Launch websites with enterprise needs at startup speeds.

Hey Product Hunt! 👋 We just launched our Free Password Strength Checker — and it's unlike most tools you've seen. 🔐 No sign-up. No data collection. No uploads to any server. Everything runs 100% client-side in your browser, which means YOUR password never leaves your device — not even for a millisecond. Here's what it does: ✅ Instantly rates your password strength (Weak → Very Strong) ✅ Detects common patterns, dictionary words & repeated characters ✅ Gives you actionable tips to make your password stronger ✅ Works on mobile, tablet & desktop Why did we build this? Because most "password checkers" out there actually send your input to a server. That's a privacy nightmare — especially when people are testing real passwords. We wanted to build something people could trust completely. 👉 Try it free: https://www.thestackanalyst.com/... Would love your feedback! What feature would make this even more useful for you? 🙏
