Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A type-safe router for React and other web UIs, with an optional full-stack framework built on it.
Open source · MIT
A routing library for AngularJS apps that maps URLs to nested app states and views.
The short answer
Choose TanStack Router if you need…
- React developers who want type-checked routes and URL parameters
- Teams building single-page apps that need schema-validated search params
- Developers who want to add server rendering later via TanStack Start
Choose UI-Router if you need…
- Teams maintaining an existing AngularJS 1.x application
- Developers who need nested views that follow URL structure
- Apps where deep-linkable, bookmarkable pages matter

What each one is
TanStack Router
TanStack Router is a routing library for web apps that aims to make navigation, URL parameters, and search parameters type-safe, so mistakes are caught by TypeScript. It also includes built-in caching, prefetching, nested layouts, and error boundaries. TanStack Start is a separate full-stack framework built on Router that adds server rendering and streaming, according to the README.
UI-Router
UI-Router is a client-side routing framework for AngularJS, the older 1.x version of Angular. It keeps the browser URL in sync with what the app is showing, so a user can bookmark a deep page inside a single-page app. Apps are organized as a tree of named states, and the library manages moving between them as a state machine.
Best for
TanStack Router
- React developers who want type-checked routes and URL parameters
- Teams building single-page apps that need schema-validated search params
- Developers who want to add server rendering later via TanStack Start
UI-Router
- Teams maintaining an existing AngularJS 1.x application
- Developers who need nested views that follow URL structure
- Apps where deep-linkable, bookmarkable pages matter
Strengths
TanStack Router
- Strong end-to-end type safety for routes, params, and loaders, per the README
- Schema-driven search params with validation
- Open source under the MIT license with an active project and a documented site
UI-Router
- Built around a hierarchical state tree that maps cleanly to nested views
- URL and app state stay in sync, which supports bookmarks and shareable links
- Includes tutorials, API docs, and a sample app linked from the README
Not ideal for
TanStack Router
- Non-developers, since it is a code library rather than an end-user tool
- Projects not using TypeScript or JavaScript, since the README centers on those languages
- Those who want a minimal router without a larger ecosystem, as the README pitches a family of related TanStack packages
UI-Router
- New projects: the README points newer work to separate UI-Router versions for Angular 2 and React, so this 1.x package targets AngularJS specifically
- Projects still on UI-Router 0.x, which the README says lives on a separate legacy branch
- Non-developers, since it is a code library with no standalone interface
Trade-offs
TanStack Router
- The README is truncated and gives few concrete setup details, so the full learning curve is unclear from it
- Start, the full-stack part, is a separate layer whose maturity this README does not detail
- Relies on the TypeScript ecosystem, which adds setup for those not already using it
UI-Router
- Targets AngularJS 1.x, an older framework; the README does not describe a migration path within this package
- The README is truncated and gives little detail on installation or configuration here
- Learning the state-machine model takes time for developers new to it
