## Runtime requirements

| SDK / capability                    | Requirement                    |
| ----------------------------------- | ------------------------------ |
| Collaboration Server with SQLite    | Node.js 22+                    |
| Collaboration Browser Client        | A browser supported by Web SDK |
| AI SDK                              | Node.js 22.12+                 |
| CLI Screenshot, Render, Layout Lint | Chrome, Chromium, or Edge      |

Applications may use npm, pnpm, Yarn, or another package manager. The installed package's
`engines` and native dependency requirements are authoritative.

> [!NOTE: Version alignment]
> This documentation corresponds to `1.0.0-rc.0`. Every `@univerjs/*`, `@univerjs-pro/*`, and
> `@univer-cli/*` package in one application must use this version.

See [Collaboration Packages](https://docs.univer.ai/server/collaboration/packages.md) and [CLI Packages](https://docs.univer.ai/ai/packages.md) for package
selection and installation.
