Deploy and Host Crawl4AI on Railway

Crawl4AI is an open-source web crawler and scraper that turns web pages into clean markdown and structured data for LLMs and RAG pipelines.

About Hosting Crawl4AI

This template runs the official unclecode/crawl4ai:latest image, which bundles a headless browser, Redis and the HTTP API on port 11235. A random CRAWL4AI_API_TOKEN is generated for you; the server only accepts connections when a token is set. Find it in the service's Variables tab and send it as Authorization: Bearer . The /playground page offers a UI for trying requests, and /health reports status. The image is large, so the first deploy can take a few minutes, and the browser needs at least 2 GB of RAM.

Common Use Cases

Crawl pages to markdown for RAG and AI agents
Extract structured data with CSS, XPath or LLM strategies
Take screenshots and PDFs of pages through an API

Dependencies for Crawl4AI Hosting

One service; Redis and the browser run inside the same container
