Onlook vs 100ms
Side-by-side comparison of AI visibility scores, market position, and capabilities
SF YC-backed open-source visual IDE editing live React/Next.js/Tailwind apps directly with code sync — "Cursor for designers"; bridging design-dev gap with in-browser component editing competing with Builder.io and Framer for AI-assisted visual development.
About
Onlook is a San Francisco-based open-source visual development tool — backed by Y Combinator — building the visual IDE for designers and developers who build React applications, enabling direct in-browser visual editing of running React/Next.js/Tailwind apps with real-time code synchronization — described as 'Cursor for designers.' Onlook allows users to start with a new app generated from a natural language prompt or import an existing Next.js and Tailwind CSS project, then design the live running interface directly (clicking, dragging, resizing, and styling components in the rendered browser preview) with every visual edit automatically written back to the actual source code — React component files and Tailwind class strings — not to a separate design spec that developers must re-implement.
100ms is a live audio/video infrastructure platform with SDKs for React, iOS, Android, and Flutter, providing programmable rooms, recording, and live streaming for web and mobile apps.
About
100ms is a live audio and video infrastructure platform that provides developers with SDKs and APIs for embedding real-time communication features — video rooms, audio spaces, live streams, and recording — into web and mobile applications. The platform is designed around a room-based model where developers programmatically create, configure, and manage video rooms through a REST API, with client SDKs for React, iOS, Android, Flutter, and React Native handling the media layer. This abstraction allows teams to build fully custom video experiences with their own UI without dealing with WebRTC internals, TURN server management, or media server infrastructure.
