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

Resemble AI

  • The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
  • Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.
  • SSO and org-wide security features are only available starting on the $1,000/month Business plan.
  • Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.
