Step-by-step Urbit install guide for users with no prior technical knowledge. You will have a set it and forget it Urbit server accessible from any web browser in about 1 hour's time, on a $10/mon VPS. This is the recommended best practice install for Urbit unless you maintain your own home server.
This guide uses Digital Ocean as the cloud provider for its easy to read user interface, but any VPS service can be used.
Note: $10/mon is less than what you'd pay for a full-service Urbit hosting provider (~$12-15/mon), which I don't currently recommend due to their unreliability and limited data control.
You can also try out Urbit at no-cost on your local machine easily on Windows/OSX/Linux with Port, but this setup you'll have to setup port forwarding if you want to access your server from other devices. It's not ideal unless you run your own always-on home server.
What is Urbit?
Urbit is famously hard to explain because it's extremely ambitious, a fundamental reimagination of the computer according to contemporary principles. The short answer tagline is Urbit is an open source platform for sovereign personal computing, or alternatively, a new internet from first principles.
In practice, Urbit today is a social network supporting groupchat, shared journals, personal blogs and native crypto integration that is fully decentralized and respectful of data self-ownership & privacy by design.
Urbit is accessed from any standard web browser, but due to its decentralized design, you can only get online by running your own Urbit server which doubles as your Urbit account, which this guide will walk you through.
You can read a more in-depth explanation here: Urbit for Normies.
Step 1: Setup a Virtual Private Server
This guide will use Digital Ocean due to its clear user interface and web console. If you don't have any technical background or are on Windows without a terminal setup, it's recommended to use it.
If you'd like to use your own VPS provider, Urbit's recommended specifications are 2GB RAM and 5-50GB storage over a year of use. Ubuntu 20.04 is a standard environment for install. If you do this, skip forward to 1b. Access the VPS to continue.
1a. Create a Digital Ocean droplet
Create an account on Digital Ocean.
Create a droplet (DO's term for a virtual server) with the following settings:
- Image: Ubuntu 20.04 x64
- CPU: Regular Intel with SSD
- Plan: $10/mo - 2GB RAM / 1 CPU, 50GGB SSD, 2TB Transfer
- Add block storage: Skip
- Datacenter Region: Choose the region closest to you.
- VPC Network: Skip
- Additional Options: Skip
- Authentication: SSH keys. Click
New SSH Keyand add your SSH key. If you don't have one, follow the instructions Digital Ocean gives you to create one.
- How many Droplets: 1
- Choose a hostname: This will be the hostname of the box you ssh into (can be whatever you want, I used my Urbit planet name).
- Add tags: None
- Project: It'll select your default.
- Backups: Optional (it costs a little extra, but I have it enabled for peace of mind).
All done, click
Create Droplet to move forward.
1b. Access the VPS
If you're on Digital Ocean, you can access the console directly from the web interface by clicking the
Access console, then
Launch Droplet Console
If you're running a different VPS or prefer to operate from your computer terminal, ssh using your IPv4 address:
$ ssh root@your_server_ip.
If you set a passphrase on your ssh key, you'll be asked for it. If not, you should automatically be logged in.
Step 2: Configure the Droplet and Install Urbit
Before we install Urbit, we'll setup a firewall on the droplet and open port 34543 for Urbit to use. Paste the following commands:
sudo ufw allow OpenSSH sudo ufw allow www sudo ufw allow https sudo ufw allow 34543/udp sudo ufw enable
Next we'll allocate swap space on the server for Urbit. Paste the following commands:
sudo fallocate -l 2G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile sudo cp /etc/fstab /etc/fstab.bak echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
Now we're ready to install Urbit on your server. This part is actually very easy - just paste and run all the following commands into your console:
mkdir ~/urbit cd ~/urbit wget --content-disposition https://urbit.org/install/linux64/latest tar zxvf ./linux64.tgz --strip=1 cd .. ~/urbit/urbit
After the install completes, you will see a block of output beginning with the line confirm its success:
Urbit: a personal server operating function
Step 3: Obtain a planet
An Urbit ID is needed to enter the system. Planets are persistent ID's available for purchase, but Comets are available as free non-persistent "guest" ID's for trying out the system.
If you'd like to skip getting a planet for now and jump immediately into Urbit, you can boot a comet by running the following command, then skipping to Step 5: Enter Urbit Landscape:
~/urbit/urbit -c mycomet
As of October 2021, Urbit planets are going for a historical high average of ~$100-150 USD, though for a long time they were sold for $10-20. You will also need another ~$50-150 in Ethereum for the gas fees associated with purchasing the planet as well as initializing its network keys.
