Bubble offers pre-built integrations with hundreds of popular services, including social networks (Facebook, LinkedIn), analytics (Mixpanel), and payments (Stripe). See the complete list of integrations.
Our no-code API connector hooks up to any JSON or XML-based API without any programming knowledge, and supports most popular authentication protocols out of the box. We also support connecting to major SQL databases, including MySQL, PostgreSQL, and MS SQL.
The Bubble platform is entirely open. You can create custom plugins using Javascript, and expose your own API to let other services connect to you.
