Onlook vs Bruno
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.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
About
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
