API mocks, testing, contracts, and debugging

Build and test APIs without waiting on the real thing

Use it to create enterprise-grade API mocks

HTTPStatus gives developers one focused place to create realistic API mocks, exercise requests, validate contracts, and investigate failures.

MOCKS FIRSTTESTINGCONTRACTSOPERATIONS

Describe the mock you need. Let AI draft the endpoint.

A practical entry point after the platform promise: describe a small API dependency and HTTPStatus will open an editable mock draft in the app.

Draft without signup. Save it after review in the app.

What goes in, what comes out, and what the result can prove.

One artifact can move through the platform

cURL → normalized request → mock → assertions → saved evidence

Three checks before the result becomes a decision.

01

Start with input

Keep the original artifact visible.

02

Create a runnable result

A mock or request should work before it is saved.

03

Preserve the handoff

Carry evidence into the next workflow instead of copying conclusions.

What this workflow does not prove.

Follow the engineering outcome, not a list of generic tools.

Every important public page is linked here with enough context to understand the next workflow before opening it.

Before you put it into a real workflow.

Do I need an account?

No for the public product pages and basic entry flows. An account is used when you want saved workspaces, history, collaboration, or scheduled operations.

What can I start with?

A URL, cURL command, OpenAPI document, JSON payload, webhook, trace, log excerpt, or a description of the API you need.

Is this only a mock server?

Mocks are the fastest starting point, but the platform also covers API testing, contracts, automation, chaos, security review, and operational diagnostics.

Start with one concrete API problem.

Keep the first step small. Move into a workspace when the result deserves to be saved, repeated, or shared.
