Dev-Tool Landing Page

The brief we build from

This is the exact instruction PromptUI starts with. You can change every word of it before or after the first build.

Build the marketing landing page for Flagstone, our feature-flag and edge-config platform for engineering teams — I'll host it at flagstone.dev. I want it to feel like a serious developer tool, not another purple-gradient SaaS page: near-black ground, tight display type, and exactly one accent color, electric cyan, with a soft violet glow used only behind the hero. The hero needs a sharp headline, one-line subcopy, two CTAs, and a real-looking ~6-line code snippet showing our SDK checking a flag like checkout-v2. Under that, show a row of honest capability claims — sub-millisecond edge evaluation, an instant kill switch — with no fake customer logos or invented counts, then a six-card feature grid and a three-step how-it-works. I really want an interactive flag demo: a few real toggle switches that visibly update a live JSON config panel sitting right beside them. Close it out with three pricing tiers that have a monthly/annual toggle, an accordion FAQ, a final call-to-action band, and a footer.
