Bulletproof ctrl

About Bulletproof ctrl

ctrl, by Bulletproof, is an observability tool for AI coding agents that renders their activity as a pixel-art office in which each running agent becomes a character moving through the space. The visual conceit is doing real work: as agents complete more autonomous actions per session, the practical problem shifts from prompting to supervision, and a wall of JSONL logs is a poor supervision surface. ctrl connects to agents by watching the session files they already write — it tails the JSONL transcripts under the agent's project directory — which is why it works with anything that writes them, including Claude Code, Codex CLI, Gemini CLI, Aider, Cline, Amazon Q and Augment Code, and including those agents when run inside Cursor, Windsurf or JetBrains IDEs. Beyond the office view there is a session inspector for drilling into transcripts, tool calls and costs, showing every read, write and bash command with per-turn timing and token usage. Multi-daemon support lets one view cover parallel workstreams across several machines, which is the team case. Sharing works through an encrypted relay link or QR code so a teammate can observe without installing anything. It runs as a self-hosted local daemon started with a single npx command, needs no login, and is free.
