'Second Brain' agent pitches itself as a lighter alternative to Hermes
Second Brain is an AI agent framework presented as an alternative to Hermes and OpenClaw. Its core is a written in pure Python — about 15,000 lines of code total, which is compact for a project of this scope. Every feature beyond the core (tools, database tasks, LLM backends, OCR, Telegram and Discord s) is an installable plugin, so you only add what you need.
Conversations are saved in SQL and the runtime uses a , meaning the agent can recover from crashes and even resume mid-turn. It is light enough to run on a smartphone and can be used to build websites, robots, or coding projects, according to the creator.
Key points
- design keeps the core tiny and fast to start
- All features (tools, UI, LLM backend) are optional, installable plugins
- SQL storage and allow crash recovery mid-conversation
- Light enough to run on a smartphone
- Creator claims it is significantly smaller and less bloated than Hermes or OpenClaw
