# AnakinScraper OSS [![CI](https://github.com/Anakin-Inc/anakinscraper-oss/actions/workflows/ci.yml/badge.svg)](https://github.com/Anakin-Inc/anakinscraper-oss/actions/workflows/ci.yml) [![License: AGPL-3.0](https://img.shields.io/badge/License-AGPL--3.0-blue.svg)](LICENSE) [![Go](https://img.shields.io/badge/Go-1.25-00ADD8?logo=go&logoColor=white)](https://go.dev) [![Python](https://img.shields.io/badge/Python-3.11-3776AB?logo=python&logoColor=white)](https://python.org) [![Docker](https://img.shields.io/badge/Docker-Ready-2496ED?logo=docker&logoColor=white)](docker-compose.yml) [![React](https://img.shields.io/badge/Web_UI-React_19-61DAFB?logo=react&logoColor=white)](webapp/) The open-source web scraping API for AI. Turn any website into LLM-ready markdown or structured data. Self-host with a single command. No cloud dependencies. Powers RAG pipelines, AI agents, and data extraction at scale. ```bash git clone https://github.com/Anakin-Inc/anakinscraper-oss.git && cd anakinscraper-oss && make up # Scrape any website — one curl, full result: curl -s -X POST http://localhost:8080/v1/scrape \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com"}' | jq .markdown ``` ## Why AnakinScraper? | | AnakinScraper | Firecrawl | Crawlee | Scrapy | |---|---|---|---|---| | Anti-detect browser | Camoufox (Firefox) | Headless Chrome | Playwright | No | | Smart proxy selection | Thompson Sampling (ML) | Round-robin | Manual | Manual | | Zero-config start | `go run` — no DB needed | Docker required | npm install | pip install | | Single binary | Go — one 30MB binary | Node.js | Node.js | Python | | Handler chain fallback | HTTP → Browser → API | Single mode | Single mode | Single mode | | Structured JSON (AI) | Gemini extraction | LLM extraction | No | No | ## Features - **Handler chain with fallback** — HTTP fetch → anti-detect browser → external API. Each handler tries in order; if one fails, the next picks up automatically. Most pages resolve on the free local HTTP handler — paid APIs are only called for the ~5% that actually need them. [Docs →](docs/handlers.md) - **Custom API handlers** — plug in any third-party scraping service as a chain fallback. Only invoked when local handlers fail — saves 90%+ on API costs vs routing everything through a paid service. Built-in [anakin.io](https://anakin.io) handler included. [How to add your own →](docs/handlers.md#example-adding-a-third-party-api-handler) - **Domain configs** — per-domain scraping strategies: choose which handlers to use, set timeouts, retries, custom headers, block domains, and validate content with pattern matching. [Docs →](docs/domain-configs.md) - **Failure detection** — define failure patterns and required patterns per domain. If the scraped content matches a failure pattern (e.g. CAPTCHA page) or misses a required pattern, the job auto-retries with the next handler. [Docs →](docs/domain-configs.md#failure-detection) - **Anti-detect browser** — [Camoufox](https://github.com/daijro/camoufox) (anti-detect Firefox) with realistic fingerprints, not headless Chrome. [Docs →](docs/handlers.md#browser-handler) - **Proxy auto-select** — [Thompson Sampling](https://en.wikipedia.org/wiki/Thompson_sampling) picks the best proxy per domain, learning from success/failure in real time. [Docs →](docs/proxy-pool.md) - **Structured JSON extraction** — use Gemini AI to extract structured data from any page (bring your own API key) - **Sync + async + batch API** — `POST /v1/scrape` for instant results, `/v1/url-scraper` for async with polling, batch up to 10 URLs - **LLM-ready markdown** — automatic boilerplate removal, clean content extraction. Feed directly into RAG pipelines, Claude, GPT, or any LLM without preprocessing - **Web dashboard** — built-in React UI for scraping, job tracking, domain config management, and proxy monitoring - **Zero-config mode** — run with just Go, no database needed. Or use Docker for the full stack - **Self-contained** — no Redis, no AWS, no message queues. Single Go binary. Optional PostgreSQL for persistence ## Quick Start (no Docker, no database) Just Go 1.25+. Two commands: ```bash cd server && go run cmd/server/main.go # In another terminal: curl -s -X