No description of LeetCode yet.
SecretDrop is a zero-knowledge secret sharing tool for developers. Files are encrypted in the browser using AES-256-GCM before they ever reach the server. The server stores only encrypted blobs and can never read your content, filenames, or passwords. Upload files, set a password, share a link....

As answered by people managing LeetCode and SecretDrop.dev.
SecretDrop.dev's answer:
True zero-knowledge encryption that happens entirely in the browser using only the Web Crypto API — no third-party crypto libraries, no server-side access to your data. It's as simple as upload, set password, share link — but with enterprise-grade cryptography underneath.
SecretDrop.dev's answer:
SecretDrop is an early-stage product — there's no public customer list to share. It's built for and used by indie developers, freelancers, and small agencies.
SecretDrop.dev's answer:
The real competitor is "paste it in Slack." Vault is heavy, enterprise tools are expensive and require setup. SecretDrop gives you zero-setup, encrypted-by-default sharing with a free tier — no accounts for recipients, no credit card, no infrastructure to manage.
SecretDrop.dev's answer:
Developers, freelancers, and small dev teams who need to share API keys, .env files, and credentials quickly and securely without spinning up a Vault instance or paying for enterprise tooling.
SecretDrop.dev's answer:
Built by a dev agency founder in Germany who got tired of watching teammates share database credentials and API keys over Slack every week. Not because they didn't care about security — because there was no frictionless alternative. SecretDrop was built to fill that gap.
SecretDrop.dev's answer:
React 19, Vite 6, Tailwind CSS 4, and shadcn/ui on the frontend. NestJS 11 with TypeScript on the backend. Astro 5 for the landing page. Supabase for auth, database, and storage. Web Crypto API (AES-256-GCM, PBKDF2) for all encryption. Polar for billing.
