I tried Plasma ( with i3 to replave kwin, didn't turned out to be a goo experience btw, back to bare i3) some times ago and directly deactivated this baloofile after seeing it was taking 1.7gb at boot ( maybe it was temporary ). I just use fzf when I don't know where something is.

React is free and open source, they could always fork it and I guess they are protecting their backs by supporting Vue and Svelte ( employed the creator full time to work on Svelte )

Haven't yet used their /api serveless functions but I guess it's standard nodejs functions, so not that much vendor lockin

CDN (edge network as they call it) + host your serverless functions. All that automatically after you push your code to a remote git repos.

I read earlier today on their website that they were offering free plans to open source projects, aybe they also do it for non profit

Correct, we support a number of non-profits as well.

Remix have just been released and you're already jumping to conclusions ? What's missing from NextJS to connect your own backend framework like django rails express or whatever ? Or even using their api routes + something like Prisma and a SQl/NoSQL database ? Basically nothing.

People just like React and the idea of decoupling frontend and backend ( Pretty sure just a few percentage of users use Nextjs with api routes and just use it as Create-React-App with SSG and SSR capabilities ). I haven't used Vercel that much in production but what does it bring compared to Heroku or cheaper and open source self hosted alternatives like Dokku or even caprover with it's really good UI and can deploy any backend as long as it's Dockerizable ?

Because React is now a standard in the frontend I guess, so people are looking for a way to get that Django/Rails fullstack experience but with React instead of templating language and because it's extra work to write a django/node/rails api and a decoupled JS framework frontend.

Meanwhile everyone is also trying to have a decoupled infrastructure and going with microservices. It's an endless loop I guess.

Why not using Caprover ? That's an open source self hosted PaaS that use Docker and let you configure almost everything through their GUI, as well as checking Logs, easily scale horizontally, spinning up Postgres/Redis/Next cloud or whichever docker images in one click and letting you communicate via different parts of your projects through environment variables set through the GUI.

That way instead of learning a new and likely less advanced framework you can use your favorite and likely more mature and well maintained backend framework and just deploy in a minute with caprover, as long as you can dockerize it it should work, you just have to write a single dockerfile ( they also have a way to not write dockerfiles directly and use their abstraction ).

You take advantage from the backed framework you already know with all its advantages and also benefit from Docker's huge community. Their UI is really good to be honest, you can enable and force https in one click and other goodies like that, DigitalOcean also have a preconfigured Ubuntu droplets with caprover preinstalled to make it even smoother.

Angular Vue and Svelte fit your description and none of them are more popular than React, I guess people have made their choice.

It's an open question whether React succeeded because of technical advantages or because of Facebook's initial support and the job market creating its own dynamic (people go where the jobs are).
