Value props

68Fair

Title, subtitle, hero — do they sell the product's true value?

s2.dev’s headline sellsStreams as a cloud storage primitiveThe serverless API for unlimited, durable, real-time streams.

Working

  • Precise positioning for dev audience
  • Subhead names durable, real-time, serverless
  • YC badge and open-source s2-lite add proof

Could improve

  • No numbers: latency, scale, or price
  • Hero gradient decorates, shows nothing
  • No felt outcome for the developer

CTA

72Fair

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Problems

  • generic label, no payoff named
  • small vs. oversized headline
  • playground demoted to secondary
  • competes with nav 'Dashboard' button

Mobile web

72Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Get started button — Desktop-proportioned button squeezed beside the secondary CTA instead of a full-width thumb target.
  2. Hero headline — Type scaled down too little — "cloud" clips against the right edge of the viewport.

Information hierarchy

82Strong

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture1234
  1. Dashboard button — Same solid-black weight as "Get started", creating two competing visual peaks in the fold.
  2. Announcement banner — Seed-round link occupies the top scan line and pulls first attention away from the conversion path.
  3. s2-lite link row — Arrowed outbound link sits directly under the CTA pair, catching visitors mid-decision.
  4. Try the playground button — Bordered secondary sits at equal size beside "Get started", diluting the single-action read.
