Where each one falls short

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

GNU Emacs

  • Steep learning curve for its default keybindings and Lisp-based configuration.
  • Default UI looks dated compared to modern editors without heavy customization.
  • Performance can lag on very large files compared to newer editors.
  • Discoverability of features is poor without prior familiarity or external guides.

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier
