炒股软件居然也搞开源了，这操作属实有点离谱。

OpenStock 在 GitHub 上 star 已经 16900+，一个开源项目，把付费行情软件里那些要收你钱的功能，全给塞进一个免费平台，还放话永久免费。

它想干的事特别直接：一分钱不掏，也能用上一整套看盘工具。我拆开给你说：

1️⃣ 实时股价，行情随时盯着

2️⃣ TradingView 的 K 线，专业软件同款

3️⃣ 技术指标，该有的都有

4️⃣ Reddit、X、财经新闻、Polymarket 的市场情绪，全揉进一个界面，省得你开一堆网页来回切

最让我买账的是 Watchlist 这块。把持仓加进去，Gemini 会顺着你关注的方向，每天生成一份 AI 新闻摘要，直接推到你邮箱。

说白了，盯盘、看新闻、刷情绪、整理信息流这些事，它基本都给你捏一块儿了，一个界面搞定。

技术栈也不含糊，Next.js、TypeScript、MongoDB，还挂着 GitHub Trending 当日第一的牌子，不是那种随手写完就扔的玩具。

不过我得提一句，它自己也讲了，OpenStock 是社区搭起来的，不是券商，行情数据可能有延迟，里面的东西也不构成任何投资建议，你自己心里有数就行。

想上手的自己去扒源码：

OpenStock

Markets, minus the paywall. OpenStock is a free, open-source alternative to expensive market platforms: track prices, watch the whole market and dig into company insights. Use it at openstock-ods.vercel.app, or run your own copy with every feature.

❤️ 13,000+ people use OpenStock for free. Help keep it that way: sponsor from $5 a month, or read how OpenStock is funded.

OpenStock is community-built and not a brokerage. Market data may be delayed depending on the provider and your setup. Nothing here is financial advice.

• 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:

⚙️ Tech stack

🤸 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:

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.

🌱 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.

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

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).

Can’t sponsor right now? Pick a good first issue, star the repo, or share OpenStock with someone who pays too much for a terminal.
