- Administration console is dense
- Upgrades need care
Neovim: pros & cons

Our verdict on Keycloak
The serious open-source answer to Auth0. Budget for the operations, because the licence saving is not free.
Our verdict on Neovim
Superb once configured, and configuring it is the cost. Do not adopt it during a deadline.
