# xstate vs query

xstate and query share 8 technologies: React, Solid, @angular/core, Angular, Preact, Svelte, Vue, and vue-demi. Both are written in TypeScript.

- [statelyai/xstate](https://seerepo.com/r/statelyai/xstate): State machines, statecharts, and actors for complex logic
- [TanStack/query](https://seerepo.com/r/TanStack/query): 🤖 Powerful asynchronous state management, server-state utilities and data fetching for the web. TS/JS, React Query, Solid Query, Svelte Query and Vue Query.

## What they share and what sets them apart

- In common: React, Solid, @angular/core, Angular, Preact, Svelte, Vue, vue-demi
- Only in xstate: Zod, Ajv, saxes
- Only in query: Lit, @lit-labs/ssr, preact-render-to-string, @solid-primitives/storage, Next.js, goober, @kobalte/core, solid-primitives, @tanstack/solid-virtual, solid-transition-group, react-error-boundary

| Activity | Last push November 7, 2026, 5,990 commits, 30,421 stars | Last push November 9, 2026, 5,949 commits, 50,546 stars |
| Tests | 398 test files. 19.3% of its code files have a test that imports them | 413 test files. 49.1% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
