Push / In-app Messaging SDK
The clearest split is that Courier has a free tier while Braze does not. Braze is Customer engagement platform with push, in-app messages, email, SMS, WhatsApp, and Canvas journey orchestration; Courier is Multi-channel notification API routing messages across email, push, SMS, Slack, and in-app with template. The data points Braze at mobile app engagement and user lifecycle messaging, and Courier at mobile app engagement and user lifecycle messaging. Pricing: Braze is subscription from $10; Courier is freemium, free tier. Lock-in is high for Braze and medium for Courier, with DX at 5/5 vs 4/5 and transparency at 1/5 vs 4/5. On listed strengths, Braze emphasises mobile app engagement and user lifecycle messaging, and Courier emphasises mobile app engagement and user lifecycle messaging. Only Braze lists an enterprise tier in the data. 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
Braze is for mobile; Courier is for mobile; decide based on whether a free tier matters.

Entry pricing is listed as $10 for Braze and unknown for Courier. Courier offers a free tier while Braze does not, so initial cost favors Courier. Total cost at scale depends on usage and plan details that are not in this dataset, so confirm with each vendor.
Braze is tagged with high lock-in (engagement platform, deep user data). Courier is tagged with medium lock-in (proprietary routing, templates portable). At least one side is high lock-in, so budget migration time for re-implementing integrations.
The dataset rates Braze at 5/5 for developer experience and Courier at 4/5, so Braze 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. Courier is flagged as not for web-only products without mobile, so confirm your context does not fall there. Note that moving from Braze to Courier means gaining access to a free tier.
