How it works

A clearer handoff, step by step

A local review of delivery requirements, followed by your own runtime testing.

Gather the delivery

Use the Spine 4.2 JSON export, text atlas and PNG pages, plus your required names and file budgets.

Check the contract

Run static checks for required names, file and atlas references, export version, PNG integrity and budgets.

Review the report

Read the HTML report and JSON receipt with SHA-256 hashes. Compare revisions to see what changed.

Test in your project

Resolve flagged items, then test rendering and behavior in your target runtime. Static checks do not prove runtime compatibility.

Check your handoff

Animation Handoff Bench

A local, offline handoff contract checker for Spine 4.2 JSON, text atlas and PNG pages. Alpha release available as a browser HTML tool and Node CLI. $9 one-time purchase.

Required names

Check exact animation, skin, event definition, bone, slot and point attachment names against your handoff requirements.

Files and references

Check export version, file and atlas references, PNG structure and CRC, and the budgets you define.

Readable evidence

Review an HTML report and a JSON receipt with SHA-256 hashes, so the checked delivery is clearly identified.

Revision comparison

Compare receipts to inspect changes between deliveries. Keep runtime, animation and visual testing as a separate step.

It means the supplied files passed the configured static checks. It is not a rendering test or a guarantee of runtime compatibility. Animation timelines, meshes, geometry and behavior still need review in your target runtime.
An HTML report and a JSON receipt with SHA-256 hashes. A revision comparison helps inspect changes between deliveries. The tool checks required exact names, file and atlas references, export version, PNG structure and CRC, and configured budgets.
Independent developers, animators and small teams who need to check delivery requirements and review file changes before integration.
