Launching a project isn't free but doesn't have to be expensive. I'll maintain this post with a breakdown of things I've spent money on.
|Server (Hetzner Cloud)||~£4/month|
I use Hetzner Cloud for various other websites so it was a no brainer to just spin up a new server, reset it to a snapshot I already had that gets me 90% of the way there in terms of setup and build from there.
This is billed monthly based on usage but I expect it will be similar to my other servers and be about £4 per month.
123-reg.co.uk had a sale on for new 1-year domains so it cost £1.99 + some admin type nonsense. Bargain!
Unfortunately, I'm not a designer so I thought I'd invest in just grabbing a theme that I can modify to get a nice looking application while saving some time. Even if I just use bits and pieces from it I think I'll be ahead time-wise.
