Kernel

Above the fold

The giant black wordmark sits above six evenly spaced lowercase links, from "platform" to "sign in / up", with a hairline rule beneath. The two-line headline in light Inter carries two small outlined badges, "soc2" and "hipaa", at its end. A one-sentence subhead precedes a filled "start building" and an outlined "book demo". At the base, "loved by 11,000+ teams building agents" introduces six customer logos in one row.

Feature carousel and benchmark

A row of cards runs off the right edge: "sandboxed chromium" on a green panel, "stealth" with a cowboy-hatted robot in a grid of solved captcha tiles, then "managed auth". Each pairs a small label with one sentence, such as "we spin up cloud browsers in <30ms for agents to act on websites". "the kernel difference" follows with "throughput" and "cold start" toggles and three horizontal bars, green "kernel" longest at "6.43 actions/sec".

Use-case tabs, stories and partners

Four boxed tabs, "qa", "healthcare", "e-commerce" and "gtm", sit over a split panel: a green illustration of arrow cursors and "bug found" tags on the left, a large quote from Stably on the right with an underlined "build qa agents" link. Two bordered story cards follow, "the prompting company" and "effective", each with a logo frame and "read story". "friends of kernel" lays out four logo tiles at staggered heights.

Closing section and footer

A small robot mascot tops the centred line "give your agent the internet", with a black "copy prompt" button and a "see cookbooks" link below. The footer puts an outlined stacked monogram on the left and prose columns headed "articles", "follow" and "legal", where a struck-through "twitter" precedes "x". Four link lists follow, among them "developers" and "company", ending in a small copyright line.

On mobile

At 390px the page grows to 7962 pixels. The headline breaks across five lines. The logos wrap into three rows and the carousel shows one card with the next peeking in. The benchmark bars stack under their caption, the use-case tabs scroll sideways, and story and partner cards run one per row. The footer moves "legal" to the top and pairs link lists two by two.

Worth borrowing

• Setting all copy, buttons included, in light lowercase lets a heavy logotype carry the brand on its own.
• Showing a competitor benchmark as three labelled bars, with only the winner in colour, makes the speed claim readable at a glance.
• Writing footer columns as sentences, such as a struck-through "twitter" beside "x", gives routine links a voice.
