The short version

  • Only Census has a free tier, so it costs nothing to try first.
  • Each has a real cost: Census census was folded into Fivetran Activations, per the vendor: "Previously, this was called a sync in Census", and its own pricing page redirects to Fivetran pricing rather than showing Census plans; 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.
