Tempo vs 100ms
Side-by-side comparison of AI visibility scores, market position, and capabilities
Toronto AI React design-engineering platform integrating with existing production codebases for 10x faster UI building; YC $5M Oct 2025 seed competing with Cursor and Vercel v0 for design-to-code tooling.
About
Tempo is a Toronto-based AI-powered design-engineering platform — backed by Y Combinator with $5 million in seed funding raised in October 2025 from YC, Golden Ventures, Box Group, Webflow Ventures, iNovia, and General Catalyst — providing a visual code collaboration environment where product managers, designers, and engineers can build React UIs 10x faster by combining familiar design tool UX with full IDE functionality and production codebase integration. Founded in 2023, Tempo differentiates from AI coding tools (Cursor, GitHub Copilot) that generate new codebases by integrating seamlessly with existing React production code — enabling teams to modify, extend, and build on live codebases visually without the "generate from scratch" workflow that can't scale to complex existing products.
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.
