OpenStock

OpenStock is an open-source alternative to expensive market platforms. Track real-time prices, set personalized alerts, and explore detailed company insights — built openly, for everyone, forever free.

Note: OpenStock is community-built and not a brokerage. Market data may be delayed based on provider rules and your configuration. Nothing here is financial advice.

✨ 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.

🤸 Quick Start

Prerequisites

Node.js 20+ and pnpm or npm
MongoDB connection string (MongoDB Atlas or local via Docker Compose)
Finnhub API key (free tier supported; real-time may require paid)
Gmail account for email (or update Nodemailer transport)
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:

1
2
3

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)

`1`	`npx inngest-cli@latest dev`

Build & start (production)

1
2
3

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.

Ensure Docker and Docker Compose are installed.
docker-compose.yml includes two services:

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

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

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

Start the stack:

1
2

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

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.

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:

🔐 Environment Variables

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.
Do not hardcode secrets in the Dockerfile; use .env and Compose.
