The honest brief
ByteRover
Purpose-built for coding agents: hierarchical knowledge trees and a local-first CLI that syncs context across IDEs and assistants.
- Local-first, no telemetry by default
- Works across Cursor/Claude Code/Windsurf
- Source-available CLI (Elastic 2.0)
- Free-forever tier
- Source-available, not OSI open source
- Younger than general-purpose memory APIs
- Cloud sync and team sharing are paid
mem0
Fastest path to agent memory — extracts distilled facts with a tiny token footprint and the biggest community.
- Quick to adopt, broad framework integrations
- Stores distilled facts, small footprint
- Vector + graph + key-value storage
- Open-source with usable free tier
- Weaker on temporal/state-change queries
- LLM call on every write adds latency
- Test deletion/conflict handling for regulated use
- More library than full memory server
