# Plugins reference — Manage and configure agent plugins

> Manage installed plugins for stagewise AI coding agents. Configure credentials for Figma, GitHub, Supabase, PostHog, Vercel, and Remotion integrations.

Open **Settings → Agent → Plugins**.

## Viewing installed plugins

The plugins page lists built-in plugins with name, description, provided skills, and credential configuration status. Plugins are built into stagewise. Community or user-installed plugins are not supported.

## Plugin credentials

Some plugins need credentials — API keys, access tokens, or other secrets. Credentials are encrypted on your machine.

| Field type     | How it's stored                                                  |
| -------------- | ---------------------------------------------------------------- |
| **Secret**     | Encrypted at rest, never exposed in plaintext (API keys, tokens) |
| **Non-secret** | Stored as plaintext (project IDs, usernames, region names)       |

Configure credentials by clicking on a plugin in the list.

## Plugin apps

Plugins can ship interactive mini-apps that render inside the chat sidebar. The agent opens these automatically:

* **Figma** shows a node preview when you reference a design
* **Supabase** displays query results in a table
* **GitHub** shows pull request details inline

Apps communicate with the agent via `postMessage` for two-way interaction.

## Built-in plugins

| ------------ | ---------------------------------------------------------------- |
| **Figma**    | Access designs, real-time selection monitoring via CDP           |
| **GitHub**   | Repository access, issues, pull requests, actions, releases      |
| **Supabase** | Run SQL queries, manage edge functions, inspect migrations       |
| **PostHog**  | Query analytics with HogQL, manage feature flags, inspect events |
| **Vercel**   | Manage deployments, read logs, configure environment variables   |
| **Remotion** | Create and edit videos in React                                  |

Built-in plugins are always available and cannot be removed. stagewise does not load community plugins.
