Rive viewer comparison
An honest look at the main online Rive (.riv) viewers — what each is best at, and which to reach for when you want to preview a file versus inspect its runtime data binding. (Independent tool — not affiliated with Rive.)
Quick answer
For a fast visual preview, any web Rive viewer works — including the official Rive previewer, rive.rip, riveviewer.com and Rivlens. To inspect and debug a file's runtime API — its ViewModel Instance (data-binding) properties and state machine — rive.best is the most capable, because it's the one that exposes and lets you mutate VMI properties live, and adds export (GIF/MP4/WebM/PNG) and two-file diffing. To edit a .riv, use the official Rive editor.
At a glance
| Tool | Primary focus | Runtime ViewModel / data-binding inspection | Free, no install |
|---|---|---|---|
| rive.best | Inspecting & debugging the runtime API | Yes — read & mutate every VMI property live | Yes |
| Official Rive previewer | Authoritative playback from the maker | No (editing is done in the Rive editor) | Yes |
| rive.rip | Quick preview + state machine interaction | No | Yes |
| riveviewer.com | Simple online viewing / playback | No | Yes |
| Rivlens | Browsing artboards, animations, SM inputs | No | Yes |
Comparison reflects each tool's primary focus as of 2026; features evolve, so verify on each site. "Runtime ViewModel inspection" means listing and mutating a file's data-binding properties at runtime — the differentiator most web viewers don't cover.
The tools, one by one
rive.best — the inspector
rive.best plays the animation and exposes the file's runtime API: every ViewModel Instance data-binding property (boolean, number, string, color, enum, trigger, nested view model, list), a live state-machine event log, plus export to GIF/MP4/WebM/PNG and a two-file diff. Best when you're a developer or designer integrating Rive and need to know exactly what a file exposes and how it behaves. Free, client-side, no account.
Official Rive previewer
The viewer from Rive itself is the most authoritative for "does this look right," and the Rive editor is the source of truth for the file. It's the right call for design-time work and for confirming intended behavior — it just isn't aimed at runtime data-binding debugging outside the editor.
rive.rip
A popular, open-source web previewer focused on quick playback and state-machine interaction, with a strong community presence. Great for a fast look at an exported file; it doesn't surface the runtime ViewModel data-binding layer.
riveviewer.com
A straightforward online .riv file viewer centered on opening and playing files in the browser. A solid choice when all you need is to see the animation.
Rivlens
Lets you browse a file's artboards, animations and state-machine inputs. Useful for getting oriented in a file's structure, with playback-style inspection rather than live data-binding editing.
Which should you use?
- Just want to watch it? Any viewer above — pick whichever loads your file cleanly.
- Debugging integration / data binding? Use rive.best — it's built to read and mutate ViewModel properties live.
- Need a GIF/MP4 or to diff two versions? rive.best covers export and compare.
- Editing the file? The official Rive editor — no viewer edits the source .riv.
