Show HN: 2.7KB Zig WASM – live globe showing executions at 300 CF edges

https://mcpaas.live/globe

36 cities so far. Every visit lights up your dot.

It's really annoying that you can stop the globe from rotating. This also feels exactly like a Claude-built website, which is unsurprising.

Looks like they just updated it. Check under the globe.
wolfejam•1h ago
use the pause button below it, zoom in/out, rotate too

"36 cities so far. Every visit lights up your dot."

You paid to patent this, whatever it is. How about more than two sentences to see what you're charging people for. I can't tell from the website's "About" page.

Edit: Even the github link is a 404, I give up.

MCPaaS is trademarked. Nothing it patented.

Thanks for flagging the broken link. More context here: https://mcpaas.live/about

Plus a 1.8 MB Javascript file ;)

...that's too big for a JS shim to talk to browser APIs... it looks more like a complete 3D engine - e.g. three.js or similar?

From that pov the 2.7 KB WASM is a bit misleading (or rather meaningless), it could be a single function call into that massive JS blob where all the work happens.

ivanjermakov•1h ago
Three.js alone is ~400KB uncompressed.
wolfejam•39m ago
Yep — Three.js renders the globe client-side. The 2.7KB scores server-side at the edge. Separate concerns.
eknkc•59m ago
This is a completely baffling website but as far as I can tell, the 2.7 WASM thing is the MCP runtime this is marketing? The globe thing is independent of that, just showing there the MCP calls are running.
wolfejam•42m ago
The 2.7KB Zig WASM binary is the scoring engine that runs on every request at Cloudflare's edge. The globe visualizes where those requests land. Two layers — compute at the edge, visualization in the browser.
wolfejam•59m ago
Fair point — globe.gl (Three.js) handles the 3D rendering client-side.

The 2.7KB WASM is the server-side scoring engine — Zig-compiled, runs on every request at the Cloudflare edge. The globe visualizes where those executions happen.

Two separate layers: WASM at the edge, JS in the browser.

Ah ok, might have made more sense to link to the about page tbh, but that probably would have looked too obviously like an advertisement ;)
wolfejam•22m ago
just trying to show the zig-wasm binary and CF edge :)
topspin•1h ago
It there some law that mandates all 3D globe renderings auto rotate and omit any way to stop it?
wolfejam•1h ago
use the pause button below it
topspin•1h ago
Thanks! I see that just got added.
Dwedit•1h ago
WASM + Zig (even compiling C code) will make some really tiny WASM files with no dependencies. The problem is that you don't have a standard library, then your code gets really big as you add more of that in there.
wolfejam•56m ago
Exactly right. 2.7KB works because it's pure computation — slot counting, no allocator, no stdlib, no WASI. The moment you need I/O it balloons. This use case fits a glove

Looking at the website of the organization [1] of the author, linked at the bottom of the submitted link, I get serious Time Cube [2] vibes.

I'm both fascinated and worried about what the internet will look like in five years.
