Frequently Asked Questions

How are these SaaS ideas validated?
Each idea is evaluated against real market signals: search volume trends, community discussion frequency on Reddit and Hacker News, existing competitor count, and estimated willingness-to-pay based on adjacent products. We score competition level, market timing, and revenue potential before publishing.
Are these ideas free to use?
Yes, every idea is free to browse with no paywall. You can use any idea as a starting point for your own product. Ideas are not patented or proprietary. Multiple people can (and often do) build in the same space with different approaches.
How often are new ideas added?
We add new ideas regularly based on emerging market trends, new technology capabilities (especially in AI/ML), and gaps identified through community feedback and keyword research.
What does the MRR potential estimate mean?
MRR (Monthly Recurring Revenue) potential is estimated based on: the target audience size, typical willingness-to-pay for similar tools, the competitive landscape, and realistic market capture rates for a bootstrapped product. These are ranges, not guarantees.
Can I submit an idea?
Not yet, but we plan to add community submissions in the future. For now, all ideas are researched and authored by the IdeaPlan team to maintain quality and consistency.
What makes a good micro-SaaS idea?
The best micro-SaaS ideas solve a specific, painful problem for a well-defined audience. Look for low competition, clear monetization (people already pay for similar tools), and a scope you can build as an MVP in weeks, not months. The ideas here are filtered for these qualities.
How do I validate an idea before building?
Start with our TAM Calculator to size the market, then use the RICE Calculator to prioritize features. Talk to 10-15 potential users, check search volume trends, and look for people complaining about the problem on Reddit, Twitter, and niche forums. Build a landing page before writing code.
