Surge

1. What is Surge?

Surge is a powerful network toolbox for macOS & iOS. At its core, it works as a local proxy that lets you:

  • 🚀 Bypass network restrictions (via proxy nodes)
  • 🧠 Control traffic routing with rules
  • 🧪 Debug network requests (very strong feature)
  • 🔒 Enhance privacy and security
  • 📱 Manage proxies on Apple devices elegantly

In simple terms: Surge decides “which app / website goes through which proxy (or not)”

2. Surge vs Other Tools (Quick Comparison)

Tool Strength Weakness
Clash Free, popular Limited rule flexibility
Shadowrocket Easy on iOS Less powerful
Surge 🔥 Most powerful Paid, learning curve

If you want fine-grained control and professional-grade rules, Surge is worth it.

3. Supported Platforms

  • ✅ macOS (recommended for beginners)
  • ✅ iOS / iPadOS
  • ❌ Windows / Linux (not supported)

4. Core Concepts (Must Understand)

Don’t skip this section 👇 Surge becomes easy once these are clear.

4.1 Proxy

A proxy is a server that forwards your traffic.

Examples:

  • Shadowsocks
  • Vmess
  • Trojan
  • HTTP / HTTPS

In Surge, proxies are called Proxy or Proxy Group.

4.2 Policy (Proxy Group)

A Policy decides which proxy to use.

Common types:

  • select → manually choose
  • url-test → auto choose fastest
  • fallback → backup system

Example:

ProxyGroup = select, 🇯🇵 JP, 🇺🇸 US, DIRECT

4.3 Rule

Rules decide:

Which traffic uses which policy

Examples:

  • Google → Proxy
  • Local websites → Direct
  • Ads → Block

Rule logic:

IF (condition) → THEN (policy)

4.4 DIRECT / REJECT

  • DIRECT → no proxy, go straight
  • REJECT → block traffic

5. How Surge Works (Big Picture)

App → Surge → Rule → Policy → Proxy → Internet

Surge always follows this order.

6. Installing Surge (macOS)

  1. Download from official site
  2. Install & open Surge
  3. Allow:
    • Network extension
    • VPN permission
  4. Status bar icon appears → Surge is running

7. Configuration File (.conf)

Surge uses one main config file.

Structure:

[General]
[Proxy]
[Proxy Group]
[Rule]

You usually subscribe instead of writing from scratch.

8. Using a Subscription (Most Common)

8.1 Import Subscription

  1. Open Surge
  2. Profiles → Download Profile from URL
  3. Paste your provider’s subscription link
  4. Update profile

That’s it ✅

8.2 Profile Update

  • Surge can auto-update
  • You can also manually refresh

9. Understanding Each Section (With Examples)

9.1 [General]

Basic behavior settings:

[General]
loglevel = notify
dns-server = system

Beginners usually don’t touch this.

9.2 [Proxy]

Defines actual nodes.

Example:

[Proxy]
JP = ss, jp.example.com, 8388, encrypt-method=aes-256-gcm, password=123456

If you use subscriptions → auto generated.

9.3 [Proxy Group]

This is very important.

Example:

[Proxy Group]
Proxy = select, JP, US, DIRECT
Auto = url-test, JP, US, url=http://www.gstatic.com/generate_204

You usually use:

  • One manual group
  • One auto group

9.4 [Rule]

Rules are matched top → bottom.

Example:

[Rule]
DOMAIN-SUFFIX,google.com,Proxy
DOMAIN-SUFFIX,apple.com,DIRECT
GEOIP,CN,DIRECT
FINAL,Proxy

Meaning:

  1. Google → Proxy
  2. Apple → Direct
  3. China IP → Direct
  4. Everything else → Proxy

10. Rule Matching Priority ⚠️

Very important:

FIRST match wins

So:

  • Specific rules → top
  • General rules → bottom
  • FINAL → always last

Simple & Safe Strategy

  • Domestic websites → DIRECT
  • Foreign websites → Proxy
  • Auto node selection

This gives:

  • Good speed
  • Low maintenance

12. Surge Dashboard (macOS)

Key panels:

  • Overview → proxy status
  • Traffic → real-time connections
  • Requests → HTTP debugging
  • Rules → see matched rules

Surge is famous for its Request Inspector

13. Debugging with Surge (Bonus)

You can:

  • View HTTPS requests
  • Modify headers
  • Mock responses
  • Test APIs

This is why many developers love Surge.

14. Common Beginner Mistakes

❌ Putting FINAL too early

❌ Mixing Clash rules directly

❌ Forgetting to enable Surge

❌ No DIRECT rules → slow local access

  1. Use subscription (don’t write config)
  2. Learn:
    • Proxy Group
    • Rule logic
  3. Modify rules
  4. Learn Rewrite & Script (advanced)

16. When Should You Use Surge?

Use Surge if you want:

  • ✅ Precise routing control
  • ✅ Strong debugging
  • ✅ macOS / iOS ecosystem
  • ❌ Not free

17. Summary

  • Surge = professional proxy controller
  • Rules decide where traffic goes
  • Policy decides which node to use
  • Beginners should start with subscriptions
  • Learn rules slowly → Surge becomes addictive 😄
