Deploy and Host genmeta-bot on Railway

genmeta-bot is a Discord bot that reveals AI image generation metadata in uploaded PNGs. It reads both plain PNG text chunks and stealth PNGInfo hidden in pixel LSBs, then replies with an embed showing the prompt, negative prompt, model, sampler, steps, CFG, seed, and size. It supports NovelAI, A1111 (Stable Diffusion WebUI), and Forge.

About Hosting genmeta-bot

genmeta-bot runs as a lightweight Bun worker that connects to the Discord Gateway — no inbound HTTP, domain, or port configuration needed. Hosting takes three steps: create a bot on the Discord Developer Portal and enable the Message Content Intent, set the DISCORD_BOT_TOKEN and DISCORD_APPLICATION_ID variables, and register the slash commands once with bun run deploy-commands --global. Pause state and reply links persist to Turso when TURSO_DATABASE_URL is set, with a local SQLite fallback otherwise. The template ships with a production-ready multi-stage Dockerfile running as a non-root user, and Railway restarts the bot automatically on failure.

Common Use Cases

AI art communities where members share images and want prompts and settings visible without asking the poster
Moderation and provenance checks — verify whether an uploaded image carries generation metadata, including stealth PNGInfo
Recovering your own generation settings (seed, model, sampler) from images you posted earlier

Dependencies for genmeta-bot Hosting

A Discord application and bot token with Message Content Intent enabled
Optional: a Turso database (TURSO_DATABASE_URL) to keep state across redeploys

Deployment Dependencies

Implementation Details

Metadata extraction first parses PNG tEXt / zTXt / iTXt chunks, then falls back to scanning alpha/RGB least-significant bits for stealth_pnginfo / stealth_pngcomp payloads. After the first deploy, register the slash commands once:

bun run deploy-commands --global
