Hi, my name is Andrew and I'm the founder of mainbrella co. Just a few days ago Cloudflare launched their container sandbox service. That inspired me to see what I could build in terms of a better e2b.dev or daytona.io type system. It is all open source GPL 3.0 and we offer the same services as the other players. We have no free plan (our base builder plan is $5 a month) but you are welcome to run the code in your own Cloudflare account.

The numbers are pretty good in terms of startup speed. First test we ran was: Create a fresh sandbox, get a usable shell 381 ms, 30 out of 30 tries worked the same speed. Then 100 simultaneous sandbox starts 680 ms avg 100 / 100 successful 100 distinct machines running at once!
