Nanobot
Nanobot is an ultra-lightweight open-source AI agent written in approximately 4,000 lines of Python, compared to OpenClaw's 430,000+ lines. It provides persistent memory, web search, background sub-agents, and Telegram and WhatsApp integrations. Designed for auditability and low-resource deployment, it runs on hardware as small as a Raspberry Pi at 191MB memory.
Key Features:
- ✓4,000 lines of Python: fully auditable in a single afternoon
- ✓Persistent memory and knowledge graph for habit learning
- ✓Telegram and WhatsApp integrations
- ✓Background sub-agents for parallel task execution
- ✓Local LLM support via Ollama (no API costs)
- ✓Runs on Raspberry Pi and low-resource hardware
Pricing:
Free (MIT license) + AI API costs
Pros:
- + Codebase is 99% smaller than OpenClaw: trivial to audit for security
- + Raspberry Pi compatible: no VPS required
- + MIT license: same permissive terms as OpenClaw
- + No AI API cost when using local Ollama models
Cons:
- - Far fewer integrations than OpenClaw's 700+ ClawdHub skills
- - Smaller community: fewer tutorials and skill templates
- - Less mature codebase: fewer production deployments documented
Best For:
Developers who want an OpenClaw-style personal automation agent with a codebase small enough to audit completely, or those deploying on Raspberry Pi or low-resource hardware without a full VPS
