## 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

## T3 Code

T3 Code is an open-source application for developers who juggle more than one AI coding agent. Instead of switching between terminals, editors and vendor dashboards, it provides one surface where threads with Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok can run side by side. Critically, the project does not resell model tokens: you plug in the credentials and subscriptions you already have, so your existing plan and quota remain yours. Models can even be switched mid-thread, letting you move a task to a different harness without losing conversation context.

**Pricing & Plans:** Free and open-source. There is no T3 Code subscription; you bring your own existing Claude Code, Codex, Cursor or similar subscription and pay those vendors directly.

- **Multi-Agent Orchestration:** Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
- **Bring Your Own Subscription:** No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
- **Git and PR Workflow:** Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
- **Forkable and Self-Hostable:** Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
- **Desktop and Mobile Access:** Available on macOS, Windows and Linux with iOS, Android and browser connect options for remote machines.

**Strengths:** Free and open source with no vendor subscription for the tool itself; One interface for several major coding agents instead of scattered terminals; Bring-your-own-subscription model with no token reselling or quota caps; Mobile and browser access plus Git, diff review and PR automation built in

**Limitations:** Requires your own paid agent subscriptions to be genuinely useful; Self-hosting and configuration are your responsibility, with community rather than vendor support; Rapidly evolving project means features and stability can shift between releases
