As answered by people managing IsSiteSafe and Ember-cli.
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.
