Draupnir

A highly capable Matrix moderation bot and protection platform, trusted by room moderators and homeserver admins alike.

Visit #draupnir:matrix.org in your client and come say hi.

Please see the draupnir documentation for installation instructions and usage guides.

Features

• Draupnir's UX is centred around prompting you with questions to carry out specific moderation tasks by shadowing the actions taken by your Matrix Client.

• Draupnir synchonises bans for users, and servers across all of the matrix rooms that you moderate

• Draupnir can protect your community by applying policies from community curated policy lists. For example lists such as the the community moderation effort, can be watched to protect your rooms around the clock. This means that adjacent Matrix communities can warn and protect each other of known threats. Draupnir and the list provided by the community moderation effort are the bread and butter essentials of moderating public spaces on Matrix.

• Draupnir includes a series of protections that can be enabled that can help you in given scenarios when your community is being targeted.

• Draupnir includes homeserver administrative features, such as reviewing abuse reports, deactivating user accounts and shutting down rooms. This also includes protecting your homeserver with Draupnir's watched policy rooms.

• Draupnir is primarily a room moderation bot and can be used with or without server administrative capabilities.

• Draupnir is a forwards and backwards compatible drop in replacement for Mjolnir.

Prompt UX

The main difference from Mjolnir is that it is no longer necessary to use commands for some functions. Banning a user in a protected room from your Matrix client will cause Draupnir to show a prompt in the management room, which will offer to add the ban to a policy list¹.

You can also unban users the same way, and Draupnir will prompt you to unban them without any confusing hiccups. If you do still wish to use the ban command, please note that users and other entities that are being banned are now the first argument to the ban command. It is now also possible to provide only the entity to Draupnir and have Draupnir prompt you for the policy list and the ban reason.

In general, all commands have been migrated to a new interface which feature better error messages for common problems and allow admins to trace the cause of unexpected errors much more easily.

Technical differences from Mjolnir and other moderation bots

I offer you the ring, which was burned, laid upon the pyre of Baldr by Odin.

Draupnir started as a fork of Mjolnir, in order to radically refactor the code base and break a feature freeze. Draupnir has now completed this refactor and large sections of the the code base are now very distinct, as much of Draupnir was rewritten.

Draupnir remains a forwards and backwards compatible drop in replacement for Mjolnir.

• Draupnir is much less dependant on commands and will automatically send prompts to the management room. Prompts are sent for inviting Draupnir to protect rooms, watch policy lists, ban users, and unban users.

• Draupnir is much more responsive. Unlike Mjolnir and other bots, Draupnir does not need to request any data from the homeserver before applying new bans or to ban new users.

• Draupnir uses an advanced persistent revision system for room state, members, policies, and policy matches. By using revisions, Draupnir only has to process room state once in terms of simple deltas as room state is updated.

• Draupnir offers a room state backing store, allowing Draupnir to startup quickly, even when deployed at distance from the homeserver.

• Draupnir's core functionality is implemented as protections, which can be configured and dynamically turned on and off. If you can write even a little JS/TS, Draupnir's behaviour can be radically changed or customized. And because the core functionality is implemented with the extension system, there are less limits.

• A huge effort has been spent refactoring the code base, paving the way for future feature development of Draupnir and adjacent projects. This includes the rewrite of the core of Draupnir into the matrix-protection-suite, providing all the Matrix client code required to operate a protection platform. The matrix-protection-suite also covers severall shortfalls in the available SDK's, providing event parsing and types that keep code secure and sound. The interface-manager providing an advanced command-oriented interface (note, this does not mean command-line interface). The matrix-basic-types library for dealing with Matrix's various string types. And finally the introduction of prettier, eslint and typescript-eslint into Draupnir's development tooling, modernising TypeScript development.

Status

Draupnir is being supported with a grant from NLnet, the goals of the work are described here

Currently The UX and code base of Draupnir has been overhauled and we have recently passed a huge milestone: Draupnir's 2.0.0 release.

Migration

Migrating from Mjolnir is straightforward and requires no manual steps, migration for your setup is likely as simple as changing your server config to pull the latest Draupnir docker image instead of a mjolnir one. Draupnir remains backwards compatible so that it is possible to try Draupnir and still have the option to switch back to Mjolnir.

Any problems with migration should be reported to our support room.

Setting up

See the setup documentation for first-time setup documentation.

See the configuration sample with documentation for detailed information about Draupnir's configuration.

See homeserver administration for how to use Draupnir's features to protect your homeserver and users.

Quickstart guide

After your bot is up and running, you'll want to run a couple commands to get everything set up:

1. !draupnir list create my-coc code-of-conduct-ban-list - This will create a new ban list with the shortcode my-coc and an alias of #code-of-conduct-ban-list:example.org. You will be invited to the room it creates automatically where you can change settings such as the visibility of the room.
2. Review the Moderator's Guide.
3. Review !draupnir help to see what else the bot can do.

Legacy documentation (v1.87.0 and below)

For information about the legacy version of Draupnir, see v1.87.0, the documentation for which can be found here.

Contributing & Opening Issues

Draupnir wants to be yours as much as it is ours. Please see or contributing document, but do not worry too much about following the guidance to the letter. And keep that in mind throughout.
