.exe"
& $psql -U postgres -c "CREATE ROLE nodepilot WITH LOGIN PASSWORD 'ChangeMe!';"
& $psql -U postgres -c "CREATE DATABASE nodepilot OWNER nodepilot;"2. Start the backend (port 5000)
The password is passed through the environment rather than into a tracked file, so that it never becomes a commit:
$env:ConnectionStrings__Postgres = "Host=127.0.0.1;Port=5432;Database=nodepilot;Username=nodepilot;Password=ChangeMe!;SSL Mode=Disable"
cd src\NodePilot.Api
dotnet runPostgreSQL is started before the API. Without a reachable database the process exits during the migration bootstrap and reports which server and database it could not reach.
On first start NodePilot writes a one-time setup token to admin-setup.token next to the project, src\NodePilot.Api\admin-setup.token, in the content root rather than the directory the process was started from. Sign-in uses the intended admin username and password. The login screen reveals a Setup token field on the first attempt, and pasting the token creates the Admin account.
3. Start the frontend (port 5173)
cd src\nodepilot-ui
npm install
npm run devhttp://localhost:5173 serves the app, the Vite dev server proxies /api, /healthz and /hubs to port 5000.
4. (optional) Bring up Grafana
cd grafana
Copy-Item .env.example .env # then set NODEPILOT_GRAFANA_ADMIN_PASSWORD - compose refuses to start without it
docker compose up -d
# Grafana -> http://localhost:3000 (user "admin", the password you just set)
# Prometheus -> http://localhost:9090The Prometheus exporter is then enabled on the API. All three variables are required. The third is what lets Prometheus scrape /metrics without credentials:
$env:OpenTelemetry__Enabled = "true"
$env:OpenTelemetry__Exporters__PrometheusScrape = "true"
$env:OpenTelemetry__Exporters__PrometheusScrapeAllowAnonymous = "true"See grafana/README.md for the full walk-through.
The same walkthrough, with more detail per step, lives on the documentation site, in English and German.
Want to see the designer without building anything? The bundled showcase is a nightly fleet health-check that fans out three parallel probes, gathers them at a junction, and routes a decision to an alert or an all-green log:
scripts/readme-showcase-workflow.json
Import runs via the Workflows page → Import, or through POST /api/workflows/import. It exercises every shape that occurs in production: schedule trigger, runScript, log, junction (waitAll), decision, emailNotification, returnData, as well as three phase sticky-notes, laid out to fill the canvas width and run top-to-bottom.
Everything below the surface lives on the documentation site, 44 pages in English and German, with search and deep links. This README deliberately stops at "installed and logged in".
| Start here | Introduction · Installation · Architecture |
| Building workflows | Workflows & activities · Data bus & variables · Edge conditions · Sub-workflows |
| The designer | Overview · Canvas, nodes & edges · Properties, modes & shortcuts |
| Reference | All 27 activities · Triggers · API endpoints · np CLI · MCP server |
| Running it | Windows Server · Desktop app · Antivirus exclusions · Logs & diagnostics · Configuration |
| Security | Security model · Hardening flags · Audit log |
| Enterprise | High availability · Secret providers · AD SSO Preview · Folder RBAC |
The API also documents itself. The OpenAPI spec is served at GET /openapi/v1.json, with Swagger UI at GET /swagger, in Development by default.
A real server rollout follows Windows Server deployment on the documentation site, a lab-validated walkthrough covering service identity, both database providers, certificates and the first admin account. The installer runs NodePilot as a Windows service under a gMSA with direct Kestrel HTTPS, splits install and data directories, and upgrades in place with automatic rollback.
Two companions belong to it. docs/deployment-guide.md covers what happens before installation (verifying the download against its checksums and publisher, and building the artifact in-house) and carries the troubleshooting table. deploy/README.md is the parameter reference, and states what the installer deliberately does not do.
Before a deployment into an environment with endpoint protection, docs/av-exclusions.md is to be handed to whoever owns it. NodePilot runs PowerShell by design, and that trips heuristics.

Six CI jobs gate every pull request and every push to main: backend build and tests with an enforced 85 % line / 70 % branch coverage gate, frontend lint/build/vitest, docs-site lint/tests/build, desktop-shell typecheck and tests, as well as hermetic Playwright E2E. A local nightly task runs the same four suites against the checked-out tree.
Tests are mandatory. Every behaviour change ships with tests in the same change. Which tests you run locally is scoped to what you touched. The full suite is CI's responsibility, not yours. Commands, the scoping rules and the guard-test mapping are documented in CONTRIBUTING.md and CLAUDE.md.
Two conventions are worth knowing beforehand: the WinRM remote layer is always mocked, and backend database tests run on in-memory SQLite, a test backend only, never a supported production provider.
Contributions are welcome. CONTRIBUTING.md has the full setup: prerequisites, how to obtain a local PostgreSQL and a first admin account, the build and test commands, as well as the conventions that CI enforces.
The short version:
- Open an issue first for anything non-trivial, it saves a round of "we already explored that" review comments.
- Tests ship with the change, not after it. CI fails without them.
- No backwards-compat shims. NodePilot is greenfield, replace cleanly rather than keeping the old path alive behind a flag.
- Hand-built workflow JSON requires docs/workflow-styleguide.md first, layout rules, edge-label conventions, and engine gotchas.
A security problem does not belong in a public issue. SECURITY.md has the private reporting path. Everyone taking part is expected to follow the Code of Conduct.
CLAUDE.md is working notes for AI coding agents, not contributor documentation. It is checked in deliberately: NodePilot is built with agentic engineering, so the context an agent needs to work on this codebase belongs in the repository rather than in someone's private setup. What that does not change is the bar every change has to clear, behaviour changes ship with tests, and CI enforces the coverage gate on every pull request. CONTRIBUTING.md is the file written for people.
