    Railway isn't part of Figma's setup in this story. It's just an easy place to try the same building blocks.
  • Better Stack · Monitor uptime and logs with Better Stack, and get alerted fast if a migration or traffic spike goes sideways on your own system.
    Better Stack isn't part of Figma's setup in this story. It's a tool for watching your own systems while you try ideas like these.
