Pros & Cons
Sourcery
- Genuinely deep Python-specific refactoring analysis, more focused than general-purpose multi-language tools
- Real-time IDE feedback in VS Code and PyCharm speeds up the refactoring workflow
- Extends to JavaScript for PR review, providing some multi-language coverage beyond pure Python
- Reported pricing varies across sources ($10-$18/developer/month for Pro) — verify current rates directly
- Narrower Python focus means less value for teams working primarily in other languages
- Team tier ($30/developer/month) required for unlimited security issue tracking
ECC
- Massive community adoption — over 200,000 GitHub stars and 170+ contributors
- Genuinely solves cross-tool configuration fragmentation for developers using multiple AI coding assistants
- Free tier available for public repo analysis before committing to a paid plan
- Full-depth support is strongest for Claude Code, with other harnesses receiving capability-limited adapters
- Private repo analysis and higher usage limits require the paid Pro tier
- Fast-moving space means ECC and its supported harnesses will likely keep evolving quickly
