We've made a conscious effort over the past few months to increase the number of integrations. Integrations are a solid source of backlinks and more importantly traffic, Zapier, for example, is our 3rd largest attributable acquisition source.
Following that effort, the first app to integrate with us is https://carrd.co – which most Indie Hackers will be familiar with. It's an amazing simple-to-use drag/drop landing page builder. It's super affordable too which is massively important to our users, many of whom use us for that same reason.
