MiMo Code
A coding agent with explicit long-term memory architecture
MiMo Code is an open-source terminal AI coding agent built on OpenCode. Optimized for long-horizon tasks, it uses an independent checkpoint subagent to manage unbounded context windows, executes sandbox workflows, and evolves via scheduled maintenance.
MiMo Code is based on @opencode, but puts more effort into handling long-running sessions.
Instead of letting the main agent manage its own memory, it uses a separate writer subagent that periodically writes structured checkpoints on a schedule.
A key design choice is that these checkpoints are triggered relatively early, well before the context window fills up. This avoids having to do heavy compression under high context pressure.
When the window eventually approaches its limit, the system rebuilds the working context from the accumulated checkpoints and project memory, rather than relying on increasingly unreliable summarization.
It also runs background processes to extract reusable patterns from past work over time.

Who hunted MiMo Code?
MiMo Code was hunted by Zac Zuo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hi everyone!
MiMo Code is based on @opencode, but puts more effort into handling long-running sessions.
