Markdowner is a fast web service that converts any website into LLM-ready markdown, with optional LLM filtering, detailed responses, and automatic subpage crawling. It runs on Cloudflare Workers with browser rendering and Durable Objects, and can be self-hosted.

Use cases

• convert a webpage to markdown for LLM ingestion
• scrape website content into clean markdown
• crawl subpages and get markdown for each
• filter out boilerplate from web pages before feeding to an LLM
• self-host an alternative to r.jina.ai or firecrawl
• get JSON or plain text extraction of a URL

When to choose

• you need LLM-ready markdown from URLs at low cost
• you want a self-hostable alternative to proprietary scraping APIs
• you need automatic subpage crawling without a sitemap

When to avoid

• you need heavy-duty large-scale scraping with proxies and JS-heavy sites at scale
• you cannot use Cloudflare Workers paid plan for self-hosting
• you need structured data extraction beyond markdown
