Building a Private, Browser-Based Toolbox with AI as a Co-Pilot
The developer shares their project CryptoWave, a collection of essential developer and utility tools that run entirely in the browser without sending user data to servers. They discuss how they leveraged AI, like Gemini, to implement complex crypto logic, wrangle WebAssembly, and refine the UI/UX.
Why it matters
This project showcases how AI can enhance a solo developer's workflow to build privacy-focused, feature-rich web applications.
Key Points
- 1CryptoWave is a browser-based toolbox for developers that keeps user data private
- 2The developer used AI as a co-pilot to implement complex features like crypto and WebAssembly
- 3Key features include 100% client-side processing, media tools, developer utilities, and zero tracking
- 4The tech stack includes Vanilla JS, HTML/CSS, FFmpeg.wasm, and CryptoJS
Details
The developer built CryptoWave to provide essential tools like file conversion, image compression, and encryption without requiring users to upload their data to external servers. As an independent developer, they leveraged AI assistants like Gemini to help implement complex functionality, such as ensuring correct handling of AES and RSA operations using CryptoJS, setting up FFmpeg.wasm for local audio and video processing, and iterating on a clean, dark-mode user interface. The project demonstrates how AI can empower a single developer to build tools that previously required a team. CryptoWave runs entirely in the browser, with no data leaving the user's computer, and includes features like media conversion, developer utilities, and zero tracking.
