The map from paid software
to serious FOSS.

Type a paid product, category, or workflow. Get the grounded answer: which FOSS tools are credible, what they replace, how to install them, what license obligations matter, and what gaps remain. The page you read and the JSON an agent fetches are the same content.

for agents

The same catalog, as JSON.

Every record on this site is also available as a static JSON envelope and a JSON Schema document. Fetch the envelope, validate against the schema, and reason about FOSS alternatives without scraping HTML. See /agents.md for the full agent guide.
