✨ Introduction

OpenStock is a modern stock market app powered by Next.js (App Router), shadcn/ui and Tailwind CSS, Better Auth for authentication, MongoDB for persistence, Finnhub for market data, and TradingView widgets for charts and market views.

🌍 Open Dev Society Manifesto

We live in a world where knowledge is hidden behind paywalls. Where tools are locked in subscriptions. Where information is twisted by bias. Where newcomers are told they’re not “good enough” to build.

We believe there’s a better way.

• Our Belief: Technology should belong to everyone. Knowledge should be open, free, and accessible. Communities should welcome newcomers with trust, not gatekeeping.
• Our Mission: Build free, open-source projects that make a real difference:
  • Tools that professionals and students can use without barriers.
  • Knowledge platforms where learning is free, forever.
  • Communities where every beginner is guided, not judged.
  • Resources that run on trust, not profit.
• Our Promise: We will never lock knowledge. We will never charge for access. We will never trade trust for money. We run on transparency, donations, and the strength of our community.
• Our Call: If you’ve ever felt you didn’t belong, struggled to find free resources, or wanted to build something meaningful — you belong here.

Because the future belongs to those who build it openly.

Prerequisites

• Node.js 20+ and pnpm or npm

• Finnhub API key (free tier supported; real-time may require paid)
• Optional: Gmail account for email (or update Nodemailer transport) if you want welcome and news summary emails
• Optional: Google Gemini API key (for AI-generated welcome intros)

Clone and install

git clone https://github.com/Open-Dev-Society/OpenStock.git
cd OpenStock

# choose one:
pnpm install
# or
npm install

Configure environment

• Create a .env file (see Environment Variables).
• Verify DB connectivity:

pnpm test:db
# or
npm run test:db

Run development

# Next.js dev (Turbopack)
pnpm dev
# or
npm run dev

Run Inngest locally (workflows, cron, AI)

npx inngest-cli@latest dev

Build & start (production)

pnpm build && pnpm start
# or
npm run build && npm start

Open http://localhost:3000 to view the app.

🐳 Docker Setup

You can run OpenStock and MongoDB easily with Docker Compose.

1. Ensure Docker and Docker Compose are installed.

2. docker-compose.yml includes two services:

• openstock (this app)
• mongodb (MongoDB database with a persistent volume)

3. Create your .env (see examples below). For the Docker setup, use a local connection string like:

MONGODB_URI=mongodb://root:example@mongodb:27017/openstock?authSource=admin

4. Start the stack:

# from the repository root
docker compose up -d mongodb && docker compose up -d --build

5. Access the app:

• App: http://localhost:3000
• MongoDB is available inside the Docker network at host mongodb:27017

Notes

• The app service depends_on the mongodb service.
• Credentials are defined in Compose for the MongoDB root user; authSource=admin is required on the connection string for root.
• Data persists across restarts via the docker volume.
• NODEMAILER_EMAIL and NODEMAILER_PASSWORD are optional for local Docker runs. If they are omitted, the app still starts but email features stay disabled.

Optional: Example MongoDB service definition used in this project:

services:
  mongodb:
    image: mongo:7
    container_name: mongodb
    restart: unless-stopped
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    ports:
      - "27017:27017"
    volumes:
      - mongo-data:/data/db
    healthcheck:
      test: ["CMD", "mongosh", "--eval", "db.adminCommand('ping')"]
      interval: 10s
      timeout: 5s
      retries: 5

volumes:
  mongo-data:

Notes

• Keep private keys server-side whenever possible.
• If using NEXT_PUBLIC_ variables, remember they are exposed to the browser.
• In production, prefer a dedicated SMTP provider over a personal Gmail.
• If the Nodemailer credentials are omitted, the app still runs but welcome and news summary emails are disabled.
• Do not hardcode secrets in the Dockerfile; use .env and Compose.

❤️ Sponsor OpenStock

OpenStock is free, open source and used by 13,000+ registered people. Keeping it that way costs money every month: hosting, the database, market data keys, AI and email, and the hours that go into reviewing pull requests and shipping fixes.

How OpenStock is funded

• OpenStock Cloud will pay for hosting. Cloud ($5 a month, coming soon) adds live quotes and email price alerts. Its subscribers will cover the servers, database and market data the hosted app needs, so the free site stays online without depending on donations.
• Sponsors keep the community moving. Sponsorships pay for the time behind OpenStock: reviewing community pull requests, fixing bugs and shipping features at the pace 13,000+ people expect, with the core free for everyone. Self-hosting stays free, with every feature.

Pick a tier. Each link opens GitHub Sponsors with the amount already selected. Cancel any time.

Tier	Monthly	What you get
Backer	$5	Your name in this README
Supporter	$25	Name and avatar on the sponsor wall and the sponsor page
Company	$100	Your logo in the footer of every public page, in this README and on the sponsor page
Partner	$500	One of three sponsor slots in the app sidebar, seen by 13,000+ registered users, plus your logo on the landing page

Rather give once? Make a one-time gift. Want an invoice or a custom partnership? Talk with us. Everything, including where the money goes, is on the sponsor page.

Sponsorships are paid through GitHub Sponsors to @ravixalgorithm (Ravi Pratap Singh, founder of Open Dev Society).
