Muse Code exits beta with SDK, sub-agent workflows and monthly subscription
On September 1, Alexandr Wang announced that Muse Code has ended its beta and officially launched, with a monthly subscription and a developer preview SDK rolling out alongside.
Confirmed
- Muse Code is out of beta and officially released; developers can install it quickly with a single curl command
- A developer preview SDK is live, allowing users to build custom Agents on top of it
- New features include messaging between sessions, workflows for orchestrating teams of subagents, and session rewind
- A monthly subscription plan is available, starting at $5
- Muse Code is positioned as an Agent framework for complex work, supporting Agents sharing context across different sessions
Why it matters
- Opening up the SDK signals Muse Code evolving from a finished tool into a programmable Agent platform, letting developers embed its capabilities into their own Agent systems
- Subagent orchestration and cross-session context sharing target multi-Agent collaboration on long-horizon complex tasks — the core increment of this release
- The subscription model marks the product's business model taking shape, and the $5 entry price is friendly to individual developers
