Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bun

  • Linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported
  • Native Node.js addons not supported directly; requires FFI workarounds for C libraries
  • Ecosystem less mature than Node.js; fewer third-party packages optimised for Bun
  • Windows support newer and less mature than Linux/macOS; occasional edge cases

SonarQube Cloud

  • Free tier limited to 50k lines of code for private projects.
  • Base Team pricing only covers up to 100,000 lines of code before extra charges apply.
  • Enterprise-grade compliance features require a custom-quoted Enterprise plan.
  • Primarily analysis-focused; lacks the runtime and cloud-workload protection of full CNAPP platforms.
