The short version

  • Only Windmill has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cyclr entry pricing of 1,595 US dollars a month for one connector and 100,000 API calls means small vendors will find building two or three integrations in-house genuinely cheaper, and Cyclr only pays off past a certain integration count.; Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
  • They diverge on capability: Cyclr covers White-label integration UI, Windmill covers Script-to-workflow engine.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Cyclr

  • Entry pricing of 1,595 US dollars a month for one connector and 100,000 API calls means small vendors will find building two or three integrations in-house genuinely cheaper, and Cyclr only pays off past a certain integration count.
  • Connectors and API calls are metered separately, so a successful integration marketplace pushes you up tiers as your customers adopt it, meaning the cost rises with usage rather than with the revenue that usage generates.
  • Custom connectors to APIs outside the library are your work to build and maintain, so the promise of not building integrations only holds for applications Cyclr already covers.
  • Debugging is harder when the integration runs in a third-party runtime, because your support team sees a failed workflow rather than an HTTP response and has to escalate to Cyclr for anything non-obvious.
  • Deep embedding creates real switching cost: your customers' live integrations run on Cyclr, so migrating later means recreating every customer workflow, which in practice means you rarely leave.

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.

Cyclr: Do my customers know they are using Cyclr?

No. The interface is white-labelled to appear as part of your product.

Windmill: Is there a free plan and what are its limits?

The free self-hosted plan supports unlimited executions but caps SSO at 10 users, workspaces at 3, groups/permissions at 4, and email triggers at 100 per day.

Source
Cyclr: Can I host it in the EU or UK?

Yes, on the private cloud tiers, which matters for European procurement requirements.

Windmill: How is usage metered on Windmill Enterprise?

Enterprise usage is metered through seats (developer seats at $20/month, operator seats at $10/month) and compute units, e.g. $100/month for 2 standard-worker compute units.

Source
Cyclr: What if the connector I need does not exist?

You build a custom connector using Cyclr tooling, which is work you own rather than work the platform removes.

Windmill: What happens to a self-hosted Windmill deployment if the company shuts down?

The pricing page addresses this directly as an FAQ topic, noting that self-hosted applications built on the open-source edition can continue running independently of Windmill the company.
