Local-first code analysis — your code never leaves your machine

Most code-intelligence tools are a cloud service wearing a desktop icon: the repository goes up, the insights come down, and somewhere in between your employer's intellectual property sits on someone else's infrastructure. For a lot of codebases that is not a trade-off — it is a hard no from legal, and the tool evaluation ends there.

prism0x2A runs the other way round. Every scan — structure, cycles, churn, coverage — executes on your machine. We never see your codebase or your API key; the only call that reaches us is the licence check every 30 days. That is what makes it usable on the repository your company would never allow near a cloud tool.

What each layer sends — spelled out

The LLM features call your own key, and what that call carries depends on the layer:

The rule behind the split: features that interpret or rewrite code send code. Everything else stays local.

The honest part

Local-first is not a magic privacy wand — if you turn on the layers that read code, bounded excerpts go to the LLM provider you chose, under your key and their terms. The difference is that nothing moves without a feature you switched on, the boundaries are documented above, and the methodology is published rather than asserted.
