Studio composer with live reveal
Prompt, negative prompt, FLUX schnell/dev/pro, size preset and a 1-4 image count, all on one /studio screen. The generating card polls every second and reveals each image the moment fal finishes — no refresh.
AI image studio starter
Launch an AI image studio.
A complete fal.ai image generator — a gorgeous studio and gallery that open free in the sidebar app, then meter each render by credit balance.
Prompt in, owned pixels out
Type a line. Watch it develop.
A credit-metered FLUX pipeline with a live render reveal — the prompt types itself, the canvas resolves out of noise, and one credit clicks off the meter. Every result is re-fetched into storage you own.
PROMPT TO PIXEL
A fal.ai image studio, already wired
Type a prompt, pick a FLUX model and size, spend a credit per image. Every render lands in your own private R2 bucket behind a gallery you own — keys, billing and credit metering all included.
Gallery with folders and lightbox
A /gallery masonry grid with likes, folders you create and rename, and a lightbox that does prev/next, copy-prompt and download. Filter by liked or collection; move images between folders.
Free to open, gated by credits
/studio and /gallery live in the member sidebar app and open for any signed-in user — no hard paywall. Each generation spends 1 credit up front; hit zero and you're routed to top-up. If fal fails or the submit throws, the credits are refunded automatically.
Remix any result
Hit Remix on a gallery image and its prompt, model, seed and size load straight back into the studio. Lock the seed or randomise it.
Your own R2 bucket
Every image is downloaded from fal and uploaded into your private Cloudflare R2 bucket. No SDK — a plain cURL S3 Sig V4 signer in bootstrap.php.
Off until you add a FAL_KEY
The whole pipeline is dormant until FAL_KEY and your R2 keys are set, so the rest of the stack runs clean without it. A built-in dev mock paints gradient PNGs so you can click through the full studio and gallery before you spend a penny on fal.
Render, reconcile, own
Watch a batch land in storage you own
Type a prompt, pick a FLUX model, spend a credit per image — and every result is re-fetched server-side and self-hosted in your private R2 before it hits the grid.

Questions
The honest FAQ.
Whatever you decide — a generation, an API call, an export, a render minute. Plans grant credits; each action spends them through one ledger via consume_credits_for_action().
Your call per plan. Period credits top up to a fresh allowance each period by default, and you can switch to rollover in the plan config.
Yes — combine recurring plans that grant credits with one-time purchases for top-up packs.
The starter includes prepared queries, signed Stripe webhooks, CSRF checks, rate limiting, session hardening, setup diagnostics and regression tests. Configure the enabled providers, verify backups and test your own product before launch.
You pay your hosting and service providers directly. Budget for a PHP server, domain, transactional email and payment processing. Image generation/storage and native app store accounts add costs if you enable them. Check provider pricing for your region and expected usage; the template itself is a one-time purchase.
