Which Clash Client Should You Use on Desktop? Clash Plus, Verge Rev, and FlClash Compared

Understand the Difference Between Clients, Cores, and Subscriptions

When choosing a Clash desktop client, the most common confusion is the difference between the client interface and the proxy core. Clash Plus, Clash Verge Rev, FlClash, and Clash Nyanpasu mainly handle configuration management, system proxy toggles, tray menus, log viewing, and core lifecycle management. The mihomo core usually does the actual work of parsing rules, establishing proxy connections, handling DNS, and routing traffic through TUN.

mihomo retains the rule and protocol capabilities of Clash Meta. When two clients use the same mihomo version, YAML configuration, and nodes, their core forwarding performance usually does not differ by an order of magnitude. The practical differences are more often caused by default DNS settings, TUN parameters, core startup arguments, configuration overrides, and the resource usage of the interface process itself.

A Subscription Does Not Determine the Client Type

A subscription link is simply a source of configuration. Standard Clash YAML commonly includes fields such as proxies, proxy-groups, and rules, and can be read by multiple mihomo clients. A generic Base64 node subscription may not import directly; the provider must offer Clash format, or the content must first be converted to compatible YAML. Switching clients will not automatically fix format errors or change node quality.

Before migrating, export local overrides, scripts, and custom rules. Copying only the subscription URL usually restores just the portion supplied by the provider; direct rules, DNS settings, LAN listening options, and proxy-group selections added locally may need to be recreated.

How the Four Clients Differ

Clash Plus: A Shorter Path to First-Time Setup

Clash Plus is a good fit when the goal is simply to import a subscription, choose a node, and enable the proxy. For people who use system proxy settings mainly with Windows browsers, office software, and common desktop apps, fewer entry points can matter more than a long list of advanced features. After installation, first confirm that the subscription has updated and that the proxy group has selected a working node, then enable the system proxy.

Before choosing it, check which core the current build uses, whether it provides TUN controls, whether logs show rule matches, and whether local settings are preserved during configuration updates. Users who need complex scripts, multiple override layers, or frequent DNS changes should verify these capabilities before migrating.

Clash Verge Rev: Complete Desktop Controls

Clash Verge Rev uses mihomo as its primary core. Common features include subscription management, rule-mode switching, system proxy, TUN, service mode, connection lists, and logs. On Windows, open Settings → Clash Settings to check the mixed port and LAN listening, and enable TUN in the same area. The secondary grouping may vary slightly between releases.

It suits users who maintain work, personal, and temporary test configurations at the same time. Configuration overrides can separate a provider subscription from local DNS settings, rule providers, or listening ports, so subscription updates do not directly rewrite the remote YAML. The more override layers you add, however, the more important it becomes to inspect the final effective configuration when troubleshooting rather than checking only the original subscription.

FlClash: Consistent Workflows Across Devices

FlClash uses Flutter for its interface, so its desktop and mobile layouts follow a similar structure. People who switch frequently between Windows, Linux, and Android can spend less time searching for settings. Proxy groups, connections, logs, and configuration files are generally clearly separated, and touch-based controls feel relatively natural as well.

The trade-off is that the interface process usually uses more baseline memory than a minimal native shell. The impact is limited on a 16 GB computer, but a difference of several dozen to more than 100 MB still matters on 4 GB or 8 GB devices, remote desktop sessions, and low-power mini PCs. If the client runs only in the background tray, compare its resident usage after closing the main window rather than the peak shown immediately after opening Settings.

Clash Nyanpasu: More Advanced Entry Points

Clash Nyanpasu is aimed at desktop users who want to adjust configuration, core, and interface behavior. It offers robust multi-profile management, log inspection, rule-group switching, and tray controls, making it suitable for testing different subscriptions or keeping multiple environments. More entry points also mean that first-time users should review the defaults one by one, especially for the system proxy, TUN, DNS, and mixed port.

When migrating to Nyanpasu, do not run the old client at the same time. If both programs try to bind 7890, 7891, or the same control port, the core launched later will report that the address is already in use. Windows system proxy settings may also be taken over by whichever client wrote them last, creating a situation where one interface says the proxy is enabled while traffic is actually entering the other program.

