Choose Keycloak if:
Organisations that need enterprise identity without a per-user bill.
Choose Visual Studio Code if:
Almost any developer, from first project to large codebase.
Keycloak: pros & cons
- Full identity server at no licence cost
- Standards support including SAML and OIDC
- Complete control over user data
- Operating it is a real responsibility
- Administration console is dense
- Upgrades need care
Visual Studio Code: pros & cons
- Free with no paid tier to upsell you
- Extension for practically every language and tool
- Remote and container development built in
- Heavy on memory once extensions pile up
- Extension quality is inconsistent
- Telemetry in the Microsoft build concerns some teams
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 Visual Studio Code
The safe default. If it feels slow, the cause is usually your extensions rather than the editor.
