To build a image and push, spwan a pod? Why not just use FaaS service skip the build step?

You don't need to push every time you spawn, only when the code is changed. Typically, you would use a CI/CD action to push the image (this repo has a simple example: https://github.com/drifting-in-space/jamsocket-jupyter-noteb...)

A typical FaaS is stateless between invocations. We have an explicit "spawn" step because each spawn produces a new server process with its own state and own DNS hostname.

What is the latency to start a session?

You can see an example by clicking "new game" on here: https://word.red/ We are working on getting it subsecond for most images, but we're not there yet.

Interesting. Is there a latency difference between first instance of an image and nth?

On the free tier there can be (because images are loaded lazily), but on the paid tier we load the images eagerly so that there is not.

Hey HN! I'm a co-founder of Jamsocket, happy to answer any questions. We've previously been on HN for Plane, which is the open-source engine behind Jamsocket. https://news.ycombinator.com/item?id=33178797 Sorry for the website performance issues, I've disabled the animation which should help.

Yep, your homepage breaks on my imac/firefox due to webgl.

This looks really interesting, and something that could solve a semi-immediate pain point but I can’t find any data on the production plan other than the price. Is that information available anywhere?

Sorry about that, thanks for reporting. Can you elaborate on how it breaks -- does it freeze up or not display at all?
