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.
Secure-by-default system prompts that stop AI assistants from writing vulnerable code
Prompt packs tailored to a language and framework — Python, React, Spring Boot, Next.js, Django and 50+ more — that encode secure coding rules rather than generic advice.
Prompts cover AI security, authentication and authorization, cryptography, input validation, web and API security, cloud and mobile security across 30+ topics.
Installs into Claude Code, Cursor, Windsurf, GitHub Copilot, OpenAI Codex, Aider, JetBrains AI, Amazon Q and Cline / Roo Code without replacing your editor or workflow.
Every prompt is written around the guidance of Jim Manico, co-leader of the OWASP Cheat Sheet Series and a contributor to ASVS and AISVS.
