[ ] **[nice-to-have]** Author standards-based web components and custom elements using the framework ## Ecosystem tooling - [ ] **[must-have]** Whether the framework is governed by a foundation or a single company, so I can assess long-term continuity and lock-in risk -

[ ] **[must-have]** Write components using standard HTML, CSS, and JavaScript syntax I already know, minimizing new concepts to learn - [ ] **[should-have]** Drop the framework into an existing server-rendered HTML page and render interactive components without rewriting the whole page - [ ] **[should-have]** Try an in-browser interactive tutorial to learn the framework hands-on without any local setup - [ ] **[should-have]** Follow a dedicated migration guide when moving between two incompatible major versions of the framework -

[ ] **[must-have]** Export all of my data in open formats and leave - [ ] **[must-have]** Self-host the core product - [ ] **[should-have]** Do everything through the API that I can do in the UI - [ ] **[should-have]** Read the product's source under an open license ## Performance - [ ] **[must-have]** Ship a small, dependency-light JS bundle to minimize runtime footprint and reduce supply-chain risk - [ ] **[must-have]** Stream server-rendered content so pages get faster perceived loads before all JavaScript arrives - [ ] **[should-have]** Use AI-powered devtools that analyze my component tree and suggest specific rendering or reactivity optimizations - [ ] **[should-have]** Build native desktop applications by reusing my framework's component model and tooling - [ ] **[should-have]** Rely on a compiler-optimized rendering system that updates the DOM without a virtual DOM diffing step - [ ] **[should-have]** Hydrate my server-rendered app progressively so pages become interactive faster - [ ] **[should-have]** How the framework's build and type-check times scale in large, multi-thousand-component codebases or monorepos - [ ] **[should-have]** Build large applications that stay fast and maintainable as my team and codebase grow - [ ] **[should-have]** Reuse my framework skills and code to build performant native mobile apps for iOS and Android ## Privacy posture - [ ] **[must-have]** Prevent my data from being used to train AI models - [ ] **[should-have]** Choose where my data is stored (region/residency) - [ ] **[should-have]** Control data retention and deletion - [ ] **[should-have]** Opt out of telemetry and usage tracking ## Ssr fullstack -

[ ] **[should-have]** Have AI generate component-level tests based on the props and reactive state my component declares - [ ] **[should-have]** Integrate official end-to-end testing tools that work out of the box with the framework's dev server - [ ] **[should-have]** Unit test my reactive state and logic without needing to render the DOM ## Typescript dx - [ ] **[must-have]** Get accurate autocompletion and inline type errors in my editor via a language service integration - [ ] **[must-have]** Get automatic type inference for component props and emitted events without writing extra type annotations - [ ] **[should-have]** Use AI tooling that automatically resolves type errors surfaced by the framework's type system - [ ] **[should-have]** Get compile-time type checking inside my component templates, not just script blocks - [ ] **[should-have]** Which TypeScript versions the framework officially supports so I can avoid compatibility breaks when upgrading either one --- Source: https://ultrametric.ai/productarena/arena/frontend-frameworks (evidence-graded verdicts for 5 products) · methodology: https://ultrametric.ai/productarena/methodology
