Pricing & Fees

  • Pricing: The Pydantic pricing page describes a Personal plan that is free forever and a Team plan at $49/month, both including $20 of monthly usage (10 million records); additional records cost $2 per million on Team and Growth.
  • Free tier: The Personal plan includes 10M telemetry records per month hard-capped at $0, no credit card required, with 3 projects, 30-day retention, 1 seat and 2 read-only guests.
  • Usage limits: On the Personal tier, ingestion pauses once the 10M record limit is reached, so no overage charges can accrue; Team users can set a hard price cap to lock in their bill.
  • Seats & fees: The Team plan includes 5 seats and 10 read-only guests; the AI Gateway supports BYOK for up to 3 provider credentials with no markup, while built-in providers carry a 5% markup fee.
