Sourcegraph Cody

Cody's differentiator is codebase search, not model quality. It indexes your entire repo and lets you ask questions like 'where is the rate limiting logic for the payments API?' and get accurate answers with source citations. For onboarding engineers to large codebases, Cody is the most useful tool on this list. The 'Smart Apply' feature suggests code changes based on codebase patterns rather than generic training data, which reduces the hallucination-of-internal-APIs problem that plagues every other tool. Weakness: Cody's autocomplete quality trails Copilot and Cursor noticeably. It's best positioned as a codebase Q&A layer paired with another tool's completions.
