Unbuilt is a market intelligence platform for vibe coders, indie hackers, and no-code founders. It has three tools: Pulse (free daily launch feed), Dig (market analysis scanning 70+ live sources), and Stack (build plan from 700+ tools).

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.

Vibecoding is building software using AI-powered tools like Cursor, Lovable, Bolt, Replit, and v0. It allows non-traditional developers to create apps quickly. Unbuilt helps vibe coders validate their ideas before building.

How many app ideas does Unbuilt analyze?

Unbuilt hosts over 2,400 pre-analyzed app idea pages covering 25+ categories including SaaS, AI tools, developer tools, productivity, finance, health, and education. Each page includes an opportunity score, competitor count, and market overview.

Is Excalidraw alternative for startups worth building?

With an opportunity score of 42/100, this is a moderately competitive space with some opportunities. For a full analysis, use Dig at unbuilt.me to scan 70+ live sources.

Excalidraw alternative for startups

You're looking at a crowded but still fragmented market where dozens of tools claim to replace Excalidraw, yet most startups still default to the original because switching costs (learning curves, integration friction, feature parity) are real. The whiteboard diagramming space is growing 20-30% annually, but the alternative narrative hasn't solidified around any single winner.

Key insight: The real moat isn't beating Excalidraw on features—it's embedding yourself into a startup's core workflow (like internal docs, design-to-code, or API visualization) so deeply that switching becomes operationally expensive, not just technically inconvenient.

Market Overview

There are roughly 25-40 direct competitors claiming to replace or improve on Excalidraw, ranging from lightweight sketch tools (Tldraw, Wireframer) to more feature-rich alternatives (Miro, Mural, FigJam). The common failure pattern is trying to be everything—collaboration, real-time sync, design systems, and infinite canvas all at once—which either bloats the product or stretches engineering too thin. The actual gap isn't in features; it's in the startup-specific workflows that existing tools ignore: sub-$100/month pricing for small teams, zero onboarding friction, offline-first or self-hosted options, and API-first architecture for embedding diagrams into custom apps. Most startups either pick Excalidraw (free, open-source) or jump to enterprise tools like Miro (overkill and expensive). A new entrant should obsess over one specific workflow—say, technical architecture diagrams for dev teams, or product spec visuals for founders—and own that deeply rather than chasing feature parity across use cases.
