Mock API Tools

Need a fake backend before the real one exists? Get a live mock endpoint in one click, generate one from an OpenAPI spec, turn a CSV or JSON file into a full CRUD API, or host an editable JSON response at a URL you control — pick the shape of mock you actually need.

Mock from OpenAPI spec

Paste a spec, mock every endpoint at once.

Editable mock API

Paste JSON or text, get an editable endpoint.

Instant mock API

Pick a resource, get a live mock endpoint.

Mock from CSV/JSON

Turn JSON or CSV into a live REST API with working writes.
