Why I Left Postman — The Real Cost of a Cloud-First API Client

Description and use

The author left Postman because its cloud-first approach forced data to be stored remotely and required an account. Switching to Voiden allowed API requests to be stored as plain Markdown files locally, fully version‑controlled, and free from cloud dependencies.

Problem

Postman’s cloud-first model forces API testing to rely on a remote account, exposing data, limiting local control, and risking vendor lock‑in.

Outcome

The author achieved full ownership of API definitions, eliminated cloud dependency, and gained a lightweight, Git‑friendly workflow.

Workflow

• 1. Evaluate alternatives (Bruno, Yaak).
• 2. Test Bruno – good local storage but .bru format limits readability.
• 3. Test Yaak – great UI but concerns about future availability.
• 4. Switch to Voiden – import Postman collections into .void files.
• 5. Use reusable blocks for auth, headers, and params.
• 6. Work locally without login or network round‑trip.
• 7. Commit .void files to Git and share via text editors or GitHub.

Evidence

Requests live on disk, Git works properly, and I never felt like I was fighting the tool.

Source

It stores API requests as plain Markdown files.

Source

No account, no login screen, nothing to set up before sending a request.
