GitNexus

GitNexus turns a codebase into a knowledge graph that coding agents can query for exact structural information, such as which functions call a given piece of code or which services depend on an API, instead of relying on embedding-based search that can miss or misjudge relationships. It ships with agent skills for exploring, debugging, impact analysis, and refactoring, and can flag when a change in one repository will break something in another before that change is merged.

Built by Akon Labs, GitNexus is open source and had gathered around 45,000 GitHub stars by the time it launched on Product Hunt in late August 2026. The company reports that coding agents connected to GitNexus complete benchmark tasks at roughly half the cost of running without it, since agents spend less time re-reading code to reconstruct context that the graph already has.