How to Compare Resource Usage and Startup Speed

Resource usage cannot be judged from a single process in Task Manager. Desktop clients often include an interface process, the mihomo core, an updater, and WebView or rendering child processes. Compare the complete process group under the same configuration, and wait for subscription updates, latency tests, and rule loading to finish.

A Reproducible Local Test

The test machine used a Core i5-1240P, 16 GB of RAM, and Windows 11 24H2 build 26100. The configuration contained 186 nodes, 12 proxy groups, and about 48,000 local and rule-set entries, using mihomo v1.19.10. After a cold start, each client ran for 10 minutes with the main window closed but the tray process retained; the average working set was calculated from three readings. These results illustrate the general scale and should not replace measurements on other systems.

These differences do not translate directly into proportional changes in proxy throughput. Proxy speed is primarily determined by node bandwidth, latency, protocol implementation, encryption overhead, DNS response time, and rule matching. On a 16 GB computer, a client using 130 MB or 230 MB will usually make no visible difference during a single page load; on memory-constrained devices, the gap becomes more apparent when switching tabs, resuming from sleep, or running multiple apps in parallel.

The Practical Difference Between System Proxy and TUN

System proxy settings work well for browsers, chat tools, and desktop programs that read the operating system proxy configuration. A typical setup uses the mixed port 7890 to accept both HTTP and SOCKS traffic. After the system proxy is enabled, Windows writes the setting for the current user, but terminal programs, games, some Store apps, and software with its own network stack may ignore it.

TUN mode uses a virtual network interface to capture a broader range of IP traffic, making it suitable for apps that do not read system proxy settings. A mihomo TUN configuration commonly involves stack, dns-hijack, auto-route, and auto-detect-interface. On Windows, creating the interface and changing routes require administrator permissions, so clients often use service mode to avoid prompting for permission on every launch.

mixed-port: 7890
mode: rule
tun:
  enable: true
  stack: mixed
  auto-route: true
  auto-detect-interface: true
  dns-hijack:
    - any:53

This configuration only illustrates a common structure and should not directly replace an existing subscription. If WSL, Hyper-V, Docker Desktop, a virtual machine, or a corporate VPN is also running locally, automatic routing may choose the wrong interface. If internal network access fails, first disable TUN and test the system proxy, then check interface priority, bypassed subnets, and DNS routing.

TUN Considerations for the Four Clients

• Clash Plus: First confirm whether the current version offers TUN and a service installation option. If you only proxy browser traffic, there is no need to force-enable TUN for the sake of completeness.
• Clash Verge Rev: A good choice for Windows users who need service mode, TUN at startup, and detailed mihomo settings. After enabling it, check the service status and logs.
• FlClash: Suitable for users who want similar TUN workflows on desktop and mobile, although system permissions and routing behavior still depend on each platform.
• Clash Nyanpasu: Suitable for users willing to inspect core settings and startup logs. After switching cores or configurations, confirm that the TUN fields are still supported.

To verify that TUN is working, do not rely only on the color of the toggle. Open the Connections page, start an app known not to read system proxy settings, confirm that the corresponding process or destination connection appears, and check whether the rule matched DIRECT, a proxy group, or REJECT. If nothing appears on the Connections page, the issue is usually in traffic capture or routing; if a record appears but access fails, continue checking the proxy group, DNS, and node.

Configuration Management, Rules, and Troubleshooting

For long-term use, configuration management matters more than the home screen’s appearance. A subscription may update its nodes every day, but local setups still need private network ranges to bypass the proxy, development domains to be routed separately, DNS overrides, and rules for specific programs. A client that can show the final configuration, identify rule matches, and expose core logs is better suited to complex environments.

Four Entry Points to Check

1. Configuration: Can you update the subscription manually, see its last update time, switch profiles, and receive an HTTP status or parsing error when an update fails?
2. Proxies: Can you distinguish proxy-group types, select a node manually, and view latency-test results? Zero latency or a timeout does not necessarily mean a node is dead; also check the test URL and DNS.
3. Connections: Can you filter live sessions by domain, process, rule, and policy, and close old connections manually? Existing TCP sessions do not migrate automatically after you switch nodes.
4. Logs: Can you see configuration parsing, port binding, DNS, the TUN interface, and rule-match details? Use info first when troubleshooting, and switch to debug temporarily when more detail is needed.

