Import Merging, JSON Breadcrumbs, and Better Performance

Re-importing a file or URL now merges into the workspace it created, with a preview before anything is applied. OAuth 2.0 gets custom headers and params, HTTP Digest is a built-in auth type, gRPC can generate example messages, and Yaak is in the official Arch repos.

🔄 Import into existing workspaces

YK-390·#618

Importing a file or URL now links it to the workspace it created. Re-import the same source and Yaak shows exactly what changed, then merges it in.

Import preview listing added, changed, and ignored requests — The preview before a re-import is applied

Keep your workspace up to date without starting over. Review incoming changes, choose what to bring in, and keep your local edits.

🧭 JSON response breadcrumbs

YK-724·#653 by @vlad-solomon

See your position in a JSON response as you move the cursor through it. Click a breadcrumb to filter the response to that part of the document.

✨ Example gRPC messages

YK-716·#613

The gRPC message editor can generate an example body from the method’s input schema.

Generate Example Message in the gRPC schema menu — Generate Example Message in the schema menu

Fields are filled with placeholder values, including nested messages and common types like Timestamp.

🔑 Custom OAuth 2.0 params

YK-1035·#629

Customize OAuth 2.0 with extra parameters and token request headers to support your provider’s requirements.

Token headers and body params in the OAuth 2.0 Advanced section — Custom headers and parameters in the Advanced section

Values support template tags, so you can pull them from your environment.

🐧 Official Arch Linux package

YK-1081

Yaak is now in Arch Linux’s official extra repository, thanks to community maintainer Jonas! Install it directly with:

pacman -S yaak

⚡ More responsive under load

YK-1087·#642

Yaak now uses a single database writer instead of a pool of connections that could all read and write. This prevents competing writes from exhausting the connection pool, keeping reads fast and the app responsive under load.

	Before	After
Connections used	11	4
Slowest write, 30 sends	98 ms	7 ms
Slowest write, 100 sends	375 ms	4 ms
