Palace Memory
Persistent memory for AI coding agents that recalls decisions across every session.
What is Palace Memory?
AI coding agents excel at individual tasks yet lose all context the moment a session closes. Palace Memory solves this by storing decisions and conventions in a local or team-hosted database, automatically feeding relevant details back to the agent on demand. Agents no longer restart from zero or require repeated explanations of architecture and past fixes. The system installs as a lightweight Rust binary and connects through the standard MCP interface used by Cursor, Claude Code, and Codex. Solo users run it free on their machine while teams deploy a central server that keeps all memory within their own infrastructure. Shared workspaces, knowledge graphs, and audit logs let every teammate benefit from work already completed by others. Hybrid search combines keyword and vector retrieval to surface the exact source of each recalled fact. Fine-grained permissions, offline license checks, and Prometheus metrics give organizations the control and visibility required for production use.

AI models Palace Memory uses
What you can use Palace Memory for
Persistent Context for Solo Developers
Solo developers install the open-source palace-rs engine locally to give their AI coding agents lasting memory of project decisions, fixes, and conventions across multiple sessions in tools like Cursor or Claude Code.
Team-Wide Shared Knowledge
Engineering teams deploy Palace Server on their own infrastructure so that memory written by one developer's agent becomes available to teammates' agents while keeping all data within the organization's network.
Seamless Tool Switching
Developers move between Cursor, Claude Code, and Codex without losing project history because Palace supplies the same searchable memory layer to any MCP-compatible agent.
How to use Palace Memory
- 1Install palace-rs with a single command on your machine
- 2Wire the memory engine into Cursor, Claude Code, or Codex over MCP
- 3Begin coding sessions so decisions and fixes are automatically stored
- 4Deploy Palace Server via Docker or binary for team-wide access
- 5Connect additional developers to the shared server with a license key

Editor's verdict
Pros
- +Fully self-hosted and privacy-focused, data stays on your infra
- +Free forever for solo developers with seamless agent integration
Cons
- –Requires self-hosting and infrastructure setup
- –Primarily targeted at specific coding agents via MCP
Our take: Palace Memory is a solid coding & dev choice. It's valued for fully self-hosted and privacy-focused, data stays on your infra and free forever for solo developers with seamless agent integration. The main trade-off is requires self-hosting and infrastructure setup. A good pick if you want capable AI without a high upfront cost.
Frequently asked questions
Palace is a self-hosted memory layer that gives persistent, searchable recall to AI coding agents so they remember past decisions, fixes, and conventions instead of starting from zero each session.
