Use tool ↗About Kombai
Kombai is a frontend-specialist coding agent: it generates page designs as editable HTML blocks on a canvas, then produces code matched to your framework and conventions, with point-and-click visual editing of the rendered result. It ships as extensions for VS Code, Cursor and other editors plus desktop apps for macOS, Windows and Linux, and reports over 500K installs with enterprise users like Adobe and Microsoft. A free plan drips 300 credits a month; Pro is $20/month and team seats $40, all metered in credits with rollover. Backend work stays yours — it deliberately stops at the frontend.

Pros & cons of Kombai
A rare agent that treats frontend as a design-plus-code problem: canvas designs, stack-aware code output and visual editing inside the IDE you already use. The catch is that it is frontend-only and credit-metered, so it complements rather than replaces a general coding assistant, and heavy use pushes you toward team pooling.
Pros
- Designs arrive as editable HTML blocks, not flat mockups
- Runs inside VS Code, Cursor and other editors plus its own desktop apps
- Free tier renews credits daily, so evaluation is genuinely ongoing
- SOC2 compliance and no training on user data on paid plans
Cons
- Scope ends at the frontend; everything else needs other tools
- Credit metering on each generation makes costs usage-dependent
- No public API for pipeline automation
Best for
- Frontend teams converting designs into stack-consistent components
- Developers who want visual tweaking of rendered UI instead of prompt loops
- Enterprises standardizing UI output across shared design systems
Not for
- Full-stack generation including APIs and databases
- Teams that want an open-source or self-hosted agent
Watch out: Credits meter every generation and design pass; sustained daily use on Pro may force an upgrade to pooled Team credits.
