Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Free and open source under MIT
- Small core that's extended rather than configured
- Works with most major providers, plus local models
- Embeddable through the TypeScript SDK and RPC
Cons
- No sub-agents or plan mode by design
- No built-in permission system, so isolation means running in a container
- Behavior depends on the extensions and skills you assemble
Pros
- Paid plans start at $3 a month
- Unlimited autocomplete on every plan
- SOLO mode included at every tier
- Concurrent cloud tasks scale from 2 to 20 by plan
Cons
- Usage is sold as dollar amounts, so it's hard to tell how many tasks a plan covers
- Trae's site doesn't name the models behind each plan
- Enterprise plans go through BytePlus rather than Trae directly
