Developers ship local-first memory solutions for coding agents

According to GitHub repositories for Remembrane and Llmem, indie developers are releasing memory persistence libraries that give coding agents like Codex and Claude Code persistent knowledge across sessions without requiring vector databases or external APIs. Remembrane offers SQLite-backed storage with exact hybrid recall (vector and BM25 search), conflict detection, and time-travel journaling, while Llmem provides a persistent memory service built in Go with MCP server support.
