Building Low-Cost Edge Infrastructure for AI Tools on Cloudflare Workers

As more indie builders launch lightweight AI applications, edge serverless platforms become a tempting choice to minimize bills.
I’ve spent time putting together a reusable stack running fully on Cloudflare Workers, supporting user authentication, subscription billing and event-driven workflows.
Many developers underestimate edge runtime limitations. Common pain points include OAuth compatibility, webhook validation, and environment secret management via Wrangler.
The biggest advantage for small creators: no idle server fees.
The downside: constant debugging for runtime-specific constraints.
Would love to hear how others architect their AI side projects on serverless platforms.
