Questions & Answers

As answered by people managing LeechBlock and Devtoolry.

How would you describe the primary audience of your product?

Devtoolry's answer:

Developers and computer science students who need to quickly run a snippet, format or validate data, compare text or convert files without installing anything, and anyone who prefers that their code and documents stay on their own device.

Why should a person choose your product over its competitors?

Devtoolry's answer:

Most online compilers and converters upload your code or files to their servers and often ask you to sign up. Devtoolry processes everything locally in the browser, needs no account, and keeps compilers, JSON and text tools, PDF and image tools, generators and time tools in one consistent interface with dark mode and keyboard-friendly editors.

What's the story behind your product?

Devtoolry's answer:

I'm a solo developer from India. I kept switching between a dozen different sites to format JSON, run a quick C program or compress a PDF, and many of them uploaded my files or were full of pop-ups. I built Devtoolry as one clean place for these everyday tasks, with everything running in the browser.

What makes your product unique?

Devtoolry's answer:

Everything runs in your browser. The online compilers don't send code to a server: C and C++ are compiled with Clang to WebAssembly, Go uses the real Go toolchain targeting wasip1, and Python, PHP, Ruby and R run in Web Workers. The same applies to the PDF and image tools, so files are never uploaded. It is also one site with 120+ tools instead of a separate site for each task.

Which are the primary technologies used for building your product?

Devtoolry's answer:

Next.js, React, TypeScript and Tailwind CSS, with CodeMirror for the editors. In-browser runtimes: Clang compiled to WebAssembly, the Go toolchain on WASI, Pyodide (Python), php-wasm, ruby.wasm, webR and sql.js, all running in Web Workers. PDF tools use pdf.js, pdf-lib and qpdf compiled to WebAssembly; the background remover runs ONNX models with onnxruntime-web.
