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.
Modernize your Angular app
Expert Angular maintenance, seamless upgrades, and performance tuning. We keep your app secure, fast, and future-proof.
Get an estimateAngular 20 reaches End-of-Life in November 2026
Angular v19 and older have already passed their End-of-Life (EOL), and v20 is next. End-of-Life 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.

The evolution of Angular
Innovation by innovation, from its revolutionary origins to today's lightning-fast framework.
The road ahead
- AI-first developer experienceDeeper integrations with Gemini, the MCP server and agentic tooling, so AI can write idiomatic Angular alongside you.
- Faster builds with tsgoAn Angular compiler compatible with the Go-based TypeScript compiler could bring a 5-10x step change in type-checking speed.
- Accessible by defaultAngular Aria headless primitives maturing toward stable, with built-in keyboard, focus and screen-reader support.
- Less boilerplateIdeas like selectorless components are being explored to cut ceremony - on hold for now while the team weighs the tradeoffs.
The signal-first era
- Signal forms stableThe signal-driven forms API graduates to stable - composable, reactive and free of manual subscriptions.
- OnPush by defaultNew components default to OnPush, steering apps toward signal-based reactivity over Zone.js.
- AI tooling built inThe MCP server ships stable in the CLI, exposing Angular to AI agents and LLM workflows.
- Vitest everywhereVitest is the default for all new projects, retiring the older Karma and Jasmine setup for good.
Zoneless by default
- Zoneless out of the boxNew apps drop Zone.js by default for lighter bundles and clearer, faster change detection.
- Signal formsAn experimental, signals-based forms API that replaces valueChanges subscriptions with reactive composition.
- Vitest replaces KarmaVitest becomes the default test runner for new projects - faster, modern unit testing.
- Angular AriaHeadless, fully accessible UI primitives arrive in developer preview, handling ARIA and keyboard navigation for you.
Signals come of age
- Signals stabilizedeffect, linkedSignal and toSignal reach stable, making fine-grained reactivity production-ready.
- Incremental hydrationHydrate the UI on demand - by viewport or interaction - to cut JavaScript payloads and boost responsiveness.
- Zoneless developer previewRun Angular without Zone.js for lower change detection overhead and smaller bundles.
- httpResourceAn experimental, signal-driven way to fetch data over HTTP, built on the resource API.
Modern Angular
- Built-in control flowMore intuitive and ergonomic syntax for templates like @if and @for.
- Bundle size optimizationOptimized bundle size and performance with @defer for lazy-loading.
- Vite & esbuildImproved development server and fast build times for a better DX.
- SSR & hydrationImproved server-side rendering for better performance and SEO.
- Signal componentsSimple, built-in, and subscription-free reactivity for components.
The Angular renaissance
- Standalone componentsSimplified the architecture by making NgModules optional.
- Typed reactive formsProvided better data integrity and developer experience in forms.
- Signals introductionA new fine-grained reactivity model for significant performance gains.
Ivy & modernization
- Ivy rendererA complete re-architecture for smaller bundles and faster builds.
- Strict modeEnhanced type checking and improved code quality out of the box.
- Improved CLIThe Angular Command Line Interface became more powerful and efficient.
The great rewrite
- Component architectureShifted to a modern, tree-based structure for better organization.
- TypeScriptAdopted for robust, scalable, and maintainable enterprise-grade code.
- AOT compilationIntroduced ahead-of-time (AOT) compilation for faster rendering.
The foundation
- Two-way data bindingPioneered declarative data binding, simplifying UI state management.
- DirectivesIntroduced a powerful way to create reusable custom HTML elements.
- Dependency injectionA core concept that made components decoupled and testable.

Frequently asked questions
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.
