# Application maintenance > Updates, fixes and new features after launch. We usually fix a problem before your customers notice it. Source: https://hoxger.com/en/services/maintenance ## Who it's for An application needs care after launch. Libraries age, browsers change and customers ask for new features. We handle it as it comes. ## What we do ### Updates We update libraries and the system before old versions turn into security holes. ### Fixes You report a bug to one person and know right away when it will be fixed. ### New features We add features in small steps, based on how customers actually use the application. ### Servers The application runs on our servers with backups and monitoring. You don't need a separate hosting company. Hostero We have maintained Hostero since 2023, and before that we ran the nhost.pl hosting service. We have just built it an entirely new panel, designed from scratch around how customers use it.

It's a fixed monthly fee you know in advance, together with a list of what it covers. It depends on the size of the app and how often it should change. You don't get a separate invoice for every small fix. ### Will you maintain an app someone else built? Yes. Before we take the app on, we review the code and tell you what's worth fixing first. Where it should run we decide together: it can stay on its current server or move to ours. ### Is maintenance required? No. After the 3 months of fixes after launch you can look after the app yourself or hand it to someone else, because the code is yours. Just keep in mind that an app without updates becomes easier to attack over time, so someone should look after it. ## Write to us. A few questions about your project, about two minutes.
