cealshell.dev — a new kind of package manager
creator store — github — website — discordA simple yet powerful package manager.
Why not just use another trusted/known package manager?
This isn’t just another copy of Wally or Pesde, what makes it different is that it’s oriented around Roblox Studio itself, not an external CLI. It’s also registry-less, meaning you can download any github/codeberg repository aslong it has a cealshell.toml file or a release with an .rbxm file in it. I’m also actively open to add more support for providers, just hit me up on discord and I’ll add it.
How do I install it?
Simply grab the plugin from above (creator store/github) and install it. That’s it. No setup needed.
How do I use it?
The syntax is pretty straightforward, cealshell uses the roblox command bar and LogService to catch input. You can get all commands into the output using --c help, there’s also a manual command that gives you extensive information about a specific command.
If you do still need help, visit the documentation. It has information on the basics of usage and more, like how to self-host the proxy.
How does it work?
Cealshell uses a proxy backend (which is also open-source) that fetches the .rbxm files from the provider and uses the rbx-reader library (from NPM) to read these and format them into JSON, making them readable for the Roblox Studio Client. The rest is straightforward.
Limitations
There are some limitations that we cannot bypass, even with user permission.
If too many libraries are installed at the same time, Roblox ratelimits the plugin for an extensive period.
There’s nothing we can do about it, cealshell is based of HTTP Requests.
That pretty much sums everything up. If you have any suggestions or found any bugs, please don’t hesitate and tell me! There is also a roadmap on trello that you can follow.
Not to forget, AI was used in the project. I won’t deny it. The code has been reviewed by myself afterwards, and the model used was Opus 4.8.
You may use cealshell however you like, tho if you use it’s source code please follow it’s respective license. All content of cealshell’s project is licensed under MIT.
