A High-Level Comparison

Customer.io is a good fit for highly-resourced teams with large budgets and with dedicated engineering resources for a long setup and ongoing management.

However, most companies need their messaging to do more or are strapped for dev resources. That’s how we’re different. OneSignal aims to streamline your messaging workflow across teams and departments. We combine powerful no-code tools (from segmentation to automation and testing), a fast and unlimited API, and top-notch support. And those are just a few of the reasons OneSignal is a G2 Leader for easiest setup and implementation.

For over 2M users, OneSignal is a better choice.
