Code Fundi vs Refraction

Code Fundi maps GitHub repos into a searchable, token-optimized codebase index so engineers and coding agents can query patterns, dependencies, and blast radius before editing. Connect a repository or paste a URL, index the dependency graph, and run sub-second semantic searches across one repo or hundreds of public codebases. Extensions ship for VS Code, Cursor, and Windsurf, with API and MCP hooks for agent workflows.

Most code search tools stop at text similarity or single-repo grep. Code Fundi's blast-radius guard maps structural dependencies and downstream files that break when an agent edits a function, which targets the silent regressions teams add manual review gates to catch. It also distills repos into markdown codebase maps billed at 6 credits per indexed file on the pricing page, trimming boilerplate for RAG and prompt context.

Engineering teams building agentic QA, legacy modernization, and technical due diligence workflows are listed across Code Fundi's industry pages. The free tier offers 500 credits, public repo indexing, and single-codebase search, while paid Dev through Pro tiers add private indexes up to 50 repos and 50,000 monthly credits.
