Lynx vs React Native

React Native has been the default answer to cross-platform mobile for a decade, and Lynx is the first thing in a while that changes the shape of the question rather than the answer. ByteDance open-sourced it in March 2025 after running it in production across TikTok Studio and TikTok Shop. Both frameworks render real native views and ship to iOS and Android from one codebase, so the differences worth arguing about sit underneath that.

Threading

React Native's New Architecture removed the asynchronous bridge that defined its first decade. JSI lets JavaScript hold direct references to native objects, Fabric renders synchronously, and bridgeless mode has been the default since 0.76.

Lynx runs two threads by design, where the main thread does nothing but render and handle high-priority input while your application code runs on a background thread beside it. Because the main thread never waits on user code to draw the first frame, a Lynx screen can paint before your components have finished evaluating.

You feel the cost of that split when writing gesture code. A drag that tracks a finger at 60fps cannot round-trip to the background thread, so it runs in a main-thread worklet, a function that executes in the render realm with restricted access to your application state. React Native solves this with Reanimated worklets, so the concept transfers, and Lynx makes the two-realm model the baseline rather than an animation library you add.

Styling

React Native styles are JavaScript objects implementing a subset of CSS through Yoga's flexbox, with no cascade, no selector matching, and no stylesheet file.

Lynx parses actual CSS from actual stylesheets, so selectors, custom properties, media queries, keyframe animations, and transitions all work and Tailwind applies without an adapter layer. The limits are specific rather than structural, and the one that bites first is that the native engine resolves only a single level of var() indirection, so a token pointing at another token collapses.

Styling in Lynx feels like styling a website, and styling in React Native feels like configuring a layout engine.

Framework support

React Native is React, which for most teams is the reason to choose it, though it collapses the framework decision and the platform decision into one.

Lynx separates the rendering layer from the frontend that drives it. ReactLynx is the reference implementation and the most complete path, Vue Lynx provides a Vue 3 custom renderer that reuses @vue/runtime-core, and bindings for other frameworks are in progress. The Lynx team has said non-React frameworks already account for roughly half of the framework's usage internally.

For a Vue team this is the whole argument, because React Native offers no path that does not begin with learning React.

Web

React Native targets iOS and Android, and web support comes from react-native-web, a community project mapping React Native primitives onto DOM elements. It works as a translation layer rather than a first-class target.

Lynx treats web as a supported target with its own runtime, so the same source renders natively on mobile and through browser APIs on the web. Parity is not complete. Lynx dispatches raw mouse events without synthesizing touch, keyboard handling is thin because the framework was designed for touch first, and the accessibility-* properties that iOS VoiceOver and Android TalkBack consume are ignored by browsers. Component libraries close those gaps themselves, which Vy UI does for pointer input across every gesture surface.

Ecosystem

React Native wins the ecosystem comparison by a margin no architectural argument closes. It has ten years of libraries, Expo's toolchain, native module bindings for effectively anything you need, and a hiring pool that already knows it. If your project needs a mature ecosystem more than an architectural advantage, the comparison ends here.

Lynx is roughly a year into public life. The core is production-proven inside ByteDance at a scale most applications will never reach, third-party native modules are scarce, and component libraries number in the low single digits. Those are the official headless @lynx-js/lynx-ui for ReactLynx and Vy UI for Vue Lynx, compared in the libraries guide.

Choosing

Take React Native if you are shipping soon, need third-party native modules, are hiring against an existing talent pool, or already run it in production. The ecosystem advantage is real and it compounds.

Take Lynx if instant first-frame rendering matters to your product, if you want CSS rather than style objects, if the web target is a genuine requirement, or if your team writes Vue and rewriting into React is not a trade you want. You will occasionally be the first person to hit a given problem.
