Figma Plugin vs Widget: What Is the Difference

A plugin runs, does something, and closes. A widget stays on the canvas, rendered as a live object other people can see and interact with. That one distinction — temporary tool versus persistent canvas citizen — explains almost every other difference between the two, and it’s worth holding onto before diving into the specifics below.

Both are built with the same core technologies. Both live in a manifest.json, both ship through the Figma community, and both can call a large overlapping slice of the plugin API. That overlap is exactly why the confusion persists — the tools look similar enough on paper that the practical differences get glossed over until someone builds the wrong one for the job.

Below are the five distinctions that matter most, ranked from the one that causes the most real-world confusion down to the one that’s more of a technical footnote.

1. Lifecycle: Does It Run Once, or Does It Live on the Canvas?

This is the difference that trips up the most people, because it’s conceptual rather than syntactic — nothing in the code forces you to think about it upfront.

A plugin is invoked, executes its task, and terminates. Even a plugin with a persistent UI panel is fundamentally a session: open it, use it, close it, and any state it held disappears unless you’ve explicitly saved it somewhere. Think of a plugin as a tool you pick up off a shelf.

A widget is an object. Once placed on a frame, it stays there — through file reloads, through other people opening the file, through version history rollbacks. It renders its own UI directly on the canvas using the figma.widget API, and that UI persists as part of the document, not as a temporary session layered on top of it.

Why this ranks first: every other difference on this list is downstream of this one. Get this distinction right, and the rest of the API differences make intuitive sense. Get it wrong, and you’ll end up building a widget that behaves like it wants to be a plugin, or vice versa — a common enough mistake that Figma’s own documentation calls it out directly.

2. Collaboration: Solo Tool vs. Shared Canvas Object

Plugins are inherently single-user in the moment of execution. If two people on the same file both run a plugin, they’re running two independent sessions — neither sees the other’s plugin state unless the plugin itself was built to write shared data.

Widgets are collaborative by default. A widget placed on a canvas is visible to everyone with access to that file, and multiple people can interact with the same widget instance simultaneously — clicking its buttons, updating its state — the same way they’d interact with any other shared object in a multiplayer Figma file. This is why sticky-note widgets, voting widgets, and status-tracker widgets exist as a category: they’re solving problems that only make sense when multiple people are touching the same object over time.

Practical implication: if the feature you’re building needs to be seen and used by teammates without each person re-triggering it individually, that’s a strong signal you’re looking at a widget, not a plugin.

3. Storage: Session Memory vs. Document-Embedded State

Plugins can store data — clientStorage for local persistence, plugin data attached to nodes for file-specific storage — but that data lives alongside the design, accessed only when the plugin is deliberately reopened.

Widgets carry their state as part of the widget node itself, using useSyncedState and related hooks from the widget API. That state travels with the file. Duplicate the frame, and the widget’s state duplicates with it. Open the file offline later, and the widget still displays its last known state without anyone needing to run anything.

This distinction matters more than it first appears, because it determines whether your feature’s data survives the ordinary things people do to files — copying, branching, archiving — without extra plumbing on your part.

4. UI Rendering: Iframe Panel vs. Canvas-Native Rendering

A plugin’s UI, when it has one, renders in an iframe — a floating panel with standard HTML, CSS, and JavaScript, communicating with the plugin’s sandboxed main code through message passing. It looks and behaves like a small web app sitting on top of the canvas.

A widget’s UI is built with JSX-like syntax from the widget API and renders as an actual node structure on the canvas itself — auto layout frames, text nodes, and shapes assembled through code, but appearing to Figma (and to other users) as native canvas objects, resizable and positioned like anything else on the page.

This is a meaningful constraint in practice. Widget UI has to be built with the primitives the widget API exposes, not arbitrary HTML — no dropping in a custom CSS animation library. Plugins have no such restriction inside their iframe, at the cost of that UI never truly becoming part of the design itself.

5. Distribution and Discovery: Where Users Find Them

This one is a smaller practical difference, but worth knowing before you plan a release. Plugins and widgets are published through separate sections of the Figma community — a plugin listed under Plugins won’t surface in widget search, and the reverse is equally true. The submission and review process is similar for both, but the manifest declares which type you’re building, and that declaration determines the entire distribution path.

For teams building internal tools, this distinction matters less — private plugins and private widgets are both accessible within an organization regardless of public listing. But for anything meant for the broader Figma community, knowing which category your idea falls into before you start building saves a rebuild later, since converting a plugin into a widget isn’t a matter of flipping a flag — it’s closer to rebuilding the interaction model from the ground up.

Side-by-Side Summary

Which One Should You Actually Build?

If the feature is something a single person invokes to accomplish a task — renaming layers in bulk, generating placeholder content, exporting assets — that’s plugin territory, full stop. The moment execution finishes, there’s nothing left for the feature to do.

If the feature needs to exist as a visible, ongoing presence that a team interacts with over time — a shared checklist, a live poll, a status indicator that updates as work progresses — that points toward a widget instead. The test that tends to resolve ambiguous cases quickly: would this feature still make sense if it never closed? If yes, build a widget. If the whole point is a discrete task with a clear beginning and end, build a plugin.
