Datify VS IsSiteSafe

IsSiteSafe's answer:

Most security checkers report a status and assume you already know the vocabulary. IsSiteSafe explains consequences: instead of "Content-Security- Policy: missing" it tells you that its absence is what lets an attacker run their own code on your pages. It also covers eight different questions in one place - site configuration, suspicious links, spoofed email, browser privacy - rather than one.

IsSiteSafe's answer:

No account, no rate limits, and no paid tier holding back results. Every tool is complete and free.

Where a check can run entirely in your browser, it does. File checksums, hash identification, QR decoding and the fingerprint test never transmit anything - the file or code you drop in does not leave your device. The tools that genuinely need a server, such as header scanning and certificate checks, say so plainly on the page instead of claiming privacy they cannot provide.

IsSiteSafe's answer:

Two groups. Developers and system administrators checking the configuration of sites they run - the header, SSL and email authentication tools are aimed at them. And people who have been sent a shortened link, a QR code or an email that feels wrong, and want to find out what it actually is before clicking it.

IsSiteSafe's answer:

It started as a security header scanner built for my own use. An hour into writing it I realised that a tool which fetches any URL a stranger types is also a machine for attacking your own internal network - a classic SSRF vulnerability - and that the defence was more interesting than the scanner.

That set the tone for the rest of it. Each tool exists because I wanted an answer that existing tools gave in jargon, or gave only after a signup. The SSRF protection was later extracted and published separately as an open-source Python module.

IsSiteSafe's answer:

Static HTML, CSS and vanilla JavaScript on the front end, with no framework and no build step. The server-side checks are Python using only the standard library, with no third-party dependencies. Served by Apache behind Cloudflare.
