Figma Make: prompt-to-app with your design system as context, whose loop ends in a hosted URL rather than your repo
Figma Make is the only prompt-to-app tool whose first context is the design files you already maintain: attach team libraries, components, variables, and styles, then package them into a reusable Make kit. Editing works by pointing rather than describing, via the edit tool on individual elements, the draw tool for marked-up regions, and per-element annotations. But the loop terminates in a Figma-hosted URL (AWS plus Cloudflare), not your GitHub repo: there is a code editor and code export, yet no PR-to-CI path. Cost runs on credits, with 3,000 a month for a Professional Full seat, roughly 75+ per mid-complexity app, and plan mode billed as a separate action, so the quota counts conversations rather than apps. Publishing means public with no access restriction, the preview cannot reach camera or microphone, and third-party content rights are yours to clear.
