A long-term partner, not a one-off job
Just IT is a software studio in Lithuania. Since 2020 we have built custom systems, AI solutions, online stores, mobile apps and websites, and connected them to the accounting, payments and couriers our clients already use.
We don’t hand over a project and disappear. Most of our work is long-term: once a system is live, we maintain it and keep developing it as the business changes. Developers, designers and testers from a network we trust join when a project needs them.
We work in English and Lithuanian with companies in Lithuania and abroad. As an EU company we work under GDPR, and Lithuanian time is one hour ahead of Berlin and two ahead of London.
PassLT
An app that prepares workers from outside the EU for the Lithuanian state-language exam, with seats their employers can buy. Built in Flutter for Android and iOS, with a Laravel back office.

You see the estimate before we write a line
You approve a plan with hours and a price for every part, then watch it get built.
- A call
- What you need, what you already use, and what must not break.
- Itemised estimate
- Design, development, testing and management, each with hours and a price. Nothing starts until you approve it.
- Milestones
- You see working software at every milestone, not only at the end.
- Long-term support and development
- We don’t disappear after launch: every project has a warranty period, then we maintain and develop the system, estimating each change first.
