SourceAnt is open-source infrastructure for engineering knowledge and context. It helps the agents and humans building your software remember how it works.

The open core models code structure, decisions, rules, system topology, API contracts, and review findings behind storage-neutral interfaces. MCP clients can manage and retrieve that context without the hosted service, so the knowledge stays yours whether or not you pay for anything.

Code review is one application of that shared knowledge layer rather than the product itself. Reviews get better when the reviewer knows why the code exists, which is exactly what the layer stores.

Built in Python on FastAPI, model-agnostic through LiteLLM, driven by GitHub webhooks, with a graph index over the topology.
