# Package catalog > Select every Univer CLI SDK package by content, collaboration, compilation, rendering, process, and application task. - Human documentation: [https://office.univer.ai/cli/packages](https://office.univer.ai/cli/packages) - Agent Markdown: [https://office.univer.ai/cli/packages.md](https://office.univer.ai/cli/packages.md) - Language: `en` - Source file: `content/docs/cli/packages.mdx` - Upstream source: [https://github.com/dream-num/univer-cli-sdk/blob/main/README.md](https://github.com/dream-num/univer-cli-sdk/blob/main/README.md) --- Univer CLI SDK currently publishes 25 independent packages. Install only the base packages the application needs, then add a command preset from the same row when its default terminal interaction fits the product. ## Two package roles | Role | Provides | | ---------------------- | -------------------------------------------------------------------------------------------------------------- | | Base package | Structured TypeScript APIs without depending on Commander or deciding command names, output, and exit behavior | | Command preset package | A native Commander `Command` backed by a base package, with default arguments, help, and terminal interaction | Command presets usually end in `-command`. Not every base package needs a corresponding command preset. ## Content and collaboration runtimes | Task | Base package | Command preset package | | --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------- | | Create standard headless Univer | [`@univer-cli/headless-univer`](https://www.npmjs.com/package/@univer-cli/headless-univer) | — | | Search the Univer Facade API offline | [`@univer-cli/api-reference`](https://www.npmjs.com/package/@univer-cli/api-reference) | [`@univer-cli/api-reference-command`](https://www.npmjs.com/package/@univer-cli/api-reference-command) | | Prepare and bind Facade execution | [`@univer-cli/content-execution`](https://www.npmjs.com/package/@univer-cli/content-execution) | — | | Read Sheet, Doc, or Slide content | [`@univer-cli/content-inspection`](https://www.npmjs.com/package/@univer-cli/content-inspection) | [`@univer-cli/content-inspection-command`](https://www.npmjs.com/package/@univer-cli/content-inspection-command) | | Run one collaborative Unit | [`@univer-cli/univer-collaboration-runtime`](https://www.npmjs.com/package/@univer-cli/univer-collaboration-runtime) | — | | Reuse collaboration runtimes in workers | [`@univer-cli/univer-collaboration-runtime-pool`](https://www.npmjs.com/package/@univer-cli/univer-collaboration-runtime-pool) | — | ##

Application helpers | Task | Base package | Command preset package | | ---------------------------------------------------- | -------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ | | Declare, read, and persist application configuration | [`@univer-cli/config`](https://www.npmjs.com/package/@univer-cli/config) | [`@univer-cli/config-command`](https://www.npmjs.com/package/@univer-cli/config-command) | | Query, cache, and export visual resources | [`@univer-cli/resource-library`](https://www.npmjs.com/package/@univer-cli/resource-library) | [`@univer-cli/resource-library-command`](https://www.npmjs.com/package/@univer-cli/resource-library-command) | ## How to choose 1. Start with the base package that matches the business task. 2. Add its command preset only when the default Commander interaction fits the product. 3. Use a collaboration runtime when the CLI, Web, and Server share a Unit instead of accessing the collaboration database directly. 4. Add a pool, daemon, or Render Runtime only when the application needs reuse, cross-process access, or browser rendering. 5. Read the target package README for its public APIs, ownership, and disposal behavior. See [Document loading and content operations](https://office.univer.ai/cli/content-operations.md), [Visual inspection](https://office.univer.ai/cli/visual-inspection.md), and [Runtime reuse and Daemon](https://office.univer.ai/cli/runtime-architecture.md) for concepts and core usage.
