Where each one falls short

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

Coder

  • Premium plan pricing is not published and requires contacting sales.
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs.
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs
