Heyo! Angelo, Support Engineer from Railway here. Just replying here to let ya know that if you attach a card/load credits into your account. You get an unrestricted $5 a month free for your projects.
Similar to what other HN commenters mentioned on this and other threads. Offering unrestricted compute online tends to be hard to manage from an abuse perspective.
Aside from that: just here to answer any questions about the product/roadmap. We want your workloads to be successful, on Railway or anywhere else. :)
