What is Flagger?
Infrastructure automation tool for Kubernetes that manages staged application releases using canary deployments, A/B testing, or blue-green strategies. It progressively shifts traffic to new versions while monitoring system health and running conformance tests to minimize production risk.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Flagger, not the verdict.
