The short version

  • Each has a real cost: Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.; Autonoly pricing is credit-based, so heavy web-scraping or long-running workflows can consume the monthly allowance quickly and require add-on credit packs.
  • They diverge on capability: Windmill covers Script-to-workflow engine, Autonoly covers Natural language workflow builder.

Where each one falls short

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

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.

Autonoly

  • Pricing is credit-based, so heavy web-scraping or long-running workflows can consume the monthly allowance quickly and require add-on credit packs.
  • The free plan allows 1,000 credits and three concurrent workflows a month, which is enough to trial the product but not to run anything continuously.
  • No published mobile apps (iOS/Android); the platform is web-based only.
  • Company details such as founding date, founders, and team size are not disclosed on the site, making it harder to evaluate the vendor's track record.
  • As an AI-agent-driven scraper/executor, reliability on sites with aggressive bot protection or frequently changing layouts may vary compared to purpose-built RPA tools.

Source
Autonoly: What happens if I run out of credits?

Autonoly notifies you and suggests optimisations rather than stopping outright: you can upgrade at any time, or have non-critical workflows paused automatically until the allowance resets.

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.
