Customer.io vs OneSignal FAQ
- Which one is cheaper?
- OneSignal is the cheaper option, starting at $19/mo vs $100/mo for Customer.io.
- Can I use either one for free?
- OneSignal has a free plan. Customer.io doesn't — you'll need to pay from day one.
- How do they charge?
- Both use a hybrid model, so the comparison is straightforward — it comes down to features and limits at each price point.
- Which one is a better deal?
- Depends on what you need. Customer.io: Mid-market with a developer-friendly lean: the $100 entry is far below enterprise-grade tools like Braze, but there's no free plan or trial like some competitors offer. The 12-months-free Startup Program for companies under $10M raised is the real acquisition play, getting early-stage teams embedded before they scale into paid. OneSignal: OneSignal undercuts most messaging/engagement platforms at the entry point — $19/mo is cheap compared to Braze or Iterable, which don't even list prices because they're built for enterprise budgets. They're clearly playing a land-and-expand game: hook developers cheap, then monetize the ones who scale into custom contracts.
