100% browser-local developer tools & playable AI games

Hi Product Hunt community! 👋
I’m the creator of **PocketKit**. I am incredibly excited to share this project with you all today!
### 🔒 Why I built PocketKit
Like most developers and digital creators, my browser bookmarks were cluttered with quick utilities: merging PDFs, formatting JSON, decoding JWTs, or checking GPT tokenizer counts.
But I’ve always felt a sense of anxiety pasting client data, API keys, or sensitive contracts into random online tools. We never know if those servers are caching our inputs.
That’s why I built PocketKit — a **100% browser-local, privacy-first toolbox**.
### 🛠️ What makes it special?
1. **Zero Data Uploads**: Everything runs locally in your browser sandbox using Web APIs and WASM (e.g., local PDF compiling). No servers see your files. It even works completely offline!
2. **PWA Standalone App**: You can install it on macOS/Windows in one click. It runs in a standalone native window, ready whenever you need it.
3. **AI-Generated HTML5 Games**: I used LLMs (Claude & Fable) to "prompt" 20 retro games (like *Ice & Fire*, *3D Tank Battle*, *Mini MOBA*).
4. **Open-Source Prompts**: I’ve published the **exact English Prompts** I used for every single game on their detail pages. If you're studying prompt engineering for code generation, this is a playground for you!
5. **SEO & Speed Optimized**: Built with Vite+React, optimized with Playwright pre-rendering for instant loads and SEO fallback.
### 💬 Let's chat!
PocketKit is 100% free, has no ads, and requires no registration. I’d love to hear your thoughts:
* Which developer tools do you use most frequently on a daily basis?
* What are your thoughts on prompt engineering limits for full-game generation?
I’ll be here all day responding to your comments and feedback. Thank you so much for the support! ❤️
