# 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.

## Tools

- [Mock from OpenAPI spec](https://www.postman.com/tools/mock-from-spec): Mock from OpenAPI spec turns an OpenAPI or Swagger document into a live mock server for every endpoint at once — paste the spec and get a hosted URL that answers each path with an example response, no account and no backend.
- [Editable mock API](https://www.postman.com/tools/editable-mock): Editable mock API lets you build a mock endpoint by hand — choose a method and path, write the JSON response, and generate a live URL you can edit in place, with no account and no backend.
- [Instant mock API](https://www.postman.com/tools/instant-mock-api): Instant mock API spins up a live endpoint that serves realistic JSON for a common resource — pick users, products, orders or posts and get a URL you can call right away, with no account and no backend to run.
- [Mock from CSV/JSON](https://www.postman.com/tools/mock-from-csv-json): Mock from CSV/JSON turns a JSON array or CSV file into a live REST API with working create, read, update and delete endpoints, where data you write persists between calls.
