## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**料金とプラン:** 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.

**強み:** 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

**制約・デメリット:** 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

## ML.ai

ML.ai is a coding agent that ships whole tasks rather than autocompleting lines. Hand it an issue and it reads the repo, writes a task plan, edits the code, runs your tests and opens a pull request - routing each step to the model that fits it while showing every diff before anything is written to disk.

**料金とプラン:** Paid, per seat. Every plan includes the full agent and the differentiator is concurrency - how many jobs run in parallel - rather than a token budget. Individual plans target solo builders, while Team and Enterprise tiers add more parallel jobs; enterprise buyers can contact sales for a quote. Long-running jobs are not cut off partway by credit exhaustion.

- **End-to-end task completion:** Give it an issue and it reproduces the bug, edits the code, runs your tests and opens a pull request while you focus on decisions.
- **Plan-and-approve scope guard:** The agent proposes a task list and names the files it expects to change. You select the tasks, and edits outside the declared scope stop and ask first.
- **Model routing and effort levels:** Each step of a task is routed to the model that fits it, with the vendor abstracted behind an effort setting and a stated outcome.
- **Parallel sandboxed jobs:** Launch many jobs across projects at the same time. Each agent runs in its own sandbox and reports back with a reviewable diff.
- **App, IDE and CLI in one account:** The same account connects a desktop app for macOS and Windows, extensions for VS Code and JetBrains, and a terminal CLI via a single install script.

**強み:** Completes whole tasks including tests and PR creation; Scope guard halts edits outside declared files; Per-seat pricing removes mid-task budget stops; Same agent in desktop app, IDE and CLI

**制約・デメリット:** Per-seat pricing is less flexible than pay-per-token for very occasional users; Claimed benchmark numbers come from the vendor's own evaluation runs; Full agent capability requires the desktop app, IDE extension or CLI rather than a browser-only workflow