POST http://localhost:8080/v1/scrape \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com"}' | jq .markdown ``` Jobs are stored in memory (lost on restart). For persistence, set `DATABASE_URL`. For JavaScript-heavy sites, add the browser service via Docker. ## Self-Host (Docker — full stack) ### Prerequisites - [Docker](https://docs.docker.com/get-docker/) and Docker Compose ### Start ```bash git clone https://github.com/Anakin-Inc/anakinscraper-oss.git cd anakinscraper-oss make up ``` That's it. Three containers start: | Service | Port | Description | |---------|------|-------------| | Server | 8080 | REST API + worker pool | | Browser Service | 9222 | Camoufox anti-detect browser (WebSocket) | | PostgreSQL | 5432 | Job storage | ### Web Dashboard A built-in web UI is included for visual scraping, job tracking, and configuration: ```bash cd webapp && npm install && npm run dev ``` Open [http://localhost:3000](http://localhost:3000) — the dashboard proxies API calls to the server on port 8080. Pages: **Dashboard** (health + quick scrape) | **Scrape** (sync/async/batch with live results) | **Jobs** (tracked history with status filters) | **Domain Configs** (CRUD with handler chain management) | **Proxy Scores** (Thompson Sampling performance) ### Scrape a URL **Synchronous** (recommended for getting started): ```bash curl -s -X POST http://localhost:8080/v1/scrape \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com"}' | jq . ``` One request, full result back. No polling. Timeout: 30 seconds by default (configurable via the `timeout` request field, max 120 seconds). **Asynchronous** (for long-running scrapes): ```bash # Submit curl -s -X POST http://localhost:8080/v1/url-scraper \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com"}' # Poll for result curl -s http://localhost:8080/v1/url-scraper/JOB_UUID | jq . ``` **With AI-powered JSON extraction** (requires `GEMINI_API_KEY`): ```bash curl -s -X POST http://localhost:8080/v1/scrape \ -H "Content-Type: application/json" \ -d '{"url": "https://example.com", "generateJson": true}' | jq .generatedJson ``` No API keys required for the scraper itself. Just JSON in, results out. ## Architecture ``` ┌─────────────────┐ │ Your App │ │ (cURL / CLI) │ └────────┬────────┘ │ HTTP ▼ ┌─────────────────┐ ┌──────────┐ │ Server │────────▶│ Gemini │ │ (Go/Fiber) │ optional│ (JSON) │ │ Port 8080 │ └──────────┘ └──┬──────┬───┬──┘ │ │ │ ┌──────────┘ │ └────────────┐ ▼ ▼ ▼ ┌──────────┐ ┌──────────────┐ ┌──────────────┐ │ Storage │ │ Browser │ │ API Handler │ │ Postgres │ │ Service │ │ (anakin.io │ │ or memory│ │ (Camoufox) │ │ or custom) │ │(optional)│ │ (optional) │ │ (optional) │ └──────────┘ └──────────────┘ └──────────────┘ ``` The server is a single Go binary that runs with zero dependencies. Optionally add PostgreSQL for persistence, the browser service for JavaScript-heavy sites, and API handlers for hard-to-scrape sites. Workers execute the handler chain (HTTP → browser → API fallback), convert HTML to markdown, and optionally extract structured JSON via Gemini. ## API Reference See [docs/API.md](docs/API.md) for the complete API reference. Quick overview: | Method | Endpoint | Description | |--------|----------|-------------| | `POST` | `/v1/scrape` | **Sync** — scrape a URL and get the result back directly (default 30s timeout, configurable via `timeout` field, max 120s) | | `POST` | `/v1/url-scraper` | **Async** — submit a scrape job, returns job ID | | `GET` | `/v1/url-scraper/:id` | Poll for async job result | | `POST` | `/v1/url-scraper/batch` | Batch scrape up to 10 URLs | | `GET` | `/v1/url-scraper/batch/:id` | Poll for batch result | | `POST` | `/v1/domain-configs` | Create a per-domain scraping config | | `GET` | `/v1/domain-configs` | List all domain configs | | `GET` | `/v1/proxy/scores` | View proxy Thompson Sampling scores | | `GET` | `/v1/telemetry/status` | View telemetry state and next payload ([details](TELEMETRY.md)) | | `GET` | `/health` | Health check | ### Request Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `url` | string | **required** | URL to scrape | | `useBrowser` | bool | `false` | Skip HTTP handler, go straight to browser | | `generateJson` | bool | `false` | Extract structured JSON via Gemini AI (requires `GEMINI_API_KEY`) | | `timeout` | int | `30` | Seconds to wait for a sync result (max `120`; sync endpoint only) | ### Response ```json { "id": "550e8400-...", "status": "completed", "url": "https://example.com", "html": "<html>...