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.

Antidetect browser that keeps every account in its own fingerprint island
Each profile gets a distinct fingerprint configuration so accounts are not linked through browser signals, with extensive fingerprint parameters available to tune.
Manage IPv4 and IPv6 proxies from a central panel and pair them with RoxyIP's proxy pool so browser identity and IP identity stay independent.
Create profiles from templates in one click, sync windows to perform the same action across many profiles, and drive everything through API calls.
Launch tasks with a single command while AI handles planning, orchestration and autonomous execution, with MCP-style connectivity for agent workflows.
