Organisations that need enterprise identity without a per-user bill.
Codecov: pros & cons
- Coverage visible where review happens
- Can block merges on coverage loss
- Supports most languages and CI systems
- Coverage percentage is a weak proxy for quality
- Configuration takes tuning
- Free tier limited for private repos
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
Our verdict on Codecov
Useful as a trend signal. Chasing a coverage number instead of writing good tests is the classic misuse.
Our verdict on Keycloak
The serious open-source answer to Auth0. Budget for the operations, because the licence saving is not free.
