WHAT YOU CAN VERIFY
Everything you need to test.
Multiple asset types and browser-level requests, without installing a single dependency.
MIME types
Inspect the server's Content-Type header for every asset and catch incorrect upload metadata.
Cache behavior
Review response headers such as Cache-Control, ETag, and CF-Cache-Status when provided.
LIVE BROWSER CHECK
Asset diagnostics
Check files hosted on the same origin as this page. Results reflect actual network requests from your browser.
| Asset | HTTP | Content-Type | Cache | Latency |
|---|---|---|---|---|
| Click “Run checks” to test your deployment. | ||||
HEAD requests may be blocked by some configurations; the checker falls back to GET. Cache headers may be missing on an R2 development URL. Reload to inspect browser caching separately.
QUICK START
Deploy in three steps.
01
Create a bucket
Create an R2 bucket in Cloudflare and upload index.html plus the assets/ directory, preserving paths.
02
Expose your files
Enable a public development URL for testing, or attach a custom domain in your R2 bucket settings.
03
Open and validate
Visit https://YOUR-R2-HOST/index.html, run diagnostics, and inspect response headers in DevTools.
Important: R2 public buckets serve objects; they do not automatically provide full static-site routing. The root path
/ might not resolve to /index.html without a Worker or equivalent routing layer.
