🔋 Features

Markets

• A dashboard for seven markets: US, India, Germany, Canada, Australia, Crypto and Forex, with an index pulse, a sector heatmap, market leaders and top stories.
• Search every exchange Finnhub covers with ⌘K, and keep stocks open as browser-style tabs.

Stock pages

• TradingView candles with drawing tools (trend lines, Fibonacci, shapes, text) and fullscreen.
• Pick indicators once (SMA, EMA, Bollinger Bands, VWAP, RSI, MACD, Stochastic, ATR) and they stay on every chart.
• Financials, technicals and the company profile.
• Sentiment from Reddit, X, news and Polymarket (with an Adanos key).

Watchlist and alerts

• A watchlist of up to 50 stocks, saved to your account.
• Price alerts above or below a target, checked every 5 minutes and emailed to you (in realtime mode).
• A weekly, AI-written news digest by email every Monday.

Accounts

• Email and password, plus Google and GitHub sign-in when configured; password reset and a profile page.
• Rate-limited sign-in, sign-up and password reset; resetting your password signs out your other devices.

Community

• A changelog that credits everyone who contributed, a Wall of love, and an update banner in the app.

⏱️ How fresh is the data

Charts always stream live from TradingView. Quotes, watchlist prices and alerts come from Finnhub:

	Quotes	Price alerts	Cost
Community: openstock-ods.vercel.app	Every hour, shared by everyone	No	Free
OpenStock Cloud (coming soon)	Every 15 seconds	By email	$5 a month
Self-hosted	Every hour, or every 15 seconds with NEXT_PUBLIC_OPENSTOCK_DATA_MODE=realtime and your own Finnhub keys	By email, in realtime mode	Free

⚙️ Tech stack

App	Next.js 15 (App Router), React 19, TypeScript, Tailwind CSS v4, shadcn/ui and Radix
Accounts and data	Better Auth, MongoDB with Mongoose
Market data	Finnhub, TradingView widgets, Adanos (sentiment)
Background jobs	Inngest
Email	Nodemailer (Gmail), Kit for the newsletter
AI	Gemini, MiniMax or Siray
Hosting	Vercel; a Docker image on GitHub Container Registry for self-hosting

🤸 Quick start

You need Node.js 22 LTS, a MongoDB database (a free Atlas cluster, or the Docker setup) and a free Finnhub key.

git clone https://github.com/Open-Dev-Society/OpenStock.git
cd OpenStock
npm ci
cp .env.example .env         # fill in MONGODB_URI, BETTER_AUTH_SECRET and FINNHUB_API_KEY
node scripts/check-env.mjs   # checks your .env
npm run test:db              # checks the MongoDB connection
npm run dev                  # http://localhost:3000

Welcome emails, price alerts and the weekly digest run as Inngest jobs. Locally, start Inngest's dev server alongside the app: npx inngest-cli@latest dev.

For production: npm run build && npm start.

🔐 Environment variables

Every variable is listed with comments in .env.example. The ones that matter:

Variable	Needed	What it's for
MONGODB_URI	Yes	Your MongoDB database
BETTER_AUTH_SECRET	Yes	Signs sessions. Generate it with openssl rand -hex 32. Auth refuses to run in production without it
BETTER_AUTH_URL	Yes	The app's public URL, used for auth callbacks and links in emails
FINNHUB_API_KEY	Yes	Market data. Or put several free keys, comma-separated, in FINNHUB_API_KEYS: they're rotated, and each adds 60 requests a minute
NEXT_PUBLIC_OPENSTOCK_DATA_MODE	No	cached (hourly, the default) or realtime (every 15 seconds, with price alerts). Fixed when the app is built: rebuild after changing it
INNGEST_SIGNING_KEY, INNGEST_EVENT_KEY	In production	Background jobs: welcome emails, price alerts and the weekly digest
NODEMAILER_EMAIL, NODEMAILER_PASSWORD	No	Sending email through Gmail, with an app password. Without them, emails are skipped
GEMINI_API_KEY (or MiniMax or Siray)	No	AI-written welcome emails and the news digest
ADANOS_API_KEY	No	The sentiment card on stock pages
KIT_API_KEY, KIT_API_SECRET, KIT_WELCOME_FORM_ID	No	The weekly digest newsletter in Kit
GOOGLE_CLIENT_ID / _SECRET, GITHUB_CLIENT_ID / _SECRET	No	Social sign-in. Callbacks: <BETTER_AUTH_URL>/api/auth/callback/google and /github

NEXT_PUBLIC_FINNHUB_API_KEY still works as a name for the Finnhub key. No key is ever sent to the browser.

