Building production SaaS entirely on Cloudflare Workers – Lessons learned

I’ve been developing my SaaS platform built fully on Cloudflare Workers edge infrastructure.

Edge computing offers huge benefits for solo founders: zero idle server costs and global low-latency performance.

However, I ran into many undocumented hurdles during development:

• Auth.js adaption issues for edge runtime

• Tricky differences between wrangler dev and production environment

• Stripe webhook validation & Resend email domain DNS configuration

Most tutorials only cover isolated code snippets. It’s challenging to find guides for a complete production stack including authentication, subscription billing and transactional emails.

If you’re building tools on Workers, I’d love to exchange experience.
