Deploy and Host croma.aurora33.live on Railway

croma.aurora33.live is a free, no-sign-up bulk image compressor. It compresses, resizes, and converts images to WebP, JPEG, PNG, or AVIF — entirely server-side, with no account and no database. Uploaded files are processed temporarily and deleted automatically after about an hour. Built with Next.js by Aurora33.

About Hosting croma.aurora33.live

Hosting croma.aurora33.live means running a single Next.js (App Router) web service powered by Sharp/libvips for native image processing. There is no database and no persistent storage to manage: jobs live in memory and uploaded files sit in an ephemeral temp directory that a built-in cron cleans on a schedule. Railway auto-detects the Next.js app via Railpack, runs the production build, and serves it with a health check at /api/health. The app ships with built-in resilience — a bounded job queue, per-IP rate limiting, and a same-origin guard — so a small instance degrades gracefully under load instead of crashing. Configuration is entirely through environment variables, with no extra services required.

Common Use Cases

Spin up your own private image compressor with higher upload limits than the shared hosted version
Give a team or community a free, no-login tool to optimize images for the web (WebP/AVIF)
Batch-convert and resize images for a site, store, or content pipeline without third-party SaaS
