Stars on GitHub
Local-first memory for Claude Code. It stores conversations verbatim in a private palace you can search before answering about past work, people, projects, or decisions, with optional shared-brain hub setup.
@mempalaceGives Claude Code a private memory that stays on your machine. It stores past conversations word for word, so you can ask what was decided, what happened before, or who was involved and get the original context back. It can also hand tasks to other agents.
@milla-jovovichKeeps large tool outputs, logs, and files out of Claude Code's context window by processing them in a sandbox and indexing them for focused search. Includes diagnostics and a knowledge base indexer.
@mksgluGives coding agents a git-backed wiki for long-term project memory, with skills for retrieval, durable notes, session handoffs between agents, cross-project messaging, and memory consolidation.
@akitaonrailsA coding agent harness whose agents keep memory and identity across sessions, so they learn and improve over time. You can run it in a terminal, in the browser, or through Telegram, Slack and Discord.
@letta-aiA background agent for Claude Code that watches your sessions and reads your files, builds up memory over time, and offers guidance back during your work.
@letta-aiAudits a Claude Code or Codex setup for context-window waste, fixes it with the user's approval, and measures the savings. It also tracks costs, helps resume prior sessions, and offers a usage dashboard.
@alexgreenshA self-learning system for Claude Code that captures your corrections during sessions and reminds you to run /reflect to save them to CLAUDE.md as permanent memory. It also discovers recurring workflow patterns.
