Revell vs MemPalace
MemPalace is the best open-source option if you want to run your own memory store — and it benchmarks well. The cost is the work: Python setup, ChromaDB, manual configuration, and a custom integration to let an agent call it. Revell is the turnkey path: MCP tools your agent uses immediately, compaction protection, and Guardian identity safeguards, with none of the operations.
