API testing that
lives in your files.
Write .http,
.flow, and
.ws files.
Run HTTP requests, chain flows with assertions, test WebSocket connections — all from a native desktop app.
No accounts. No cloud. No lock-in.
How it works
Three steps to shipping with confidence.
Write plain text files
Create .http files for individual requests, .flow files for chained test sequences, and .ws files for WebSocket sessions. Any folder becomes your workspace.
@baseUrl = https://api.example.com
### Get User
GET {{baseUrl}}/users/1
Authorization: Bearer {{TOKEN}}
### Create User
POST {{baseUrl}}/users
Content-Type: application/json
{ "name": "Alice" } Run with one click
Click ▶ in the gutter or press ⌘Enter. The Flow Runner chains requests, extracts variables with JSONPath, and shows live pass/fail assertion badges.
### Step 1 · Create user
# @name createUser
POST {{baseUrl}}/users
Content-Type: application/json
{ "name": "Alice" }
# @extract userId = $.id
# @assert status == 201
### Step 2 · Verify user
GET {{baseUrl}}/users/{{userId}}
# @assert status == 200
# @assert body contains "Alice" Ship and collaborate
Your tests are files on disk. Commit them. PR them. Diff them. Devs, QA, and PMs all work from the same workspace — no proprietary format, no cloud, no friction.

Everything you need.
Nothing you don't.
Built for developers, QA engineers, and anyone who needs to test APIs without the ceremony.
Text-first editor
Syntax-highlighted .http, .flow, and .ws files powered by CodeMirror 6. Variable autocomplete. One-click gutter run buttons.
Flow runner
Chain requests sequentially. Extract values with JSONPath, assert status and body. Get pass/fail badges and literate test reports.
WebSocket support
Interactive .ws sessions with real-time message timeline. Script send/receive sequences with assertions and extraction.
Git-native
Every request, flow, and env is a plain text file on disk. Diff, branch, PR — collaboration works out of the box.
Cookie jar
Per-environment RFC 6265 cookie jar. Cookies set by responses are sent automatically on future requests. Inspect or clear via the Cookie Manager.
Zero config
Open the app. Open a folder. Click Run. No setup wizard, no account creation, no cloud sync. Just files and results.
