title: Import Your Old Caddy Setup description: Guide to importing existing Caddyfile configurations into Charon. Migrate your reverse proxy setup without starting from scratch.

Import Your Old Caddy Setup

Already using Caddy? You can bring your existing configuration into Charon instead of starting from scratch.

What Gets Imported?

Charon reads your Caddyfile and creates proxy hosts for you automatically. It understands:

• ✅ Domain names
• ✅ Reverse proxy addresses
• ✅ SSL settings
• ✅ Multiple domains per site

How to Import

Step 1: Go to the Import Page

Click "Import Caddy Config" in the sidebar.

Step 2: Choose Your Method

Option A: Upload a File

• Click "Choose File"
• Select your Caddyfile
• Click "Upload"

Option B: Paste Text

• Click the "Paste" tab
• Copy your Caddyfile contents
• Paste them into the box
• Click "Parse"

Step 3: Review What Was Found

Charon shows you a preview:

Found 3 sites:
✅ example.com → localhost:3000
✅ api.example.com → localhost:8080
⚠️  files.example.com → (file server - not supported)

Green checkmarks = will import Yellow warnings = can't import (but tells you why)

Step 4: Handle Conflicts

If you already have a proxy for example.com, Charon asks what to do:

• Keep Existing — Don't import this one, keep what you have
• Overwrite — Replace your current config with the imported one
• Skip — Same as "Keep Existing"

Choose what makes sense for each conflict.

Step 5: Click "Import"

Charon creates proxy hosts for everything you selected. Done!

Example: Simple Caddyfile

Your Caddyfile:

blog.example.com {
    reverse_proxy localhost:3000
}

api.example.com {
    reverse_proxy https://backend:8080
}

What Charon creates:

• Proxy host: blog.example.com → http://localhost:3000
• Proxy host: api.example.com → https://backend:8080

What Doesn't Work (Yet)

Some Caddy features can't be imported:

File Servers

static.example.com {
    file_server
    root * /var/www
}

Why: Charon only handles reverse proxies, not static files.

Solution: Keep this in a separate Caddyfile or use a different tool for static hosting.

Path-Based Routing

example.com {
    route /api/* {
        reverse_proxy localhost:8080
    }
    route /web/* {
        reverse_proxy localhost:3000
    }
}

Why: Charon treats each domain as one proxy, not multiple paths.

Solution: Create separate subdomains instead:

• api.example.com → localhost:8080
• web.example.com → localhost:3000

Environment Variables

{$DOMAIN} {
    reverse_proxy {$BACKEND}
}

Why: Charon doesn't know what your environment variables are.

Solution: Replace them with actual values before importing.

Import Statements

import snippets/common.caddy

Why: Charon needs the full config in one file.

Solution: Combine all files into one before importing.

Tips for Successful Imports

1. Simplify First

Remove unsupported directives before importing. Focus on just the reverse_proxy parts.

2. Test with One Site

Import a single site first to make sure it works. Then import the rest.

3. Keep a Backup

Don't delete your original Caddyfile. Keep it as a backup just in case.

4. Review Before Committing

Always check the preview carefully. Make sure addresses and ports are correct.

Troubleshooting

"No hosts found"

Problem: Your Caddyfile only has file servers or other unsupported features.

Solution: Add at least one reverse_proxy directive or add sites manually through the UI.

"Parse error"

Problem: Your Caddyfile has syntax errors.

Solution:

1. Run caddy validate --config Caddyfile on your server
2. Fix any errors it reports
3. Try importing again

"Some hosts failed to import"

Problem: Some sites have unsupported features.

Solution: Import what works, add the rest manually through the UI.

After Importing

Once imported, you can:

• Edit any proxy host through the UI
• Add SSL certificates (automatic with Let's Encrypt)
• Add security features
• Delete ones you don't need

Everything is now managed by Charon!

What About Nginx Proxy Manager?

NPM import is planned for a future update. For now:

1. Export your NPM config (if possible)
2. Look at which domains point where
3. Add them manually through Charon's UI (it's pretty quick)
