About

Digital agencies and freelancers face a constant security liability: clients sending master passwords via plain-text email or Slack. Existing tools like 1Password are great for storage but high-friction for client collection, while "burn-after-reading" dev tools look unprofessional and "sketchy" to high-ticket clients.Keze.io is a "turnkey" SaaS designed to solve the agency onboarding bottleneck. It allows agencies to provide a branded, professional portal where clients can securely drop credentials.Zero Friction: No client account creation or sign-ups required.White-Labeled: Agencies use their own branding, logo, and custom domain to maintain professionalism.Zero-Knowledge: Mathematical privacy ensures the server never sees the raw data.The Tech Stack (Modern, Scalable, Low-Cost)Built for the "set-and-forget" founder, Keze uses a hyper-efficient, edge-native architecture:Frontend: Zero-dependency Vanilla HTML/JS (Blazing fast, no React-bloat, zero maintenance).Backend: Cloudflare Workers (Serverless compute at the edge).Database: Cloudflare D1 (Serverless SQLite).Security: Native Web Crypto API using AES-256-GCM. Decryption keys stay in the URL hash fragment and never hit the server.Keze is built with a 'No-Dependency' philosophy. Eschewing heavy frameworks like React or Hono, the application utilizes raw Cloudflare Worker fetch handlers and direct D1 SQL queries. This ensures the smallest possible cold-start times, absolute maximum edge performance, and a codebase with zero third-party security vulnerabilities. It is clean, idiomatic JavaScript designed to last for a decade without needing a framework update.Why I am SellingI am a senior product engineer and I built Keze to solve a genuine gap in the agency market. However, I am a busy father with other projects in the works, and do not have the ability or time to execute the marketing and sales motion this product deserves. The Growth Opportunity Keze is pre-revenue and ready for a marketer to take the reins. A buyer could achieve ROI quickly by:Direct Agency Outreach: Selling the tool as a "SaaS-buyout" for mid-sized agencies to use as an internal tool.SEO Play: Targeting "Onetimesecret alternative" or "Secure client onboarding" keywords.Product-Led Growth: Offering a "Free Forever" tier for individuals to drive viral adoption through the "Powered by Keze" footer on shared links.The Internal ToolYou do not have to run Keze as a public SaaS to get a massive ROI on this acquisition. This codebase is perfect for a mid-to-large digital agency, MSP, or IT consultancy looking to own their own proprietary, zero-knowledge onboarding portal.Instead of paying $60 to $100+ per month for enterprise tiers of Password.link or Keeper to get custom branding, you can buy the Keze IP outright. You pay a one-time fee of $4,900, host it for free on Cloudflare's edge network, and your agency owns a frictionless, white-labeled, military-grade credential pipeline forever. No per-seat licenses, no monthly SaaS bloat, and total ownership of the code.What’s IncludedFull Codebase: Frontend and Cloudflare Backend (GitHub Repo transfer).Premium Domain: Keze.io.Branding: Logo, UI assets, and design files.Pre-Built SEO Engine: Over 90 published, index-ready landing pages targeting high-intent, long-tail agency keywords. The content architecture is already live and aging on the domain, giving the new owner a massive head start on organic search acquisition.Support: 30 days of technical handover support to ensure a smooth transition.
