Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Boomi
- Subscription tier prices are not published; only the pay-as-you-go base of $99 a month plus usage is stated
- Metered on several axes at once, including connections, users, environments and API transactions, so the bill is hard to predict from any one of them
- Connection counts, environments and user seats are all capped by edition
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.
