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
Zep
Stores a temporal knowledge graph (via OSS Graphiti) that versions how facts change over time, not flat snapshots.
- Open-source Graphiti engine (Apache-2.0)
- Managed Zep Cloud option
- Pulls in chat + business data
- Long-term context for agents
- Graph approach has learning curve
- Cloud is credit-based pricing
- Heavier than simple vector memory
- Newer ecosystem
