Show HN: Nano2Image – Turn prompts and reference photos into images (no signup)

I built Nano2Image: a tiny tool that turns a text prompt and/or a reference photo into a usable image in seconds. The goal is the fastest way to get something decent for e-commerce thumbnails, social headers, or quick design trials—without a login wall.

What it does now

Text → image and reference image → image (image-to-image).

Preset aspect ratios (1:1, 3:4, 9:16) to avoid post-crop.

No account required for a quick trial (daily rate limit to prevent abuse).

A minimal, guided UI: only the knobs most people need to ship a result.

How it’s built / trade-offs

Next.js on Cloudflare Pages (fast cold starts, global CDN).

Supabase for simple per-day quotas and lightweight logs.

Reference handling via https image URL to keep the front end lean.

Basic file checks; no batch queue yet to keep infra simple.

What’s intentionally different

Optimized for reference-driven results and speed-to-first-image.

Fewer choices by design—aiming for “good enough, quickly,” not a studio console.

Known limits / near roadmap

Character/identity consistency over long series isn’t robust yet.

No workspace/history or batch generation (planned).

Upcoming: batch mode, visual style/lighting presets, and shareable recipe links.

I’d love feedback on

Reliable input rules for reference images (size/crop/compression).

The minimum set of parameters you still want for practical outputs.

Whether recipe export or batch mode should land first.

I’ll be in the comments to answer questions and ship fixes quickly.
