in the wild.

Every site here has been read, screenshotted and scored against 16 canonical tropes. The score is not a judgement of quality — plenty of high scorers convert fine. It measures one thing: how much of the layout was decided before anyone knew what was being sold.

Rover

Fictional · calibration entry

Uber for dogs. Where the dogs are the driver.

The reference specimen. A perfect 16/16 — the only entry in the registry to match every trope in the taxonomy, which is why it ships as the calibration standard rather than a submission. The hero reads 'Ship the journey.' at weight 100, with 'journey' in italic Georgia carrying the gradient. Four boxes: Fetch, Sit, Stay, Roll Over. The pricing page has three tiers, the middle one badged Most Popular, and no tier explains who is being charged — the passenger, or the dog. An FAQ nobody asked answers 'Is my driver insured?' with 'Every Rover is a very good boy.' The stats band claims 99.99% uptime and 2M+ tails wagged. Neither is instrumented. Both are gradient-filled.

Standout detail. The 'Meet your driver' section uses emoji as iconography — 🐕 🦴 🚗 🐾 — and is the only place on the site where the product is explained. The Book a ride button has no handler.

Synthesis

Fictional · calibration entry

The AI-native workspace for modern teams.

A workspace product that never says what you would put in the workspace. The headline is 'Think together, faster.' at weight 200, 96px, with 'together' in italic serif. Below it, a bento grid of eleven cards showing features that are all named after verbs. Loses two points for having five feature boxes rather than four — a genuine deviation — and for a light mode that is not merely present but appears to have been tested.

Standout detail. The 'Integrations' section shows twenty-four logos at 40% opacity. Nine of them are the same shape rotated.

Halcyon

Fictional · calibration entry

The operating system for ambition.

Sits at the indigo end of the gradient, which reads as more serious and is not. 'The operating system for ambition' is the entire value proposition; the word 'ambition' does the work that a product description would otherwise have to. Four boxes, correctly. Numbered steps 01–03 describing a process that is not sequential. No pricing page at all — a Contact sales button that opens nothing, which costs it the three-tier trope but earns dead-buttons twice over.

Standout detail. The founder's letter in the footer is signed with a generated signature font and the title 'Founder & Chief Ambition Officer'.

Peppercorn

Fictional · calibration entry

Payroll, reimagined.

Evidence that the aesthetic has reached regulated industries. A payroll product — a category where trust is the entire purchase — presented in weight-200 type over an ambient purple glow, with a hero that reads 'Pay people. Beautifully.' Scores lower than the rest of the registry, but only because fintech compliance forced real numbers into the stats band and real logos into the trust row. Everything the regulator did not touch is textbook.

Standout detail. The security page uses the same emoji iconography as the features grid. SOC 2 Type II is represented by 🔒.

Review the diff before it goes up — the summary is written by a model that has just looked at a lot of gradients, and it gets enthusiastic.
