Think of this as a developer's ultimate Swiss Army knife. It's a personal sandbox containing 67+ online compilers and dozens of utility tools like PDF compressors, video editors, and image converters. I built this because I got tired of using online tools that are slow, bloated with spammy ads, or force you to sign up for a subscription just to crop a video or compress a PDF. Everything here is clean, fast, and built with developer privacy in mind.

Yes, completely! There are no subscription fees, no premium tiers, no account sign-ups, and no paywalls. For tools that run on our servers (Online Mode), we have basic rate limits (e.g., up to 5 files per minute) just to prevent spam bots from overloading the server. But for you, there are no monthly caps or credits to worry about.

Your privacy is the most important feature here. If you use Offline Mode, your files are processed entirely on your own device using WebAssembly (WASM). Your files never touch our servers and never leave your computer or phone. If you choose Online Mode (which is faster for massive files), your files are uploaded securely, processed in memory, and then deleted permanently and immediatelythe moment the task is complete. We do not store, inspect, or sell your files.

For client-side languages like HTML, CSS, JavaScript, and Markdown, the code runs instantly inside your browser. For backend languages like Java, C++, Rust, Swift, and Go, your code is sent to an isolated, secure compiler sandbox (using Judge0 or custom servers). The code runs in a temporary micro-container, and the output is streamed right back to your console. Your code is processed in memory and never saved permanently.

Yes! This website is a Progressive Web App (PWA). You can install it on your Mac, Windows, iOS, or Android device directly from your browser (just click the install icon in the address bar). Once installed, all tools that support Offline Mode will work completely offline, even if you are on a plane or have no network signal.

Offline tools run desktop-grade engines (like FFmpeg for video or PDFium for PDFs) directly in your browser. The first time you load an offline tool, your browser has to download these WebAssembly (WASM) compiler engines. After that first download, your browser caches them locally, and they will load instantly on all future visits.

I'd love to hear your feedback! If you find a bug or want to suggest a new tool or compiler, you can click the "Report Bug" link in the top menu, reach out to me via email at hello@avijit.dev, or connect with me on LinkedIn.
