What is the logic behind Windmill's pricing?

Windmill offers a free and open-source tier with unlimited executions and up to 50 users, alongside an Enterprise tier for advanced needs in observability, security, and performance, with pricing based on developers, operators, and compute units.

An operator is a user who can only execute scripts, flows, and apps, but cannot create or edit them. Operators are typically half the price of developers in the Enterprise plan.

What are compute units?

Compute Units (CU) are a measure of the computing resources used by Windmill workers. They are used in the Enterprise pricing model to simulate the cost based on standard, native, and agent workers.

Is Windmill billed based on usage?

Windmill's Enterprise plan has components that are usage-based, such as the number of developers, operators, and compute units. The Free and Open-source plan offers unlimited executions.

What is Windmill's security level on cloud?

Windmill Labs is SOC 2 Type II compliant, ensuring a high level of security for its cloud offerings. Enterprise features include granular RBAC, SSO, Secret Management, and comprehensive Audit Logs.
