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.

Local-first AI desktop app to run and monitor your Linux server fleet
Describe the outcome in plain English and CtrlOps drafts the shell command; nothing runs until you review and approve it.
Keep your whole fleet in one window with named aliases, per-server SSH keys, and an access scan showing who can log in and who holds sudo.
Fill a single form with your repo, environment variables, and domain, and CtrlOps provisions the app with Nginx, SSL, and PM2.
Watch CPU, memory, disk, and network in real time, and find, search, or tail logs across hosts without hunting for paths.
