If Figma runs perfectly well in a web browser, Reddit can do the same. It was built for and evolved almost entirely within the browser, like many other Internet forums. Pure data grab.
Figma shows what it is possible to do in a browser, but the cost of doing so is basically prohibitive. The level of persistence and technical nous needed to stand it up are on par with getting a first-person shooter running at an interactive frame rate on a 286 -- they basically reimplemented a browser within the browser.
According to Reddit's "Staff Platform Engineer (Web Platform Team)":

Old Reddit has the advantage of being pretty much static non-interactive content. No video, tiny thumbnails, and barely any JS or styling. Some people like this and some don't, but the end result is a very lean website that performs well out of the box.
Which is of course a bunch of bullshit when you consider that Reddit's backend returns most data in under 400ms, and it takes Reddit frontend 3+ seconds to render it
Figma is sort of an Apollo Project among webshit, isn't it? IIRC they did rather extreme amount of R&D to make the webapp performant in spite of the web as a platform. Great that they did, and I hope their insights will keep trickling down to everyone else - but I don't think they're currently an example anyone can actually follow.
It’s great, but it’s not Apollo-level anything. Most games are far more interactively and visually complex. Apples to oranges with UX and interaction problems to solve, but certainly not depth and complexity. I’ve certainly experienced bugs in Reddit’s interface before — there seems to be this idea that they have to be so risk averse that they can’t do anything significant— I’ll bet you a pizza that their official app which implements all the features that people really want to use is made with JS/HTML on the back end anyway.
