Angularnone0/10The only testing-related evidence (angular-comm-9) references Protractor for legacy AngularJS, not modern Angular's CLI/dev-server e2e integration (e.g., Cypress/Playwright schematics); no docs or evidence pack items describe an official, out-of-the-box e2e testing setup for current Angular.
State logic unit testing
developerUnit test my reactive state and logic without needing to render the DOM
weight 2 · round to AngularSveltenone0/10No documentation or first-party evidence describes testing Svelte state/logic without DOM rendering; the only relevant community comment explicitly calls out a lack of clear unit testing solution or docs (svelte-comm-11), reinforcing the absence rather than establishing the capability.

Angular Signals provide state independent of the DOM (angular-docs-1) and community evidence notes Angular's dependency injection and testing tools (Karma/Protractor) make testing easy (angular-comm-9), implying logic can be tested in isolation. However, there is no direct evidence or docs excerpt describing unit testing signals/services without rendering components, TestBed usage, or DOM-free testing patterns. Missing for 10: explicit documentation of TestBed/service-only unit tests, examples of testing signals without component rendering, independent corroboration of DOM-free testing workflow.

Ai assisted type inference fixes
ai-native developerUse AI tooling that automatically resolves type errors surfaced by the framework's type system
weight 2 · round drawnSveltenone0/10No evidence of any AI tooling that resolves type errors from Svelte's type system; evidence only covers general framework features, community sentiment, and IDE support complaints (svelte-comm-15).
Angularnone0/10There is only a vague mention of 'AI-forward resources and integrations' (angular-docs-4) and an llms.txt file for AI discoverability, but no evidence of AI tooling that automatically resolves type errors surfaced by Angular's type system (e.g., language service integration with AI code-fixers). missing for 10: any documented AI tool/agent integration that reads Angular compiler/type errors and auto-fixes them, evidence of adoption or hands-on validation of such a workflow.

Ide autocompletion
developerGet accurate autocompletion and inline type errors in my editor via a language service integration
weight 3 · round drawnSveltenone0/10The evidence pack contains no first-party documentation of an official Svelte language server, VS Code/IDE extension, or type-checking tool (svelte-check), and the only related comment is a community complaint that 'IDE support has been an issue' (svelte-comm-15), which is negative rather than confirming. Since axis clearly applies to a TypeScript-capable UI framework but no supporting evidence is present, verdict is none.

Angularnone0/10The evidence pack contains no first-party documentation of an Angular Language Service or editor-integration feature providing autocompletion/type-checking; the only related comment (angular-comm-3) states that Angular's template-as-string approach prevented editors from doing intellisense, tag matching, or catching typos at compile time, which is the opposite of what the story asks for. No corroborating evidence shows this capability actually being delivered.

Angularnone0/10The evidence pack only shows general TypeScript adoption claims and community reactions to strong typing in Angular's history, but nothing documents automatic type inference for @Input/@Output component props or emitted events specifically. No first-party docs or hands-on evidence address this precise TypeScript-DX capability.
Typed templates
developerGet compile-time type checking inside my component templates, not just script blocks
weight 2 · round drawnSveltenone0/10No evidence pack item addresses template-level type checking (e.g., TypeScript in markup/bindings via svelte-check); only general framework descriptions and community sentiment are present, with one comment noting IDE/TS support issues (svelte-comm-15).
Angularnone0/10No evidence in the pack documents Angular's compiler doing strict type checking inside templates (e.g. strictTemplates/Language Service); the only directly relevant community evidence (angular-comm-3) states the opposite — that template variable typos 'fail silently instead of causing compile errors.' Missing for 10: any first-party docs on strictTemplates/template type checking, any independent confirmation of compile-time errors surfaced from templates.

