24 alternatives to VS Code Extension to skip the noisy web tools (JSON Prettify, and more)
Hi HN, Simple online tools on the web have become unnecessary greedy. For example, * https://jsonformatter.org/ displays 7 ads on page load * https://convertcase.net/ had 4 ads plus a Google Vignette. And many more sites do the same thing. It's just noisy, which is why I created this VS Code Extension where you don't need to even leave your editor for your small web operations. I also built a Desktop app and an online version, which can be reached or downloaded at smallonlinetools.net. Both of which will be ad-free forever. So far smallonlinetools.net has over…
This VS Code extension provides ad-free access to small web tools like JSON formatting and text conversion directly within the editor, eliminating the need to visit ad-laden websites. The maker also offers a desktop… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. VS Code Extension to skip the noisy web tools (JSON Prettify, and more) launched in 2024; newer entries below may have overtaken it.

utils.foo a fully client side, ads-free developer utils app. Today, it has a timestamp converter, base64/url encoder/decoder, json & diff utils, quick pivoting data. A lot of these exist, but often buried with ads or unclear data usage. I wanted to build something for myself that is ads-free and easy to use. My goal is get to top 20 commonly used tools, make them feature-rich and then reduce the page size. Will appreciate feature/tools requests and feedback at https://github.com/midplane/forum.utils.foo/issues.

An MIT-licensed human-friendly extension of JSON with quality-of-life improvements (comments, trailing commas, unquoted keys), extra types (tuples, bytes, raw strings), and semantic identifiers (think type annotations). Built in Rust, with bindings for Python and WebAssembly, as well as syntax highlighting in VSCode. I made it for those like me who hand-edit JSONs and want a breath of fresh air. It's at a good enough point that I felt like sharing it, but there's still plenty I wanna work on! Namely, I want to add (real) Node support, make a proper LSP with auto-formatting, and get it out…

Let me introduce the Tooltitude VS Code extension. Our extension augments the official GoLang extension with a set of power tools which make you a more productive developer. What do we provide: - Inspections - checks which look at your code and warn you about potential problems in your code. Here’re some highlights - Highlighting of deprecated symbol usages in the editor (gopls doesn’t highlight them at the moment of writing) - Variable shadowing detection - Use of interface{} instead of any - Redundant parenthesis - Code actions - code changes activated by Ctrl+. (Win, Linux), or Cmd+. (on…

JSONBason▲15I've been at it again, just sharing my simple JSON data inspection tool, love webdev and single page apps, this one took 4 days and was a lot of fun. The code is not obfuscated so you can inspect it and see how it works (very simple, server side is even more simple) Pretty much just do a POST of your JSON data from within your code and it will convert it into a basic table for instant search and sort. Made with love for the fun of it, no ads, no paid anything, it's totally free. Please only send in sanitized/test data only, this is meant to help make webdev a bit easier and more fun.…

Tooly▲5I kept opening online JSON formatters and getting buried in ads and popups. So I made a clean version with a few tools I actually use daily – JSON formatter with syntax highlighting, Base64 encoder/decoder, JWT decoder, text diff, and timestamp converter. Everything runs client-side. No tracking, no server calls, no signup walls. Built with React 19 and TypeScript. It's open source: https://github.com/chken007/tooly My 5-year-old helped name it. She insisted on "Tooly" and I couldn't argue with that logic. Open to feedback – especially if you spot bugs or have…
