Snapshots all four versioned Docusaurus sections at v6.1.0, cut from master after the version-cutting tooling (#39837), broken-internal- links fix (#40102), and user_docs rename (#40171) all landed. With the rename in place, all four sections now produce parallel-named files at the docs/ root (no more bare `versioned_docs/` outlier). Versioning behavior: lastVersion stays at current for every section, so the canonical URLs (/user-docs/..., /admin-docs/..., /developer-docs/..., /components/...) continue to render content from master. The current version is consistently labeled "Next" with an unreleased banner, and 6.1.0 is a historical pin accessible only via its explicit version segment. Component playground: previously disabled: true in versions-config.json, now enabled and versioned. Snapshot includes: - All MDX content for the four sections. - Auto-gen captured fresh: 74 database pages (engine spec metadata), ~1,800 API reference files (openapi.json), 59 component pages (Storybook stories). - Data imports frozen at cut time into snapshot-local _versioned_data/ dirs: user_docs_versioned_docs/version-6.1.0/_versioned_data/src/data/databases.json (canonical 80-database diagnostics from master, preserved by the generator's input-hash cache) admin_docs_versioned_docs/version-6.1.0/_versioned_data/data/countries.json admin_docs_versioned_docs/version-6.1.0/_versioned_data/static/feature-flags.json developer_docs_versioned_docs/version-6.1.0/_versioned_data/static/data/components.json - Import paths in deeply-nested files rewritten so they still resolve from one directory deeper inside the snapshot. - developer_docs/extensions/overview.md snapshot has the FIXED ./mcp.md form (from #40102), so the SPA-nav 404 isn't baked into the 6.1.0 version. Verified via full yarn build: exit 0, no broken links surfaced by onBrokenLinks: throw.

Overview
Apache Superset's extension system enables organizations to build custom features without modifying the core codebase. Inspired by the VS Code extension model, this architecture addresses a long-standing challenge: teams previously had to fork Superset or make invasive modifications to add capabilities like query optimizers, custom panels, or specialized integrations—resulting in maintenance overhead and codebase fragmentation.
The extension system introduces a modular, plugin-based architecture where both built-in features and external extensions use the same well-defined APIs. This "lean core" approach ensures that any capability available to Superset's internal features is equally accessible to community-developed extensions, fostering a vibrant ecosystem while reducing the maintenance burden on core contributors.
What are Superset Extensions?
Superset extensions are self-contained .supx packages that extend the platform's capabilities through standardized contribution points. Each extension can include both frontend (React/TypeScript) and backend (Python) components, bundled together and loaded dynamically at runtime using Webpack Module Federation.
Extension Capabilities
Extensions can provide:
- Custom UI Components: New panels, views, and interactive elements
- Commands and Menus: Custom actions accessible via menus and keyboard shortcuts
- REST API Endpoints: Backend services under the
/extensions/namespace - MCP Tools and Prompts: AI agent capabilities for enhanced user assistance
UI Components for Extensions
Extension developers have access to pre-built UI components via @apache-superset/core/components. Browse all available components on the UI Components page and filter by Extension Compatible to see components available to extensions.
