Where each one falls short

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

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

Metasploit

  • The free Framework edition is command line only; the web interface is Pro only
  • Automated exploitation, automated credential attacks and antivirus evading dynamic payloads are restricted to Metasploit Pro
  • Reporting, audit wizards, task chains and closed loop vulnerability validation are Pro only
  • Rapid7 publishes no price for Metasploit Pro and routes buyers to contact sales
