ToolbitAPI Request Builder and HTTP Client
Fire a GET, POST, PUT, PATCH, or DELETE, set headers and a body, and read the response with formatting and timing. No account, no workspace sync, no telemetry.
What the API Request Builder does
- All common HTTP verbs with custom headers and request bodies.
- Response viewer with status, headers, timing, and pretty-printed JSON.
- Request history so you can replay the call you made a minute ago.
- Nothing syncs to a cloud workspace — requests stay on your machine.
How to use it
- Enter the URL and pick the HTTP method.
- Add headers and a request body if the endpoint needs them.
- Send, then read the formatted response and timing breakdown.
Why it runs locally
Toolbit has no backend. The API Request Builder is implemented with standard browser APIs, so your input is processed in the tab and never uploaded, logged, or retained. That is what makes it safe to paste real data into — and it is also why the tool keeps working with the network disconnected, once you have installed Toolbit as an app.
Frequently asked questions
- Why do some requests fail with a CORS error?
- The request runs from your browser, so it obeys the same-origin policy. Endpoints that do not send permissive CORS headers need a proxy or a desktop HTTP client.
- Is this a Postman replacement?
- For everyday endpoint checks, yes — and without an account or cloud sync. For team collaboration, mock servers, and shared collections, Postman still does more.
- Are my tokens sent anywhere but the target API?
- No. Headers and bodies go only to the endpoint you type. Toolbit has no backend of its own.
