Features Comparison
Nivoli Edge
-
Full-Page Edge Caching
Caches whole pages on the Cloudflare node nearest each visitor, tagged with Surrogate-Keys so one post save purges only the affected pages via stale-while-revalidate.
-
Asset URL Versioning
Gives stylesheets, scripts and fonts addresses that change on purge, so browsers pick up updated files immediately instead of serving stale ones for up to a week.
-
Edge Image Optimization
Rewrites images at the WordPress filter boundary and transforms them on the fly via Cloudflare Image Resizing: right-sized per device, WebP or AVIF per browser.
-
Origin Shield
When the origin errors or stops responding, serves the last good cached copy for up to 7 days, with email alerts when the shield engages and when the server recovers.
-
Pre-PHP Security Shields
Seven shields enforced at the edge before WordPress boots: stray-.php 404s, wp-admin IP lock, login rate limiting, AI-crawler blocking, login country lock, XML-RPC 410, security headers pack.
-
Cookieless Audience Analytics
Measures pageviews, countries, referrers and devices at the edge, no JavaScript snippet, no cookies and no consent banner; bots counted separately.
-
Edge URL Rules
Answers dead routes with cached 410s and maps redirects from the edge with per-rule fired counts; one-click block from the error log.
-
Surgical Purge
Dispatches purge requests non-blocking by Surrogate-Key tags on save, delete and comment events; purge triggers can be locked to your own IPs.
-
Coverage Audit & Repair
Weekly re-run measures the optimized share and emails on regression; the runtime misses log groups uncovered images into one-click rules; fake-image scan repairs HTML-disguised-as-JPG files.
-
Broken & Heavy Image Tools
404 inbox from real edge failures, where-used lookups with edit links, a heaviest-images list with one-click Tinify shrink, and a scan for images that never load.
