Polyglot is a Tampermonkey userscript with small, opt-in quality-of-life improvements for Codewars. It focuses on making everyday workflows faster by surfacing information that's already there, smoothing out UI friction, and adding a few "why isn't this built-in?" conveniences.
- Install the Tampermonkey browser extension (from your browser's extension/add-ons store).
- Download the script from the latest release: https://github.com/hobovsky/polyglot/releases/latest/download/polyglot.js
- In Tampermonkey, create a new userscript and paste in the contents of
polyglot.js(or import the downloaded file if your Tampermonkey/browser supports it). - If your browser blocks userscripts by default, check Tampermonkey's FAQ / your browser's extension settings (sometimes called "developer mode").
That's it - Tampermonkey should pick up updates automatically (depending on your Tampermonkey settings).
Click a feature to jump to details + a screenshot.
- Copy buttons on code blocks - copy code without fighting scrollbars.
- Raw markdown toggle - view the original markdown (helpful when a post is missing code blocks).
- Attempted languages in discourse - see which languages the post author attempted.
- Beta kata: rank vote breakdown - see difficulty vote distribution, not just an average.
- Rank-up notifications - get a heads-up when you climb.
- Solution timestamps - add missing chronology context.
- Custom navigation links - pin your own deep links in the sidebar.
- Leaderboards improvements - default to "Solved kata" + auto-scroll to you.
- CodeMirror editor tweaks - configure tabs, indentation, and a few other editor behaviors.
- Solutions tabbed by language - browse solutions faster when you use multiple languages.
- Past solutions tabbed by language - same idea as above, but inside the kata trainer.
- Always-visible spoiler toggle (discourse) - no more misclicks on invisible controls.
Copy buttons on code blocks - copy code in one click
- Adds "copy to clipboard" controls on code blocks across Codewars (solutions, discourse, kata descriptions, comments).
- Saves a bunch of annoying text selection in scrollable code panes.
Raw markdown toggle - view the original markdown
- Adds a toggle that switches between rendered markdown and the raw markdown source.
- Handy when code blocks are missing or formatting is broken: raw markdown preserves indentation and line breaks.
Attempted languages in discourse - see which languages the author attempted
- Shows which languages a user attempted a kata in under their discourse posts.
- Indicates which of those solutions are viewable to you (based on Codewars visibility rules).
- Some entries may be non-clickable if you're not eligible to view that solution in that language.
Beta kata: rank vote breakdown - see the vote distribution
- Displays a visual breakdown (histogram) of difficulty votes for beta kata.
- Helps approvers/authors see consensus vs. polarization instead of guessing from min/max/average.
- Read-only: it doesn't modify votes or approval logic.
Rank-up notifications - get a heads-up when you climb
- Shows a notification when you rank up (for leaderboards Polyglot tracks).
- Avoids the "did that submission change anything?" manual checking loop.
Solution timestamps - add missing chronology
- Displays timestamps for solution groups to give more context when browsing.
- Useful when you're trying to understand "what changed when" across submissions.
Custom navigation links - pin your deep links
- Lets you pin frequently used internal pages (filtered searches, collections, kata lists) into the sidebar.
- Treats Codewars more like a daily workspace than a site you "browse".
Leaderboards improvements - less navigation, more signal
- Defaults leaderboards to "Solved kata" (instead of "Overall").
- Automatically scrolls leaderboards to show your row/position.
CodeMirror editor tweaks - configure tabs and indentation
- Lets you configure a few CodeMirror editor behaviors (e.g. tab size, tabs vs spaces, auto-closing brackets/parentheses).
Solutions tabbed by language - find the language you want fast
- Groups solutions by programming language and shows them as tabs.
- Makes multi-language profiles much easier to navigate.
Past solutions tabbed by language - faster reuse in the kata trainer
- Applies language tabs to "My past solutions" inside the kata trainer.
- Helps when you revisit a kata in multiple languages (or have a long solution history).
Always-visible spoiler toggle (discourse) - no more invisible controls
- Makes the "Spoiler" toggle under discourse posts permanently visible.
- Reduces accidental spoiler/unspoiler clicks caused by hover-only controls.
Disable or remove the script in Tampermonkey.
Issues and PRs are welcome.
- For bug reports, the most helpful things are: page URL, browser, Tampermonkey version, steps to reproduce, and any console errors.
- Design preference: features should be opt-in (configurable on/off), so people can keep their Codewars UI the way they like it.
