Server Manager web page launched today. It writes data into the tshock json configuration files. Since there are so many options, a select few have been chosen to modify. A batch of the server configurations and then server side characters can be modulated with this.

Carbuncle v2.2.320 how-to document -- this was put together to go over the basics of the latest version and how the program functions. It is an .rtf file with screenshots.
There is also a website with the same data: here.

Dec. 30th, 2020
Using the recently designed server hosting tool and chat client, Carbuncle v2, server hosting now has a platform to serve those interested in remote hosting. The features include world seeds, TShock, and world uploading. The servers will be free for the month of January. They are hosted on a high speed connection that should not cause much latency.

April 5th, 2019
In case you've tried to start a server since the last news update, it was not functioning properly. This has recently been altered, and should now work, granted the limit for servers has not been reached.

March 11th, 2019
Servers are now hosted at a remote service which may be much more reliable. Other revisions have been made as well. tServer Host is a new addition to, and is run by, Circle Prefect.

Jan. 23rd, 2018
Moved server hosting to a more reliable location, and with better hardware.

Aug. 30th, 2017
Finished fixing most of the bugs in the server automation software. Can supply only ONE server as of now, and it would be free.

The forum post has been ported over here from Terraria Online, and appropriately modified.

Server Downtime, and Plans

For support or further information:

I'm upgrading the server hardware so I can provide more servers -- currently hosting is down until that occurs, which will be in only a couple of days. Afterwards, I could provide 6 more servers for a total of seven.

Hey I'm interested in using a free server, if one is available. However, for some reason I am not able to click on the image header and therefore can not register for a server. Perhaps you could help me out?

Edit: Nevermind, I think I figured it out. :)


I've since made the image header a direct link to the website. For some reason, I overlooked that.

Found new hosting for servers because the previous one proved to be unstable. The new hardware and speeds are far superior, so lag should only be an issue if you reside far away from the server location.

You can, again, fill out the form on the website for free servers 16 players and under (limited availability). May push the limit of players higher in the coming weeks if needs demand it.



Update and News:
Since the previous hosting setup was inefficient and altogether unstable, a move has been made to host servers at a remote location virtually. The setup is in testing, and so during this phase, a limited number of servers are available through the form at The "tServer Host" domain is a recent addition to Circle Prefect.

Among other things such as pending updates to this and that, the free service will last until testing phase is complete. This is estimated at around one month.

For support, the contact service is available.

Information on the free server offer:
In case anyone has tried within the last month to start a server, well, it was working maybe a fraction of that time frame. There was some things to work out in the mean time. But as of now, that should be completely resolved.

Do know, if the servers reach capacity for the duration of the testing offer, then if anyone applies, that attempt will be denied.

The current offer for free servers is going to last until the end of April, and the server uptime until closure will last another one month. At that point, the offer for free servers will have been done.

Again, this offer is only temporary.

World uploading:
At this point, world uploading services for servers is available. It is through the upload link from the main page. The only details necessary are the server name with which it was registered, the code that is provided at the end of the server-start process, and then the server password (none if there is no password).


A server hosting throwback is online using the latest hosting tool: Carbuncle v2.

The website includes a page where all the servers are advertised. Space is very limited, so hosting up to 255 per server is free for the month of January. Custom maps can be uploaded to the server instance using the Carbuncle client. The client also supports world seeds. If the server does not activate it likely means there is no longer space for new servers.

Carbuncle client is listed as a download in server details.

January Tokens

Carbuncle has been updated to restrict hosting to only clients who have either been given, or bought, an access token. In efforts to continue work on the client software, three free tokens will be granted to those who desire server hosting. Simply send me a forums PM and then I will give you one if you are among the first three.

Carbuncle How-to document -- is a document that explains the client program basics.
If you prefer a website, here is the link.

Future plans

Revising the cost/payment system, and soon the website shop will be available in a monthly subscription-styled service.


Sixteen player slot servers are available using a $5 key obtained from the Gumroad page. The cost is currently approximately $0.30 per player at this time.

Free evaluations can be registered and will last one day.

There is a free offer coming on the first of February to celebrate the US holiday: Presidents' Day.

The process goes something like:
  • Purchase a server key, or simply move on to the next step for the free evaluation.
  • Fill out the form here.
  • Upon completion the process will begin and you will be sent an E-mail with IP, port, and the TShock super admin setup code.
  • (Paid servers last for 30 days.)
  • For the current process -- due to be updated soon -- do not purchase another key at this time when the subscription comes to an end.
  • Map requests are free of charge after the server terminates since the world data will be kept for approximately an extra month.
  • REST API access can be requested, and tserver web has a portal for REST API usage.
For any of the topics listed above, or general service support, support can be reached at: prefect | circleprefect | com (@ and . respectively).

This web page launched today that is a config.json and sscconfig.json form for your server instance.

All that is required is the server identification: the server name plus the TShock setup code which were both E-mailed to you were you to have finished the server request form.


It can be found here to view: Server Manager.

100% Off Discount Codes
Until President's Day this February (Monday the 15th), 3 100% off -- a discount of $5 off -- access keys can be obtained following this link: Holiday Offer.

For those who do not like using their credit card on various websites, you are in luck because it does not require that information for this free offer. The only necessary step is to click the "Subscribe" button on the web page. From there, head to the server register form and supply the access code along with your desired settings.

If you receive a confirmation E-mail within 10 minutes then the process succeeded and the server is running. In this case the E-mail will have all the information for connecting and setting up an in-game super admin account.

Further configuration options can be found at the server manager page.​

An Alternative
If this is not your cup of tea, another holiday deal is a free server that does not require going through the reseller's website -- which lasts one week -- and just requires filling out the form and checking the "Free Evaluation" box.
