<p>[Free + Open-source] Cyber are the icons of the future. This retrofuturistic family only uses straight lines and sharp angles, reflecting a fascinating personality with obvious cyberpunk vibes.&nbsp;The Line style is perfect for projects that prioritize simplicity, seamlessly adapting to both light and dark backgrounds. It also allows you to customize the line thickness. All Cyber Line icons are designed on a 24px grid with a 1 px stroke. Licensed under the Creative Commons - CC BY 4.0</p>

<p>Cyber is one of our most challenging icon sets: no curves, only straight lines and sharp angles. Inspired by sci-fi aesthetics, it’s perfect for bold brands and futuristic tech.</p>

### **one sentence positioning**

The most mechanically extreme icon family available — zero curves, straight lines only, dark navy default, built for futuristic and high-tech interfaces.

---

### **what it signals**

Advanced technology, precision engineering, system control, architectural rigour, futuristic thinking.

---

### **best fit when**

- the interface must feel engineered and unmistakably high-tech with no compromise
- visual distinctiveness from standard rounded icon sets is a strategic requirement
- the product identity is built on AI, cybersecurity, infrastructure, robotics, or sci-fi UI

---

### **avoid when**

- the product needs any warmth, softness, or mainstream legibility
- a neutral UI language that adapts across audiences is the goal
- organic, human, or playful tone is needed

---

### **core visual rules**

- geometry: faceted, angular, polygonal — circles are approximated with straight segments; no true arcs exist anywhere
- terminals: sharp — all paths terminate at a hard angle, never softened
- corner language: sharp, faceted, straight-line-only construction throughout
- curves: none — the defining rule is zero Bézier curves in any icon
- detail density: low to medium
- silhouette: high visual energy — the absence of curves creates constant angular tension
- emotional tension: high — the sharp transitions produce more visual energy than any other family in this review

---

### **variants and hierarchy**

Cyber Line (1px, dark navy)

- Primary navigation and UI controls in high-tech products; the schematic-drawing aesthetic at its most direct

Cyber Duotone (1px, three-layer)

- Dark navy stroke + light blue tint fill + white base; feature sections and documentation with colour differentiation

**line/solid pairing rule** Cyber does not have a conventional solid sub-style. The Duotone three-layer construction serves the colour hierarchy role. Use Line for standard contexts and Duotone where category colour differentiation is needed.

---

### **small-size behavior**

- recommended minimum size: 16px
- best range: 16–48px
- notes: The straight-line joins create sharp termination points that can read as broken pixels on non-retina screens below 16px — the angular geometry requires sufficient physical pixel resolution to render cleanly.

---

### **motion behavior**

- strengths: crisp rotation perfectly suited to angular geometry, stable scaling, mechanical-feeling stroke animations
- ideal motion contexts: loading states in technical dashboards, system feedback loops, control panel interactions, data transition animations, hover states in developer tooling

---

### **typography pairing**

Geometric / futuristic sans (maximum cohesion)

- Space Grotesk, Eurostile, Bank Gothic, Aeonik, Barlow Condensed, Orbitron (display only)

Neutral UI sans (safe balance)

- IBM Plex Sans, Neue Haas Grotesk, Source Sans 3, Helvetica Now

Mono / terminal (control-surface feel)

- IBM Plex Mono, JetBrains Mono, Geist Mono, Space Mono, Source Code Pro

**type alignment rule** Prefer typefaces with geometric discipline, technical clarity, low softness, and strong stroke consistency. The type should look like it was built with a ruler — fonts where the 'a', 'e', and 'g' have visible calligraphic influence are wrong for Cyber.

**typefaces to avoid** Nunito, Poppins, Inter, Lato — humanist warmth directly contradicts the cold mechanical precision. Rounded terminal fonts of any weight create a personality mismatch with the straight-line construction.

---

### **mixing guidance**

Recommended with

- Sharp — both carry geometric technical authority; separate by specificity (Cyber for extreme tech, Sharp for enterprise general)

Possible with normalization

- Nova — both work for technical products; isolate Cyber to the most distinctive surfaces
- Core — technically compatible; keep Cyber for hero and identity moments, Core for utility controls

Avoid mixing with

- Freehand — the most extreme possible contrast in this library
- Plump — zero visual compatibility
- Flex — organic curves directly negate the zero-curve construction rule

**normalization rules when mixing**

- keep Cyber consistent within primary navigation and hero UI surfaces
- never mix Cyber with a rounded family in the same component or row
- if mixing with a neutral family (Core, Nova), isolate by surface — Cyber for the product's strongest brand moments, neutral family for utility

---

### **primary use cases**

- AI and machine learning product interfaces
- developer platforms and infrastructure tooling
- cybersecurity dashboards and security operations products
- crypto and Web3 interfaces
- data infrastructure and robotics software UIs
- sci-fi and gaming UI contexts

---

### **secondary use cases**

- high-tech marketing websites and futuristic brand systems
- control panels and monitoring tools
- advanced analytics and experimental design systems
