Detect file changes, hacks, DNS hijacking, and downtime — instantly
- Know the moment a file changes.
- Detect DNS hijacking instantly.
- Get alerted when your site goes down.
- Spot hacks before your visitors do.
Diffyy monitors your live website files and alerts you the moment something changes — whether a plugin updated itself, someone edited a file on the server, or your site got compromised. It also watches your DNS, nameservers, and MX records to catch hijacking, and alerts you if your site goes down or gets defaced. Log in to your dashboard, see exactly what happened, and take action. Every event is logged so your team always knows what happened and when.
This is what you see when a file changes on your site

Add a WordPress plugin or drop a small file on your server. Takes less than five minutes.
Diffyy remembers what your files look like and tells you the moment something changes.
See what changed, decide if it's OK, and keep a clear record of every decision.

FAQs
- What does Diffyy actually do?
- Diffyy monitors the files on your live website and alerts you when something changes — a file was modified, added, or deleted. You can then accept or reject the change from your dashboard.
- Is this only for WordPress?
- No. Diffyy works with any website — WordPress, custom PHP, static sites, or anything running on shared hosting or a VPS. WordPress just happens to be where file changes are most common.
- How do I set it up?
- Either install the WordPress plugin or drop a small file on your server. Connect it to your Diffyy dashboard and you're done. Takes less than five minutes.
- Will it slow down my website?
- No. The file scanning runs in the background on a schedule. It doesn't affect your website's speed or visitor experience.
- What kind of changes does it detect?
- Any file change — plugin or theme updates, manual edits via FTP or file manager, and unauthorized modifications like malware injections or backdoors.
- Is Diffyy free?
- There's a free plan for 1 site. Paid plans cover more sites with faster checks and longer history. Exact pricing will be announced at launch — waitlist members get early-access rates.
- What is DNS monitoring?
- Diffyy watches your nameservers, IP address, and MX records. If someone hijacks your DNS — redirecting your visitors or email to a different server — you'll know immediately.
- What is email hijacking, and does Diffyy detect it?
- Email hijacking happens when an attacker changes your domain's MX records to reroute your incoming email to their server. They can then intercept password resets, invoices, client messages — anything sent to your domain. Diffyy monitors your MX records and alerts you the moment they change, so you can act before damage is done.
- Does Diffyy check if my site is down, hacked, or defaced?
- Yes. Diffyy monitors your website's availability and checks for signs of defacement — like unexpected changes to your homepage title or content. You'll get an alert the moment something looks wrong.
