LangGraph Studio adds visual debugging but core framework is free. You pay LLM API costs separately.

  • Anyone expecting a flat $19/mo SaaS subscription
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Moderate: code-first graph design and infra setup.
  2. Scale breakpoint
    LangSmith/managed hosting costs at scale; LLM bills dominate.
  3. Walled garden
    Low: OSS, self-hostable, model-agnostic.
Still a fit?
If none of these block you, start on the free plan.
