Why Rulesets Matter More Than Raw Bandwidth
Clash-family clients do not merely forward packets. In rule mode, they evaluate each connection against an ordered list: domain keywords, full-domain matches, suffix rules, IPCIDR ranges, GEOIP buckets, and finally a fallback such as MATCH. A mis-tuned rule file can send domestic CDNs through your overseas tunnel—adding latency for no benefit—or leave critical hostnames on DIRECT when you expected them to follow the proxy group. That is why experienced users spend as much time on rule providers as on subscription URLs.
Both ACL4SSR and Loyalsoldier publish collections of lists—often consumed as rule-providers with behavior: classical or domain semantics depending on the file—plus opinionated templates that wire those lists into proxy groups, DNS, and fallback chains. The comparison below is therefore about defaults and maintenance philosophy, not a single YAML file you can paste once and ignore forever.
What a “Rule Provider” Actually Does in Meta Core
In Mihomo-compatible YAML, a rule-provider entry points to a remote URL (or local file) that the core downloads on a schedule. At runtime, the engine expands those lists into matchable data structures. Larger lists increase memory use and startup time; smaller lists are easier to reason about but may miss edge-case domains your daily apps actually hit.
Practical takeaway: when someone says “I use ACL4SSR” or “I use Loyalsoldier,” they usually mean a bundle of remote lists plus a template that references them. Swapping brands without reading which lists are enabled is how you end up with duplicated GEOIP passes, conflicting ad-block sections, or DNS that never resolves the way your rules assume. If you are still converting raw provider subscriptions into YAML, see our Subconverter complete guide first, then return here to tune routing.
ACL4SSR: Community Roots and China-Centric Defaults
ACL4SSR grew from a long-running community effort to categorize domains for users who need domestic services on direct paths while sending international or “sensitive” destinations through a proxy. The project name is shorthand people remember; what matters operationally is the shape of its lists: extensive coverage of China mainland sites, streaming and CDN patterns, and variants that add or remove ad-blocking and privacy-focused extras.
Typical selling points for ACL4SSR-style bundles include granular splits—think domestic video platforms, music apps, and bank portals—so that day-to-day browsing does not unnecessarily traverse the tunnel. That can reduce jitter on local content and avoid surprising geolocation mismatches. The trade-off is complexity: more lists mean more interactions with DNS fake-IP settings, fallback groups, and update ordering. Beginners sometimes copy a “full” profile on a laptop that only has eight gigabytes of RAM and then wonder why the dashboard feels heavy at startup.
Loyalsoldier: Broad Coverage and Opinionated Releases
Loyalsoldier maintains a widely mirrored set of rule lists and related data files that many Meta users treat as a stable upstream for GEOIP, domain, and IP-based routing. The project is often praised for consistency in how releases are tagged, how files are named, and how large lists are split so clients can subscribe selectively. If your mental model is “I want GEOIP and common domain buckets maintained by someone who follows upstream changes,” Loyalsoldier is frequently the first search result.
Where Loyalsoldier shines is breadth: comprehensive coverage of global services, clear separation between direct and proxy paths when you adopt the recommended templates, and documentation that explains which file does what. Where users must stay alert is the same as with any large project: your threat model is not identical to the maintainer’s. A default that maximizes convenience for a developer in one region may send traffic differently than you expect for gaming, banking, or corporate SaaS—always diff the template before you deploy it on production hardware.
Maintenance Cadence and What “Stale” Really Means
Both ecosystems depend on upstream changes: CDNs add new hostnames, apps migrate to different API endpoints, and regulators change how services are reachable. A ruleset that is “outdated” rarely fails outright—it misroutes: you see slow loads, captcha loops, or intermittent TLS failures because a domain now resolves to a new edge cluster that your GEOIP or domain rule no longer recognizes.
Healthy practice is to treat rule updates like any other dependency: set a sane refresh interval in your client, pin to URLs you trust, and keep a local backup YAML when you experiment. When a provider changes subscription format, you update Subconverter; when the internet shifts, you update rule providers. If you run a desktop GUI such as Clash Verge Rev, combine this article with our Windows installation and setup guide so profile refresh and logging are already comfortable before you chase advanced routing.
