As answered by people managing OpenStartup.dev and ScoreMySaaS.
ScoreMySaaS's answer:
Most micro-SaaS die from the market, not the code: a flawless product for a pain nobody pays to solve. We turned a battle-tested validation methodology into a scoring engine, so founders can spend one honest hour instead of six months finding out the hard way.
ScoreMySaaS's answer:
Solo founders and indie hackers considering a micro-SaaS — especially developers who can build anything but want to check whether the niche is worth months of evenings before writing code.
ScoreMySaaS's answer:
The score is deterministic, not AI-generated: the same idea always gets the same 0-100 score, computed by fixed rules across 8 axes (pain, willingness to pay, niche focus, benefit vs price, feasibility, market, geo focus, launch type). AI is used where it adds value — live market research and go-to-market copy in the paid report — but the verdict itself is reproducible methodology, not vibes.
ScoreMySaaS's answer:
The free tier gives a real 0-100 score with no signup. The $49 report goes further than a verdict: live competitor research with actual pricing, a go-to-market plan with ready-to-run ad copy, a build estimate, a bottom-up market size calculation and Mom Test interview questions. Most alternatives stop at "good idea / bad idea" — ScoreMySaaS hands you the next steps. It also works in 5 languages.
ScoreMySaaS's answer:
Next.js on Cloudflare Workers (edge-rendered, global), with Anthropic's Claude for live market research and report generation. The scoring engine itself is deterministic TypeScript — no LLM in the score.
