¹ Builds are compiled using GitHub Actions workflow minutes. While xllify is free during beta, GitHub Actions usage may incur charges depending on your GitHub plan. Free GitHub accounts include generous monthly minutes suitable for most teams.

² AI coding assistance requires access to Claude, paid for directly with Anthropic. AI can make mistakes - please verify all generated code before use.

³ Individual plan builds expire on February 1st 2026 during the beta period to ensure users receive the latest updates and fixes. After beta, Individual will become a free plan with non-expiring builds. The standard library will be extended throughout beta. Some beta features may change before general availability.

⁴ You will need to provision or purchase your own code signing certificate.
