About us
CaelLab is a youth programming team focused on innovation. We use technology to change the future.
We believe technology can change the world. Our members keep exploring the edges of what's possible, driven by a love of building things. Explore what lies ahead — carry new beginnings.
Since July 2025 we have shipped a series of projects, grown the team, and kept raising our technical bar. We would love to build the next stretch with you.
Milestones
Our milestones
CaelLab is founded
Wang Yaoze registers xuzhoulab.cn, and the team starts making things on the CCW platform. The exploration begins.
First open call for members
The lab opens its doors and invites fellow builders to join.
Leaving Guoyuan Coding Studio
The partnership with Guoyuan Coding Studio ends, and CaelLab sets out on its own.
New services
CaelLab adds a resource centre and a linked cloud drive.
A new wiki?
CaelLab creates and runs Qingzhizhou Wiki.
Games!
CaelLabGameTS arrives.
Writing our own launcher
GoodPlanCraftLauncher ships its first release — a lightweight, efficient Minecraft launcher.
Yunyun waves a hand: XM UER is born
A 19-year-old domain, xmuer.online, is picked up second-hand. CaelLab's sub-brand XM UER is founded, and the forum moves with it.
Doing it ourselves
We build our own coding community. It is called XMUER Coding Community.
A small tool for checking websites
SiteLop goes live, ready to look up information about any site.
Pack up your Scratch projects
XMUER Coding Packager launches, turning Scratch projects into HTML, ZIP or an executable.
Our own coding engine
XMUER Coding Engine launches — an online block editor built on Scratch.
Searching the web
Our own search site, CaelLab Search, goes live.
AI takes the wheel
XMUER Coding Engine reaches 4.0.0 and brings in AI agents that can edit your blocks for you.
A world of blocks?
A new project arrives: CaelCraft.
Works can be forked now
XMUER Coding Community adds forks: one click copies someone else's work into your own account, ready to edit, with credit to the original author kept. Works you no longer maintain can be archived.
An account system of our own
Nomen 1.0.0 is out: a self-hosted account center. Run one copy on a server and several sites share a single login over OAuth 2.0, with two-factor codes, passkeys and 25 interface languages. The project moved to nomenid.org on November 10, and CaelLabID, the lab's own unified login, now runs on Nomen as well.
The community gets rebuilt
XMUER Coding Community has a new front end: a Vue 3 single-page app, so opening a work, a topic or a profile swaps the content in place instead of reloading the page. Addresses and data are unchanged.
