The short version

  • Only RudderStack has a free tier, so it costs nothing to try first.
  • Each has a real cost: Relevance AI pricing is per task rather than per seat, with the vendor's own published example showing a customer running 1.24 million tasks a month for $11,800, and individual agent runs ranging $0.01 to $0.11 depending on the model, as of August 2026.; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Relevance AI

  • Pricing is per task rather than per seat, with the vendor's own published example showing a customer running 1.24 million tasks a month for $11,800, and individual agent runs ranging $0.01 to $0.11 depending on the model, as of August 2026.

RudderStack

  • On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • The free plan allows 250,000 events a month
  • Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
  • Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
