Open score and India fit

Our open score gives a tool up to 60 points from signals we can check: rupee pricing, GST invoice, UPI, data in India, a public price, a free plan and the number of alternatives. “Not recorded” means we have not found a vendor statement on that point, not that the answer is no. How the score is worked out.

Before you decide

  • Both in dollars. Langfuse counts “units” (traces and events); Helicone counts requests; the plans do not map one to one.
  • Prompts sent to a monitoring tool may hold customer data. Read each vendor's data location before you connect production traffic.
