Describe your idea in chat and Lovable turns it into a working app or website
Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.

An AI production engineer that watches every deploy and fixes issues before customers notice
Struct reads each pull request and generates the monitors and metrics needed to verify that change in production, with no code changes required, then baselines alert thresholds automatically after deploy.
Every production alert is triaged automatically. Irrelevant ones are pruned, flappy ones are tuned as prod changes, and only real issues are escalated — each arriving with an owner, impact analysis and root cause.
When Struct is confident, it can open a fix PR on its own. You can also connect your own coding agent or software factory and let Struct dispatch and coordinate the remediation.
Struct accumulates context from your repositories, past incidents, alerts, fixes and team feedback, so guidance given once — such as never holding a database connection across a sleep — is remembered and applied to future PRs.