3a. Purchase a Planet
Planets need to be purchased as an Ethereum ERC-720 NFT. If you have never purchased Ethereum NFT's and don't have an Ethereum Web3 wallet, follow these instructions to be setup with MetaMask. If you already own a planet, skip to 3b. Obtain your Planet's Keyfile.
Planets can be bought with Ethereum from NFT marketplaces, such as the following:
3b. Obtain your Planet's Keyfile from Bridge
We need to authenticate your planet to obtain its keyfile to upload to your Urbit server.
Goto bridge.urbit.org. You will see the following disclaimer, check the box and hit
Metamask, Mnemoic, Hardware Wallet...
Select whichever Ethereum wallet provider you use, and connect your wallet to authenticate ownership over the planet NFT.
You will see a welcome message with your planet's badge and master key. Do not share this master key with anyone, as it holds access to your planet. Click on
OS, Urbit OS Settings to continue.
Initialize Networking Keys
Set Networking Keys then
Note: You will need to pay about 0.002 ETH to submit the transaction.
Once the transaction is complete, the "Download Arvo Keyfile" button should be available for you to press. You should receive a
.key file that contains the secret needed to boot your planet. Hold onto this file.
Step 4: Configure your Planet
Copy the contents of the keyfile, then return to your console and enter the following to create a new file on your server:
Paste the contents of the keyfile and press
enter to save and exit.
Alternatively, if you're already using your own terminal and ssh, you can transfer the file by scp:
scp <local path to keyfile> root@<droplet ip address>:
Next, enter the following command to boot your planet (don’t include the tilde in your planet’s name, i.e.
~/urbit/urbit -w <planet name> -k keyfile.key
It will take 10-20 minutes to boot while commands spew out. You'll know the boot is complete when the prompt shows:
Dojo is the Urbit terminal. Once it completes, enter the following to mount the filesystem:
Now shut down your planet with
The keyfile is not needed to re-start your planet once it's been successfully booted, so we'll delete it for security with the following command:
shred -vzn 3 keyfile.key rm keyfile.key
Next, setup a screen session:
screen -S urbit
This will start a screen session so Urbit runs continuously in the background, we can now start up the Urbit ship from the
urbit directory in this session:
~/urbit/urbit -p 34543 <planet name>
+code to generate an Access key.
This code is essentially your ship's password, copy it down for use in the next step. You can also always find it on the Bridge, under
All set, now we can disconnect from the screen session and leave the ship running with
Step 5: Enter Urbit Landscape
Landscape is the default graphical interface of Urbit, accessed by your standard web browser. Now that your Urbit server is running, you can access it directly by going to your Droplet's IPv4 address as if it was a url.
You'll be greeted with a login screen, with your Access key needed to continue. Paste the code from the previous step into the Access Key field (if you lost it, just go back to the console and enter
The first boot will take a few minutes as it sets up your system.
Once it's done, you'll be greeted with a dashboard of apps:
Click into Groups for the main landscape dashboard:
Congratulations, you're officially running Urbit. Current functionality includes group text chats & blogging. You will be able to access this at any time, from any web browser, by navigating to your virtual server's IP address.

Part 2: Pointing Urbit to a domain
Setting up your own domain will make accessing your Urbit a lot easier, giving a memorable url you can navigate to rather than an IP address. It'll also allow you to secure things with an SSL certification.
You have a couple options:
A. Provide your own domain
B. Obtain a free subdomain through Urbit (will take a few days, but setup is automated)
A. Provide your own Domain
If you don't already have a domain, you will need to purchase one. A standard .com domain is ~$12/year.
If you want to use a free subdomain, skip to A1a. Free Subdomain with a Third-party, however you'll need to log in every 6 months to keep it registered.
There are a lot of domain name registrars you can use, this guide suggests Google Domains.
From there you can search for and register a domain that you like. You can also point to a subdomain of any domain you own, but you will need to have the nameservers pointing to the cloud server.
A1. Configure domain name servers to Digital Ocean
Once you've registered your domain, you'll need to configure it to point to your VPS name servers. For Digital Ocean, that's:
The steps to do so vary slightly by domain providers, but for Google Domains, just navigate to DNS:
Custom Name Servers:
And enter the 3 digital ocean name servers and hit save:
Now that you've updated the DNS records you can add the domain to your Digital Ocean droplet. Skip to A2: Point Digital Ocean to your Domain.
