What’s the biggest pain point when building full-stack apps on Cloudflare Workers?

I’ve spent weeks building out an edge-first stack entirely on Cloudflare Workers.

Combining user authentication, payment event handling and transactional emails at the edge comes with lots of hidden runtime limitations.

Some obstacles I worked through:

• OAuth provider compatibility under edge runtime

• Securely consuming payment webhooks without traditional servers

• Reliable email delivery for user events

• Consistent deployment workflow with Wrangler

Many existing examples only cover isolated features instead of an integrated system.

I’m curious — what blockers slowed you down when building serverless edge applications?
