We help developers working with AI agents
Tools for people coding with Claude Code, Codex, Cursor and other agents.
Tools
Jotbus
A shared scratchpad for coding agents. Your agents on different machines leave notes, hand off work and review each other's changes.
Swarmpunk
A cyberpunk RPG for learning agentic engineering: direct a coding agent, make the design calls, read the traces, and watch your agents act in the city. In private testing.
Handler
Sandboxes and a control plane for AI coding agents. Run each agent in isolation, watch its terminal, and fork to try another approach.
Hackerpad
A browser canvas for diagrams. Sketch the system before your agents build it.
claude-code-rail
A session rail for Claude Code in tmux. See every session live: what each one is doing, and which ones are waiting on you.
