Sonde translates to "probe" in French and Italian — and that's exactly what it does to your code. We believe you shouldn't have to hold an entire system in your head just to contribute. Code has inherent structure — functions call functions, services depend on services — but that structure is usually invisible. Search tools just find strings, and AI guesses based on text.

We built Sonde to uncover the map that’s been missing. By turning your codebase into a living, queryable graph, we help humans and AI agents actually understand how your software fits together.
