SaaS — Developer Tool Landing
A dark, terminal-flavored landing page for a fictional developer platform, pairing a clean sans interface with monospace accents. It features a copy-able install command, a self-typing terminal that replays a live deploy, feature tiles aimed at engineers, a curl/JavaScript/Python code-sample tab switcher with one-click copy, animated GitHub-stars social proof with a working star toggle, and a docs call to action — all self-contained vanilla HTML, CSS, and JavaScript.

</html>Developer Tool Landing
A credible, engineer-facing landing page for Pulsar, a fictional developer platform for shipping backend APIs. The dark surface, terminal accent green, and mix of Inter and JetBrains Mono set a technical, trustworthy tone. The hero leads with a copy-able install command and an animated terminal that types out a realistic pulsar deploy session on a loop, with a blinking cursor.
Below the hero, feature tiles speak directly to developers — cold starts, tracing, instant rollbacks, secrets and SSO, preview environments, and typed SDKs. A quickstart section centers on a code-sample card with a cURL / JavaScript / Python tab switcher (keyboard-navigable with arrow keys) and a one-click copy button that grabs the active sample. Social proof comes from an open-source GitHub card whose star, fork, and “used by” counters animate into view, plus a working Star toggle that bumps the count in both the card and the nav.
Every interaction runs on dependency-free vanilla JavaScript: a toast() helper, clipboard copy with a textarea fallback, an IntersectionObserver-driven counter, and a prefers-reduced-motion guard that renders the terminal statically. The layout collapses gracefully to a single column on small screens, and all controls have visible focus rings.
Illustrative SaaS UI only — fictional product, metrics, and billing. No real backend.
