Thanks for Zernio - I have just discovered it, but I love it already!
Founder, Factology.Systems
I use Zernio for my SaaS purplepalm.ai. Integration was incredibly easy - had everything up and running in less than an hour. The API is super straightforward.

I spent a long time looking for a simple solution for integration into the self-hosted version of n8n. Zernio was just perfect! I highly recommend it to everyone.

This concept to have an API first social media scheduler is just phenomenal! The amount of time saved, the automation capabilities is unlike anything else.
Social Media Manager
Easiest set-up ever, great reliability, saves me hours per week. I love how you can customize the message for each platform starting from the same content.

Zernio makes programmatic multi-platform social posting as simple as I've ever seen it. The API is straightforward, well-documented, and simple. It just works.
