Cloudflare Serverless Telegram bot

Cloudflare provides free serverless function hosting, calls workers, and public accessible URL that can trigger the function very quickly (according to their doc, the startup time is just 200ms). Only limitation are the runtime, rate limit and request size

But this still makes it one of the good options to host a small Telegram bot for FREE!
