clickTag and exits
Catch missing, malformed, or platform-hostile clickTag setup before the ZIP leaves your machine.
CLI-first HTML5 ad validation
Ship HTML5 ads without the QA back-and-forth.
Ad-Preflight runs locally, validates your creative, detects compliance, packaging, clickTag, asset, and performance-risk issues, and exports an upload-ready ZIP before you send it to ad-ops or the client.
Global install is best when you move between many creative folders. Use npx or a pinned dev dependency when your CI needs strict version control.

Workflow
Validate every creative before anyone else has to.
Ad-Preflight fits the way creative developers already work: terminal first, editor friendly, and ready for build pipelines when teams need repeatable checks.
1
Build one creative or a folder full of sizes.
2
Run Ad-Preflight from the terminal.
3
Fix common issues locally.
4
Export an upload-ready ZIP for handoff.
Checks
Catch the issues that usually bounce back from QA.
Creative packaging
Validate file types, asset references, ad.size metadata, and ZIP contents against common upload rules.
Local fixes
Repair common packaging problems and produce an upload-ready ZIP without sending files to a hosted service.
Pipeline signals
Use JSON output and exit codes so broken creatives fail fast in CI instead of coming back from QA.

CI/CD
Fail the build before a broken ZIP reaches the handoff.
Run the CLI in GitHub Actions, agency build scripts, or release checks. JSON output and exit codes make it easy to fail builds and surface issues in logs or pull requests.

Deeper runtime validation when the campaign needs more than static checks.
The --deep plugin brings runtime validation to the CLI: JavaScript errors, long tasks, CPU-heavy code, network behavior, and visual checks — all before the creative reaches QA.
Local by design
Deeper checks without uploading creative files.
Runs locally, like the rest of Ad-Preflight, so you can inspect more runtime behavior without a creative ever leaving your machine.
