Developer tooling
Open-source beta
APIWatch
Record external API contracts and detect breaking structural changes in CI.
A Rust CLI, available under Apache-2.0. Observed contracts verify sampled structure, not every possible response.
Declared OpenAPI 3.0/3.1 and observed JSON are distinct evidence paths. Values and business behavior are not verified. This is not an uptime monitor. Swagger 2.0 and path-level references are unsupported; some complex schemas exceed the resolution budget.
Declared OpenAPI fixture
$ apiwatch diff old.openapi.yaml new.openapi.yaml
Breaking changes- GET /users: response 200 application/json field items.name removed- POST /users: request application/json field items.email added as requiredWarnings- GET /nested: response 200 application/json field items.items format changed from uuid to date-time

Declared OpenAPI diff. The command uses illustrative filenames; the findings match a committed fixture. Breaking changes return exit code 1.
Fixture source: old contract and new contract; findings rendered by the CLI’s committed array-item fixture test.

The studio
Make the complex easier to work with.
Different domains, a shared approach: build focused software, make the evidence understandable, and keep improving the details that matter.
Start with a useful job.
Give each product a clear purpose and a practical place in someone’s day.
Keep the evidence close.
Show the context behind a number, an estimate or a change, so people can judge it for themselves.
Be clear about the stage.
Make access, limitations and the next useful action easy to find.
Watch the studio film
A silent editorial film: a blue paper arch, cut templates, a folded-paper food still life, ordered sheets and a shared workbench. It closes with “Four tools on one bench” and the four product names. Generated editorial artwork; not product footage.
