The difference: 100% private & local.
Online portals force you to upload assets and only catch issues after handoff. Ad-Preflight runs fully locally before anything leaves your machine.
Online validators / QA portals
- ✕Typically upload creatives to their servers - NDA and privacy risk
- ✕Often catch issues only after handoff - then the back-and-forth starts
- ✕Usually a web UI, one file at a time - rarely a CI hook
- ✕Many are static-only - can miss runtime rejections

Standard Audit
What gets checked locally
The standard audit runs in seconds whenever you package or validate a directory.
Packaging
File types, asset refs, ad.size, and ZIP size vs 150KB / 600KB / 5MB budgets - validated to spec.
Auto-fix
Repairs common issues and writes an upload-ready ZIP - your original files are backed up first.
CI signals
JSON + exit codes fail the build before handoff, not after.
Also in the free CLI - €0
Live browser preview
Serve any creative locally and preview it live in your browser, straight from the CLI - no upload.
MCP server for Cursor & AI agents
A built-in Model Context Protocol server lets Cursor and other AI agents validate and package for you.
Auto-fix with backups
Every auto-fix backs up your original files first, then writes the upload-ready ZIP.
CI/CD output
JSON results and non-zero exit codes fail the build in GitHub Actions, GitLab CI, or any script.
Plugin capabilities
Advanced checks: Deep Audit Pro
Execute creatives in a headless browser sandbox locally to run dynamic checks and inspect runtime behavior.
Heavy Ad Compliance
Flag browser-level unloads before they happen. Audit CPU, memory, and load payload sizes inside a throttled sandbox.
JS Runtime Diagnostics
Catch blank ads and slot crashes before publishing. Reports the script file, line, and column of execution errors where available.
Network Auditing
Scan for mixed content (insecure http:// assets) and identify size-budget leaks or slow connections using network waterfalls.
Render Proofing
Automate visual QA checks: generates per-size screenshots, uncovers overflow scrollbars, flags blank renders, and warns on a missing border over a white background.
Interactive Triggers
Verifies the 30-second animation limit, flags automatic page redirects, and catches popups that open without a user click.
Private Audit Sandbox
Creatives are never uploaded. The audit runs in a local headless browser on your machine - only your license token is verified online.
