Mock, test and monitor any API. Spin up realistic mock APIs from an OpenAPI spec in seconds, then monitor the real thing using the same collection.
JarAPI removes the wait between “the spec is done” and “the frontend can build against it.” Generate mocks from your OpenAPI file, run contract tests in CI, and keep an eye on latency and uptime from one workspace.
Receive, inspect and replay webhooks locally.
Get a public URL for localhost, inspect every payload and replay events until your handler works.
Your team’s snippet library, wherever you type.
Save, search and share code snippets across your editor, terminal and browser, with offline-first sync.
Docs that stay in sync with your code.
Generate API and library reference straight from source, publish versioned docs and ship changelogs automatically.
