How does Dig validate an app idea?

Dig scans 70+ live data sources including App Store, Google Play, Reddit, X, YouTube, and Product Hunt. It returns a competitor list, pain points, market gaps, SWOT analysis, and an opportunity score from 0 to 100. The process takes approximately 5 minutes.

Is Unbuilt free to use?

Pulse (the daily launch feed) is completely free with no account required. Dig (market analysis) and Stack (build plan) each cost 1 credit per report. Unbuilt also hosts 2,400+ free app idea analysis pages at unbuilt.me/ideas.

Open source Any.do alternative

You're looking at a market where thousands of developers want task management without corporate lock-in, but most open-source alternatives either lack polish or abandon users after launch. The demand is real—Any.do has 10M+ users—but the friction point is that switching costs from proprietary apps are still too high.

Key insight: The market doesn't need another feature-rich open-source task manager—it needs one where a non-technical founder can click 'self-host' and have a working instance in 60 seconds, with zero configuration.

Market Overview

There are roughly 30-40 legitimate open-source task/productivity tools competing in this space (Vikunja, OpenTodoList, Plane, Focalboard, Taiga, etc.), but only 5-7 have meaningful traction and active communities. The core pain points are UI/UX debt, mobile app fragmentation, sync reliability across devices, and lack of collaborative features that don't feel clunky. The actual gap isn't in features—most open-source tools match Any.do feature-for-feature—it's in discoverability, self-hosting ease, and friction-free onboarding for non-technical users. A new entrant should focus ruthlessly on one specific job-to-be-done (personal task capture vs. team workflows) rather than trying to compete on feature parity. The real opportunity is building for teams that want offline-first, zero-telemetry task management without the complexity of Docker and PostgreSQL setup.
