Where this came from
Not a new idea.
A repaired one.
The original is AEUX, built by the motion design team at Google and released as open source. For years it was the way designers got work out of Sketch and Figma and into After Effects.
Then it stopped. The last release, 0.8.2, went out in September 2022. Figma changed, After Effects changed, and the transfer quietly broke. People kept opening issues about it and nobody picked them up.
Because it was open source, it did not have to end there. We repaired it. The connection works again, the panel was rebuilt, the host script runs on every After Effects from 2019 through 2026, and the local server no longer holds a port it has finished with.
We keep this alive, and we fix it based on what you report. If it breaks against a new version of Figma or After Effects, tell us and it gets looked at. That is the whole arrangement, and it is why this is free.
All the original work, and the credit for it, belongs to the AEUX authors. This is their code, repaired and maintained, offered to the same community it was written for. Not affiliated with or endorsed by Google or Adobe.
