Design and diagrams decision
LogoFast
A one-person developer can reproduce the core LogoFast functionality (icon picker, styling, preview, export) in about a week using open-source icon sets; the vendor's hosted polish and curated presets are what you'd give up.

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 LogoFast alternatives, with the arithmetic →
What a replacement has to do
- Pick an icon, tweak size/rotation/color/border, preview on background, download PNG/SVG, save/load simple presets.
What it still won’t have
- Integrated curated presets and bundled icon library ('Presets', 'Icons by Lucide' shown on site)
- Hosted hosting, uptime, and ready-made polish of the vendor web UI
- Any proprietary datasets or undisclosed features not shown on the pages
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
LogoFast does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-page React app (Vite + React) deployed to Vercel or Netlify that lets a user select an SVG icon from a local bundled icon set (use simple-icons), adjust size, rotation, fill color, fill opacity, border width/color, and background color, preview changes live, save/load simple presets to localStorage, and export a downloadable SVG and high-resolution PNG. Persist no server-side database (static JSON presets). Out of scope: AI logo generation, user accounts, payments, analytics. Include error handling for export failures, accessibility attributes, and unit/integration tests for the export and preset flows. Provide a Dockerfile for local builds and CI config to publish to Vercel/Netlify.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 5 cited sources+3
- Evidence score86
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.
