Handoffly, AI Figma Handoff Checker
Project Info
Design handoff breaks down in the same way every time. The developer opens the file, finds something missing, and sends a message. The designer answers, the developer asks again. Days pass.
Handoffly short-circuits that loop. Paste in a Figma URL, select your pages, and within two minutes you have a prioritised list of everything that would cause a developer to stop: missing states, undocumented interactions, accessibility gaps, absent spacing specs. Fix them before handoff. Re-run to check progress.
The Problem
There is no objective definition of what "ready to hand off" means. So designers guess, developers assume, and the gap between design intent and built output grows.
The questions are always the same: What does this button look like when disabled? There is no error state for this form. I cannot find the spacing values. Which breakpoints does this support?
Handoffly creates the standard that was missing. It reads the file the same way a developer would, looking for what's there and, more importantly, what isn't.
How It Works
Connect any Figma file. Choose which pages to include and declare the platform: mobile, desktop, or tablet. The platform context matters: a mobile design should never be flagged for missing desktop breakpoints.
The AI reads the full design tree, every frame, component, variant, instance override, and text label, then applies the same checks a senior designer would run before signing off.
Every gap comes back with a severity (critical, warning, advisory), a plain-language description, a suggested fix written as a direct instruction, and a link directly to the relevant layer in Figma.
Dev Questions
Every gap generates a set of developer questions, the exact questions a developer would ask if they found the issue themselves. The goal is to give designers the full picture of what needs answering before a single message is sent.
Coverage Scores
Alongside the gap report, Handoffly scores your design across five areas: interaction specs, accessibility annotations, responsive breakpoints, component states, and asset specifications.
The readiness score, the single number at the top, is the average across all five. A low score in any area means gaps are blocking, not advisory.
Handoff Package
Once gaps are resolved, Handoffly generates a shareable handoff package. A single link the designer can send to the developer with everything documented, resolved gaps noted, and coverage scores confirmed.
The package exports in whatever format the developer's workflow expects: Markdown for documentation tools, JSON for engineering systems, PDF for stakeholder reviews, or a raw Figma-linked summary for teams staying inside the design tool.
What I Learned
Designing the empty and loading states properly from the start matters more than it looks. They are the first thing a new user sees, and they set the tone for whether the product feels finished or unfinished.
AI severity calibration needs explicit rules, not inference. Early versions were too conservative on critical gaps, which eroded trust in the output. Tightening the prompt and adding post-processing escalation fixed it.
Owning the full stack, design, build, deploy, iterate, gives you a completely different relationship with product decisions. There is no handoff gap when you are both the designer and the developer.
