Hey Product Hunt! I'm Daniel, a CISO and IT infrastructure lead from Croatia. I built Geslar because every password manager I evaluated for work required something I wasn't willing to give: my email, my data on someone else's server, or a subscription. What makes Geslar different: - NO ACCOUNT — you don't even need an email to use it - NO CLOUD — your vault lives on your device, nowhere else - NO TELEMETRY — zero analytics, zero tracking, zero knowledge - FREE — not freemium, actually free (all features, no limits) Security model: - AES-256-GCM encryption - PBKDF2-SHA256 with 600,000 iterations - Shadow DOM isolation for autofill - CSP protection - Master key exists only in RAM Bonus: passphrase generator from 5,700+ Croatian words across 8 regional dialects. "krava-čokolada-tramvaj-oblak" is easier to remember than "M@rk0_2024!" and takes 4 trillion years to brute force. The ecosystem: 1. geslar.app — web generator + password checker (HIBP) 2. Škrinjar — browser extension (Chrome, Firefox, Edge, Opera) 3. Ključar — standalone TOTP/HOTP authenticator (iOS/Android) Available in Croatian and English. EU infrastructure (Hetzner, Germany) planned for cloud sync in the future. I'd love your feedback — especially on the security model. Happy to answer any questions.
