We have created this platform in 4 days during our Easter bank holidays. The main stack is React, NextJS, Hasura, Vercel now, Cloudflare Workers and Digital Ocean. We are positive that we can scale to 100.000 concurrent users with this setup on infrastructure for $40/month.
We are a non-profit and our main goal is to make pricing of masks and other protective gear more transparent.
Looking forward to reading your feedback :)
