The wall

Your application works. That is when it gets complicated.

Between “it runs in my browser” and “a customer is paying to use it”, there is everything the AI did not write for you.

Putting it onlineIt runs in your AI tool's preview. Nobody told you where it lives afterwards, or who pays for the server.

Answering for securityYour customer will put their data in it — and their own customers' data too. Isolation, encryption, GDPR: this is no longer code, it is your liability.

Manage your customersAccounts, access, permissions, renewals: with three customers a spreadsheet will do, with thirty it will not.

Lasting over timeThe application does not stop on Friday evening. Updates, backups, incidents: someone has to be there.

Debugging what the AI wroteThe day it breaks inside a function you did not write, you are alone in front of the code.

LimeOS takes care of all five.The last one is the only one hosting alone will never solve: our experts read your vibe-coded code to find where the problem comes from.

Platform

A layer between your code and your customers.

LimeOS sits exactly where projects usually get lost: going live.

Hosting · Security · Maintenance

Infrastructure

Managed hosting

Your applications run on European infrastructure, with no configuration.

Security by default

Isolation, encryption and audit logs enabled from the very first deployment.

Maintenance handled

Updates, backups and monitoring: your applications stay in service without you having to watch over them.

Far more than a host.

An operating system for applications built with AI.

Plenty of people can host an application. Keeping it evolving over the years, making it reason and work with your customers' own data and tools is another story.

LimeOS rests on three technologies we have been developing for twenty-five years.

VDOM — Run

Your application is more than code deployed on a server. VDOM represents it as components: what the AI generated becomes an application model that LimeOS knows how to run, evolve and maintain over time.

Discover VDOM

VAILS — Reason

Intelligence no longer has to be rebuilt in every application: it is part of the system. Language models, logical rules, constraint solver, memory and orchestration become capabilities your application can use directly.

Discover VAILS

ODESA — Act

Your customers have files, business software and data that never leave their company. ODESA installs on their machines and lets your application work with that environment — only with the resources and rights they grant it.

And above them: LimeOS

HostSecureMaintainDistributeManage your customers

Customer management runs through the management portal, available as an option.

Three technologies under the hood. One platform to keep your applications alive.

Support

A team behind your applications.

On-call, updates and compliance are handled by LimeOS, not by you.

Included

You pay for your tools by the month. On LimeOS they are already there.

To deliver an application to a customer you currently stack four subscriptions: a host, a database doubled with an agent platform, an automation engine, and something to keep track of your own business. LimeOS comes with all four.
