Push / In-app Messaging SDK
The clearest split is that Courier uses a freemium model and Apprise uses a free model. Courier is Multi-channel notification API routing messages across email, push, SMS, Slack, and in-app with template; Apprise is Push / In-app Messaging SDK tool for developers. Specializes in notification library. The data points Courier at mobile app engagement and user lifecycle messaging, and Apprise at mobile app engagement and user lifecycle messaging. Pricing: Courier is freemium, free tier; Apprise is free, free tier. Lock-in is medium for Courier and low for Apprise, with DX at 4/5 vs 5/5 and transparency at 4/5 vs 5/5. On listed strengths, Courier emphasises mobile app engagement and user lifecycle messaging, and Apprise emphasises mobile app engagement and user lifecycle messaging. Neither lists an enterprise tier, so contract-level buying may require a direct conversation. Honest trade-off: neither fits web-only products without mobile, so if that is your context, look elsewhere; otherwise pick on the pivotal factor above and the DX score that matters most to your team.
Quick take
Courier is for mobile; Apprise is for mobile; decide based on which pricing model fits your budget.

The dataset rates Apprise at 5/5 for developer experience and Courier at 4/5, so Apprise scores higher. That score reflects overall polish rather than any single integration, so trial both against your stack before committing.
Yes for teams whose workload matches mobile, since both list the same fit. Apprise is flagged as not for web-only products without mobile, so confirm your context does not fall there.
