## Code Arena

Code Arena is built for developers who want evidence rather than marketing claims when choosing a coding model. Instead of reading benchmark tables, you prompt multiple frontier models with the same request, watch them construct web apps and sites in real time, and then judge the output on accuracy, logic, and code quality. The 'battle' format mirrors the popular blind-comparison leaderboard approach, adapted specifically for software generation tasks.

The platform is designed to handle multi-file projects rather than single snippets, so the comparisons reflect the messy reality of real development work: routing, component structure, styling, and state management all have to hold together. Results are surfaced through a leaderboard so you can see which models are consistently favoured by the community over time.

Because the tool is free to use and browser-based, it works well as a quick sanity check before committing a paid subscription or API budget to a particular model, and as a way to keep a finger on the pulse of how fast the coding-model landscape is moving.

**Pricing & Plans:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**Strengths:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**Limitations:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## FileChangeCategorizer

Reviewing a pull request with hundreds of changed files is mostly a sorting problem. FileChangeCategorizer tackles that problem inside the browser: you define matching rules (for example by path, extension, or folder), and the extension applies those rules to the file list of a commit or pull request so that related changes sit together under clear labels instead of appearing as one long alphabetical list.

Because it runs as a Chrome extension, there is nothing to install on your build servers and no repository configuration to commit. It follows you across every GitHub repository you have access to, which makes it convenient for reviewers who jump between projects, open-source contributions, and client repos in the same session.

The project is published by an individual developer, has a single ~0.0.1 release from May 2024, and a small installed base. It is best treated as a focused convenience utility: install it if repetitive file sorting in pull request reviews is a real part of your day, and keep expectations modest about updates, support, and enterprise-grade features. The extension requests access to website content in order to read the file lists on GitHub pages, and its published privacy disclosure states data is not sold to third parties.

**Pricing & Plans:** Free to install from the Chrome Web Store. There is no paid tier, subscription, or in-app purchase attached to the extension.

- **Rule-based file categorization:** Define your own matching rules and let the extension sort changed files in commits and pull requests into labelled groups automatically.
- **Works directly on GitHub pages:** The categorization is applied inside the GitHub commit and pull request views you already use, with no dashboard to switch to.
- **Zero repository configuration:** Nothing is committed to your codebase and no CI setup is required, because everything runs in the browser extension.
- **Useful for large pull request diffs:** Groups of related files make sprawling diffs easier to scan and review in a logical order.
- **Simple, single-purpose design:** It does one job and stays out of the way, which keeps the mental overhead of adopting it very low.

**Strengths:** Free to install with no account required; Cuts visual noise in large pull request file lists; No repository or CI changes needed; Works on any GitHub repository you can already open

**Limitations:** Very small user base and only a single early release, so long-term maintenance is uncertain; Only useful if you regularly review large, multi-file pull requests on GitHub; Categories must be configured by hand as rules; there is no built-in smart detection; Requests access to website content in order to read GitHub pages
