Replies within 72 hours, and updates through the current major version. The panel can write a redacted support bundle for you, with system info and job history but no images, no credentials, and personal paths stripped, so diagnosing a problem does not mean sending me your files.

Yes. Every image is saved with a JSON sidecar recording the capsule and version, a hash of the workflow, every input value, and the seed actually used. History keeps that across Blender restarts, with Reuse, Variation, Retry, and Promote. Same seed and same settings reproduce a result; a different camera or frame will drift.

Yes, by wrapping a workflow in a capsule: the API-format workflow export plus a small manifest describing which inputs to expose and which render passes to feed it. Drop the folder into the user capsule directory and it appears in the panel with its inputs laid out automatically. This is documented, and for a workflow you already have it takes minutes. Arbitrary workflows do not appear automatically without that manifest.

Windows is the tested and supported platform. The add-on is pure Python with no compiled parts and no Windows-only APIs, so macOS and Linux are expected to work, but they are not in the release matrix and are not advertised as supported. Please do not buy on that assumption. If you are on one of those platforms and hit a problem, open a support ticket and I will help.

No. Nothing runs in the cloud, so there is nothing to meter. You supply the hardware and the models, and the purchase is one-time. If you choose to point Reshoot at a paid remote ComfyUI, that provider's costs are between you and them; Reshoot neither meters nor marks up anything.

ComfyUI is not included and is not installed for you. You need your own local ComfyUI (Desktop or portable, both verified), at least one SDXL-family checkpoint, and a GPU that can already run SDXL at a speed you find acceptable. Product Studio Pro also needs an SDXL depth ControlNet, about 2.5 GB, and the documented one is Apache-2.0. None of these are bundled.
