Key Insights
- Complexity spectrum: OpenClaw (80K lines comprehensive) vs ElizaOS (50K modular) vs Takopi (225 overlay) - different "build vs buy" points
- Plugin philosophy: OpenClaw (8 types + validation = max flexibility) vs Takopi (single entry = zero-config) vs ElizaOS (4 types = clean separation)
- Memory strategies: OpenClaw (sqlite-vec + session isolation = privacy) vs ElizaOS (pgvector + relationships = context) vs Takopi (stateless = delegate)
- Security: Only OpenClaw implements approval gating + sandbox + PII sanitization - others rely on allowlists without granularity
- Use case alignment: OpenClaw (personal assistant + desktop) vs Takopi (Telegram coding + minimal) vs ElizaOS (character Web3/social) - architecture follows intent
