Web apps · AI · Šaleška Valley
We build web apps and AI for manufacturing, the public sector, and growing companies in Velenje, Šoštanj and the Šaleška Valley. From the first call to launch.


RSLabs d.o.o. is a software agency in Slovenia (Velenje and Šoštanj) that builds custom web applications, integrates AI into business workflows, and leads digital transformation—from discovery to contact.
RSLabs is the local development partner in the Šaleška Valley. We build custom web applications, put AI into real workflows, and digitalize work that Excel and a brochure site cannot cover.
Offices in Velenje and Šoštanj. HeatAtlas, our urban heat platform, won the GZS SAŠA gold award in June 2026. We bring that same product thinking to custom systems for local companies.

Our process is transparent and iterative.
We understand your goals, tech stack, and constraints. We scope the project and agree on deliverables before writing a single line of code.
Iterative builds with modern frameworks and best practices. Regular demos and feedback loops keep you in the loop every step of the way.
We take your solution live: deployment, clear documentation, and ongoing support. We're not done until it runs reliably and you trust it in production.
Expert development for your digital future
Custom web apps, APIs, and integrations. We build scalable, secure solutions tailored to your business needs.

AI integration, automation, and intelligent systems. From chatbots to predictive analytics, we bring AI to your workflows.

Architecture reviews, technology audits, and strategic advice. We help you choose the right stack and avoid costly mistakes.

We use modern, proven technologies: React, Node.js, Python, cloud platforms (AWS, Azure, GCP), and databases suited to each project. We choose the right stack based on your requirements, scalability needs, and existing systems.
We start by understanding your data and use cases. We evaluate build vs. integrate (e.g., LLMs, APIs) and prototype early. We focus on solutions that are maintainable, ethical, and aligned with your business goals.
Timelines depend on scope and complexity. Small projects (MVP, landing pages) can take 4–8 weeks. Larger applications or AI integrations typically run 2–6 months. We provide a realistic timeline during discovery.
Yes. We offer post-launch support, bug fixes, updates, and optional retainer agreements for ongoing development. We can scope maintenance as part of the project or as a separate engagement.
Security is built in from the start: secure coding practices, encryption, access controls, and compliance with relevant standards. We can address GDPR, industry-specific regulations, and data handling requirements.
Yes. We integrate with legacy systems, ERPs, CRMs, and third-party APIs. We assess your current stack and design solutions that fit your ecosystem without disrupting existing workflows.
We have offices in Velenje and Šoštanj and work with companies in the Šaleška Valley. We build custom web apps and AI, not brochure websites. From the first call to launch.
