✶ Marco

build any agent you can describe

Open Studio. Tell Marco what you want to build — a research analyst that turns a topic into a memo with sources, a competitor profiler that maps a market in an afternoon, a writing editor that critiques drafts before you publish, a Socratic coding tutor that refuses to give answers, a security analyst that triages incident reports. Marco drafts the agent, shows you the diff in the right pane, you review and publish. Every change is a draft until you publish; roll back to any past version when something regresses.

Each agent runs in its own Linux sandbox — code execution, file system, web access, persistent memory, per-agent skills. The runtime is open source.
