## 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

## Extrapolate

Extrapolate is a lightweight, browser-based AI app focused on one very specific creative use case: face aging. You upload a photo of yourself, the service runs it through a generative model trained on faces, and it returns transformed versions of that image showing you at older ages — 10 years ahead, 20 years ahead, and even into your nineties. The homepage is built around a single clear call to action, so there is essentially no learning curve: choose a photo, wait for processing, and review the output.

Results are collected in a personal gallery so you can compare multiple generations side by side or revisit earlier attempts. The site reports hundreds of thousands of photos generated, which suggests an established, actively used consumer product rather than an experimental demo. Everything runs in the browser, and there is no software to install.

Because the tool touches personal photographs, the team addresses privacy directly in its FAQ, covering how the service works, whether it is safe to upload a picture, and how to delete your account and its data. Note that aging results are AI interpretations and are meant for fun and curiosity rather than any scientific or medical purpose.

**Pricing & Plans:** Advertised as free to use; the site's FAQ mentions a trial option, and no published paid tiers were found on the live site at the time of review.

- **One-photo face aging:** Upload a single portrait and let the AI generate older versions of your face without any manual editing or masking.
- **Multiple age targets:** Preview yourself roughly 10, 20, or many more years into the future to compare how different time horizons change the result.
- **Personal results gallery:** Every generation is stored in your own gallery so you can revisit, compare, and share previous transformations.
- **Browser-based workflow:** The whole experience runs in your web browser on desktop or mobile, with nothing to download or install.
- **Privacy and account controls:** The FAQ documents data safety questions and explains how to delete your account, giving users a way to remove their photos and results.

**Strengths:** Extremely simple, single-purpose workflow that needs no editing skills; Generates results quickly from just one uploaded photo; Results are saved to a personal gallery for easy comparison and reuse; Privacy and account-deletion questions are addressed in the site FAQ

**Limitations:** Limited to face aging, so it cannot handle general photo editing or retouching; Output quality depends heavily on the lighting, angle, and resolution of your source photo; AI aging is an artistic approximation rather than an accurate prediction
