I Built 8 Production SaaS Apps with $0 Infrastructure — Here's My Playbook

A self-taught developer from Turkey built and deployed 8 production SaaS applications over the past year using entirely free-tier infrastructure with zero hosting costs. The projects range from an incident management platform (OpsFlow) to an AI competitor analysis tool (RivalRadar) and an MCP server npm package, leveraging tools like Vercel, Supabase, Prisma, and N8N. The author demonstrates that the free tiers available in 2025-2026 are generous enough to run legitimate SaaS products without any infrastructure spending.
