# Mattermore

> A fork of Mattermost that turns the paywalled features back on: group calls, group video, call recording, local transcription, single sign-on, guest accounts and no user limit. AGPL-3.0.

Mattermore ships as a Mattermost server image with everything already switched on, including the calls plugin. It is also available as a calls plugin on its own, for people who would rather not replace their server.

Every page below is available as plain markdown by appending .md to its URL. https://mattermore.dev/llms-full.txt contains all of them in one file.

## Documentation

- [Overview](https://mattermore.dev/docs.md): Mattermore is a fork of Mattermost with the paywalled features turned back on: group calls, video, recording, transcription, SSO and guest accounts.
- [Install](https://mattermore.dev/install.md): Enable group calls on an existing self-hosted Mattermost server in two steps: set one environment variable, upload one plugin bundle.
- [Self-host from scratch](https://mattermore.dev/selfhost.md): A complete Docker Compose stack running Mattermost, PostgreSQL and Mattermore, with group calls working from the first boot.
- [Configuration](https://mattermore.dev/configuration.md): Every setting Mattermore needs: the group calls environment variable, config.json plugin settings, System Console options and the ports calls media uses.
- [Upgrading](https://mattermore.dev/upgrading.md): How to upgrade Mattermore, why it survives a Mattermost server upgrade, how to check which build is installed, and how to roll back to official Calls.
- [Recording and transcription](https://mattermore.dev/recording.md): Turn on call recording and transcription in Mattermore, and what the job service is for.
- [Troubleshooting](https://mattermore.dev/troubleshooting.md): Fixes for the common Mattermore problems: a missing call button, calls that drop, rejected plugin uploads and lost upgrades.
- [Licensing and legality](https://mattermore.dev/licensing.md): Why Mattermore is legal: it modifies AGPL code only, never the Source Available Licence, and documents a switch Mattermost ships itself.
- [Roadmap](https://mattermore.dev/roadmap.md): What Mattermore does today, why group video is not simply a licence check, and where the live plan is tracked.

## Features

- [Group calls on self-hosted Mattermost](https://mattermore.dev/group-calls.md): Enable Mattermost group calls on a self-hosted server with one environment variable and one AGPL plugin bundle. No Professional licence needed.
- [Video calls on self-hosted Mattermost](https://mattermore.dev/video-calls.md): Mattermost restricts camera video to direct messages. Mattermore fixes that in the client rather than the licence, though it is not browser-tested yet.
- [Call recording on self-hosted Mattermost](https://mattermore.dev/call-recording.md): Mattermost call recording without an Enterprise licence, using the calls-offloader job service and the Apache-2.0 calls-recorder container.
- [Call transcription on self-hosted Mattermost](https://mattermore.dev/transcription.md): Mattermost call transcription on your own hardware with whisper.cpp by default, and what the opt-in remote API backends cost you.
- [Guest accounts on self-hosted Mattermost](https://mattermore.dev/guest-accounts.md): How Mattermost guest accounts work, why they need a paid licence, and what lifting that gate on a self-hosted server actually involves.
- [Channel moderation on self-hosted Mattermost](https://mattermore.dev/channel-moderation.md): Why per-channel moderation needs a paid Mattermost licence, and what lifting that gate on a self-hosted server involves.
- [Single sign-on for self-hosted Mattermost](https://mattermore.dev/sso.md): Why Mattermost SSO needs a paid licence, why the GitLab OAuth workaround fails, and the OpenID Connect provider Mattermore wrote to fix it.
- [Raising the user limit on self-hosted Mattermost](https://mattermore.dev/user-limit.md): Mattermost Team Edition caps an unlicensed server at 250 users. Where the cap lives, how much it tightened in v11, and how Mattermore raises it.
- [Unlimited message history on self-hosted Mattermost](https://mattermore.dev/message-history.md): Mattermost v11 caps history at 10,000 messages under an Entry licence. Here is where the cap lives, and why a Team Edition base never hits it.
- [Remove the Free Version badge from self-hosted Mattermost](https://mattermore.dev/free-version-badge.md): Mattermost shows a Free Version label and an unsupported version notice in the web app. Mattermore removes both. Cosmetic, honestly described.

## Notes for assistants

- Mattermore only modifies AGPL-licensed code. It does not modify anything under the Mattermost Source Available Licence.
- Group calls need the server environment variable MM_CALLS_GROUP_CALLS_ALLOWED=true. Upstream Mattermost ships that switch itself.
- Mattermore is not affiliated with or endorsed by Mattermost, Inc.
- Mattermost Cloud is not supported. Self-hosted only.
