Deploy and Host babel-discord-translator on Railway

babel-discord-translator, also known as Babel, is a self-hosted Discord translation monorepo with two app profiles:

Babel Guild for server/guild installs, public slash-command workflows, server budgets, and server glossaries.
Babel Pocket for user installs, private right-click translations, user-scoped access, and personal usage budgets.

Both apps share the same Railway template, dashboard, SQLite persistence, provider setup, metrics, and operational foundations. Choose which app to deploy by setting BABEL_APP to guild or pocket.

About Hosting babel-discord-translator

Hosting Babel on Railway gives you your own private Discord translation app instance. You provide the Discord token, dashboard password, Railway hosting, and AI provider credentials.

Set BABEL_APP=guild if you want the server-install product for Discord communities. Set BABEL_APP=pocket if you want the user-install product for individuals, trusted friends, or private workflows.

Babel stores configuration, usage, budgets, language preferences, sessions, and app-specific access data in SQLite, so mount a persistent Railway volume at /app/data. After deployment, open the dashboard, complete the setup wizard, configure Vertex AI or an OpenAI-compatible provider, then register the matching Discord commands. Babel does not require privileged Discord intents and keeps translation control in your own deployment.

Common Use Cases

Self-host private translations: Translate Discord messages without paying for a hosted bot subscription.
Server community translation: Use Babel Guild for server installs, /translate, server budgets, and server glossaries.
Personal or trusted-group translation: Use Babel Pocket for user installs and private ephemeral translations.
Usage tracking & customization: Track AI token usage, set budgets, customize prompts, and configure provider settings from the dashboard.

Implementation Details

After the Railway deployment is live, register the Discord commands that match your selected app profile.

For Babel Guild:

DISCORD_APP_ID=your_app_id DISCORD_BOT_TOKEN=your_token npm run register:guild

Babel Guild registers the Babel message context menu plus /translate, /setlang, /mylang, and /help.

For Babel Pocket:

DISCORD_APP_ID=your_app_id DISCORD_BOT_TOKEN=your_token npm run register:pocket

Babel Pocket registers the Babel Pocket message context menu plus /setlang, /mylang, and /help. It does not register the public /translate command.

The dashboard is served from the Railway public domain. Log in with DASHBOARD_PASSWORD, complete the setup wizard, configure your translation provider, and check /livez or /readyz for service health.
