Give your AI agents Apps.
Penkra gives the agents you already use Apps to work with your files, browser, and tools—all from one desktop workspace.
Free and open source · macOS, Windows, and Linux

Apps make agents useful for your work.
Each App can add an interface you use, capabilities your agents call, and skills that teach them how. Start with Files + Editor and Browser, then install more.

Run tasks in parallel—not one by one.
Each thread runs independently. See what’s working, what needs approval, and what’s done—without opening every conversation.

Files, browser, and conversations—together.
Open a file, check a page, and talk to an agent side by side. Everything stays attached to the thread where the work belongs.
Use the agents you already know.
Connect Claude, Codex, Cursor, Grok, Droid, Kilo, Pi, GitHub, and OpenCode—then choose the right one per thread.
Nine agents. One workspace.
Connect one or several. Choose per thread.
Apps only see what you hand them.
An App cannot browse your conversations, folders, settings, or other Apps. It gets only the input an agent passes and the permissions you approve.
Free, open source, and built to extend.
Inspect the code, contribute to Penkra, or build Apps with familiar web technologies and the open Agent Skills format.
