Selecting the right web host for your Tor relay

If you’re reading this guide, it’s likely that you’ve already gone through our article on why you should run a Tor relay and are considering taking the next step. Running a Tor relay is a commendable decision, supporting a global network that upholds privacy and freedom of information. This guide is designed to walk you through the practical aspects of setting up a Tor relay, from choosing the right type of relay to selecting a web host and understanding the ongoing responsibilities involved. Whether you’re new to this or have some experience, this guide aims to provide you with the essential information to make informed decisions and contribute effectively to the Tor network.

Types of Relays

When you’re considering setting up a Tor relay, it’s important to first understand the different types of relays available. There are three main kinds: Bridge, Middle, and Exit Relays. Bridge Relays are great if you’re concerned about being blocked, as they’re less likely to be flagged by networks or governments and aren’t listed publicly. Middle Relays are the connectors within the Tor network, handling encrypted traffic but not serving as entry or exit points. Then there are Exit Relays, which are vital since they enable traffic to move from the Tor network to the public internet. However, they’re a bit more complex because of their sensitivity to potential misuse and the legal implications that come with it. Each type has its unique role and implications, so choosing the right one for your needs and capabilities is key.

Researching the right host

When selecting a web host for your Tor relay, it’s crucial to thoroughly review their Terms of Service. This includes being transparent about your activities. It’s a common mistake to try and hide that you’re running a Tor relay, but honestly, it’s not worth it. Most hosting services will eventually figure it out, and if you haven’t disclosed this upfront, you might face service termination. So, clear disclosure is key. Also, not all hosts are Tor-friendly. Some explicitly allow Tor relays, while others prohibit them. Therefore, make sure to confirm that the host’s terms of service are compatible with running a Tor relay. This step is vital to avoid any future complications and ensure a smooth operation of your relay.

A note on research

Conducting thorough research is a crucial step in selecting the right web host for your Tor relay. Start by searching online for experiences and recommendations from other Tor relay operators. You can do this by looking up “{prospective host} Tor relay” to gather insights on how different hosts have worked out for them. This can give you a real-world perspective on what to expect. Additionally, make use of the Tor Metrics website. Here, you can check the host’s Autonomous System Number (ASN) to see how many other Tor relays they are hosting. A higher number of relays under a particular ASN often indicates a Tor-friendly environment. This kind of research can provide valuable information and help you make an informed decision about which web host will best meet your needs for running a Tor relay.

Don’t try this at home

A common question people ask: Why not run a relay at home? Technically, you can, but it’s generally not advisable due to several critical reasons. Running a relay at home exposes you to various privacy, security, and legal issues. Most Internet Service Providers (ISPs) have very low tolerance for abuse/misuse, leading to potential service termination. This is a significant risk, especially if your ISP is the only available option in your area. Losing your internet service due to policy violations could be a severe setback.

However, there is a safer alternative for those keen on contributing from home: the Snowflake browser add-on. Snowflake allows you to act as a bridge relay, where your browser simply facilitates the passage of encrypted traffic. The key advantage here is that your IP address isn’t publicly listed, significantly reducing the risks associated with running a full relay from home. This makes Snowflake a viable option for contributing to the Tor network without the extensive implications of hosting a traditional relay.

Choosing your specs

When assessing web hosts for your Tor relay, there are several key features to consider. First, think about the cost. Set a clear budget because running a Tor relay, especially an exit relay, can demand a more robust hosting plan. Then, there’s bandwidth, a critical factor since Tor relays need a lot of it. Look for hosts that offer generous or even unmetered bandwidth to ensure smooth operation. Don’t forget about the hardware specs, either. Your server should have the necessary CPU and RAM to manage the traffic you expect to handle. Lastly, consider the location of the server. The geographic location isn’t just about performance; it can also have legal implications, particularly for exit relays. Each of these aspects plays a vital role in ensuring that your Tor relay runs efficiently and within legal boundaries.


It’s crucial to stress that running a Tor relay is an active commitment, not a one-time setup. You must implement a firewall and consistent monitoring to prevent misuse of your relay. This is not a “set and forget” scenario; think of your relay as a complex system needing regular oversight.

Staying informed is equally important. Keep abreast of legal and policy changes in your host’s location related to Tor relay operation, and stay updated with Tor network news. Regular updates and vigilant management are essential for the secure and effective operation of your Tor relay. It’s a continuous commitment that requires your attention and care.

Engage the community!

It’s also vital to highlight the importance of participating in the Tor community. Engaging with this community provides an invaluable opportunity to seek guidance and support. Experienced relay operators within the community can offer a wealth of insights and advice. Their knowledge and experience can be incredibly helpful, especially when navigating the complexities of setting up and maintaining a Tor relay. By actively participating in these community discussions, you can learn best practices, get tips on troubleshooting, and stay informed about the latest developments in the Tor network. This engagement is a crucial part of running a successful and secure Tor relay.
