Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | claude-mem | mem0 |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Related files & memory | ●●●●● User/session only |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Configurable filters | ●●●●● Multi-signal retrieval |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Config file & modes | ●●●●● Plugins & config |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Self-hostable (local worker) | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Bring-your-key (many providers) | ●●●●● Multiple LLMs |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command install | ●●●●● One-command start |
Which one to pick
Pick claude-mem if…
Easy setup — one-command installer and a local worker that preserves and injects compressed session context into future Claude Code sessions.
- Context depth: Related files & memory (3/5 against 1/5)
- Model freedom: Bring-your-key (many providers) (5/5 against 3/5)
Pick mem0 if…
Self-hostable — one-command bootstrap and SDKs let teams add a scalable, token-efficient memory layer while keeping data under their control.

- [plan-14] Child Process Ownership — every process the worker spawns dies with the worker 👍 3
- SyncHub projector stalled: projected_seq stays "0" while head_seq reaches "40", so no push can ever validate 👍 2
- Cloud sync permanently stuck: SyncHub push response violates head_seq <= projected_seq invariant 👍 2
