K3YSTONETECH is a product engineering studio that designs, builds, and operates SaaS platforms. From commerce to identity to entertainment — we ship products that work.
K3YSTONETECH FACILITIES Private Limited was founded in Bangalore with a mission to bridge the gap between physical infrastructure and digital innovation. Starting with facility management, we quickly recognized the transformative power of technology.
Today, we are a product engineering studio. We build and operate our own SaaS platforms — from e-commerce and payments to identity management and real-time file transfer. Every product we ship is proof of our capability.
Our stack is deliberate: Rust for performance, WebAssembly for extensibility, SQLite for simplicity. We don't just write code — we engineer products that last.

We prove our engineering by building and operating live SaaS products at scale
Every product here is live, functional, and built entirely in-house. This isn't theory — it's working software.
Multi-transaction e-commerce platform supporting Purchase, Rental, Subscription & Advance Booking — all in one unified system with custom branding.
Professional QR code generator with full customization, dynamic QR codes, and analytics tracking. Supports URLs, WiFi, vCards, and calendar events.
OAuth 2.1 & OIDC identity platform with Passkeys, MFA, and comprehensive audit logging. Built for modern authentication with WebAuthn support.
Enterprise-grade peer-to-peer file transfer. Files move directly between devices — zero server storage, end-to-end encrypted, GDPR/HIPAA compliance-friendly.
Online Tambola / Housie gaming platform for events and celebrations. Customizable tickets, budget control, hybrid online + offline play.
Under the hood, our products run on Blocks — a custom-built, multi-tenant application platform written entirely in Rust.
Blocks is a plugin-based application operating system. Every feature — from catalog management to payment processing — is a composable plugin that can be installed, configured, and combined to create complete business applications.
It's not a framework. It's not a CMS. It's a Rapid Application Development engine where entire business verticals are assembled from composable, sandboxed WebAssembly plugins.
We choose technologies for performance, reliability, and long-term sustainability. No hype-driven decisions — just engineering fundamentals.
We don't just build for ourselves. Our engineering capability is available to businesses ready to build serious software.
End-to-end product development from architecture to deployment. We build web applications, APIs, and microservices using modern, performant technologies.
We build SaaS products using our proven plugin-based architecture. Launch your business idea on a platform that's already battle-tested.
Strategic technology guidance for businesses looking to modernize their infrastructure, adopt new technologies, or architect scalable systems.
We're always building. These domains are reserved for upcoming products currently in research and development.
