we moved to bare metal and can now spinup devboxes in <3s this also includes repo & deps so you can spin up a dev server or run typecheck w no extra setup need more compute... need... to... scale...

if a sandbox only works when you prompt it right, it's probably the wrong tool for dev work general purpose sandboxes are the vps of dev environments. they can run anything, so the workflow is on you, and with agents "on you" means your prompt e.g for dev boxes, speed, integration and flexibility matter more than being able to spin up 1000 minecrafts
You told your agent to use boat wrong. Still spin up worktrees and edit code locally. The point of the boat boxes is to quickly sync up the changes to do anything that requires real cpu/ram Point made though. I might have to ship cloud sandboxes as a paid feature just because people have prompt skill issues 🙃

this is not a hit to boat or any other sandbox companies, obviously there's still value in the race to the bottom but if you need a quick website hosted somewhere, you would probably pick vercel > aws

1500 agents is easy; here's 10k agents all logging in and playing minecraft together on sailboxes in realtime. 10k VMs with 10K vCPUs, 21TB of RAM, 86TB of disk. This capacity is all available for $250/month entirely self-serve with the new Sail Pro plan (along with active-everything billing and no creation fees). Try it out today!

super excited to finally share what I've been working on! as coding agents become more capable, we think that 1. you should not be limited by the resources on your laptop 2. agents/IDE should run on seperate machines from the dev environment our goal is for @tesser_sh to make development infrastructure feel invisible much more to come 🫡
introducing @tesser_sh (YC W27) tesser is the simplest way to offload heavy workloads like dev servers and builds to cloud VMs. every worktree gets its own machines, with automatic port forwarding to your laptop
