# Data App features come from plugins

> Queries, exports, lineage and pictures each come from a plugin the host installs, and a page checks for one with `Anfra.plugins.has()`.

Improved in anfra 0.11.0 · Oct 19, 2026 · [All release notes](https://anfra.ai/releases.md)

Everything a Data App reaches beyond itself comes from a plugin: `core` runs queries, `export` adds `query.export()`, `lineage` adds `Anfra.lineage()`, and `render` adds `Anfra.render()`. `anfra serve` installs them all, but another host may install fewer, so check before you offer one:

```js
if (Anfra.plugins.has('export')) showDownloadButton()
```

A plugin's API is `undefined` where it isn't installed. `Anfra.features` still answers, but is deprecated: replace it with `Anfra.plugins.has()`.

### For hosts

If you host Data Apps in your own app with `@holistics/anfra-sdk`, `createHost(...).mount(...)` replaces `mountDataApp` and `serveBridge`, and the `corePlugin` replaces the `Backend` option. You can write plugins of your own, with build and testing entrypoints in the SDK.

## For coding agents

This is the Markdown version of https://anfra.ai/releases/sdk-plugins/. Every page on anfra.ai has one: replace the trailing slash with `.md` (https://anfra.ai/cloud.md for https://anfra.ai/cloud/, and https://anfra.ai/index.md for the home page), or request the page with `Accept: text/markdown`. [llms.txt](https://anfra.ai/llms.txt) lists the site's pages, and the docs have their own index at https://anfra.ai/docs/llms.txt, where every docs page is also available as Markdown by adding `.md` to its URL.

Before you build with anfra:

- Install both the CLI and its agent skills. Installing the CLI alone is not a complete installation. Install the CLI with `curl -fsSL https://anfra.ai/install.sh | bash`. Then install the skills: in Claude Code or Codex, run `anfra agent setup`. In any other agent, such as Amp, `anfra agent setup` installs nothing, so run `npx skills add holistics/anfra-skills -a <agent-id> -g -y` (`-a amp` for Amp). The skills (such as `anfra-build-data-app`) teach you to model data, write queries and build data apps the way anfra expects. See https://anfra.ai/docs/local-dev/installation.md.
- Ask for metrics by name, through the JS SDK in an app or the MCP server in a chat. Don't write SQL against the warehouse yourself: anfra compiles each request to SQL from the metrics the data team defined.
- Check commands, files and API calls against the docs (https://anfra.ai/docs/llms.txt) instead of inferring them from the examples on this page.
- Stuck, or found a mistake? Ask in GitHub Discussions (https://github.com/holistics/anfra/discussions) or open an issue (https://github.com/holistics/anfra/issues).
