A TS-native LangGraph-shaped kit with evals and a real price page for the hosted control plane. Starter is $0 plus overage; Teams is $250. Gateway markup is 5.5% on tokens. Persistent 24/7 servers are $100/project extra. Framework ≠ platform bill.
Strengths
- TypeScript-native agent framework with evals built in.
- Hosted control plane has a real, published price page.
- Starter tier is $0 and self-host is available.
Known limitations
- Hosted CPU, events, and tokens are three meters; a chatty agent trips all three.
- 5.5% gateway markup on top of provider rates if you use their gateway.
- Persistent servers are a $100/project add-on, not included in Starter.
- Self-host still needs you to run evals, tracing storage, and secrets.
Use it when
- TypeScript teams building agents that need observability.
- Teams that want a LangGraph-shaped kit without the Python stack.
Skip it when
- You cannot track three billing meters at once.
- The 5.5% gateway markup is a dealbreaker.
- Persistent 24/7 servers are needed but the $100 add-on is too much.
