Rheo vs Wireflow

Rheo is a mobile platform for designing and changing app flows, then comparing variants without waiting for App Store reviews. Its canvas supports onboarding, paywall, win-back, and upsell journeys with branches and targeting. Teams can test holdouts and variants in flow structure, copy, and timing, and review conversion and revenue. Rheo says its inputs, layouts, animations, and system moments render natively on iOS and Android, not in a WebView. React Native is supported; Swift, Flutter, and Kotlin are marked as coming soon. After SDK integration, teams publish flows for the app to pick up. The dashboard includes flow completion measures and funnel and cohort views. Rheo Engage handles broadcasts and automations through a customer's SES, Resend, Postmark, or SendGrid account. Integrations named include RevenueCat, AppsFlyer, Adjust, and Superwall. Pricing includes a free plan and paid plans from $49.99/mo. The free plan includes 400 MAU and no experiments; exceeding an included MAU quota pauses the SDK until the next month or an upgrade.

Wireflow is an online tool for creating user flow prototypes in a browser. It requires no installation and provides more than 100 custom-built graphics and cards for web elements, interactions, and use cases. Coworkers can be invited to design flows together in real time, with built-in live chat. Project permissions control access and let a flow be public or private. The editor autosaves flows in the browser and includes an Export JSON action. The site lists 102 flow templates across 10 categories. Wireflow is MIT licensed, developed in the open, and can be forked or self-hosted. Its README documents local development with yarn and Docker Compose. The Free plan is free, available forever without sign-up, and includes the graphics and cards, real-time collaboration, project permissions, live chat, and browser access. Listed platforms are web and self-hosted.
