Get upgrade estimateIs your Angular codebase holding you back?
Outdated versions can lead to security vulnerabilities, slow performance, and development bottlenecks. Don't let legacy code limit your growth.
Security risks
Unsupported versions don't receive security patches, leaving your application and users exposed to threats.
Performance
Each new Angular version brings performance improvements. Older apps miss out on faster load times and a smoother UX.
Integration challenges
Modern tools and libraries often lack support for legacy Angular versions, complicating development and feature additions.
Action required: Angular LTS deadline approaching
As of October 2025, any application running on Angular v16 or older has passed its End-of-Life (EOL). This means no more security patches from Google, leaving your application vulnerable to potential exploits. Modernizing isn't just an upgrade, it's essential for security and compliance.

Frequently asked questions
The timeline varies depending on the project's size, complexity, and the version gap. A small project might take a few days, while a large enterprise application could take several weeks. We provide a detailed time estimate after our initial analysis. Nevertheless, we strive to complete upgrades within a reasonable timeframe.
We strive to minimize downtime. Our process involves working on a separate branch and deploying to a staging environment for testing. When project is ready for the production deployment, approach it carefully during off-peak hours to ensure a seamless transition with minimal disruption.
Cost is determined by the scope of work. After our initial free analysis, we provide a comprehensive, transparent proposal with a fixed price or a detailed estimate, so you know exactly what to expect. We welcome projects of all sizes and budgets.
We do accept AngularJS projects, however in most cases the only realistic way to maintain the project is to gradualy migrate the codebase to latest Angular. Such migration can be complex (depending on a project) as when it comes to implementation details it is an completely different framework. This yields massive benefits in performance, security, and developer experience.
