I built 84 free CSS tools in one place — no login, no ads, just tools

Description and use

ToolFlow offers 84 free CSS utilities that run without login, ads, or tracking. All tools are single‑file HTML pages, ensuring fast load times and simple deployment.

Problem

CSS tool sites often load slowly, hide features behind paywalls, or require sign‑ups to copy simple values.

Outcome

ToolFlow delivers fast, free CSS utilities without login or ads, improving developer productivity.

Workflow

• Identify pain points in existing CSS tool sites
• Design a lightweight, single‑file HTML tool architecture
• Implement 84 utilities across categories (Color, Accessibility, CSS generators, Layout, Typography, Utility)
• Host on a VPS with a single rsync deployment
• Publish and promote the free platform

Evidence

Every tool is a single HTML file — no frameworks, no build step, no CDN JavaScript libraries.

Source

The whole site is ~2.3MB total (84 HTML files). It loads fast because there's nothing to load except the HTML + one Google Fonts request.
