A developer built a Chrome extension in a weekend. It auto-formats citations in Google Docs. Nothing fancy. He charges $12.99/month and 340 people pay every month without thinking about it. That's $4,200/month from a tool he spends 3 hours a week maintaining. No investors. No team. No pitch deck. Just a small tool solving a specific problem for people willing to pay.

The Micro-SaaS Side Project Playbook is the developer's guide to building small software products that generate recurring revenue. Inside: 30 validated micro-SaaS ideas with pricing data, a 48-hour validation sprint that proves demand before you code, a weekend build schedule from setup to Stripe integration, pricing frameworks based on value delivered not time spent, the exact playbook for getting your first 100 customers, and the growth levers that take you from $0 to $10K MRR in 12 months.

Week 1: validate. Week 2: build and ship. Week 3: launch and get your first 10 customers. In 90 days you'll have a live product generating $1-2K in monthly recurring revenue. The best micro-SaaS products are boring -- they solve tedious problems nobody else bothers with. That's exactly where the money is.
