Compare
Semlith beside grep and ripgrep, Serena and claude-context. What each tool does well, runs you can repeat on Flask, and the published benchmark numbers.
Each page starts with what the other tool does well, runs the same questions on Flask 3.1.3 with both tools, and quotes only the published scorecard. Where the other tool wins, the page says so. Every page says when it was checked and with which versions.
grep and ripgrep
The search most agents already run. Where it beats an index, where it misses, and the SWE-bench Verified numbers.
Serena
IDE-style symbol tools over language servers, beside search from a question.
claude-context
Zilliz’s MCP code search over Milvus, run here with no API key and no account.
Code and documents
One local index over a repository and the PDF, Word and Excel files beside it, searched by Claude Code, Codex or Cursor over MCP, with commands you can run.
grep and ripgrep
Where grep and ripgrep beat an index, where they miss, and what changes for a coding agent. Runs on Flask and the SWE-bench Verified numbers.
