FreeCrawl SEO Tool

An open-source desktop SEO crawler offered as a free, cross-platform alternative to Screaming Frog. It targets crawls of over a million URLs on a single machine, with a dense table-style interface, more than 200 SEO issue checks and no native dependencies. Beyond the audit itself, it can run your own AI prompts on each page through OpenAI, Claude or Ollama with your choice of model and system prompt, and it tracks token usage per provider. Spelling checks extend to languages that LanguageTool has no rules for, such as Turkish. Several projects can be opened side by side, and any URL Details table can be exported on its own, or the whole project saved as a password-protected encrypted file. A built-in MCP server with over 100 tools lets AI agents like Claude drive crawls live and read every result. Builds exist for Apple Silicon and Intel Macs. MIT licensed and written in TypeScript.
