Project history: Clash, Meta, and mihomo
Clash introduced a configuration-driven proxy kernel that organizes nodes, proxy groups, and rules. Desktop and mobile interfaces were later built around it. After the original project stopped being maintained, community forks continued to evolve, and Clash.Meta was later maintained under the name mihomo. Older guides still use the previous names, so when you find a similar-looking configuration, check which kernel it targets instead of assuming every Clash-named app is the same program.
This history also explains why an older configuration may import successfully but fail at startup with an unsupported field: similar subscription formats do not imply identical feature sets. When consulting technical references, start with protocol support and field definitions. For newer protocols, extended rules, or DNS options, check the target client’s documentation to confirm those features are included.
Open-source community: verify features in the changelog
For example, the MetaCubeX/mihomo source repository’s commits, release notes, and issue discussions can help you track feature changes. If connections behave unexpectedly, check for known compatibility issues before updating the kernel or changing the configuration. Stars, download counts, and interface design are not substitutes for specific compatibility information, and this site does not rank clients by performance.
When reporting an issue, include your operating system, client name, connection mode, reproduction steps, and relevant logs. Remove subscription URLs, node credentials, and other sensitive information. A minimal, reproducible report helps the community more than a complete private configuration. Before using someone else’s rule file, check what it covers, how often it is updated, and its license; do not assume an outdated ruleset is a universal solution.
Graphical clients: interface and execution layers
Graphical clients typically offer subscription management, a system proxy toggle, connection lists, and log viewing. The kernel reads the final configuration and handles connections. A setting visible in the interface may not appear unchanged in an exported file; conversely, the client may regenerate manually edited fields at startup. When troubleshooting, inspect the configuration actually in use and distinguish the original subscription, local overrides, and final merged result.
For a first setup, start by comparing Clash Plus, then choose another client based on your platform needs. If you need more override options, service management, or interface customization, compare features in the Client Comparison guide instead of choosing by name alone. On mobile, also consider background operation and battery use; on desktop, focus on system proxy settings, permissions, and compatibility with other network tools.
Updates: check the app, kernel, and subscription separately
App updates may change the interface or service components; kernel updates may change protocol support and configuration validation; subscription updates usually replace node or rule data. Each addresses a different issue. If a subscription update fails, check whether the link is valid and reachable. If configuration parsing fails, inspect the fields and format. If a connection is established but access fails, check matched rules, DNS, and the outbound route.
Before upgrading, save a working configuration and local overrides, then read the release notes. After updating, repeat your usual tests. Change one major variable at a time to tell whether a result came from the app update or a configuration change. When rolling back, check data format compatibility so settings generated by a newer client can still be read by the older setup. For devices in regular use, record the installation source and service startup method to make recovery easier.
