Why outsource your application maintenance?

Keep your application secure. Frameworks, libraries and servers need regular updates to close new vulnerabilities.

Fix bugs before users complain. Monitoring and fast fixes keep your teams and customers working.

Never depend on one developer. A documented application maintained by a team removes the risk of a single person leaving.

Keep improving your product. A monthly budget for new features keeps your application in line with your business.

Security updates of an application’s frameworks and libraries
Takeover and audit of an existing application

We take over applications we did not build

Your developer left, your previous agency is no longer available, or nobody knows the code anymore? We audit the application, document it, fix the urgent issues and secure it before taking over its maintenance.

We work on Laravel, Symfony, Node.js, React, Vue and mobile apps. If the application is too outdated, we can plan a progressive rebuild with our custom web application development team.

Application maintenance pricing

Our application maintenance is billed as a monthly plan, based on the size of your application, the technologies used, the response times you need and the time reserved for new features, with no VAT or sales tax added.

The initial audit of an existing application is quoted separately. You receive a clear quote with no long commitment required.

Pay in 3 interest-free installments for projects over $1,000.

        Application maintenance: frequently asked questions

        What are application maintenance and support services?

        Application maintenance and support services keep software running after its launch: bug fixes, security updates, monitoring, performance improvements, user support and new features.

        Can you maintain an application built by someone else?

        Yes. We start with an audit of the code, dependencies and hosting, document the application, fix urgent issues, then take over its maintenance.

        How much does application maintenance cost?

        It is billed as a monthly plan, based on the size of the application, its technologies, the response times you need and the time reserved for new features, with no VAT or sales tax added.

        What is an SLA?

        A service level agreement defines response and resolution times according to the priority of each request, for example faster action for a blocking bug than for a minor issue.

        Which technologies do you support?

        We maintain applications built with Laravel, Symfony, PHP, Node.js, React, Vue and mobile frameworks such as Flutter and React Native.

        What is the difference between corrective and evolutive maintenance?

        Corrective maintenance fixes bugs and incidents. Evolutive maintenance adds or improves features so the application keeps up with your business.
