Deploy and Host Modbot on Railway

Modbot is self-hosted moderation for VRChat groups. It keeps ban case files and a searchable audit log, watches live instances as they fill, syncs bans and roles with Discord, and feeds a companion app that puts your group's roster and moderation actions in front of you without leaving VRChat.

About Hosting Modbot

Modbot runs as one container plus one PostgreSQL database. The image carries the API, the web app, the Discord bot and the sync scheduler together, so there is nothing else to wire up. DATABASE_URL is the only variable you must set; almost everything else is configured in the web app and stored in the database. Point the health check at /health/ready, generate a public domain, and opening it lands you in a setup wizard that connects your VRChat account and group. Keep the service at one replica: Modbot holds a single VRChat session and paces its own requests against one rate limit, so a second copy would double them.

Common Use Cases

Run a group's moderation off one record. Ban case files with evidence, notes on a person, and an audit log of who did what and when, instead of a Discord thread nobody can search a year later.
See an instance while it is happening. Watch who is in a public instance as it fills, get told when someone you have flagged arrives, and kick or ban them from the overlay without taking the headset off.
Keep Discord and VRChat in step. Sync bans and roles between the two, so somebody removed in one place does not walk back in through the other.

Dependencies for Modbot Hosting

PostgreSQL. Required. Modbot refuses to start without DATABASE_URL.
A VRChat account with moderator rights in the group. Connected in the setup wizard, not an environment variable.
A Discord bot token. Optional, and only for the Discord features.
An S3-compatible bucket. Optional, for storing evidence files.
