Use your existing web devs — no Roku specialists required
Hosanna feels like React/SwiftUI. Your web and connected‑device engineers are productive on day one — shipping real Roku apps without touching BrightScript. Clean patterns, strong typing, and tooling your team already knows.
SceneGraph rendering with TV‑scale performance
Under the hood, Hosanna maps your declarative views to SceneGraph nodes and lifecycles. You get buttery navigation, virtualized lists and grids, and an animation system designed for 10‑foot UIs.
Build once. Ship to Roku today — more platforms ahead
Iterate quickly on the web, then deploy to Roku. Apple TV and Android TV targets are on our roadmap, using the same Hosanna codebase.
Open‑source framework. Licensed transpiler. Simple for clients.
Framework & TypeScript source: open source. Use, fork, and contribute freely.
Transpile technology: the proprietary toolchain that compiles Hosanna apps for Roku and other targets is commercially licensed.
Client projects: when Tantawowa builds your app, we grant a free production license for the transpiler for that app. No CLA nonsense.
We build your app, hand it over, and your team can support it themselves. The codebase is familiar, maintainable, and easy to extend.
We build. You own. Your team maintains.
Tantawowa partners with you to design and build your TV app with Hosanna, then hands over a clean repository. Your developers continue at full speed using TypeScript — not a niche stack. We're here for support and feature work when you want it.
