We rolled this out quickly because of the React/NextJS CVE. I think this is actually a really good suggestion and we can look into it! Thank you for the thoughtful blogpost, and I'm sorry we let you down. We will work hard to re-earn your trust.


Bingo. Nix doesn't give you a generalizable-across-languages-and-ecosystems way of specifying specific versions without blowing up your package size, unless you hand Nix to your users (which we didn't want to do)

Maybe we were holding it wrong, but, we ultimately made the call to move away for that reason (and more)


Hey y'all! 3 years ago we built Nixpacks. However, we ran into some pretty large pains using Nix for dependency resolution

So today we're rolling out Railpack, the successor. It results in:

- Up to 75% smaller images - Up to 5x faster builds - Higher cache hit ratio

The goal is to provide a seamless alternative for the Dockerfile frontend. Railpack will automatically find your dependencies, you can add any additional ones, and it'll auto construct the build pipelines for you


We're actually profitable on this round of funding. We've venture backed, but we also wanna make sure people know we're here for the long haul.


Author here. We've talked previously about our datacenter buildout (https://blog.railway.com/p/data-center-build-part-one)

This is the "next step". We're using our baremetal presence to now undercut the "big guys", which means 50% cheaper storage and networking for our users

This is the first week of our launch week so, expect more stuff all this week


We use ~~arch~~ nix BTW

I think, least for us, this is tablestakes stuff. You should be able to get the repo going day 1 and get a commit in

But there's just a fuckload of context beyond the code. You can get it from the RFCs we write internally, but there's still a lot to absorb


Happy to answer any questions. This all seems very obvious in retrospect, but I wanted to share for any other early stage companies in the hopes people can avoid some scaling pains!


That $0.10 per GB is direct pass along for the cloud ingress fees

We can lower that once we’re fully on metal


FWIW this is the advantage of being able to run in the cloud and on perm

If we have to we can “burst” into the cloud


We're blessed with some kickass investors. They gave us just the right level of scrutiny. We were super clear about why we wanted to do this, we did it, and then they invested more money shortly after the first workloads starting running on metal

If you're looking for great partners, who actually have the gal to back innovation, you'd be hard pressed to do better than Redpoint (Shoutout Erica and Jordan!)
