✨

A Rive file viewer with state machine testing

  • Keeps the uploaded `.riv` file in your browser with no ToolBuddy server upload.
  • Runs Rive rendering inside an isolated worker with OffscreenCanvas so ToolBuddy can recover if runtime startup fails.
  • Exposes artboards, animations, state machines, inputs, and playback speed in one review workspace.
  • Adds a state timeline and event recorder so runtime behavior is easier to explain during QA and handoff.
  • Includes layout, scale, background, and inspector overlays for embed testing.
  • Lets reviewers export a local JSON session summary without sharing source files.
🎯

Review Rive animations before you ship them

  • Test interactive Rive components before adding runtime code.
  • Verify artboards, animations, and state machines exported from Rive.
  • Review state transitions and input changes during designer-to-developer handoff.
  • Check layout behavior for web, app, game, or no-code embeds.
  • Export a local JSON review session for debugging or QA follow-up.

About Rive Animation Viewer

Rive Viewer OnlineRive PreviewRIV File Viewer

Open and preview .riv files online

Rive Animation Viewer opens exported `.riv` runtime files directly in your browser so designers, developers, and QA reviewers can inspect the exact runtime asset that will ship.

The tool validates the `RIVE` binary signature before passing a copy of the file buffer to an isolated worker preview, which keeps the main page responsive even if a runtime load fails.

Rive preview for artboards, animations and state machines

Switch between exported artboards, choose animation clips, and run state machines from one local review workspace instead of bouncing between multiple test surfaces.

The preview keeps selection context visible on-canvas while the inspector overlay summarizes signature, counts, and artboard sizing for quick sanity checks.

Test interactive inputs and review behavior

When a state machine exposes inputs, you can toggle booleans, edit numbers, and fire triggers in the live runtime without writing integration code first.

State timeline and event recorder panels make those interactions easier to explain during QA, review, and engineer handoff because selections, runtime events, and state changes stay visible.

Check layout, speed, and background behavior

Fit, alignment, scale, speed, and background controls help validate how the animation will sit and feel inside real product surfaces.

Responsive canvas resizing keeps the preview useful across desktop and mobile checks while handoff mode strips the panel down to the review surfaces that matter most.

Keep the preview local and share structured review notes

Uploaded `.riv` files are read locally and are not uploaded to ToolBuddy servers. The event recorder can export a local JSON review snapshot without copying your source animation to a backend.

The isolated worker loads the Rive canvas runtime and WASM from the Rive CDN; if a `.riv` references Rive-hosted assets, the runtime may fetch those assets to complete the preview.
