Choose Braze if you are a mid-market or enterprise consumer brand with an app and engineers who can install its SDKs. Choose OneSignal if you are an app publisher or developer who wants an API without send limits. Braze is sold only through a conversation with sales. OneSignal starts with a free plan, then monthly paid plans, and sells its higher plans by quote.
A lifecycle team at a consumer brand with its own app gets the most from Braze when messages must react to outside data. Braze can pull live data from an outside service into a message partway through a journey. It also sends over WhatsApp from the same journey as push, email and SMS. Its limit is setup. The iOS, Android and web SDKs must be installed before any targeting works, so a team needs engineering support.
Alerting readers the moment a new post goes live is a job OneSignal handles with a WordPress plugin that fires a notification on publish. It lets developers send through its API with no cap on sends, on every plan. Its SDKs cover frameworks such as Flutter, Unity and React Native. Its own limit is that frequency capping, advanced analytics and exports begin on higher plans.
Braze's reviewers from 2025 praise the journey builder as intuitive and its support and learning resources as strong. Reviewers also call the personalization and AI-assisted features impactful. They say work can be lost because nothing saves automatically, and that built-in analytics and integrations feel limited. In reviews from 2018 to 2026, OneSignal's users find quick integration the strength, and they rate its SDKs and API as well documented. Some find reporting and advanced segmentation limited or slow to learn, and some call support slow.
A financial services company that offers cash advances before payday features in a Braze case study. The firm tests messages with a step that tries combinations of message elements.

The retailer credits app push with a share of its revenue, and personalization lifted click-through on web push.
