🧰 a web-based swiss army knife for developers


git clone ssh://git.ovine.xyz/webtoys


A handy and easy-to-use collection of tools every developer needs at one point or another. It's a web-based clone of DevToys built with Next.js.


Because not everyone is a Windows user :)


WebToys is in the very early stages of development and most tools are not yet implemented. I am aiming for 1:1 feature parity with DevToys eventually, wherever that's feasible.

Below is a list of things to do. Feel free to contribute if any of them appeal to you and don't be afraid to ask for help! Make sure to read through contributing.md first before getting in too deep.

code maintenance

  • generalize components like buttons and sections for quick reusability
  • make classNames easier to read
  • write type declarations where needed so that it can build
    • component props
    • helper functions
  • standardize wording used in descriptions, etc.
  • remove unused imports (mdi icon paths, for example)
  • ensure responsiveness on every component
  • ensure accessibility on every component
  • ensure everything looks good in light and dark mode
  • test PWA and make sure it works offline


WebToys relies on several relatively modern browser APIs for some things to work. If something seems broken, make sure you're using the latest version of Firefox or Chrome.

If it's still broken across multiple browsers then I would greatly appreciate if you opened an issue!
