Firecrawl Developer Index
The Firecrawl Developer Index is now available, a specialized index for coding agents. It covers 70M+ artifacts across READMEs, external documentation, issues, pull requests, and OpenAPI specs, with semantic retrieval and metadata filters. Your AI agents answer questions about code behavior, API contracts, error messages, and known bugs from primary sources instead of general web pages.
- Highest recall of any major coding-specific index. Scores 0.63 recall@10 across the 1,179 real developer queries in our open DevDex benchmark, ahead of every other provider we tested.
- 70M+ artifacts. READMEs, docs, issues, PRs, and OpenAPI specs from the most popular public repos and documentation sites, refreshed continuously with most sources updated daily.
- Answers with passages. Every result carries a stable id, a url, and the matched passages in markdown, so your agents act on the answer without a second scrape.
- Rich filters in the API. Scope by result type, repository, documentation source, language, topic, license, minimum stars, and more. These are API-only; agents on the CLI and MCP perform best without them.
- Keyless to start. No API key needed to try it; add one for higher rate limits. A developer search costs 2 credits per 10 results.
- Available everywhere you build. Query it through the API at
/search/developer, plus the CLI, MCP, and SDKs, or install the companion skill withnpx -y firecrawl-cli@latest setup developer-index.
