Adora

Adora automatically captures every screen, modal, and user journey in your live product without manual event tagging, building a continuously-updated visual library of what your app actually looks like in production. AI watches for usability issues 24/7 and links findings directly to the affected screens. Founded by ex-Canva execs, backed by Blackbird Ventures with a $9.9M seed, and used by teams at Canva, Notion, and Replit.

Dessn

Dessn lets product teams design directly in their production codebase without opening an IDE. Give it read access to your repo and it extracts your design language — components, tokens, typography — then builds a design environment your whole team can use for prototyping and handoff. The result is developer-ready code from day one because designs are made in the actual production context.

Onlook

Open-source visual code editor for React — edit Next.js + Tailwind applications with a Figma-like interface that writes changes directly to your codebase in real time. Visual edits map to actual JSX via unique element identifiers; Figma imports convert to working components. Positions itself as 'Cursor for designers' with changes becoming PRs, not handoff specs. Apache 2.0, self-hostable.

Sketch

The original modern UI design tool — a native macOS app that pioneered the design system era. The 2025 Copenhagen update is its biggest UI overhaul since 2020: contextual toolbar, rewritten Inspector, wrapping Stacks, and macOS Tahoe's Liquid Glass aesthetic. Loyal community but faces headwinds from Figma's browser-based collaboration and AI features.
