Updated
Claude-Mem
Gives coding agents memory across sessions by capturing what they do, compressing it and feeding the relevant context back in later.
Added
Deer Flow
ByteDance's open-source long-horizon agent harness that researches, codes and creates using sandboxes, memory and sub-agents.
Added
Oh My OpenAgent (OmO)
Agent harness add-on (OmO) for OpenCode and Pi that runs multi-model coding agent teams with memory, planning and parallel workflows.
Added
Codebase Memory MCP
MCP server that indexes codebases into a persistent knowledge graph so coding agents can look up structure quickly.
Added
Context Mode
Context window optimizer for coding agents that sandboxes tool output and persists session memory.
Added
AgentMemory
Persistent memory layer for AI coding agents.
Added
TencentDB-Agent-Memory
Team-level memory hub that turns conversations, docs and code into shared memory for agents.
Added
Beads
Issue-tracking memory for coding agents so they can keep track of long-running work.
Added
MiMo Code
Xiaomi's terminal coding agent with persistent project memory across sessions; works with any major model provider and is tuned for Xiaomi's MiMo models.
Added
ai-memory
Fabio Akita's open-source long-term memory layer for coding agents: one Rust binary that keeps plain-markdown project memory and typed handoffs shared across 20+ harnesses such as Claude Code, Codex, Cursor and Gemini CLI, so you can switch agents, machines or teammates without re-explaining the project.
Added
LazyCodex
Agent harness for Codex that adds project memory, planning, execution and verified completion for complex codebases.
Added
Compozy
Operating system for AI agents that turns Claude Code, Codex, Gemini CLI and Cursor into a team with task handoff, loops, jobs and shared memory.
Added
Zeroboot
VM sandboxes for running agent code that start in under a millisecond by forking a warm snapshot with copy-on-write memory.
Added
Beacon
An open-source memory layer that captures traces from coding agents across harnesses and turns them into self-improving memory and visibility into what your agents did.
Added
agent-qa (Vostride)
A self-improving AI QA agent with persistent memory that tests web, Android and iOS apps from plain-English test steps, for developers and coding agents.
Added
projectmem
A local-first memory layer for coding agents that records issues, attempts, fixes and decisions and warns your agent before it repeats a past mistake.
Added
Sno Station
Sno Station turns the coding agents you already use (Claude Code, Codex, Cursor, Hermes, OpenClaw) into one squad on your machine with shared memory, and its Self Learning reviews their sessions and proposes skill-file fixes you approve.
Added
Graphicle
Graphicle, from KarLex AI, is a single local Rust program that gives Claude Code, Cursor, Codex and other MCP agents a code graph and memory, returning excerpts with file and line references from your code, docs and past sessions, with no account or telemetry.
Added
Dodaios
Open-source desktop agent OS for Windows, macOS and Linux (formerly Personal Jarvis): talk to it and it runs your coding CLIs side by side, your browser and your apps, with offline Whisper speech, a local wiki memory and support for Ollama, Claude or ChatGPT subscriptions.
Added
Anchor Action Index
Shared memory of web workflows for Anchor's cloud browsers: computer-use agents replay proven paths as deterministic code and the model only steps in where a page has changed, exposed as tools on Anchor's MCP server and REST API.
Added
Dosu
Knowledge infrastructure that keeps docs, specs and agent memory current with your code for teams and coding agents.
