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 data masking and passwordless access for Rails console sessions
Sensitive keys, credentials, and PII are detected and masked in real time as Rails console output is printed, with zero setup and no data catalog to maintain.
Static keys and shared credentials are replaced by Google SSO plus MFA, with automated onboarding and off-boarding tied to user groups and console profiles.
Every console session is recorded, giving a searchable trail of who did what, when, and where for any operation performed in the console.
Approve a single command, a single reviewed file, or a time-boxed window from 10 minutes to 12 hours directly in Slack before the action runs.