🐳 Self-hosting

Docker Compose

Runs OpenStock and MongoDB together. MongoDB is only reachable inside the Docker network; it isn't published on your machine.

1. Fill in .env (see above). For the bundled database, choose a password and use it in both places. Letters and digits are simplest; @ : / ? # must be percent-encoded in the URI.

   MONGO_ROOT_PASSWORD=change-me
   MONGODB_URI=mongodb://root:change-me@mongodb:27017/openstock?authSource=admin
   

2. Start it: docker compose up -d --build
3. Open http://localhost:3000

The image build needs no secrets: every variable is read when the container starts, except NEXT_PUBLIC_OPENSTOCK_DATA_MODE, which Compose passes to the build from .env. Data lives in the mongo-data volume, and the MongoDB password is only applied when that volume is first created.

Prebuilt image

Every push to main publishes ghcr.io/open-dev-society/openstock for amd64 and arm64, tagged latest, sha-<commit>, and a version for each release (for example 2026.10.18). To use it, replace build: under openstock in docker-compose.yml with:

    image: ghcr.io/open-dev-society/openstock:latest

then run docker compose pull && docker compose up -d. The prebuilt image runs in cached mode; build it yourself for realtime.

One-click deploys

Railway

OpenStock ships a railway.json that builds the Dockerfile, checks health on /sign-in and restarts on failure. The template above sets everything up; to do it by hand:

1. Create a project and add a MongoDB database (+ New → Database → MongoDB).
2. Add a service from this repository (+ New → GitHub Repo).
3. In the service's Variables, set:

   MONGODB_URI=${{MongoDB.MONGO_URL}}
   BETTER_AUTH_SECRET=${{secret(32)}}
   BETTER_AUTH_URL=https://${{RAILWAY_PUBLIC_DOMAIN}}
   FINNHUB_API_KEY=your_finnhub_key
   GEMINI_API_KEY=your_gemini_api_key
   INNGEST_SIGNING_KEY=your_inngest_signing_key
   INNGEST_EVENT_KEY=your_inngest_event_key
   [email protected]
   NODEMAILER_PASSWORD=your_gmail_app_password
   

4. Under Settings → Networking, generate a public domain and redeploy.

For background jobs, add your Railway domain as an app in the Inngest dashboard, pointing to https://<your-domain>/api/inngest. To turn on realtime mode, also set NEXT_PUBLIC_OPENSTOCK_DATA_MODE=realtime; Railway passes it to the build.

Vercel

Import the repository, set the variables above for Production, and connect Inngest (its Vercel integration sets both keys). vercel.json pins functions to Mumbai (bom1), next to the hosted database; change it to the region nearest yours.

📡 How it works

• Finnhub: search, quotes, company profiles and news. Responses are cached and shared (for an hour, or 15 seconds in realtime mode), with timeouts and a key pool, so a slow upstream never hangs a page.

• TradingView: the chart, heatmap, financials, technicals and profile widgets.

• Adanos (optional): the sentiment card.

• Better Auth with MongoDB: accounts and sessions. Pages and server actions check the session on the server; the middleware only redirects signed-out visitors.

• Inngest runs the background jobs:

  Job	When
  AI-personalised welcome email	On sign-up
  Price alert check	Every 5 minutes, in realtime mode
  Weekly news digest (a Kit broadcast)	Mondays at 09:00 UTC

• Email: Nodemailer (Gmail) sends welcome, alert and password-reset emails; Kit sends the weekly digest.

🌍 Market support

Market	Charts (TradingView embeds)	Quotes, watchlist prices, alerts (Finnhub free)
🇺🇸 United States	Live	Yes
Crypto (Binance pairs)	Live	Yes
Forex	Live	No
🇨🇦 Canada, 🇦🇺 Australia	Delayed	No
🇮🇳 India (BSE; .NS symbols chart on BSE), 🇩🇪 Germany	End of day	No
London, Tokyo, Hong Kong, Korea and others	Candles blocked; financials, technicals and profile work	No

The full table, and why some markets are limited, is in MARKET_SUPPORT.md.

🌱 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 professionals and students can use without barriers, knowledge platforms where learning is free forever, communities where every beginner is guided, not judged, and 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.

❤️ 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.
