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.

AI coding assistant with full-codebase context
Uses Sourcegraph's Search API to pull context from local and remote repositories, so answers reference real APIs, symbols, and usage patterns across your code.
Ask questions about your code and attach specific files, symbols, remote repositories, or other artifacts using @ to give the assistant the exact context you want.
Suggests contextual code changes based on cursor movement and recent typing, alongside inline completions to speed up everyday editing.
Build, save, and share reusable prompts so common tasks and workflows can be standardized across a team.
