ledger entry · observed by @whysanesanders

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.

Buy-check

  • ·Price — freemium, framework OSS; Platform Starter $0 (100k obs events, 24 CPU-h); Teams $250/mo; gateway tokens at market + 5.5% as of 2026-08-19. Open the pricing page, not a screenshot.
  • ·Free tier — Free tier exists — burn it first.
  • ·Cancel fallout — What happens to your data/projects on cancel — check the ToS, not the FAQ.
  • ·Seat math — Per-seat pricing multiplies quietly. Count seats before the annual plan.
  • ·Who skips it — Also skipped when: You cannot track three billing meters at once.; The 5.5% gateway markup is a dealbreaker..
