Where each one falls short

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.

Proton Mail

  • Paid plan pricing not displayed on vendor site
  • Free tier limited to 1 GB storage
  • Free tier limited to single email address
