What is Magnitude?
Magnitude is an open source coding agent built from the ground up around subagents. You chat with the lead agent and it coordinates specialized subagents — explorers, planners, builders, reviewers, debuggers, and a browser agent — on your behalf.
Why Magnitude?
- Building happens in subagents, so the lead stays focused on you
- Subagents are long-lived and resumable, not disposable
- The lead can redirect subagents mid-task without starting over
- Subagents are spun up in parallel for faster work
- A shared workspace keeps handoffs between agents lossless
- Mix and match models by role to balance intelligence and speed
