bubble.io is a popular no-code web application builder. You can use Bubble's SQL Connector plugin to connect to bit.io.
First, click "Add Plugin" and search for "SQL".

To configure the plugin, name the connection "bit.io", and change the connection type to "PostgresSQL".
For the connection string go to your repository page and click the big green "connect" button on the left.

Copy the connection string by mousing over the string and clicking "copy"

Back in Bubble you want to paste the connection string into the "Connection String" dialog. **You need to add `:5432/bitdotio
` after the `@db.bit.io
`**

Then click "Test Connection" and you're done!
