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.
Open-source tools and libraries that make the command line glamorous
A terminal-based coding agent that connects your tools, code, and workflows to the LLM of your choice, available on macOS, Linux, Windows, and BSD.
The Go framework behind a large share of modern terminal interfaces, complemented by Lip Gloss for styling, Huh for forms, Bubbles for widgets, and Wish for SSH apps.
Small, focused tools including gum for shell scripts, glow for markdown, vhs for terminal GIFs, skate for key-value storage, and Pop for command-line email.
Coding-optimized, high-availability, cost-efficient hosting for open-source models, with a platform layer for production CLI workloads.
