What to Build

whattobuild.today is a demand-intelligence platform for discovering SaaS, startup, and software opportunities using observable market signals.

The platform monitors newly launched websites and emerging software products, then organizes signals such as organic search demand, website traffic momentum, checkout activity, month-over-month growth, and multi-month demand patterns. Its goal is to help builders identify markets where interest and commercial activity may already be developing instead of choosing product ideas based entirely on guesswork.

Users can browse the opportunity radar to discover growing websites, explore emerging SaaS categories, study growth trends, and investigate products showing early traction. Signals from sources such as search trends and public checkout touchpoints help provide additional context for evaluating an opportunity.

whattobuild.today also uses a Build, Watch, or Skip framework to help users prioritize ideas based on factors such as demand, growth momentum, history, and competition.

The platform is primarily useful for indie hackers, solo founders, developers, AI builders, and small product teams researching their next project. Common use cases include discovering SaaS ideas, validating a niche before building an MVP, monitoring emerging software categories, and finding competitors or products worth researching further.

It is intended to make the early stages of product discovery more evidence-driven while leaving final validation, customer research, pricing, technical feasibility, and go-to-market decisions to the builder.
