Clash Verge Rev vs FlClash: Which Client Should You Choose in 2026?

Overview: Two Leading Clash Clients

Since the original Clash for Windows was archived in late 2023, the community has coalesced around several successor projects. Two names consistently rise to the top of recommendations: Clash Verge Rev and FlClash. Both are open-source, both use the mihomo (Clash Meta) core, and both offer modern interfaces. But they differ significantly in architecture, design philosophy, and target audience.

This article provides a thorough, feature-by-feature comparison to help you decide which client fits your needs. Whether you are installing Clash for the first time or migrating from another client, this guide covers every dimension that matters. If you need installation help for either client, our Windows installation guide covers Clash Verge Rev step by step, and our tutorial hub includes platform-specific instructions for both.

Architecture and Technology Stack

Clash Verge Rev

Clash Verge Rev is built on Tauri, a framework that uses the system's native webview for the frontend and Rust for the backend. This results in significantly smaller binary sizes (typically 5-10 MB) and lower memory consumption compared to Electron-based applications. The native webview means the UI renders using the operating system's built-in browser engine: WebView2 on Windows, WebKit on macOS, and WebKitGTK on Linux.

The backend logic is handled by Rust, which communicates with the mihomo core through its RESTful API. Configuration management, profile override processing (including JavaScript and Lua scripting), and system integration are all handled on the Rust side.

FlClash

FlClash is built on Flutter, Google's cross-platform UI toolkit. The entire application -- frontend and backend logic -- is written in Dart and compiled to native code for each platform. This gives FlClash a significant advantage in cross-platform consistency: the same Dart codebase runs on Windows, macOS, Linux, Android, and iOS with minimal platform-specific adjustments.

Like Clash Verge Rev, FlClash uses the mihomo core for actual proxy operations. The Flutter layer handles the UI, configuration management, and system integration, delegating proxy functionality to the core via its API.

Platform Support

This is where the two clients diverge most sharply. Clash Verge Rev is a desktop-only client, while FlClash targets all major platforms including mobile. If you want a single client ecosystem across your desktop and phone, FlClash is the clear choice. If you only need a desktop client, Clash Verge Rev's desktop-specific features may appeal more.

User Interface and Design

Clash Verge Rev

Clash Verge Rev features a clean, functional interface with a dark theme by default. The layout follows a sidebar navigation pattern: Dashboard, Profiles, Proxies, Connections, Logs, and Settings are accessible from the left panel. The dashboard shows real-time traffic charts, active connections, and quick toggles for system proxy and TUN mode.

The UI is responsive and fast, benefiting from the lightweight Tauri framework. Custom CSS themes are supported, allowing advanced users to completely overhaul the appearance. The interface prioritizes information density over visual flair, which power users tend to appreciate.

FlClash

FlClash uses Material Design 3 principles, resulting in a more visually polished and animated interface. Transitions between screens are smooth, and the overall aesthetic feels more modern and consumer-friendly. The app supports both light and dark themes with system-following options.

FlClash's mobile interface is particularly well-designed, with touch-optimized controls and responsive layouts that adapt to different screen sizes. On desktop, it offers a comparable experience to Clash Verge Rev but with more visual polish at the cost of slightly higher resource usage.

Feature Comparison

Both clients support the core Clash feature set because they both rely on the mihomo core. The differences lie in the client-level features: profile management, system integration, and user interface capabilities.

Configuration Depth

For most users, both clients provide more than enough configuration options. However, power users who rely heavily on profile customization will notice differences.

Clash Verge Rev: Script Profiles

Clash Verge Rev's killer feature is its script profile support. You can write JavaScript or Lua scripts that receive the entire Clash configuration as an object, modify it programmatically, and return the modified version. This enables incredibly dynamic configurations:

• Auto-generate proxy groups based on node names
• Conditionally add rules based on time of day
• Merge multiple subscriptions into a single unified config
• Inject custom DNS entries or modify logging behavior

FlClash supports merge profiles (YAML overlay) but does not offer the same level of scripting flexibility. For users who need to transform configurations beyond simple key-value overrides, Clash Verge Rev is the stronger choice.

