Streamline

What is Streamline?

Streamline is a digital asset library that provides thousands of unified icons and illustrations designed as a cohesive visual system, made by Streamline HQ. The platform supplies designers, developers, and product teams with pre-built graphical assets that maintain consistent styling across projects, reducing the need to create assets from scratch or manage mismatched visual styles across applications.

The library contains icons organized by category and use case, along with accompanying illustrations that follow the same design language. Assets are available in multiple formats (SVG, PNG, PDF) and at various sizes, making them suitable for web interfaces, mobile applications, print materials, and presentation decks. The system emphasizes visual consistency by maintaining uniform stroke weights, corner radii, and color palettes across all included assets. Users can customize icons through color adjustments and sizing without losing fidelity, and the SVG format enables further editing in design tools like Figma, Adobe XD, or Illustrator. The platform supports integration into design workflows through Figma plugins and direct downloads, allowing teams to incorporate assets into their existing tools and processes.

Streamline operates on a freemium model, offering a limited selection of free assets alongside premium subscriptions that unlock the complete library and additional features like priority updates and commercial usage rights. The service targets UX designers, UI developers, product managers, and creative agencies seeking to accelerate design workflows while maintaining visual coherence. Teams using design systems benefit from the pre-organized, standardized nature of the library, which reduces decision-making overhead during prototyping and implementation phases. The platform serves both individual designers and enterprise teams, with pricing tiers scaled accordingly.
