Flutter vs React Native is less of a performance argument than it used to be. Both frameworks have shipped the rewrite they'd been building toward for years: React Native's Fabric-based New Architecture and Flutter's Impeller renderer now ship by default in new projects rather than sitting behind an experimental flag. The real decision left on the table is which team you already have, what you're building, and what each stack actually costs to staff in Europe.
What changed: both frameworks shipped their rewrite
React Native's own architecture documentation states that as of version 0.76, the New Architecture is enabled by default in every React Native project, after several years of experimental opt-in that started with version 0.68. That's the release where the current rendering layer stopped being something a team had to turn on and started being what ships out of the box.
Flutter's own performance documentation places the equivalent shift a little earlier: as of the 3.27 release, Impeller became the default rendering engine on iOS and on Android running API 29 or higher, and it's the only rendering engine Flutter supports on iOS at all, with no Skia fallback to opt back into. Flutter extended the same default to desktop, macOS, Linux, and Windows, in version 3.47, with plans to remove the ability to opt out of Impeller entirely in a future release. Older Android devices without Vulkan support still fall back to the legacy OpenGL renderer, the one real exception left.
Both frameworks now ship their rewritten rendering and architecture layers by default, so performance comparisons built on older benchmarks may describe engines that are no longer the default. Team fit and platform scope carry more of the decision now.
Flutter vs React Native comparison table
| Factor | Flutter | React Native |
|---|---|---|
| Default rendering or architecture layer | Impeller (iOS and Android API 29+ since 3.27; desktop since 3.47) | New Architecture, default since 0.76 |
| Language | Dart | JavaScript or TypeScript |
| Where it tends to fit | One UI, one codebase, a small team optimizing for time to market | A team that already knows React, sharing logic with a web app |
Dart versus JavaScript is the real cost buried in that first row. A Flutter hire needs Dart specifically. A React Native hire can often come from a web React background, provided they've actually done the mobile-specific work covered below.
When Flutter wins
David Tengeri, a senior engineer at HighCircl with 17 years in software, frames the decision without much hedging: choose Flutter when you want a small, efficient team and one UI that looks and behaves the same on iOS and Android. It also spares a team from running two native builds toward the same feature. That's the shape of a lot of early teams: a single design, one codebase, and a release calendar that doesn't leave room for a native iOS build and a native Android build to drift out of sync.
The same interview with David Tengeri points to a second edge that's easy to overlook in a pure engine comparison: Flutter's ecosystem includes a hotfix tool, Shorebird, that ships patches straight to users without going through app store review, a process that can otherwise take one to five business days to clear a single fix. For a team that needs to kill a bug fast, that's an operational advantage the architecture comparison alone won't show you.
If SwiftUI and Jetpack Compose are also on the table alongside Flutter and React Native, the fuller four-way breakdown of native versus cross-platform UI frameworks lives in HighCircl's guide to declarative UI frameworks.
When React Native wins
React Native wins the opposite case: a team that already has React engineers, especially ones who've worked on a related web app, and wants to reuse that skill set and share business logic between web and mobile instead of building a mobile team from zero. The New Architecture changed a lot of what's happening under the hood, but it didn't change the core pitch: a component model and a lot of the same libraries a React team already knows, aimed at two more platforms.
It also tends to be the better fit when an app depends heavily on native modules already written for an existing native codebase, camera pipelines, Bluetooth integrations, background audio, where a team wants more direct control over how JavaScript talks to the native side.
What it costs to staff each one in Europe
The framework choice barely moves the number that actually matters: what you pay the engineer. HighCircl runs the same rate band for senior Flutter and React Native hires in Europe, €45-105/hr ($50-115/hr), with a margin capped at 20% and shown as its own line on top of what the engineer earns. About 1 in 10 applicants make it through a four-stage, engineer-led vetting process, background and experience verification, a communication and product-thinking assessment, a take-home technical project, and a live architectural-reasoning session, and a vetted shortlist ships in 72 hours once that's done.
Geography matters more than the rate does if your app handles EU user data. HighCircl delivers from seven countries, Poland, Hungary, Slovakia, Serbia, Slovenia, Romania, and Spain, with GDPR-native delivery from its EU member states; Serbia sits outside the EU, so it's outside that specific guarantee even though it's part of the same delivery footprint.
How to hire for whichever you pick
Once you've picked a framework, the harder problem starts: telling apart a candidate who's shipped production apps with it from one who followed a tutorial and put the same line on a resume. HighCircl's Flutter hiring guide covers current rates, a vetting checklist built around platform channels and Impeller, and the interview questions that catch candidates who've only read the docs. The React Native hiring guide covers the same ground for New Architecture fluency specifically, plus what to ask a web React engineer who says they're ready to ship mobile.
Both guides also cover the staffing math for a single cross-platform hire against running separate iOS and Android teams, which matters more once you're past the framework decision and into building the actual team.
FAQ
Is Flutter or React Native faster in 2026?
Neither framework's docs settle it with a single number. React Native's New Architecture ships by default since version 0.76, though its own docs note that enabling it may not immediately improve performance. Flutter's Impeller renderer ships by default since version 3.27 on mobile and 3.47 on desktop. In practice, speed depends heavily on how well a team knows the framework and how complex the app's UI is.
Does React Native still use a JavaScript bridge?
Not by default. React Native's own architecture documentation confirms the New Architecture ships in every new project since version 0.76, following several years where it was available only as an experimental opt-in. A project running an older React Native version, or one that hasn't upgraded, may still be on the architecture that came before it.
Is Impeller mandatory in Flutter now?
Depends on the platform. On iOS, yes: it's the only rendering engine Flutter supports there, with no fallback to the old Skia renderer. On Android running API 29 or higher, and on desktop as of Flutter 3.47, Impeller is the default, though older Android devices without Vulkan support still fall back to the legacy OpenGL renderer. Flutter's own docs say the ability to opt out of Impeller entirely is going away in a future release.
Should I hire a Flutter developer or a React Native developer first?
Start with whichever platform decision you've already made. If you've settled on one shared UI across iOS and Android with a small team, hire for Flutter first. If you've already got React engineers and want to extend a web product to mobile, hire for React Native first. Pick the framework once the product and team shape are clear; picking a framework before that usually means re-hiring once the real constraints show up.
