Micro-SaaS -- small, focused software products serving a niche market -- is the most accessible path to recurring revenue in 2026. Unlike venture-backed SaaS, micro-SaaS products can be built and run by a single person. As a developer who builds micro-SaaS products and SaaS MVPs, here are 15 ideas with real market potential.
What Makes a Good Micro-SaaS Idea
Before the ideas, here is what to look for:
- Small, defined market: 1,000-10,000 potential customers is ideal
- Recurring pain point: Something people deal with weekly or daily
- Willingness to pay: B2B niches (EUR 20-200/month) convert better than B2C
- Low competition from big players: If Salesforce or HubSpot can add it as a feature, avoid it
- Your unfair advantage: Industry knowledge, technical skill, or existing audience

How to Validate Before Building
- Find 10 potential customers in the target market. Talk to them about the problem. Do not pitch your solution.
- Check willingness to pay: "If this existed, would you pay EUR X/month?" If fewer than 7 out of 10 say yes, pivot.
- Build a landing page with a waitlist. Run EUR 200 in Google Ads. If you get 50+ signups, the demand is real.
- Build the MVP in 4-6 weeks. Not the full product -- the minimum that solves the core problem.
