Who spent all the tokens? 👀 TokenOps gives multi-agent workflows one shared, run-scoped budget, with policies that can step in before the next model or tool call executes. The result is real-time control over spend and agent behavior while the run is still happening.

Under the hood, there’s a lot to dig into. Agent Terrarium runs on a Rust simulation engine at 20 Hz, with React + Canvas handling the view layer. It supports GitHub Copilot and OpenAI-compatible models, with configurable prompts, awareness levels and working directories. You can also customize avatars, themes and gear through JSON with hot reload, while agents react to world events and take on file-based tasks.
