50 Micro SaaS Ideas for Solo Developers in 2025
The best software ideas often come from subtraction. Instead of building massive, all-in-one platforms, solo developers are succeeding by "unbundling"—taking one or two key features from an enterprise suite and making them a standalone product. This lets you build lean, solve a specific problem, and launch fast.
Micro SaaS focuses on precision, not scale. Forget bloated features; these are small products that solve a specific problem for a clear audience. For solo founders, this model is a huge advantage: quick development (often 4-8 weeks), low maintenance, and recurring revenue without a big team or venture capital.
Here are 50 micro SaaS ideas with real demand, perfect for solo developers in 2025.
