Github seems like they're gearing up to offer a similar service [0]. Cloud9, and notably Glitch [1] offer similar and well executed services. [0] https://github.com/atom/xray#web-compatibility [1] http://glitch.com/

Just for the sake of listing, what "alternatives" are available today ? I can think of 1. Codepen (pure HTML+CSS+JS+frameworks) 2. jsfiddle.net/ (pure HTML+CSS+JS+frameworks) 3. Cloud 9 (full ide?) 4. https://anvil.works/ (pure Python) 5. CaptainDuckDuck ? 6. Repl.It 7. https://glitch.com/ 8. Runkit.io (pure node.js) Other ?

I'm wondering why repls aren't expensive to host. Is there a virtual machine running all the time for each repl? Do they swap out idle repls somehow?

Repls are container-based. We control how much resources each repl can use and so we can control how it much it costs. We do swap out idle repls and wake them up on the first request that comes in (heroku style).

How do you start up these containers so quickly anyways? Do you keep some running hot, or delegate the startup to something like amazon's ECS? I've long wanted to run integration tests en masse in containers, but never figured out how to solve issues around long startup times.

Hey HN, author and Repl.it cofounder here. It's been a long journey to get to what we're calling 1.0 and HN have been there on every step of the way. We started working on what became Repl.it back in school where we were tired of setting up the development environment on every machine we wanted to code on. It was at a time where everything was moving to the cloud and we thought that, naturally, coding would follow su…

I'm teaching a couple of kids coding (they taught themselves a bit before I got involved so it's pretty fun!). We're totally going to use this. Thanks! Is a Typescript option in the pipeline? It's my favorite :)
