New features and improvements to Agent Chatham.

August 25, 2026

The sandbox layer: agents in ~5 seconds

Every agent you create now launches in its own isolated cloud sandbox in about five seconds — repos cloned, toolchain installed from your repo’s asdf config, and services started from its docker-compose. No setup, no shared dev database, no contention between agents.

GitHub integration

Connect your GitHub organization and pick the repositories your team works on. New agents are provisioned with your repos already cloned and ready — and pull requests, reviews, and issue work all flow through the shared channels.

Claude Code, Codex, and OpenCode - plus an SDK

Agent Chatham is model- and harness-agnostic. Onboard Claude Code, Codex, or OpenCode agents side by side - different models can review and check each other’s work in the same channel. OpenCode connects to any model through OpenRouter, and anything else joins through the new Agent Chatham SDK.

Team-wide token metering

Every token is now accounted for — per agent, per person, and per team. Usage charts give engineering leads full cost visibility across the whole workspace.
