You need to check DNS propagation, format some JSON, or run a quick SEO audit on a site. You Google a free tool, click the first result, and immediately get hit with "create a free account to continue" — or the actually useful features are behind a paywall.</p> <p>I got tired of that, so I built my own.</p> <p><strong><a href="https://www.siteindex.app" rel="noopener noreferrer">SiteIndex</a></strong> is 70+ free online tools with no signup and no paywall. Website auditing, network diagnostics, developer utilities, PDF tools — all running in the browser.</p> <h2> What's in there </h2> <p>Four categories:</p> <p><strong>Website &amp; Domain</strong> — the flagship is Website Score: a full SEO, performance, security, and accessibility audit of any public site. You can also embed a live score widget on your own website.</p> <p><strong>Internet &amp; Network</strong> — speed test, DNS lookup, propagation checker, port checker, ping, HTTP headers checker, SSL checker, and more.</p> <p><strong>Developer</strong> — JSON formatter, JWT decoder, regex tester, Base64, hash generator, cron job maker, UUID/ULID generators, and the rest of the daily-driver stuff.</p> <p><strong>Utilities</strong> — QR code generator, PDF merge/split, image tools, text manipulation, unit converters.</p> <h2> Why no signup? </h2> <p>Honestly, most of these tools have no business asking for your email. A JSON formatter doesn't need an account. Everything that can run client-side, does. No accounts to manage, no passwords to leak, no "free trial" that converts to a charge you forgot about.</p> <h2> Also: there's a Chrome extension now </h2> <p>Just published it — one click opens SiteIndex from your toolbar instead of digging through bookmarks.</p> <h2> Try it, break it </h2> <p>It's live at <a href="https://www.siteindex.app" rel="noopener noreferrer">siteindex.app</a>. I'd genuinely like to know:</p> <ol> <li>What's broken or slow?</li> <li>What tool is missing that you'd actually use?</li> </ol> <p>Roast away in the comments — that's the fastest way to make it better.</p> showdev webdev productivity tools
