Visualize Habit

A small, single-page habit-visualizer is realistic for one technical user to build and maintain; there are no evident durable moats and open-source habit trackers provide useful prior art.

Not priced

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Visualize Habit alternatives, with the arithmetic →

What a replacement has to do

  • Enter a list of tiny habits, compute time/quantity projections over a period, render a visual grid and summary, allow export/share.

What it still won’t have

  • Design polish and micro-interactions from the original UI
  • Any proprietary analytics, A/B testing, or hosted uptime guarantees
  • Cross-platform packaged apps or platform-specific integrations (if present)

What remains hard

  • Product polish and ongoing maintenance

First-year cost

No published price

Visualize Habit does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt

Not run yet
Build a single-page web app using React, TypeScript, Vite, and Tailwind; store data in localStorage and provide optional JSON export/share. In scope: habit editor (name, unit, frequency, duration), a projection engine that computes 1-year and 10-year totals and converts units (e.g., hours, pages, steps), a responsive habits grid visualization and summary cards, export-to-PNG and export-to-PDF, input validation, and unit tests (Jest/React Testing Library). Out of scope: user accounts, server-side sync, paid tiers, analytics tracking, and mobile-packaged binaries. Include error handling for malformed inputs, boundary cases (very large numbers), and automated tests covering core computations and UI flows.

How the score was reached

  • Build verdict base78
  • An open-source build was found+5
  • 3 cited sources+3
  • 3/3 assessment runs agreed+4
  • Evidence score90

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