A1a. Free Subdomain with a third-party (Afraid.org)
You can setup a free subdomain with afraid.org, however you will need to make sure to login once every 6 months for it to remain active. Simply create an account, then goto registry on the left side, and pick a domain to register under.
Set the Type to NS, choose your subdomain and set the destination to
In this example, your domain would be
Now that you've setup your domain, continue to A2: Point Digital Ocean to your Domain.
A2. Point Digital Ocean to your Domain
Back on Digital Ocean, go to
Create > Domains/DNS
Enter your domain and hit
Add a domain
Click on that domain and add an A record that directs to the IP of your droplet (found on your droplet's page).
It will automatically take you to the Create new record page.
hostname, enter your subdomain, or if you intend to make it main domain, enter
Will Direct To, select your Digital Ocean droplet. Change
TTL to 60 to update quickly, then hit
A3. Obtain an SSL Cert
Now we run a few commands in Dojo to request an SSL cert for your domain through Let's Encrypt.
Navigate back to your Urbit page, and click the Dojo app. This is the Urbit terminal.
Enter the following command, which will run the acme agent that requests an SSL certification, replace
tld with whatever your top-level domain is e.g.
:acme &path /tld/domain/subdomain
Subdomain is optional and that part of the command should be omitted if you are not using a subdomain.
Check your domain, if everything is working properly you should see your login page. Log in with your access key like normal and you should enter Urbit Landscape. You can now access from this domain whenever you want.
B. Obtain a subdomain from Tlon
Tlon Corporation offers a free subdomain service under
arvo.network, however it will take a few days to register.
On your main Urbit, select the terminal:
Enter the following command, replacing
.126.96.36.1990 with your IP address (include the period preceding the numbers):
-dns-address &dns-address [%if .188.8.131.520]
Let it run, and once you receive
confirmed access via ship.arvo.network, you'll be able to navigate to your
sampel-palnet with your ship name) to access Urbit.
Part 3: Configuring S3 storage for your urbit
S3 (Simple Storage Service) storage is essentially your Urbit server's hard drive for any files larger than text. You'll need it configured if you'd like to share images, such as in chat or notebooks.
The official S3 is run by Amazon, but other providers run compatible services – Digital Ocean's is called Spaces, and it is built to be interchangeable with AWS S3’s API. You don’t need to be running your ship on Digital Ocean to use Spaces with it, though the provider you use does have to support Signature Version 2.
Step 1: Create a Space
On Digital Ocean, goto Create and find
Spaces in the dropdown:
Choose a datacenter closest to your location. Leave CDN disabled.
Leave file listing on
Restrict File Listing
Give it a unique name and select your project.
Create a Space.
After it sets up, you'll be redirected to the spaces page. Goto settings.
CORS Configurations and click Add.
We want to add three rules – in the Origin box, put a
*, then check
Finally, click ‘Add header’, and add another
We have one last step before we enable this on our ship – getting our API keys.
In the main navigation bar on the left, look for
API towards the bottom and select it:
Scroll down and you’ll see
Spaces access keys; select
Generate new key.
Give it a name and hit the checkmark.
It will give you two lines of random text – the top one is your access key, and the bottom is your secret key.
Think of them as your username and password; do not share them or post them publicly, unless you want strangers abusing your storage.
Step 2. Ship configuration
Now, let’s tell our ship how to use it.
Open Landscape, click your profile at the top right corner, and select
Access Key ID and your
Secret Access Key.
Now go back to Digital Ocean and navigate to Spaces from the sidebar. Scroll down to the
Endpoint section and copy the provided url.
Add it to under
s3 Buckets, click add new bucket and add your Space name without the rest of the url:
Hit submit and then click options and select
That's it, you're all set with storage.
Alternatively, you can enter your credentials in the command line. Let’s proceed to our dojo (CLI or Landscape). Enter the following commands, replacing the variables in single quotes with your own details:
urbit - sampel-palnet ~sampel-palnet:dojo> :s3-store|set-endpoint 'ams3.digitaloceanspaces.com' ~sampel-palnet:dojo> :s3-store|set-access-key-id 'ACCESSKEY' ~sampel-palnet:dojo> :s3-store|set-secret-access-key '5eCrEtK3Y/8L4H8L4H' ~sampel-palnet:dojo> :s3-store|set-current-bucket 'bucketname'
