Gimbal

Gimbal is built for products that turn prompts or photos into images. It calls models through Replicate and fal with webhooks for long jobs, stores results in Cloudflare R2, and shows a gallery with favorites, upscaling and downloads. Credits are sold as packs through Stripe, with a free trial allowance and an NSFW filter that checks both prompts and outputs.

It is opinionated about async jobs: nothing blocks a request, and the UI polls a job table so slow models never time out. The limitation: per-image costs vary by model and the kit leaves pricing to you. Set credit prices too low and a popular launch can cost more in inference than it earns.
