⚠ Preliminary, based on public research, hands-on test pending. These scores come from a desk review of public sources (official pricing pages, docs, changelogs), linked on each tool page. Rex hasn't run the hands-on tests yet, so tiers shown are projected. Under our rubric, a tool's official tier is capped at B until it's tested.

Quick take (preliminary): both are specialist pixel-art tools and tie on our desk-review score. PixelLab is a subscription (from $12/mo) with a web app, Aseprite integration and API. Retro Diffusion sells a one-time $65 Aseprite extension that runs locally, plus a pay-per-image hosted API.
- Pick PixelLab if you want a hosted workflow, animation tools and predictable monthly generations.
- Pick Retro Diffusion if you own a decent GPU, live in Aseprite and hate subscriptions.
Side-by-side sprite outputs are queued for week 2.
