The short version
- Each has a real cost: Umami there is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.; Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
- They diverge on capability: Umami covers Cookie-free tracking, Windmill covers Script-to-workflow engine.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Umami
- There is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
- Self-hosting is only free in licence terms; you own the database, the upgrades, the backups and the query performance at scale, and a busy site's events table grows quickly enough to need real attention.
- Because it stores no persistent identifier, it cannot follow a user across devices or sessions in any meaningful way, which makes returning-visitor and lifetime-value questions unanswerable by design rather than by omission.
- Cloud overage is billed per event beyond the plan allowance, so a traffic spike or a badly instrumented custom event can produce a bill materially above the $20 or $200 headline before anyone notices.
- It is maintained by a small team, so the pace of new capability is modest and enterprise expectations such as SSO, granular role permissions and formal support agreements are limited compared with commercial analytics vendors.
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.

Answered from the vendors’ own pages
Umami: Is Umami really free?
Self-hosted, yes; it is MIT licensed with no event cap. You pay for the server and database. Umami Cloud has a free tier at 100,000 events a month and paid tiers from $20.
Windmill: What does Windmill cost?
Windmill's Free and Open-source edition is $0/month for self-hosted use with unlimited executions, while Enterprise starts at $120/month with unlimited workspaces and uncapped SSO seats, priced further by developer/operator seats and compute units.
SourceUmami: Do I need a cookie consent banner?
For Umami analytics specifically, generally no, because it sets no cookies and stores no personal data. Other tags on your site may still require one.
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.
SourceUmami: Can it replace Google Analytics?
For traffic, referrers and event counts, yes. For attribution modelling, audiences and advertising integration, no.
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.
SourceUmami: What does it need to run?
A container and a PostgreSQL or MySQL database. Most people deploy it on infrastructure they already pay for.
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.
