Hey Product Hunt! 👋 I built RapidCave because I was tired of two things: 1. Visiting 10 different websites just to do simple tasks like merging a PDF or compressing an image. 2. Every tool either had a file size limit, required a signup, or slapped a watermark on my output. So I built one platform with 62+ tools that does it all — and everything runs directly in your browser. Your files never leave your device. No server uploads, no accounts, no paywalls. The tech stack is React + TypeScript, and all processing is done client-side using libraries like PDF-lib, FFmpeg.wasm, and Sharp. I'm a solo developer and this is my first major product launch. Would love your feedback — what tools are missing? What would make this more useful for you? Try it at 👉 rapidcave.com — completely free, forever.
