MiMoCode: An Open-Source AI Coding Agent with Cross-Session Memory

Overview

MiMoCode is a terminal-native AI coding assistant designed to read and write code, execute commands, manage Git repositories, and maintain a persistent memory system. This system ensures a deep understanding of the project across multiple sessions while continuously improving itself. Built as a fork of OpenCode, MiMoCode offers a robust environment for developers seeking an autonomous coding partner.

Benefits

MiMoCode offers several key advantages for developers. Its multi-agent system allows users to switch between different modes like build, plan, and compose using the Tab key. Each agent serves a specific purpose, from full development tasks to read-only analysis. A standout feature is its cross-session memory powered by SQLite FTS5 full-text search. This ensures the agent retains project context without needing to relearn it in every session. The memory system includes project memory, session checkpoints, scratch notes, and task progress logs. Intelligent context management strategies handle large projects by automatically saving session state and rebuilding context when limits are reached. The task tracking system uses a tree-shaped structure that integrates with the checkpoint system to preserve progress. Users can also set stopping conditions for sessions, and an independent judge model evaluates if the task is truly complete to prevent premature stops. Voice input is available for logged-in users, allowing real-time streaming audio transcription. The dream and distill commands help manage knowledge by extracting persistent information and packaging repeated workflows into reusable skills.

Use Cases

MiMoCode is ideal for developers who want an autonomous coding partner in their terminal. It can be used for various development tasks, from writing and editing code to managing Git repositories. The build agent is perfect for full development tasks, while the plan agent is great for code exploration and solution design. The compose mode is designed for specs-driven development and skill-driven workflows. Developers can use the tool to track task progress seamlessly across multiple sessions. The voice input feature is useful for hands-free coding sessions. The dream and distill commands are beneficial for knowledge management and creating reusable skills from repeated workflows. MiMoCode is suitable for both individual developers and teams looking to streamline their development process with AI assistance.

Pricing

MiMoCode offers a free-for-limited-time anonymous channel called MiMo Auto that requires zero configuration. For users who want to use the Xiaomi MiMo Platform, OAuth login is required. The tool also supports importing existing authentication from Claude Code in a single step. Advanced users can add any OpenAI-compatible API via the Text User Interface for custom provider support.

Vibes

MiMoCode represents a significant advancement in AI-assisted coding, offering a terminal-native experience that combines autonomous capabilities with robust memory and context management. By leveraging multiple agents, persistent memory, and intelligent context handling, MiMoCode aims to streamline the development process and enhance productivity for developers worldwide. The tool has received positive feedback for its innovative approach to maintaining project context across sessions and its ability to handle complex development tasks autonomously.

Additional Information

MiMoCode is an open-source project built as a fork of OpenCode. It is available for installation via one-line install scripts or npm. The development environment can be set up using Bun for those interested in contributing or running the tool locally. The project includes configuration options for provider and model selection, agent permissions, checkpoint and memory behavior settings, and more. Advanced users can enable Max Mode for parallel best-of-N reasoning with judge selection by setting experimental.maxMode in the configuration file.
