From VAST URL to validated report in seconds
No configuration required. Paste a URL and get a complete audit.
Paste URL or upload XML
Drop in a VAST tag URL or paste raw XML. We handle both inline VAST and multi-level wrapper redirects — no configuration needed.
We audit everything
Wrapper chains are resolved hop by hop, XML is validated against the schema, and media files are inspected for resolution, bitrate, codec, and duration.
Review your report
A persistent, revisitable report with every finding — schema errors, warnings, media specs, and a live preview of the creative.
Everything you need to ship clean VAST
A complete audit suite for ad ops teams, publishers, and anyone managing VAST tags at scale.
Wrapper chain resolution
Follows every redirect hop until reaching the inline VAST, mapping the full chain and flagging broken or circular links.
XML schema validation
Validates document structure against VAST 2.0, 3.0, and 4.x specifications, reporting every violation with context.
Media file analysis
Inspects video codec, bitrate, resolution, and duration — surfacing compliance issues before the tag goes into rotation.
Creative preview
Plays the ad creative directly in the validator so you can confirm it renders correctly before signing off.
Persistent project reports
Every validation run is saved to your workspace. Revisit or compare reports at any time.
Errors & warnings breakdown
Every issue is categorised by severity — errors that block delivery, warnings to review, and informational findings.
