Reviewed & updated:
ROSTAN Technologies builds robust, scalable applications on open-source technology because it removes per-seat licensing costs and vendor lock-in without any compromise on enterprise readiness. Our full-stack team delivers custom web applications, APIs, microservices, and internal platforms using React, Angular, Node.js, Python, PHP, and Laravel — chosen per project on technical fit, not on which stack we happen to prefer. Every build follows the same discipline regardless of language: clean architecture that a second team can maintain after we hand it over, automated testing rather than manual QA as the safety net, and CI/CD from the first commit rather than bolted on before go-live. A large share of our open-source work is legacy modernisation — bringing an ageing PHP or jQuery application to a current, secure, maintainable stack without a risky big-bang rewrite — because most businesses do not have the luxury of a clean-slate rebuild and need the migration path, not just the destination.

FAQ
Frequently Asked
Frequently Asked
Questions
Why choose open source over proprietary solutions?
Open source eliminates licensing costs, provides full code ownership, offers greater flexibility and customization, and benefits from large community support and frequent security updates.
Do you provide ongoing support for open source applications?
Yes, we offer managed support, hosting, monitoring, security patching, and feature development for all applications we build using open source technologies.
Can you migrate our legacy application to modern stack?
Yes, we specialize in migrating legacy applications to modern frameworks like React, Laravel, and Node.js with minimal disruption to your business operations.
Can you take over an existing codebase mid-project?
Yes — we regularly inherit an in-progress application from another agency or an in-house team that has moved on. We start with a short codebase audit before committing to a timeline, so we are not guessing at scope.
Do you sign an NDA and hand over full source code ownership?
Yes, standard on every engagement — you own the repository, the code, and all IP outright, with no licensing fees or platform lock-in, which is the core reason to choose an open-source stack in the first place.
