code-server is used by developers at Azure, Google, Reddit, and more to give them access to VS Code in the browser.
NOTE: If you get stuck or need help, file an issue, tweet (@coderhq) or email.
This document pertains to Coder specific implementations of VS Code. For documentation on how to use VS Code itself, please refer to the official documentation for VS Code
It takes just a few minutes to get your own self-hosted server running. If you've got a machine running macOS, Windows, or Linux, you're ready to start the binary which listens on port 8443
by default.
- Visit the releases page and download the latest cli for your operating system
- Double click the executable to run in the current directory
- Copy the password that appears in the cli
- In your browser navigate to
localhost:8443
- Paste the password from the cli into the login window
NOTE: Be careful with your password as sharing it will grant those users access to your server's file system
- When you visit the IP for your code-server, you will be greeted with this page. Code-server is using a self-signed SSL certificate for easy setup. To proceed to the IDE, click "Advanced"
- Then click "proceed anyway"
code-server --help
code-server can be ran with a number of arguments to customize your working directory, host, port, and SSL certificate.
Usage: code-server [options]
Run VS Code on a remote server.
Options:
-V, --version output the version number
--cert <value>
--cert-key <value>
-e, --extensions-dir <dir> Set the root path for extensions.
-d --user-data-dir <dir> Specifies the directory that user data is kept in, useful when running as root.
--data-dir <value> DEPRECATED: Use '--user-data-dir' instead. Customize where user-data is stored.
-h, --host <value> Customize the hostname. (default: "0.0.0.0")
-o, --open Open in the browser on startup.
-p, --port <number> Port to bind on. (default: 8443)
-N, --no-auth Start without requiring authentication.
-H, --allow-http Allow http connections.
-P, --password <value> Specify a password for authentication.
--disable-telemetry Disables ALL telemetry.
--help output usage information
Use code-server -d (path/to/directory)
or code-server --data-dir=(path/to/directory)
, excluding the parentheses to specify the root folder that VS Code will start in.
By default, code-server will use 0.0.0.0
as its address. This can be changed by using code-server -h
or code-server --host=
followed by the address you want to use.
Example:
code-server -h 127.0.0.1
You can have the server automatically open the VS Code in your browser on startup by using the code-server -o
or code-server --open
flags
By default, code-server will use 8443
as its port. This can be changed by using code-server -p
or code-server --port=
followed by the port you want to use.
Example:
code-server -p 9000
Disable all telemetry with code-server --disable-telemetry
.
To encrypt the traffic between the browser and server use code-server --cert=
followed by the path to your .cer
file. Additionally, you can use certificate keys with code-server --cert-key
followed by the path to your .key
file.
Example (certificate and key):
code-server --cert /etc/letsencrypt/live/example.com/fullchain.cer --cert-key /etc/letsencrypt/live/example.com/fullchain.key
Example (if you are using Letsencrypt or similar):code-server --cert /etc/letsencrypt/live/example.com/fullchain.pem --cert-key /etc/letsencrypt/live/example.com/privkey.key

Nginx is for reverse proxy. Below is a virtual host example that works with code-server. Please also pass --allow-http. You can also use certbot by EFF to get a ssl certificates for free.
server {
listen 80;
listen [::]:80;
server_name code.example.com code.example.org;
location / {
proxy_pass http://localhost:8443/;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection upgrade;
proxy_set_header Accept-Encoding gzip;
}
}
Example of https virtualhost configuration for Apache as a reverse proxy. Please also pass --allow-http on code-server startup to allow the proxy to connect.
<VirtualHost *:80>
ServerName code.example.com
RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) ws://localhost:8443/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) http://localhost:8443/$1 [P,L]
ProxyRequests off
RequestHeader set X-Forwarded-Proto https
RequestHeader set X-Forwarded-Port 443
ProxyPass / http://localhost:8443/ nocanon
ProxyPassReverse / http://localhost:8443/
</VirtualHost>
Important: For more details about Apache reverse proxy configuration checkout the documentation - especially the Securing your Server section
