The best design handoff tools today are either built into the design app itself, as a developer view or inspect panel, or sit on top as a separate delivery layer that works with any design tool. If your whole team designs in one tool, use its built-in handoff; if designers use several tools or clients send files, a delivery layer is cleaner.
Two of the names people still search for are gone. Avocode's website now carries a farewell notice, and the old InVision address lands on Miro, so InVision's inspect tool is no longer something you can sign up to on its own. If your team's handoff process was built around either, this is the list of what's left and how to choose between it.
What changed, and why it matters
Handoff used to be its own category: a designer exported screens to a separate app, and developers opened that app to measure spacing, copy colours and download icons. Much of that job has moved inside the design tools themselves. The main design apps now ship a developer view or inspect panel, and in some cases a cheaper seat built for people who read files rather than edit them.
That leaves the stand-alone tools with a narrower but real job: publishing finished, approved screens from any design tool into one place developers trust, with versions, styleguides and assets kept apart from the messy working file. The third strand is newer. Code tools now turn designs straight into front-end code, and design-system tools give both people and AI coding agents one source of components to build from.
So the question isn't "which handoff app" any more. It's whether handoff should live in the design file, next to it, or in code.
Handoff inside the design tool
Figma Dev Mode
The developer view inside Figma, turning design files into inspectable specs and code, sold as a separate seat for people who build rather than design.
Sketch
A Mac-first design app whose web app lets developers and other viewers browse, comment on and inspect documents, with handoff included.
Penpot
Teams that want open source and the option to self-host use this design platform, whose inspect panel speaks CSS, HTML, SVG and JSON.
Pixso
Collaborative UI design tool with a handoff section and a developer view built into its plans.
Marvel
Design and prototyping platform that generates design specs automatically through its developer handoff feature.
UXPin
Built around prototyping and design systems, with a handoff option so developers work from the same components the designers used.
Delivery layers and code tools that sit on top
Zeplin
A separate delivery layer: designers publish finished screens from their design tool, and developers get specs, assets and styleguides in one place.
Mockplus Cloud
Collaboration and handoff product from Mockplus, pitched by its maker as an alternative to InVision for sharing and inspecting designs.
Anima
For developers who'd rather start from code than specs: it turns Figma designs into front-end code and includes an AI builder.
Handoff.com
A design-system tool that gives people and AI agents access to the same components, so whatever gets built follows one shared standard.
What a developer should be able to pull from any handoff
Whichever type you pick, the test is simple: can a developer build the screen without messaging the designer? That means the tool must give them, without guesswork:
- Exact spacing, sizes and positions, in the units the codebase uses, not just pixels on an artboard.
- Colours and type as named tokens or styles, not loose hex values. If the button blue is called primary-500 in code, it should be called that in the handoff.
- Every asset exportable at the right scale and format, with icons as SVG.
- All the states: hover, focus, disabled, error, empty, loading. Missing states are a common reason a build looks finished and isn't.
- A clear mark on which screens are approved and which version is current. Developers building from a draft frame waste more time than any missing measurement.
- Comments that stay attached to the element they're about, so questions don't vanish into chat.
Code output is a bonus, not the point. Generated CSS for one element is handy for checking a value; generated components for a whole screen need a developer's review before they go anywhere near production.

Choosing by team shape, and who pays for which seat
Count heads before you compare plans: designers who edit, developers who inspect, and people like product managers and clients who only look. The seat-priced tools on this list charge from about $7 to $16 per person a month, and how they treat the people who only inspect decides more of the bill than any feature.
Everyone designs in one tool, small team. Use that tool's own developer view or inspect panel; a separate layer is one more place for versions to drift. Some design tools sell developers a cheaper seat than designers, with inspect and code access but no editing, which is fine for a handful of engineers and adds up when every engineer needs one.
Many developers, few designers. Look for the model where anyone with view access inspects and comments for nothing and only editors pay. That one line on the pricing page can decide it.
Agency with clients sending files from different tools. A delivery layer that takes designs from any source and gives developers one consistent view. At least one lets you pay per project with unlimited designers and developers instead of per seat, so price both ways if your teams rotate across short jobs.
Team that needs control of its own data. The open-source route charges per editor on its cloud plan with a monthly ceiling, and nothing for the software if you host it yourself.
Front-end developers who want to skip measuring altogether. A design-to-code tool, with the output treated as a first draft. Our round-up of Figma to code plugins compares that approach in more depth.

Last step: an hour with a real screen
Pick one screen your team built recently, ideally one with a form, a few states and some icons. Put it into the two tools on your shortlist, then hand each to a developer who hasn't seen the design and ask them to list every value they'd need to rebuild it. Time how long it takes and note every point where they had to guess or ask.
Then flip it. Ask the designer to change one colour token and one spacing value, and see how quickly that change shows up on the developer's side, and whether it's flagged as a change. A handoff that goes stale quietly is worse than none, because people trust it.
The tool with fewer guesses and faster, visible updates wins, whatever the feature list says. If your shortlist is really about which design tool to use at all, start with our guide to Figma alternatives and come back once that's settled.

Frequently asked questions
Should developers get edit access to the design file?
Usually not. View or inspect access is enough to build from, and it keeps accidental moves and deleted layers out of the approved design. Give edit access to the one or two developers who maintain the design system, if anyone.
Do we still need a handoff meeting if the tool does the specs?
Yes, a short one. Specs answer "what size" and "what colour". A ten-minute walk-through answers "why": what happens on a slow connection, which parts are likely to change, what the designer is unsure of. That's the part no tool captures.
What should we keep in case a handoff tool shuts down?
Keep the source design files in your design tool, not only in the handoff layer, and export approved assets and token values into your code repository as you go. If the tool closes, you lose a convenient view rather than the record of what was agreed.
