--- title: "statewave vs memsearch" type: "comparison" canonical_url: "https://www.graphcanon.com/compare/smaramwbc-statewave-vs-zilliztech-memsearch" tools: ["smaramwbc-statewave", "zilliztech-memsearch"] --- # statewave vs memsearch *GraphCanon updated Aug 22, 2026* ## Verdict Pick statewave if statewave focuses on reproducibility and provenance in memory management for AI agents, using Postgres plus pgvector for self-hosted operations rather than relying on query-time retrieval; pick memsearch if memsearch is a hybrid memory management solution for AI agents with Markdown and Milvus backing, ideal for rich semantic search and long-term data storage. [statewave](https://statewave.ai) reports 289 GitHub stars, 22 forks, and 14 open issues, last pushed Jul 30, 2026. [memsearch](https://zilliztech.github.io/memsearch/) has 2.5k stars, 231 forks, and 240 open issues, last pushed Aug 21, 2026.
