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 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

You're looking at a market where Excalidraw owns mindshare but doesn't own loyalty—most users stick around because it's free and open-source, not because competitors don't exist. There are roughly 15-25 viable alternatives right now, and that number is growing as design tooling gets cheaper to build.

Key insight: Excalidraw's real moat isn't the product, it's the open-source community trust and zero friction onboarding—beat it by picking one vertical (engineering teams, UX researchers, educators) and owning that workflow so completely that switching costs exceed the switching incentive.

Market Overview

The whiteboarding and diagramming space is surprisingly crowded, with tools ranging from Miro and Figma Jam at the premium end to Tldraw and Wireflow in the open-source tier. The core pain points aren't about basic sketching anymore—Excalidraw solved that—but rather integration friction, real-time collaboration at scale, and export workflows that don't suck. Most alternatives fail by either trying to do too much (feature bloat that slows down the actual drawing experience) or staying too narrow (repo-only communities without a real product motion). The actual gap sits in the middle: a tool designed specifically for technical teams who need Excalidraw's speed and aesthetic but also need seamless handoff into design systems, Figma, and code generation. A shipper entering this space should obsess over one specific workflow—say, turning sketches into component libraries or architectural diagrams that sync to documentation tools—rather than competing on being a Swiss Army knife.
