Why developers are switching
Postman was great. Then it got bloated, started requiring logins, leaked 30,000 workspaces, and priced out individual developers.
Forced accounts
Since 2023, Postman requires a login to use the app. No account, no access. ApiArk has zero login requirement -- never has, never will.
30,000 workspaces leaked
In December 2024, over 30,000 Postman workspaces were found publicly accessible, exposing API keys, tokens, and secrets. ApiArk stores everything locally on your filesystem.
Resource hog
Postman uses 300-800MB RAM at baseline, with reported spikes up to 15-18GB. Startup takes 10-30 seconds. ApiArk uses ~50MB RAM and starts in under 2 seconds.
Vendor lock-in
Postman uses a proprietary data format tied to their cloud. ApiArk stores collections as plain YAML files on your filesystem -- open them with any text editor, version them with Git.
Switch in 60 seconds
Moving from Postman to ApiArk takes three steps.
Export from Postman
Open Postman, select your collection, click Export, choose Collection v2.1 JSON.
Import into ApiArk
Open ApiArk, press Ctrl+I or click Import, select the exported JSON file.
Done
Your collections, environments, headers, auth, and scripts are converted to YAML. Start working.
