Every deploy, measured against your last known-good.
StageFlow runs seven scanners, compares each release against the baseline you promoted, and shows exactly what changed. Local projects work without an account and stay in your browser.
No account. Artifacts expire after 24 hours. Local projects stay in this browser.
Create a local project when you are ready to compare releases.
The baseline idea
StageFlow gives every scan a point of reference, so changes are clear and actionable.
- 92
Establish a baseline
Pick a known-good run as your point of reference.
- 88
Scan every deploy
Each new scan is compared against that baseline.
- ▼ 4
Review only what changed
New or worsened findings are highlighted; everything else stays quiet.
From URL to report
Three steps. No setup required.
Configure
Point at a URL or upload a ZIP archive.
Run
Each scanner runs in an isolated rootless container.
Ship
One merged report with severity, evidence, and remediation.
Seven scanners, one merged report
Each runs in its own rootless container and merges into a single severity-ranked report — the same shape from the CLI, from CI, or from the browser.
