Instance Monitor
A live view of your current instance — see joins, leaves, and session history as they happen instead of digging through log files.
Overview
VRCS by Nyxall is an advanced VRChat companion, built on an open-source foundation and extended with an instance monitor, group moderation tooling, a full logs dashboard, and a managed auto-update pipeline.
VRCS is a heavily customized build of an open-source VRChat companion app. It keeps everything the upstream project does well — friend activity tracking, world and avatar management, notifications, the VR overlay — and layers on tooling for people who moderate groups, run events, or manage multiple accounts.
Built for moderation work
The fork exists because group moderation in VRChat involves real operational work: knowing who is in your instance, tracking invitations at group scale, and keeping an auditable local record of what happened. The Instance Monitor, Group Scanner, and Logs Dashboard turn that from log-file archaeology into something you can actually see.
Access
VRCS is members-only. Create a free Nyxall account, request access, and once the studio approves it you can download the installer and sign in to the app with that same account — no access key. Approval keeps the backend features (sync, policies, group tooling) limited to a known community. The Getting Started guide walks through each step.
Updates you don’t have to think about
VRCS ships from a single, verified release pipeline. The app checks for updates automatically, downloads over HTTPS, verifies the file hash before installing, and never updates to anything that hasn’t passed the release checks. Release history and checksums for every build are published on the releases page.
Coming to Discord
VRCS Discord is a companion in development. It will let a group’s approved staff check moderation activity from their Discord server, using the record VRCS keeps. It isn’t available yet.
What it does
7 features. The interfaces below are illustrative studies of each one.
-
Instance Monitor
A live view of your current instance — see joins, leaves, and session history as they happen instead of digging through log files.
-
Group moderation suite
Group Invitation Manager, Group Scanner, and group-level moderation tools built for people who actually run VRChat communities.
-
Logs Dashboard
Seventeen categories of searchable, locally stored logs backed by SQLite. Your history stays on your machine and stays queryable.
-
Blacklist Avatar Alert
Get alerted when avatars you have flagged show up around you, so moderation decisions travel with you between sessions.
-
Managed updates
The app checks for new releases automatically, verifies the download against its published checksum, and installs in place — no manual downloads.
-
Account & content workflows
Bulk account importer, friend inviter, avatar cache manager, and content transfer for power users managing more than one identity.
-
Everything the original does
The full open-source feature set underneath: friend activity tracking, world and avatar browsing, notifications, and the VR overlay on Windows.
