EgoCX Lab is the experimental playground of EgoCX. Here you will find a curated collection of free, privacy-first web tools, interactive demos, and creative utilities — all built to solve real problems without compromising your data.

About the EgoCX Lab

Every tool in this collection was born from a real need. Some were built to scratch our own itch — a repetitive task that had no good free solution. Others emerged from client projects and were later generalized for public use. A few started as weekend experiments that turned out to be surprisingly useful.

Our Philosophy

We believe that great tools should be accessible, private, and free of unnecessary complexity. That's why every application in this lab runs directly in your browser, stores data locally, and never sends your information to external servers unless you explicitly choose to (for example, by providing your own API keys).

What You'll Find Here

  • AI-powered content generators that leverage the Gemini API (with your own keys).
  • Branding and typography tools for font testing, color palette generation, and typo research.
  • Domain and SEO utilities for investors, marketers, and web administrators.
  • Developer tools for JSON processing, CSV viewing, text manipulation, and more.
  • Productivity apps like private notes and file managers.

Contribute

The lab is open-source by nature. You can inspect every line of code in your browser. If you have suggestions, bug reports, or ideas for new tools, we'd love to hear from you. Reach out via the contact page or contribute on GitHub.

Tools, Demos and Creative Utilities

EgoCX Lab: Your Gateway to Free, Private Web Tools

The internet is full of web tools. But too many of them come with strings attached: mandatory accounts, expensive subscriptions, hidden data collection, or intrusive advertising. EgoCX Lab was created to be different — a curated collection of professional-grade utilities that respect your time, your privacy, and your intelligence.

Why This Lab Exists

Every tool in EgoCX Lab started as a solution to a real problem. The font tester was built because designers were tired of uploading client fonts to sketchy third-party websites just to see how they rendered. The domain manager was created because tracking expirations across multiple registrars was a spreadsheet nightmare. The content factory was born from the frustration of hitting API rate limits when generating SEO content at scale.

These are not hypothetical use cases. They are the actual reasons why EgoCX sat down and wrote code. And because the studio believes in sharing, every tool ended up in this public lab — free for anyone to use, modify, and learn from.

What Makes These Tools Special

Privacy by design. No tracking scripts, no analytics, no server-side logging. Every tool runs entirely in your browser. When you upload a font, it stays on your machine. When you generate content with an API key, that key never touches our servers.

Offline capability. Most tools work without an internet connection after the initial page load. This makes them ideal for use on planes, in secure environments, or anywhere connectivity is unreliable.

Single-file architecture. The majority of these applications are self-contained HTML files. You can download them, carry them on a USB drive, and run them anywhere.

Real-world testing. These tools are used daily by their creators before they ever reach the public. Bugs get fixed quickly because we encounter them ourselves.
