// about
A small studio, built for speed
Fluxis Labs is a Serbia-based digital studio focused on high-performance frontend and Python automation. We work with clients in the Balkans and worldwide, and keep the team small so every project gets direct attention - no account managers, no handoffs into a black box.
We care about clean, tested code and interfaces that feel fast. If it does not ship well or run well, it is not done.
Whether you need a landing page, a web app, a scraper, or an API that ties systems together - we build it to last and to move quickly.

Common questions
How much does a project cost?
It depends on scope. Small landing pages and focused automation scripts start lower; full apps and multi-system integrations cost more. After a short discovery call we send a clear written estimate - fixed price or phased, your choice.
Do you work with clients outside Serbia and the Balkans?
Yes. Fluxis Labs is based in Serbia and works remotely with clients across the Balkans and worldwide. English and Serbian are both first-class - you get the same delivery from anywhere on the planet.
How long does a typical project take?
Many landing pages and scrapers ship in 1-3 weeks. Larger apps or pipelines usually take 4-8 weeks. We agree on milestones up front so you always know what lands when.
What does collaboration look like?
You talk directly with the people building your product. We work in short cycles, share demos you can click, and keep async updates in a shared channel so nothing gets lost.
Do you offer maintenance after launch?
Yes. We can stay on for bugfixes, small iterations, or a monthly retainer. If you prefer a clean handoff, we document everything and leave you ready to run it yourself.
Which technologies do you use?
Frontend: React, Next.js, TypeScript, and Tailwind. Automation: Python, FastAPI, Playwright, and Pandas. We pick the stack that fits the problem - not the other way around.
How fast do you reply?
We aim to answer every inquiry within 24 hours on business days. Urgent production issues for active clients get priority.
