Berd

What is Berd?

Block's open-source desktop workspace for running AI agents.

Who is Berd best for?

Berd is best for engineers and designers who want one desktop app for AI agents across projects, with any model.

• People who switch between models

  You connect the AI provider you want and can change models per task, so small jobs do not have to run on the most expensive model.

• Building a crew of agents

  It ships with ready-made agents such as a blunt critic and a writing helper that learns your style, and you can make your own with skills and a personality.

• Work tied to local projects

  Projects link to the folders and repos you already use, so agents see the right files and past sessions are easy to pick up again.

• Companies that want their own build

  The Apache-2.0 source lets an organization package an internal edition with managed provider settings and private resources.

How much does Berd cost?

Berd is free and open source under the Apache-2.0 license, so the only cost is the AI provider whose models you connect to it.

Berd has no paid tiers or subscriptions. Model use is billed by whichever AI provider you connect, so the running cost depends on the models you pick. Installers are on the project's GitHub releases page, and companies can build their own internal edition from the source code. Full pricing on github.com. We checked these prices on 27 Sep 2026.
