GrowwwKit: 20+ Vector Illustration Packs for Websites and Apps
GrowwwKit is a prolific illustration studio behind packs like Aventine, Workaholics, and Polydrome. Here's a look at their full collection on UI8, plus 3D alternatives from ThreeDee if you want to level up.
If you've browsed UI8 for illustration packs, you've almost certainly come across GrowwwKit. They're one of the most prolific illustration studios on the platform, with over 20 unique packs covering everything from corporate office scenes to vibrant street-style characters. Their signature? 100% vector, well-organised files, and a consistent quality level that makes it easy to mix packs across a single project.
What is GrowwwKit?
GrowwwKit is a design studio that specialises in illustration packs for websites, desktop apps, and mobile apps. All their work is sold through UI8 and follows a consistent production standard: fully scalable vectors, named and organised layers, and formats like AI, SVG, and PNG. Their packs range from flat and minimal to bold and character-driven, giving design teams a wide palette to choose from.
The character-driven packs
Several GrowwwKit packs centre on memorable character illustration systems. Workaholics features 20 office-themed vector illustrations with fun characters. Office Dave and Desk Dudes cover similar territory with distinct visual styles — both are great for SaaS landing pages and internal tools. Jane and The Carltons offer more lifestyle-oriented characters, while Familiar Bunch and Lil Helpers bring a playful, rounded aesthetic that works well for consumer apps.
Scene and environment packs
Beyond characters, GrowwwKit produces excellent scene illustrations. Aventine delivers 24 high-quality scenes with customisable swatches. Springtale and The Townies offer different environmental styles — suburban warmth and urban energy respectively. Cityscapes-style packs like Metrorama bring metropolitan scenes to life. And Isotopia stands out with a stylish isometric approach that's perfect for feature sections and process diagrams.
Tech and startup packs
For tech products specifically, Laboratorium focuses on techie illustrations available as AI, SVG, and PNG. Circuit targets a similar audience with clean vector tech scenes. Dreamwork is a versatile pack available in multiple formats, and GrowwwKit even offers Dreamwork Animations — SVG/HTML animations with After Effects source files for teams that need motion. Tech Peeps rounds out the tech offering with character-focused illustrations built for software products.
The bold and vibrant side
Not everything GrowwwKit makes is corporate. Fundango is a set of 18 fun, energetic, and vibrant illustrations with a completely different energy — great for creative agencies and entertainment products. Lubo covers everyday work and life situations with a simple, stylish approach. And Polydrome brings a geometric, colourful style that stands out from typical flat illustrations.
Free packs to try
GrowwwKit offers two free packs to get started. Phonies includes 8 free character illustrations, and Neighbour Larry provides 14 free illustrations — both targeting startups, brands, and agencies. These are a solid way to test the GrowwwKit style before committing to a paid pack. There's also a paid sequel, Phonies 2, if you like what you see.
Want to go 3D? Try ThreeDee
GrowwwKit's strength is polished 2D vector illustration. But if your project needs the depth and premium feel of 3D, the ThreeDee ecosystem is the natural upgrade. Where GrowwwKit gives you flat characters and scenes, ThreeDee gives you fully rigged 3D characters you can pose, recolour, and render from any angle in Blender.
Characterz offers over 2 billion combinations of modular 3D cartoon characters — bodies, heads, outfits, poses, and accessories. Headz provides 400,000+ head variations as an Apple Memoji alternative. Illustrationz is a massive multi-purpose 3D library with 167 million+ combinations covering adults, kids, elders, and pets. And Avatarz gives you upper-body 3D cartoon avatars perfect for user profiles and team pages.
The key advantage? All ThreeDee packs share the same visual style, so you can mix characters from Characterz with heads from Headz and pets from Petz for a unified look. Every pack ships with Blender source files and pre-rendered PNGs, so you don't need to be a 3D artist to use them.
GrowwwKit vs ThreeDee: which to choose?
If you need lightweight, flat vector illustrations that drop into Figma or Sketch instantly — GrowwwKit is excellent. Their packs load fast, scale perfectly, and the vector format means tiny file sizes. If you want illustrations that feel more premium, have depth, and can be customised in 3D — ThreeDee is the way to go. Many teams use both: GrowwwKit vectors for blog posts and documentation, ThreeDee 3D renders for hero sections and marketing pages.
