Can Toolbit replace Postman?

For quick endpoint checks and debugging, comfortably. For shared collections, scripted test suites, and mock servers, no — those are Postman's core and Toolbit does not implement them.

Why does my request fail with a CORS error in Toolbit?

The request runs from the browser and obeys the same-origin policy. Endpoints without permissive CORS headers need a native client or a proxy.

Does Toolbit require an account?

No. There is no account, no sign-in, and no cloud sync — the tool has no backend.

Toolbit vs Postman

Postman is a full API development platform: collections, environments, mock servers, monitors, and team collaboration. Toolbit's API request builder covers the part most developers use most days — send a request, read the response — without an account or a cloud workspace.

What Toolbit does well

Open a tab, type a URL, add headers, send, read the formatted response with status and timing. Nothing syncs anywhere, nothing phones home, and there is no sign-in wall between you and a GET request. The response drops straight into the JSON formatter or the JWT decoder when you need to look closer.

What Postman does that Toolbit does not

Shared collections, environment and variable management, scripted pre-request and test assertions, mock servers, contract testing, monitors, and team workflows. If your API testing is a collaborative, versioned artefact, Postman is the right tool and Toolbit is not trying to replace it.

Privacy and account requirements

Postman is a cloud product; collections sync to its servers unless you configure otherwise, and it requires an account. Toolbit has no backend at all — requests go from your browser to the endpoint you typed and nowhere else, and there is nothing to sign up for.

The browser trade-off

Because Toolbit's client runs in the page, it obeys CORS. Endpoints that do not send permissive CORS headers cannot be called from the browser build; Postman, as a native app, has no such restriction. That is the main practical limitation to be aware of.
