Motorhead
Early Rust memory server from Metal: sliding window of messages with incremental summaries and Redis-backed long-term search.
README: 'Motorhead (DEPRECATED) — Support is no longer maintained.' Last release v3.0.2 2023-12-19; last commit 2025-06-10 (dependabot). (checked 2026-10-25)
In Agent memory
Where it stands apart
- Is it actively maintained? dormant, sunsetting, or archived (14% of 21 others)
- In the default setup, who mainly decides what gets remembered? the app or user, by saving each memory explicitly (5% of 21 others)
- Does it work with models from different LLM vendors? no, tied to one model vendor (10% of 21 others)
- What is the main storage model for long-term memory? vector store of extracted facts or chunks (20% of 20 others)
What it shares with most of the community
- How is the main thing licensed? permissive open source (MIT/Apache/BSD) (67% of 21 others)
- How is it mainly sustained? company with a paid product, tier, or ads (75% of 20 others)
- Can it run entirely on your own device or infrastructure, without the maker's servers? yes (67% of 21 others)
- Who is it for? developers (76% of 21 others)
- How can the person the memories are about see and edit them? only through developer APIs or a developer dashboard (62% of 21 others)
- By default, how do old or wrong memories mainly go away? the system updates, merges, or decays them automatically (58% of 19 others)
- How is memory separated between users or tenants? built-in scoping by user, agent, session, or tenant IDs (62% of 21 others)
