Get the app

Download BuildEx.

Free and open source. It runs on your machine, operated by the AI you already pay for - your whole company as one git repo you own. Bring your own agent.

macOS is live, both chips. Every release is signed with a Developer ID and notarized by Apple, so it opens without a Gatekeeper warning. Builds land on our GitHub releases page. Linux and Windows are on the roadmap; it's all open source, so you can clone and build from source today.

Or run it from source

Prefer to build it yourself, or on a platform we haven't shipped yet? It's all open source - clone it, install, and the app opens.

# Node 24, pnpm 10.24, git, and a CLI agent signed in
git clone https://github.com/dejankeri/buildex.git
cd buildex
corepack [email protected] install
corepack [email protected] run dev

Before you run it

Bring your own coding-agent CLI and subscription - BuildEx never sets or reads your model keys. Claude Code today; the driver seam is open - other agents welcome as contributions. It requires a Claude Pro subscription or higher.
git under the hood: your brain is a repo of plain markdown you fully own.
Prefer to build from source? It's all open - view on GitHub ↗.
