Yaak

A Postman alternative for everyday API work

Keep requests on your computer, reuse response values without scripts, and collaborate through Git. No account required.

Free for personal use · 30-day commercial trial

No account required

Keep response history on your device alongside requests and environments.

Built-in request chaining

Select a value from another response. If no response exists yet, Yaak sends that request first.

One file per request

Change one request and review its YAML diff without sifting through a whole collection.






Your requests, without an account

Keep requests and environments locally, without signing in. The desktop app sends requests from your computer, with optional proxy settings.

This comparison covers the desktop app. The browser app uses a proxy.

    Dynamic requests, less scripting

    Generate IDs, format dates, and reuse login responses with functions inside the request editor. Plugins add functions such as Faker data.

      API changes, reviewed in Git

      Save requests as YAML files with Directory Sync. Review diffs and commit in Yaak, then share changes through your team’s pull requests. There’s no Yaak cloud workspace to keep in sync.

        Share requests. Protect secrets.

        Enable workspace encryption to protect tokens, passwords, and other sensitive values, including in synced YAML. Teammates decrypt them with the workspace key you share outside Git. The OS keychain protects your keys. Environments stay local unless you mark them sharable.

          Team pricing, up front

          Licenses can be reassigned. SSO and provisioning are included. You can also build Yaak’s MIT-licensed source for commercial use.

          Prices exclude tax and add-ons. Budget for any Postman capabilities you’d still need alongside Yaak.
