About

Code Concert

Features
Read full description

Code Concert lets a team gather around one AI coding agent. Connect to your own Code Concert server (open source) and use a Claude Code / OpenCode / Codex CLI session together, like a chat room. With this app you can โ€ข Receive tool-approval requests, questions from the AI and teammates' proposals as push notifications, and approve or answer on the spot โ€ข Attribution: the AI knows who said what and replies by name โ€ข Team chat: the AI listens to human conversation and only chimes in when a judge model thinks it should. In conductor mode only instructions approved by the admin are executed โ€ข Whiteboard: a board shared with agents on other machines and with teammates โ€ข Connect and log in by scanning the QR shown on your PC โ€” no typing Requirements โ€ข A Code Concert server (Node.js 20+, one-line install from https://code-concert.com) โ€ข Claude Code, Codex or OpenCode, signed in with your own account or your organization's API key Pricing The app is free. Fees for Claude Code / Codex / OpenCode themselves are not included โ€” you use your own accounts. Code Concert Cloud (share URLs, cloud whiteboards) is free during the preview; paid plans will be announced in advance. For rooms shared by a team we recommend API keys or conductor mode, where the admin approves every instruction; personal-plan logins are meant for the account holder.
