Precise near-black product UI: hairline borders, a faint indigo spotlight, gradient-edged highlights and tight medium-weight Inter.
Design keywords
Say these words to ask for this style.
Linear-style dark SaaS is the look of modern developer and productivity tools. Everything sits on #08090A with 1px rgba(255,255,255,.08) hairlines instead of shadows; a soft indigo radial glow lights the top of the page like a spotlight, and only the most important surfaces get a gradient border that catches the light. Type is Inter at medium weight with tight negative tracking and gradient-faded headlines, density is high, statuses are tiny coloured dots, and keyboard shortcuts (⌘K) appear right in the UI. Calm, exact, engineered.
Best for
- Developer tools and B2B SaaS
- Issue trackers, CI/CD and infra products
- AI products aimed at professionals
- Product launch and changelog pages
Avoid for
- Consumer brands that need warmth or colour
- Older or low-vision audiences (low contrast greys)
- Content sites with lots of imagery
✓ Do
- Use 1px rgba(255,255,255,0.08) hairlines everywhere and no drop shadows on resting cards
- Keep one faint indigo (#5E6AD2) radial glow per view and a gradient border only on the hero element
- Set Inter at 500 with −0.03em tracking for headings, 13–14px for dense UI text
✕ Don't
- Don’t add colourful gradients or blobs — the colour is a whisper
- Don’t use big radii (>16px) or pill-shaped cards
- Don’t use bold 700+ headlines or wide letter-spacing
Not to be confused with
On mobile
Keep the hairline grouped lists and 13–15px type; the tab bar is a blurred near-black bar with a hairline top, and only the featured card gets the gradient border and indigo glow.
