Built a Hyrox training plan database last year after my friends & I spent weeks researching plans. Started with a no-code tool but refused to pay $130/year, so I rebuilt it myself with Claude Code. 20-30 hours total and it was my first real web project (python background).

Runs on Vercel free tier, costs nothing beyond the domain: https://www.hyroxtrainingplans.com/

Not perfect, but it's live and people use it.
