Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

The security brain that keeps AI coding agents inside your rules
Intercepts dangerous commands and edits - raw secret reads, unscoped DELETE statements, writes to protected directories - before the AI agent is allowed to execute them.
Reviews each proposed change for SQL injection, hardcoded API keys, personal data leaking into logs, public cloud buckets, vulnerable dependency versions and compromised CI action tags.
Derives the review rules your senior engineers repeat from real code evidence, then requires human approval before a rule is enforced across every agent.
Builds a map of your services so the guard knows what callers, callees and downstream jobs an agent is about to affect before a line is written.
