Open-source Prompt Lab for side-by-side LLM comparison. Bring your own models (BYO) via Ollama or OpenAI-compatible APIs — no platform-hosted models.

Optional Cloud tier adds synced Tests, Model Sets, and share links on the hosted SaaS. Self-hosting is fully supported. https://ailearntools.freecoop.net/

• Compare up to 6 model panes in one workspace (guest: 4 panes).
• Configure Ollama or OpenAI-compatible endpoints per pane.
• API keys stay in the browser (never uploaded to the server).
• Prompt Principal reference panel (vendor guidance + prompt frameworks).
• Bilingual UI (中文 / EN) and light/dark theme.
• Cloud sync (when signed in): saved Tests, Model Sets, official templates, share links.

See docs/product-strategy.md for the full strategy.

• Next.js 15, React 19, TypeScript
• PostgreSQL + Prisma + Auth.js (Google / GitHub OAuth)
• react-markdown, remark-gfm, rehype-highlight

cp .env.example .env
# Edit .env — set AUTH_SECRET, DATABASE_URL, and at least one OAuth provider

npm install
make db-up          # Postgres in Docker
npm run db:migrate  # apply Prisma migrations
npm run dev

Open http://localhost:3000

Generate AUTH_SECRET:

make gen-secret

OAuth callback URLs (local):

• Google: http://localhost:3000/api/auth/callback/google
• GitHub: http://localhost:3000/api/auth/callback/github

For OAuth debugging with a public URL, use make dev (starts ngrok + Next.js).

Runs Postgres + the Next.js app:

cp .env.example .env
# Set AUTH_SECRET and OAuth credentials in .env

docker compose up --build

App: http://localhost:3000

On first boot, a one-shot migrate service runs prisma migrate deploy (with full Prisma 6 CLI deps), then the app starts.

Note: This project uses Prisma 6. Do not run bare npx prisma (it may install Prisma 7 and fail). Use npm run db:migrate or make db-migrate instead.

• Base URL: http://localhost:11434 (or your Ollama host)
• Model: e.g. qwen2.5:7b

• Base URL: e.g. https://api.openai.com/v1
• Model: e.g. gpt-4.1-mini
• API key: required (stored locally in the browser)

Works with OpenRouter, Together, local vLLM, etc. — any OpenAI-compatible /chat/completions endpoint.
