Micro SaaS is the most realistic path to $5K–$30K MRR as a solo founder in 2026. A micro SaaS solves one painful problem for one specific audience, charges a fair monthly price, and never tries to be a platform. Done right, it's the kind of business one person can run for years without raising a dollar.
This list of 37 micro SaaS ideas comes from patterns we've seen across review sites, niche subreddits, and indie hacker forums. None of them require a team. All of them have at least one paying customer somewhere — meaning the demand is real, even if the current solutions are weak.
What makes a great micro SaaS idea
- Solves one painful, recurring problem — not a platform vision
- Targets a buyer who already pays for software in that category
- Can be built in 30–60 days by one person
- Has a clear, cheap channel to reach the first 100 customers
- Charges $19–$99/mo — not free, not enterprise