Reality check: No remote list knows your LAN, your employer’s split DNS, or your ISP’s captive portal. Keep short custom rules at the top of your chain for those exceptions.
Routing Philosophy: Domestic Direct vs Global Buckets
ACL4SSR-flavored templates often emphasize fine-grained domestic direct routing for users in or near China mainland, minimizing unnecessary international hops for local CDNs. Loyalsoldier-flavored templates frequently appeal to users who want well-labeled global lists and predictable GEOIP splits without assembling every niche domain by hand. Neither approach is universally “better”; they optimize for different pain points.
When you evaluate either stack, ask blunt questions. Do you need streaming services split by region? Do you want advertisement and tracker domains dropped or routed separately? Are you running TUN mode with full-device capture? TUN magnifies routing mistakes because more apps suddenly obey the same policy—if that is on your roadmap, read the complete TUN mode setup guide for Clash Verge Rev alongside rule tuning so DNS hijack and stack order stay coherent.
Performance, Memory, and Match Order
Every domain and IP rule consumes CPU cycles during matching. Extremely large classical lists are powerful but not free: on low-power devices, prefer slim bundles and fewer redundant providers. Meta core is efficient, yet physics still applies—duplicate passes over GEOIP, overlapping domain sets, and aggressive ad lists can amplify startup time.
Order matters. Rules execute top-down; the first win stops evaluation for that connection. Templates that interleave user-defined inserts with remote providers give you a place to pin must-direct intranet routes before broad GEOIP catches. If you import multiple third-party bundles simultaneously, watch for shadowed rules: later duplicates rarely execute, but they still consume memory.
Which Baseline Should You Start From?
Use ACL4SSR-oriented bundles when your daily workload is heavily mixed between China mainland services and international SaaS, and you want community-maintained splits for common domestic apps. Use Loyalsoldier-oriented bundles when you prioritize broad GEOIP coverage, clear file boundaries, and a template ecosystem that many forks and converters already expect.
Mixed strategy is common: keep one project’s GEOIP data while borrowing another’s domain lists for a specific vertical—games, streaming, or developer tooling—then document what you changed. The moment you fork without notes, future you will not know why a single hostname behaves differently on laptop versus phone.
Security: Only fetch rule providers over HTTPS from sources you trust. Treat rule URLs like configuration secrets—paste them carefully and rotate if leaked in a screenshot.
DNS, FakeIP, and Why Rules Look “Wrong” After Lunch
Routing rules operate on names and IPs produced by your DNS pipeline. If FakeIP is enabled, some domain rules behave differently than on a plain resolver; if DoH upstreams fail, you might match fallback IPs that do not align with GEOIP expectations. Before you blame ACL4SSR or Loyalsoldier for a “bad rule,” confirm which resolver answered the query and whether the client logged the final outbound choice.
Align DNS mode with your template: conservative users often start with straightforward resolver settings, validate connectivity, then enable more advanced split-horizon setups.

Open Source, Mirrors, and Where Installers Belong
Both ACL4SSR and Loyalsoldier publish their work in public repositories so you can audit changes, file issues, and understand how lists are generated. That transparency is valuable and distinct from client distribution: when you need a verified desktop or mobile package, prefer the site’s download flow first, then visit upstream repositories for source code, changelogs, and collaboration—exactly the same separation we recommend in other long-form guides on this blog.
Summary
ACL4SSR and Loyalsoldier are not mutually exclusive absolutes—they are two mature answer keys for the same exam: how to split traffic intelligently inside Clash Meta. ACL4SSR-flavored stacks often excel at China-centric nuance; Loyalsoldier-flavored stacks often excel at breadth and predictable structure. Pick based on your region, device limits, and willingness to maintain custom overrides, then measure outcomes with logs instead of forum rumors.
Compared with juggling one-off snippets copied from outdated threads, a coherent Meta-powered client with sane defaults and observable rule hits feels calmer day to day—fewer mysteries when a site suddenly loads from the wrong egress, and a clearer path when you need to tweak just one line.
