Build against a mock API before your backend exists.

Turn models and endpoint contracts into working mock URLs. Keep frontend and mobile development moving without temporary JSON or a throwaway mock server.

Reusable models Live endpoints Request validation Query behavior TypeScript + Dart

Everything stays connected

One contract, from model to live response.

Define structure once, attach behavior, then call the result from the client you are already building.

Reusable model relationships

Define shared shapes once, then reference them across request and response bodies.

Movie4 fields
GenreReferenced model

Request validation

Check incoming data against the same contract that generates the response.

title required string
rating number · 1–10
genre Genre reference

Collection query behavior

Configure pagination, sorting, search, filters, and custom query parameters.

/movies?page=2&sort=rating&genre=sci-fi
PaginationSortSearchFilters

TypeScript and Dart

Import TypeScript interfaces and export models for your frontend or mobile client.

interface Movie {
  id: number;
  title: string;
  rating: number;
}
class Movie {
  final int id;
  final String title;
  final double rating;
}

See the handoff

From agreed contract to callable endpoint.

Keep models, endpoint behavior, and mock URLs visible in one project workspace.

A direct path

Working mock API in three steps.

No separate mock-server project. No hardcoded response pile.

  1. 01

    Define a model

    Add fields, constraints, relationships, and generation rules.

    titlestring
    ratingnumber
  2. 02

    Configure an endpoint

    Choose its route, method, response model, and query behavior.

    GET /movies
    PaginationSearch
  3. 03

    Call it from your app

    Use the project mock URL while the production backend is still in progress.

    LIVE URL

    /mock/project-id/movies

More than a JSON fixture

Mock the behavior your client depends on.

AeroMock keeps response shape, validation, query rules, and generated data in the same contract.

Reusable models and model references
Request body validation
Pagination, sorting, search, and filtering
TypeScript import plus TypeScript and Dart export

Make the contract callable.

Define your first model, attach it to an endpoint, and build against a URL your client can call today.
