The short version

  • Each has a real cost: Corteza planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.; Windmill free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
  • They diverge on capability: Corteza covers Corteza Low Code, 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.

Corteza

  • Planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.
  • No pricing is published for Planet Crusts support, hosting or implementation services, so the true running cost of a supported deployment cannot be estimated without a sales conversation.
  • The connector ecosystem is small compared with commercial low-code platforms, so integrations with common SaaS tools usually mean writing against the REST API rather than installing something.
  • Hiring is hard: almost nobody has Corteza on a CV, so you are training internal developers on a niche platform and you cannot easily replace them.
  • The bundled CRM is a starting point rather than a mature product, and teams that expect Salesforce-equivalent sales functionality out of the box will spend months building the gap themselves.

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

Corteza: Is Corteza the same thing as Crust?

Yes. The project was branded Crust and renamed Corteza in 2019 when Crust Technology donated it to the Commons Conservancy.

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.

Source
Corteza: Who owns the code?

The Commons Conservancy, a Dutch foundation. Planet Crust in Cork is the primary developer and sells commercial services around it.

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
Corteza: Is there a paid enterprise edition?

No. Corteza is Apache 2.0 with no feature gating. Planet Crust sells support, hosting and development instead of a restricted edition.

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
Corteza: Can it genuinely replace Salesforce?

For case management and a straightforward sales pipeline on a self-hosted footprint, yes. For a large sales organisation relying on AppExchange products and a mature ecosystem, no.

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.
