The short version

  • Each has a real cost: Hevo Data billed on events ingested rather than on connectors or seats, so the bill tracks how chatty the sources are; Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
  • They diverge on capability: Hevo Data covers No-code pipeline builder, Windmill covers Script-to-workflow engine.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Hevo Data

  • Billed on events ingested rather than on connectors or seats, so the bill tracks how chatty the sources are
  • The free plan allows 1M events a month and the Starter plan starts at $265 a month billed annually
  • Event volume is a priced tier inside each plan, at 5M, 20M or 50M on Starter
  • Usage above the plan quota is charged as on demand on top of the subscription, and the overage rate is not published anywhere on the pricing page
  • Paying monthly rather than annually raises Starter from $265 to $299

Windmill

  • Free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
  • Compute unit and seat-based pricing (developer vs. operator seats, worker compute units) adds pricing complexity beyond a flat monthly fee.
  • Email triggers are capped at 100/day on the free tier, limiting event-driven use cases without upgrading.
  • Smaller ecosystem of pre-built integrations compared to more established automation tools like n8n.
