Quick Answer: You can run a production micro-SaaS application for $0.00/month by combining Cloudflare Pages (unlimited bandwidth edge hosting), Turso / libSQL (9GB free distributed SQLite database), and Resend (3,000 free transactional emails/month). This stack delivers sub-20ms global edge latency and scales effortlessly up to 50,000 active monthly visitors without a credit card charge.
