Run a package review

Upload a banner package below to review likely trafficability, bundle health, and anything that should be checked before handoff.

Uploads are handled as untrusted files. We apply region, size, and archive safety checks before validation, and this tool does not keep an account history of your uploads.

Recommended for launch review: keep uploads limited to the working banner package only, and avoid including unrelated source files or sensitive client documents.

Step 3

Run the validator

Start the review to generate trafficability guidance and a structured results report.

We’ll inspect the package, estimate likely trafficability, and surface blockers, review points, and softer advisories in a structured dashboard.