ai-native userGet AI-generated insights and suggestions from my data inside the product
weight 2 · not comparableSvelten/aSvelte is a UI compiler/framework, not a data product or application that surfaces AI-generated insights from user data; this axis is a category error for a framework.
Angularn/aAngular is a front-end development framework/platform, not a data-driven application with an internal analytics or insights feature; the story about AI-generated insights from 'my data inside the product' is a category error for a UI framework, even though it offers AI-forward developer tooling resources (angular-docs-4) unrelated to data insights.
ai-native userSet up automations that run autonomously in the background
weight 2 · not comparableSvelten/aSvelte is a UI compiler/framework for building frontend components, not an automation or agent-orchestration platform; setting up autonomous background automations is outside its category entirely.
ai-native userDelegate tasks to a built-in AI assistant inside the product
weight 3 · not comparableSvelten/aSvelte is a UI compiler/framework, not an agent or assistant product; there is no concept of a 'built-in AI assistant' for this category, making this axis a category error.
Angularnone0/10Angular.dev mentions 'AI-forward resources and integrations' but this refers to external AI tooling guidance, not a built-in AI assistant inside the product that a user can delegate tasks to. No evidence of an in-product agent or assistant capability.

ai-native userDownload a machine-readable API spec (OpenAPI or equivalent)
weight 2 · not comparableSvelten/aSvelte is a UI compiler/framework, not an API service; OpenAPI specs apply to HTTP APIs, not a frontend framework, so this axis is a category error rather than a missing capability.
Angularn/aAngular is a frontend framework/library, not a service or API product; there is no REST/GraphQL API surface for which an OpenAPI spec would be applicable. The llms.txt found is a documentation index for LLMs, not a machine-readable API spec, and does not change the category mismatch.
ai-native userTest against a sandbox environment without touching production data

ai-native userDo everything through the API that I can do in the UI
weight 2 · not comparableSvelten/aSvelte is a UI compiler/framework, not a service with a UI/API duality; there is no product 'UI' whose functionality would be mirrored by an API. This story applies to SaaS-style products with both a UI and API surface, which is a category error for a frontend framework.
Angularn/aAngular is a frontend framework/library, not a SaaS product with a distinct UI and API surface to compare — there is no 'UI' whose functionality could be mirrored by an API. This story applies to products with a hosted UI and programmatic API, which is a category mismatch for a framework.

developerBuild native desktop applications by reusing my framework's component model and tooling
weight 2 · not comparableSvelten/aSvelte is a web UI compiler/framework; the evidence pack is entirely about browser-based rendering and web app development (SvelteKit, DOM updates, etc.) with no mention of a native desktop app toolkit or native component model. Building native desktop apps is a different product category (e.g., Tauri/Electron), so this axis does not apply to Svelte itself.
Angularnone0/10Evidence describes Angular as a platform for building mobile and desktop *web* applications, but there is no mention of a native desktop app framework (e.g., Electron/Tauri-style wrapper or NativeScript-style native rendering) that reuses Angular's component model for native desktop targets.
developerReuse my framework skills and code to build performant native mobile apps for iOS and Android
weight 2 · not comparableSvelten/aSvelte is a web UI compiler framework targeting browser/DOM rendering; no evidence of a native mobile app compilation target (like React Native). Native mobile app development is a different product category (Svelte builds web apps, possibly wrapped via third-party tools, but no first-party native mobile story exists).
Angularnone0/10No evidence pack item mentions native mobile app development (e.g., NativeScript, Ionic, or similar) for iOS/Android; all evidence concerns Angular's web-app framework capabilities and performance debates. Angular.dev's tagline even explicitly frames it as for 'web apps,' with no mention of native mobile support.
ai-native userChoose where my data is stored (region/residency)

ai-native userOpt out of telemetry and usage tracking
weight 2 · not comparableSvelten/aSvelte is a UI framework/compiler, not a service or CLI tool that collects telemetry or usage data from developers; there's no evidence of any telemetry system to opt out of, and the concept doesn't apply to this kind of product.
Angularn/aAngular is a frontend framework, not a telemetry-collecting service or CLI tool with usage tracking that would need an opt-out; this axis targets developer tools/agents that phone home data, which is a category error for a UI framework itself. Angular CLI telemetry is not addressed in evidence, but the story as framed for the framework itself is not a fair fit.
developerCheck a public status page and incident history for the framework's official hosting/deploy platform before relying on it in production
weight 2 · not comparableSvelten/aSvelte is a UI compiler/framework, not a hosting/deploy platform with an official managed service — there is no official hosting infrastructure whose uptime/incidents would need a status page. This axis is a category error for a framework itself (deploy platforms like Vercel are separate third-party products).
