If you’ve used a coding agent, you know the pain. You’re deep into a feature and everything is clicking. Then the context window fills up, it compacts, and key details are lost.
Mastra Code is different. Powered by our state-of-the-art observational memory, it watches, reflects, and compresses context without losing important details.
The result: long-running coding sessions that stay precise, letting you build faster, merge sooner, and ship more.
Mastra CodeThe AI coding agent that never compacts
Observational Memory is a SoTA memory system for AI agents - scoring 95% on LongMemEval, the highest ever recorded. It works like human memory: two background agents act as your agent's subconscious, one observing and compressing conversations, the other reflecting and reorganizing long-term memory. It extracts what matters and lets the rest fade - just like you do. Available in Mastra today - with adapters for LangChain, Vercel AI SDK, OpenCode and others coming soon.