Clash Verge Rev and Nyanpasu are better suited to users who need overrides and diagnostics; FlClash keeps a similar page structure across devices; Clash Plus focuses on reducing the number of steps during first use. If you do not need to manage local rules over time, advanced override support will not automatically improve connection quality.

What to Look for in Update Frequency

“Updated frequently” does not simply mean more client releases. Check the interface version, bundled mihomo version, rule-set update method, and operating-system support separately. A client may release several times in a month while its core remains outdated, leaving protocol and DNS fixes unavailable. Conversely, a slower interface release cycle that allows independent updates to a stable core may be a better fit for a fixed work environment.

Before updating, record the current client version, mihomo version, and a configuration backup. After a major update, verify in order: the program starts, the subscription parses, ports are listening, the system proxy is written, the TUN service is running, and common domains match the expected rules. Change one variable at a time to avoid upgrading the client, core, and configuration simultaneously and then losing the ability to locate the problem.

Choose by Use Case

First-Time Users: Start with Clash Plus

When all you need is to import a subscription, choose a node, and enable the system proxy, Clash Plus offers a more direct workflow. After installation, keep rule mode enabled, confirm that browser access and connection records work, and only then consider TUN, LAN sharing, and custom DNS. Every additional toggle introduced during initial setup expands the troubleshooting surface.

Primary Windows PC: Start with Clash Verge Rev

When you need startup launch, service mode, TUN, configuration overrides, connection inspection, and full logs, Clash Verge Rev offers a well-balanced desktop management experience. It is especially suitable for environments that combine development tools, terminals, WSL, and browsers. When using TUN, keep explicit direct-connection rules for corporate networks, virtual-machine subnets, and the home LAN.

Desktop and Mobile Together: Consider FlClash

If you switch frequently between Windows, Linux, and Android, FlClash’s similar interface structure reduces workflow differences. It suits users who value consistent habits across devices more than the lowest possible resident memory. On lower-spec computers, disable live charts you do not need and reduce continuously running latency tests.

Multiple Profiles and Advanced Tuning: Consider Nyanpasu

If you keep work, home, test, and backup configurations at the same time and regularly inspect core behavior, Nyanpasu provides more management entry points. The prerequisite is being willing to understand how ports, overrides, DNS, and TUN interact. Do not enable every advanced option at once; first establish a basic configuration that starts reliably.

Low-Memory Devices and Remote Desktops: Measure Background Usage First

On 4 GB or 8 GB devices, compare the complete process group after closing the main window instead of drawing conclusions from the technology name. Run the same configuration continuously for 30 minutes and record memory usage, CPU wakeups, and resume-from-sleep behavior. If you only proxy browser traffic, the system proxy is usually simpler than TUN and avoids virtual-adapter and routing conflicts.

A Safer Client Migration Checklist

1. Record the subscription URL, current proxy-group selection, mixed port, DNS settings, and TUN status in the old client.
2. Export local YAML files, override files, scripts, and custom rules instead of relying only on the remote subscription.
3. Disable the old client’s system proxy and TUN, exit its tray process, and confirm that ports such as 7890 have been released.
4. Install the new client, import one configuration, and initially enable only rule mode and the system proxy.
5. Use the Connections page to confirm that browser traffic enters the new client and that domains match the intended policies.
6. Install the service and enable TUN only when needed, then verify terminals, games, virtual machines, and internal network addresses.
7. After two or three days of stable use, remove the old client while keeping a bootable copy of the configuration.

If the new client reports a YAML parsing failure after import, use the line number in the logs to check indentation, colons, and list structure. YAML uses spaces for indentation, not tabs. If the configuration loads but no nodes appear, check whether the subscription response is actually Clash YAML rather than Base64 text, a login page, or a rate-limit message.

If the browser works after enabling the system proxy but the terminal still connects directly, the applications use different proxy mechanisms; the client is not necessarily the wrong choice. Set HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY as required by the terminal tool, or use TUN after confirming routing compatibility. The proxy address is usually 127.0.0.1:7890; use the port shown in the client’s current configuration.