Both: Merge Profiles

Both clients support merge profiles, which use YAML deep-merge to layer custom configuration on top of imported subscriptions. This is sufficient for most customization needs, including adding rules, modifying DNS settings, and injecting proxy groups. For a complete walkthrough of configuration techniques, see our rule configuration tutorial.

Performance and Resource Usage

Since both clients delegate proxy operations to the mihomo core, the core proxy performance is identical. The differences are in the client layer's resource footprint.

Memory Usage

Clash Verge Rev, built on Tauri, typically consumes 80-150 MB of RAM at idle. FlClash, built on Flutter, tends to use 120-200 MB at idle due to Flutter's rendering engine overhead. On systems with ample RAM (16 GB or more), this difference is negligible. On memory-constrained devices (older laptops, 8 GB systems), Clash Verge Rev has a measurable advantage.

CPU Usage

Both clients are CPU-efficient at idle. Under load (active proxying with many connections), CPU usage is dominated by the mihomo core, which is the same in both cases. The client layer adds minimal CPU overhead in both implementations.

Disk Space

Clash Verge Rev installers are typically 5-10 MB. FlClash installers are 20-40 MB due to Flutter's bundled engine. On mobile, FlClash APKs are in the 30-50 MB range. Neither is excessive by modern standards, but Clash Verge Rev's footprint is notably smaller.

TUN Mode Implementation

TUN mode is critical for users who need to proxy all system traffic, not just browser traffic. The two clients handle TUN mode differently.

Clash Verge Rev

Clash Verge Rev uses a service mode approach. It installs a system service that runs with elevated privileges, creating and managing the virtual network interface. This means you do not need to run the main application as administrator. The service mode also enables TUN mode activation with a single toggle.

If the service mode fails to install, Clash Verge Rev provides an in-app button to reinstall it. Troubleshooting is straightforward. For a complete TUN mode guide, read our TUN mode transparent proxy tutorial.

FlClash

On desktop, FlClash also supports TUN mode but may require the application to run with administrator privileges on some platforms. On Android, FlClash uses the system VPN API to achieve similar functionality, which is the standard approach for mobile transparent proxying.

FlClash's TUN implementation is functional but offers less granular control over the stack mode and DNS hijacking compared to Clash Verge Rev's desktop implementation. For most users, the difference is academic; for advanced users who need to fine-tune TUN behavior, Clash Verge Rev provides more knobs.

Update Frequency and Community

Clash Verge Rev

Clash Verge Rev has a large and active development team. Releases typically come every 2-4 weeks, addressing bugs, adding features, and updating the bundled mihomo core. The GitHub repository has tens of thousands of stars and an active issue tracker. The community is primarily Chinese-speaking but increasingly international.

FlClash

FlClash is a newer project but has gained rapid traction thanks to its cross-platform promise. Updates come every 2-6 weeks. The GitHub repository is growing quickly, and the development team is responsive to feature requests. The community is more internationally distributed from the start, partly due to Flutter's global developer base.

Both projects are healthy and show no signs of stagnation. Choosing between them based on maintenance risk is not a concern in 2026.

Verdict: Which One Should You Use?

There is no single "best" client. The right choice depends on your specific needs:

Choose Clash Verge Rev if:

• You primarily use desktop (Windows, macOS, or Linux) and do not need a mobile client.
• You want the most powerful profile override system with JavaScript/Lua scripting.
• You value global hotkeys, rich tray menus, and deep system integration.
• You prefer the smallest possible resource footprint.
• You want custom CSS theming for the interface.

Choose FlClash if:

• You want a unified client experience across desktop and mobile.
• You value a polished, Material Design interface with smooth animations.
• You are on Android and want a native Clash client with full TUN support.
• You prefer Flutter's cross-platform consistency over platform-native feel.
• You are willing to trade some configuration depth for simplicity.

Can I use both?

Yes. Some users run Clash Verge Rev on their desktop for its scripting and hotkey capabilities, and FlClash on their Android phone for a consistent mobile experience. Since both use the same mihomo core and the same configuration format, your subscription profiles work identically in both clients. There is no lock-in.
