We build tools that hold up over time
ER Informatique is an independent digital studio based in Geneva. We design and build websites, applications and business platforms for companies that need a tool made for them.
We have chosen to stay small on purpose. You deal directly with the people designing and building your project, which removes the middle layer, shortens decisions and avoids the expensive misunderstandings that come with them.
Our projects span very different sectors — healthcare, veterinary, mobility, education, architecture, marketplaces — but the approach stays the same: understand the business before proposing a solution, deliver in stages, and stay reachable once the project is live.

What guides our work
One point of contact
You talk to the person writing the code. No chain of intermediaries between what you need and what gets built.
Quotes we stand by
Scope and budget are fixed during scoping. Any change is priced and approved before work starts on it.
Maintainable code
Proven technologies, documented code and hosting you control. You are never locked in to one supplier.
Support after launch
Backups, security updates and monitoring. A delivered project is a project we keep looking after.
Proven tools, chosen to last
We use technologies that are widely adopted and actively maintained. That means your project can be picked up, extended or hosted elsewhere if you ever choose to.
- Next.js & React
- TypeScript
- PostgreSQL
- Prisma
- Flutter
- Node.js
- Tailwind CSS
- Three.js & GSAP
Four stages, from first conversation to launch
Scoping
We start from your real processes and constraints. By the end of this stage, the scope, the budget and the schedule are written down.
Design
Wireframes of the main screens and the data model. You approve the structure before the first line of code is written.
Development
Delivered in stages on a test environment you can open at any time. You follow the progress instead of discovering it at the end.
Launch & support
Deployment, data migration, training for your team, then maintenance and further development over time.
Have a project in mind? Let’s talk.
A first conversation costs nothing and usually clears up a great deal.
