# Connector catalog

> The 27 services you can connect, from Stripe and Slack to OpenAI and Shopify, plus the Custom API escape hatch.

Vaulter's catalog covers 27 of the highest-demand services, curated so that the things most apps need are one connection away. Here is what you can connect, by category.

## AI

- **Anthropic.** The Claude family of models.
- **Google Gemini.** Google's multimodal models.

## Communication and collaboration

## Two special entries

- **Supabase** is not a connector like the others; it is a full backend replacement. Connecting it moves your app's data home to a project you own. See [Bring your own Supabase](/docs/data/byo-supabase).
- **Custom API** is the escape hatch: connect any service with an API key, even if it is not in the catalog, and the agent can build against it through the same secure routing.

## Do not see what you need?

Tell us through [support](/docs/reference/troubleshooting), and describe what you are trying to build. Often an existing connector, or the Custom API entry, can already get you there.
