Tempo Labs

AI design tool that edits React in your codebase

paidopen sourceupdated Aug 16, 2026

Tempo Labs is a YC-backed AI design and prototyping tool that generates and edits React code directly within a developer's existing codebase, maintaining project styles and conventions. Unlike tools that produce standalone code, Tempo supports both greenfield and brownfield projects, understanding existing component libraries, theme systems, and coding patterns to generate code that fits naturally.

Tempo Labs bridges the gap between design tools and code editors by allowing developers to visually design and prototype React interfaces that are generated directly into their existing project structure. The AI understands the project's existing component library, design tokens, and styling patterns, ensuring generated code follows established conventions rather than introducing inconsistent patterns.

The brownfield support is a key differentiator. Most AI design-to-code tools work best on new projects where they control the entire stack. Tempo Labs can be dropped into an existing React project and will generate components that use the team's existing UI library, follow their naming conventions, and integrate with their state management approach. This makes it practical for production teams, not just prototypers.

As a Y Combinator alumnus, Tempo Labs has focused on engineering maintainability as its core value proposition. The platform is available through paid subscription tiers, targeting frontend development teams who want to accelerate UI development without sacrificing the code quality standards their existing projects demand.

Grok Build

Top Pick

xAI's terminal coding agent with parallel subagents and worktree-aware automation

Grok Build is xAI's terminal-first coding agent for planning, editing, testing, and reviewing code from a local CLI. The early beta exposes subagent controls, worktree mode, headless JSON output, best-of-N parallel attempts, sandbox profiles, and experimental memory. It fits developers comparing Claude Code, Codex, and Gemini CLI for local agentic workflows with deeper parallel execution.

Mitosis

Write components once and compile them into native code for multiple frameworks

Mitosis is Builder.io-backed open-source infrastructure for writing a component once and compiling it into native framework components for React, Vue, Angular, Svelte, Qwik, Solid, React Native, and other targets. It supports cross-framework design systems and Figma-to-code synchronization, but is distinct from the Builder.io visual builder product.

Comparisons

Onlook vs Lovable vs Tempo Labs — Visual React Builders & AI App Development Compared

Visual React development has become a distinct category in 2026, with tools that let designers and developers manipulate real React components through intuitive visual interfaces rather than writing code line by line. This comparison examines three platforms leading this shift: Onlook as an open-source visual editor that connects to your existing codebase, Lovable as a conversational full-stack app builder for rapid product creation, and Tempo Labs as a visual React IDE with multi-agent AI planning and a rich editing canvas.
