The stack

What we build on, and what we have built with it

Every technology on this page runs in one of our own products. None of them are here because they look good on a capabilities slide.

Next.js

KriyaXlabs is a Next.js development company in Mangalore, India, building on Next.js 16 with the App Router, React 19 server components and TypeScript. Five separate Next.js consoles run in Crampad Enterprise against one API, so the multi-tenant patterns are proven in our own production before they reach a client.

React

KriyaXlabs builds React 19 applications in TypeScript, usually inside Next.js. Our own products run several role-specific React consoles in production, so the component systems, state boundaries and accessibility patterns we bring to client work are ones we already maintain.

Flutter

KriyaXlabs builds Flutter applications for iOS and Android from a single codebase, including offline-first apps that ship with a bundled SQLite content bank. Crampad, our own study product, is a Flutter application backed by a NestJS API.

React Native

KriyaXlabs builds React Native applications for iOS and Android, typically for teams that already run React on the web and want one set of patterns across both. WorkPay, a gig-work payments product we are building for a client, runs on React Native with a Node.js and PostgreSQL back end.

NestJS

KriyaXlabs builds back ends on NestJS 11 and Node.js, with multi-tenant data isolation, organisation-scoped roles carried in the token, audit logging on every mutation, and OIDC single sign-on with SCIM 2.0 provisioning. Crampad Enterprise runs nine applications against one such API.

Python

KriyaXlabs uses Python for AI generation, verification and data pipelines. ExamXFlow is a Python system built on Vertex AI and Gemini that has produced a bank of 50,002 exam-realistic questions, each passed through an independent verification stage before it is allowed into the bank.

Supabase and PostgreSQL

KriyaXlabs builds on Supabase and PostgreSQL, using row-level security to enforce tenant isolation in the database rather than in application code. EduXFlow and WorkPay both run on this stack, and Crampad Enterprise uses PostgreSQL for institution-scoped data.

Vertex AI and Gemini

KriyaXlabs builds production systems on Google Vertex AI and Gemini, including agentic pipelines and verification gates that check model output before it reaches a user. ExamXFlow uses this stack to generate and independently verify exam questions; ArchXFlow uses it for agentic architectural design.
