Meet EverOS: An Open Source Markdown-First Agent Memory Runtime With Hybrid BM25 + Vector Retrieval and Self-Evolving Skills
Why it matters
Open-source agent memory infrastructure is becoming table stakes. EverOS removes the friction of rolling your own—hybrid retrieval + skill evolution could accelerate agent deployment across teams and enterprises.
Key signals
- EverOS: open-source agent memory runtime
- Architecture: Markdown-first storage indexed by SQLite + LanceDB
- Hybrid retrieval: BM25 + vector search combined
- Multimodal ingestion support
- Self-evolving Skills capability
- License: Apache 2.0
- Source: EverMind
- Includes runnable code walkthrough and interactive demo
The hook
EverMind just open-sourced the memory layer every AI agent team has been building in-house. Hybrid BM25 + vector retrieval, self-evolving skills, local-first. Apache 2.0.
EverMind has open-sourced EverOS, a local-first memory runtime that stores AI agent memory as plain Markdown indexed by SQLite and LanceDB. It combines hybrid BM25 + vector retrieval, multimodal ingestion, and self-evolving Skills under an Apache 2.0 license. Here's what it is, how the architecture works, where the benchmarks stand, and where it still falls short — plus a runnable code walkthrough and an interactive demo.
