OnyxStack Labs

OnyxStack Labs is a software development agency specializing in custom software, web and Android application development, ERP systems, and AI-driven automation. We work directly with startups, SMEs, and growing businesses to design and build production-ready digital products — from internal tools and dashboards to full-scale web platforms.

Our team builds on a modern stack including React, Firebase, and current AI tooling, with a focus on clean architecture, fast performance, and long-term maintainability. We operate on a fixed-scope pricing model, so clients know their budget and timeline upfront with no surprise costs once development starts.

Clients work directly with the engineers building their project — no account managers or ticket queues in between.
