About

What is AOTG?

AOTG (Api on the Go) is a web platform for generating test data and disposable mock APIs. Use it when you need realistic JSON for frontends, demos, integration tests, or local development — without standing up a real backend. Nested objects and arrays, OpenAPI import, and CSV export keep payloads close to your real API shapes.

Workflow

How it works

Define a schema Pick related fields, write nested custom JSON, or import an OpenAPI schema for the shape your app expects.
Generate data Fill records with random values, locales, quantity controls, seeds for CI, then download JSON or CSV.
Publish a mock API Get a unique REST URL with method and auth. Anonymous endpoints expire after one hour; registered accounts keep mocks until deleted.
Call it from your app Copy the URL or curl snippet and keep building while the data endpoint stays warm.
