The API client your team lives in.

Not a mockup. This is the actual app.

Every screenshot below is a real, unedited screen from HTTP Titan — a live request, a live response, a live test run.

Method-aware everything

GET, POST, PUT, PATCH and DELETE carry their own colour through the whole UI — you read the verb before you read the URL.

Always-visible response

Status, timing and size sit on one line, always in view. No hunting through tabs to learn what came back.

Collections & history

Organise requests into collections, and every send is kept in history so you can replay or diff what you ran.

Environments & secrets

Swap base URLs and tokens per environment; secret variables stay masked and never leak into shared views.

Scripting & tests

A real JavaScript runtime on every request and response — write pre-request setup and post-response assertions.

Built for teams

Share collections and environments with your team, with roles that control who can see and change what.

From URL to assertion in four moves.

No setup ceremony. Open Titan and you are already composing the first request.

// runs after every response
const body = await res.json()
 
test("status is 200", () => {
  expect(res.status).toBe(200)
})
 
test("returns a token", () => {
  expect(body.token).toBeDefined()
})

Start free, scale when you're ready.

Create your account in seconds and start sending requests. Bring in a team or your whole organization when you need to.

We build the tool we wanted to live in.

HTTP Titan started as an internal tool — a faster, denser, more honest way to work with HTTP. We were tired of API clients that hid the numbers that matter and got in the way more than they helped.

Today it's a team-first client for building, documenting and testing APIs — fast, dense, and honest about what's happening on the wire.
