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.

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets
