What Vibe Coding Tools is
Vibe Coding Tools is a growing collection of small, focused utilities for developers building with AI: an AI Cost Calculator, an LLM Model Compare, a Prompt Generator, a CLAUDE.md Generator, a Project Brief Generator, an AI PR Review checklist, and an AI Security Checklist. Every tool solves one concrete problem and does it well — and runs entirely in your browser.
Who maintains it
Vibe Coding Tools is designed, built, and maintained by David Dai, an independent developer. There is no company behind it and no venture capital — just one person who ships useful tools and keeps them working. You can reach David directly at hello@david-cells.com.
Why it exists: a privacy-first philosophy
Most online developer tools work by uploading your data to a server. Paste a JWT, a private config, or a screenshot, and it leaves your machine. That is a real risk: tokens leak, files contain secrets, and you rarely know where the data ends up.
Vibe Coding Tools takes the opposite approach. Every tool runs entirely in your browser. Your inputs are processed locally with JavaScript and never uploaded. There are no accounts to create, no servers to send to, and nothing to leak. If you are offline, the tools still work.
How it is funded
Vibe Coding Tools is free to use forever. To cover hosting and development time, the site may show non-intrusive advertisements from networks such as Google AdSense. The tools themselves remain completely free and ad-free in their function.
The bigger idea
The web is full of tools that ask for too much. Vibe Coding Tools is an experiment in the opposite: powerful utilities that respect your data by simply never asking for it. If that resonates, the Blog explains how each tool works and why client-side processing is safer.