</html>", "cleanedHtml": "<main>...</main>", "markdown": "# Page Title\n\nContent...", "generatedJson": { "status": "success", "data": {"title": "Page Title", "content": "..."} }, "durationMs": 1234 } ``` `generatedJson` is only present when `generateJson: true` and `GEMINI_API_KEY` is configured. ## Handler Chain Each scrape job goes through the handler chain. On failure, it falls back to the next handler: ``` HTTP Handler (fast, ~200ms) ──fail──▶ Browser Handler (Camoufox) ──fail──▶ API Handler (optional) ``` **HTTP Handler** — direct HTTP GET with a browser user-agent. Handles static HTML, server-rendered pages. No browser overhead. **Browser Handler** — connects to [Camoufox](https://github.com/daijro/camoufox) (anti-detect Firefox) over WebSocket via Playwright protocol. Full JavaScript rendering, network-idle detection, realistic browser fingerprints. Handles SPAs, lazy-loaded content, and sites with anti-bot protection. **API Handler** (optional) — delegates to an external scraping API when local handlers fail. Set `ANAKIN_API_KEY` to enable the built-in [anakin.io](https://anakin.io) fallback for hard-to-scrape sites (Cloudflare, DataDome, etc.). See [Adding Custom API Handlers](#adding-custom-api-handlers) below. ### Adding Custom API Handlers The API handler pattern makes it easy to integrate any third-party scraping service as a chain fallback. The built-in anakin.io handler (`server/internal/handler/api.go`) is a working example — copy and modify it for your provider: 1. **Copy** `api.go` to `my_provider.go` 2. **Add a constructor** like `NewAnakinHandler` — set your provider's URL, auth header name, and response format 3. **Register** in `main.go`: ```go if cfg.MyProviderAPIKey != "" { handlers = append(handlers, handler.NewAPIHandler(handler.APIHandlerConfig{ Name: "my-provider", APIURL: "https://api.my-provider.com/scrape", APIKey: cfg.MyProviderAPIKey, AuthHeader: "Authorization", // or "X-API-Key", "Bearer", etc. })) } ``` 4. **Add env var** to `config.go`: `MyProviderAPIKey: os.Getenv("MY_PROVIDER_API_KEY")` API keys always come from environment variables — never hardcoded. The handler only activates when its key is set. ### Extending the Chain Implement the `ScrapingHandler` interface: ```go type ScrapingHandler interface { Name() string CanHandle(ctx context.Context, req *HandlerRequest) bool Scrape(ctx context.Context, req *HandlerRequest) (*ScrapeResult, error) IsHealthy() bool } ``` See [examples/custom-handler/](examples/custom-handler/). ## Configuration All configuration via environment variables: | Variable | Default | Description | |----------|---------|-------------| | `PORT` | `8080` | Server port | | `DATABASE_URL` | — | PostgreSQL connection string (optional — uses in-memory storage when not set) | | `BROWSER_WS_URL` | `ws://localhost:9222/camoufox` | Browser service WebSocket URL | | `BROWSER_TIMEOUT` | `60` | Page navigation timeout (seconds) | | `BROWSER_LOAD_WAIT` | `2` | Extra wait after page load (seconds) | | `WORKER_POOL_SIZE` | `5` | Concurrent scrape workers | | `JOB_BUFFER_SIZE` | `100` | Job queue buffer size | | `JOB_TIMEOUT` | `120` | Max job duration (seconds) | | `PROXY_URL` | — | Default HTTP proxy for the HTTP handler | | `PROXY_URLS` | — | Comma-separated proxy pool for auto-selection (Thompson Sampling) | | `GEMINI_API_KEY` | — | Google Gemini API key for structured JSON extraction ([get one free](https://aistudio.google.com/apikey)) | | `ANAKIN_API_KEY` | — | [anakin.io](https://anakin.io) API key — enables hosted API as chain fallback for hard-to-scrape sites | | `LOG_LEVEL` | `INFO` | Log level (DEBUG, INFO, WARN, ERROR) | | `TELEMETRY` | `on` | Anonymous usage telemetry (`off` to disable — see [TELEMETRY.md](TELEMETRY.md)) | | `TELEMETRY_URL` | — | Custom telemetry endpoint (defaults to `https://telemetry.anakin.io/v1/collect`) | | `DISABLE_HOSTED_HINTS` | — | Set to `true` to suppress hosted service tips in error messages | ## Project Structure ``` anakinscraper-oss/ ├── server/ # Go server (API + workers) │ ├── cmd/server/ # Entry point │ └── internal/ │ ├── config/ # Environment config │ ├── models/ # Data types │ ├── worker/ # Channel-based worker pool │ ├── handler/ # Scraping handlers (HTTP, Browser) │ ├── converter/ # HTML → Markdown │ ├── gemini/ # Gemini AI JSON extraction │ ├── domain/ # Domain configs + failure detection │ ├── store/ # Job storage (PostgreSQL or in-memory) │ ├── proxy/ # Proxy pool + Thompson Sampling │ ├── telemetry/ # Anonymous usage telemetry │ ├── processor/ # Job processing │ └── http/ │ ├── handlers/ # API request handlers │ └── router/ # Route registration ├── browser-service/ # Camoufox anti-detect browser server ├── webapp/ # React web dashboard (Vite + Tailwind) ├── openclaw-skill/ # OpenClaw skill wrapper ├── examples/ # Usage examples ├── docker-compose.yml # Full stack (3 containers) ├── scripts/init-db.sql # Database schema └── .env.example # Config template ``` ## Development ### Running Locally (without Docker) **Minimal (Go only):** ```bash cd server && go run cmd/server/main.go ``` No database, no browser service. HTTP handler scrapes static sites. Jobs stored in memory. **Full local stack (Go + Python + PostgreSQL):** ```bash # Terminal 1: PostgreSQL docker compose up postgres -d # Terminal 2: Browser Service (for JS-heavy sites) cd browser-service && pip install -r requirements.txt && python server.py # Terminal 3: Server with persistence cd server && DATABASE_URL="postgres://postgres:postgres@localhost:5432/anakinscraper?sslmode=disable" go run cmd/server/main.go ``` ### Running Tests ```bash cd server && go test ./... ``` ### Building ```bash cd server && go build -o server ./cmd/server ``` ## CLI Use the [Anakin CLI](https://github.com/Anakin-Inc/anakin-cli) to scrape from your terminal. It works against both self-hosted and the [hosted API](https://anakin.io): ```bash # Install pip install anakin-cli # Scrape via your local instance (no API key needed) anakin scrape "https://example.com" --api-url http://localhost:8080 # Or set it as your default export ANAKIN_API_URL="http://localhost:8080" anakin scrape "https://example.com" # Extract structured JSON anakin scrape "https://example.com" --format json --api-url http://localhost:8080 # Batch scrape anakin scrape-batch "https://example.com" "https://httpbin.org/html" --api-url http://localhost:8080 ``` The same CLI also supports **AI web search** and **deep research** via the hosted API — [get a free API key](https://anakin.io/dashboard) to unlock those features. See the [anakin-cli repo](https://github.com/Anakin-Inc/anakin-cli) for full usage. ## Integrations ### OpenClaw Skill Use AnakinScraper as an [OpenClaw](https://openclaw.ai) skill: ```bash cp -r openclaw-skill ~/.openclaw/workspace/skills/anakinscraper ``` See [openclaw-skill/SKILL.md](openclaw-skill/SKILL.md). ## Self-Hosted vs Hosted This repo gives you the full scraping engine. [anakin.io](https://anakin.io) adds the infrastructure you'd otherwise build yourself: | Feature | Self-Hosted (this repo) | Hosted ([anakin.io](https://anakin.io)) | |---------|------------------------|----------------------------------------| | Sync + async scraping | Yes | Yes | | Batch scraping | Yes | Yes | | Anti-detect browser | Yes | Yes | | Structured JSON extraction | Yes (bring your own Gemini key) | Yes (built-in) | | Domain configs | Yes | Yes | | Proxy auto-selection | Yes (bring your own proxies) | Yes (195 countries included) | | Geo-targeted proxies | — | 195 countries | | AI web search | — | Yes | | Deep agentic research | — | Yes | | Zero infrastructure | — | Yes | **Already self-hosting?** Switch to hosted with one line — same API, same CLI: ```bash anakin login --api-key "ak-xxx" # get your key at anakin.io/dashboard anakin scrape "https://example.com" # now routes through hosted ``` [Try it free →](https://anakin.io) ## Community Join our [Discord](https://discord.com/invite/T57dHrdT8u) for questions, discussion, and support. ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md). ## License [AGPL-3.0](LICENSE) — free to self-host.
