Clash Client Interface Walkthrough: What the Proxies, Profiles, and Logs Panels Do

Where to Start: Five Panels and What They Cover

Different graphical clients (Clash Verge Rev, Clash Nyanpasu, FlClash, ClashX Meta, Clash for Windows, and others) vary slightly in layout and terminology, but the functional split is essentially the same and can be grouped into five panels: Proxies, Profiles, Rules, Connections/Logs, and Settings. Once you understand what each of these five panels handles, you can cover nearly everything you'll do day to day without hunting through menus item by item.

The relationship between these five panels can be summed up simply: Profiles decides which rule set and node data you're using, Proxies decides which node currently handles outbound traffic, Rules decides which traffic goes through the proxy and which connects directly, Connections/Logs lets you see what's happening right now, and Settings controls how the underlying network parameters are configured. When something goes wrong, figure out which category it falls into first, then head to the matching panel — it's far more efficient than scrolling through every menu.

Proxies: How the Node List and Proxy Groups Work

Proxies is the panel you'll use most often. What it shows is usually split into two layers: proxy groups on top, and the specific nodes inside each group underneath. A proxy group is essentially a rule defined by the proxy-groups field in the subscription config file. The common types are:

• select — manual selection. Whichever node you click is the one used; there's no automatic switching, which suits situations where you already know which route you want.
• url-test — automatic latency testing. The client pings a test URL at a set interval and automatically picks the node with the lowest latency.
• fallback — failover. Nodes are used in order; the client only switches to the next one once the current node becomes unavailable.
• load-balance — load balancing. Requests are distributed across multiple nodes by hash or round robin.

The latency number shown next to each node on the Proxies panel comes from the round-trip time the client measures by periodically requesting a test URL (commonly something like http://www.gstatic.com/generate_204). A lower number usually means a faster response, but it isn't the same as actual download speed — bandwidth and route load affect the experience too. Clicking the "test" icon next to a node manually refreshes its latency immediately, without waiting for the next automatic cycle.

If switching nodes shows the entire proxy group greyed out and unclickable, it's usually because no rule currently references that group, or the active config file hasn't finished loading. In that case, check the Profiles panel first to confirm its status.

Profiles: Subscription Management and Rule Set Loading

The Profiles panel (labeled Profiles or "subscription management" in some clients) manages one or more config files. Each config file is essentially a YAML document that defines the node list, proxy group rules, and routing rules. The three things you'll do most often all happen in this panel:

1. Add a subscription: paste the subscription link, and the client requests it and saves the returned YAML content as a local config file.
2. Update a subscription: re-request the subscription link and overwrite the local file with the latest content — usually with a display of whether nodes changed, remaining traffic quota, and so on.
3. Switch configs: if you've saved multiple subscriptions (say, from two different providers), select here which one is currently active.

One field in the config file that's easy to overlook but matters a lot is mixed-port, which determines the local proxy port the client listens on:

mixed-port: 7890
allow-lan: false
mode: rule
log-level: info

You'll usually find these lines under the "Edit" or "View raw file" option in Profiles. The mode field determines the overall working mode — rule means traffic is routed by rule, global means everything goes through the proxy, and direct means everything connects directly. All three modes usually have a visual toggle in the Profiles panel or at the top of the main window, so you don't need to edit the file by hand to switch between them.

Logs and Connections: What to Check When Troubleshooting

The Logs panel records events that occur while the client is running, split into levels — debug, info, warning, error. When troubleshooting connectivity issues or a site that won't load, set the log level to info or more detailed, then reproduce the problem. You'll usually see the specific error, which is far more useful than restarting the client blindly.

Connections and Logs are easy to confuse. The difference is that Connections shows details of network connections that are currently active or happened recently. Each row typically includes: the target domain or IP, the node used, the rule that matched, upload/download traffic, and connection duration. The most practical use of this panel is checking whether a given app is actually going through the proxy or connecting directly — search for the target domain and see which rule and node it matched to confirm the routing is what you expect.

Neither Logs nor Connections keep history for long; both usually clear when the client restarts. If you need to track an issue over time, watch it as you go rather than counting on reviewing history later.

Settings: TUN Mode, System Proxy, and Launch on Startup

Settings centralizes the switches related to how network traffic is taken over. The three most important ones are:

• System Proxy: when enabled, the client points the system's proxy setting to the local port (the mixed-port mentioned above). Any app that reads the system proxy setting automatically routes through Clash.
• TUN Mode: when enabled, the client creates a virtual network adapter and intercepts all traffic at the network layer, without relying on apps actively reading proxy settings — command-line tools and apps that don't support a system proxy get covered too. It requires elevated permissions (usually admin or root) and can cause a loss of network connectivity if misconfigured, so it's best to get comfortable with System Proxy mode first before trying it.
• Launch on Startup / Silent Launch: determines whether the client runs automatically with the system. Worth enabling if you use it long-term, so you don't have to open it manually every time.

Settings usually also has a LAN sharing toggle (corresponding to allow-lan). When enabled, other devices on the same local network can use this computer as a proxy server — handy for forwarding traffic to devices that can't easily run a client of their own, like smart TVs or game consoles. Keep in mind this widens your exposure, so it's not recommended unless you're on a trusted network.

The Three Spots You'll Use Most Often

Mapping the panels above to actual usage frequency, three entry points stand out as worth remembering:

1. Switching nodes or proxy groups in Proxies — your first move when latency spikes or a node becomes unstable.
2. Updating subscriptions in Profiles — when a provider pushes new nodes or fixes a rule set, you need to manually tap update for it to take effect; clients don't silently auto-update.
3. Checking routing in Connections — when you suspect an app isn't going through the proxy or is taking the wrong route, searching for the target domain here is far more reliable than guessing.

Once you're familiar with these three entry points, you shouldn't need to dig through other menus in daily use. When you come across a button you don't recognize, sort it into one of the panels covered in this guide first, then decide whether you actually need to touch it.
