claude-mem: cross-session persistent memory plugin for coding agents
claude-mem is an open-source persistent memory plugin that captures an agent's tool-use observations during sessions, compresses them into semantic summaries with AI, and injects relevant context into later sessions; it advertises support for Claude Code, OpenClaw, Codex, Gemini, Copilot, OpenCode and more. It installs with a single npx command, stores data in a local SQLite database with Chroma-based hybrid semantic and keyword search, and lets users bring their own OpenRouter or Gemini key, fall back to an Anthropic plan, or subscribe to its hosted memory service (the project claims a 30-day free trial). The repository appeared on GitHub Trending; the usage-gain and trial claims come from the project's own README and are not independently verified.
Cross-session memory is becoming a core component of coding agents, and open-source plugins like this reflect developer demand for local control over how context is retained.
