Design Handoff
AI-powered design-to-dev handoff
Your AI agent generates detailed specs from your mockups, creates implementation tickets with acceptance criteria, and helps you review the developer's work against your design.
Works with your existing Claude Code and Codex subscription or API key
The Problem
Handoff loses context and intent
The gap between what a designer envisions and what a developer builds is where quality dies. Traditional handoff tools don't bridge this gap.
- Design specs are written manually and miss important details
- Developers interpret mockups differently than intended
- Acceptance criteria are vague or missing entirely
- Reviewing implementation against the original design requires switching between tools
How It Works
From design to implementation with full context
Generate specs
Your agent reads your mockup and produces detailed specs -- spacing, colors, typography, interaction behavior, responsive breakpoints, and accessibility notes.
Create tickets
Your agent converts design specs into implementation tickets with screenshots, acceptance criteria, and component references -- ready for engineering.
Review implementation
Compare the developer's code against your mockup. Your agent highlights discrepancies and suggests corrections.
The Difference
Handoff that preserves design intent
Without Nimbalyst
- ✕ Write specs manually, missing spacing and interaction details
- ✕ Developers ask follow-up questions for weeks
- ✕ Implementation drifts from the original design
- ✕ Review requires opening mockup and code side by side in different tools
With Nimbalyst
- ✓ Agent extracts complete specs from your mockup automatically
- ✓ Tickets include everything a developer needs to implement
- ✓ Agent compares implementation against the original design
- ✓ Mockup, specs, tickets, and code review in one workspace
