Matrix server written in Golang.

It intends to provide an efficient, reliable and scalable matrix server service

• Efficient: A small memory footprint with good baseline performance
• Reliable: Implements the Matrix specification as written, using the same test suite as Synapse as well as a brand new Go test suite.
• Scalable: can run on multiple machines and eventually scale to massive server deployments.

This project is a fork of Dendrite : https://github.com/matrix-org/dendrite

See the Planning your Installation page for more information on requirements.

To build Matrix, you will need Go 1.24 or later.

For a usable federating Matrix deployment, you will also need:

• A domain name (or subdomain)
• A valid TLS certificate issued by a trusted authority for that domain
• SRV records or a well-known file pointing to your deployment

The Federation Tester can be used to verify your deployment.

If you wish to build a fully-federating matrix instance, see the Installation documentation. For running in Docker, see build/docker.

The following instructions are enough to get matrix started as a non-federating test deployment using self-signed certificates and SQLite databases:

$ git clone https://github.com/antinvestor/matrix
$ cd dendrite
$ go build -o bin/ ./cmd/...

# Generate a Matrix signing key for federation (required)
$ ./bin/generate-keys --private-key matrix_key.pem

# Generate a self-signed certificate (optional, but a valid TLS certificate is normally
# needed for Matrix federation/clients to work properly!)
$ ./bin/generate-keys --tls-cert server.crt --tls-key server.key

# Copy and modify the config file - you'll need to set a server name and paths to the keys
# at the very least, along with setting up the database connection strings.
$ cp dendrite-sample.yaml matrix.yaml

# Build and run the server:
$ ./bin/dendrite --tls-cert server.crt --tls-key server.key --config matrix.yaml

# Create an user account (add -admin for an admin user).
# Specify the localpart only, e.g. 'alice' for '@alice:domain.com'
$ ./bin/create-account --config matrix.yaml --username alice

Then point your favourite Matrix client at http://localhost:8008 or https://localhost:8448.

This means Matrix support amongst others:

• Core room functionality (creating rooms, invites, auth rules)
• Room versions 1 to 12 supported
• Backfilling locally and via federation
• Accounts, profiles and devices
• Published room lists
• Typing
• Media APIs
• Redaction
• Tagging
• Context
• E2E keys and device lists
• Receipts
• Push
• Guests
• User Directory
• Presence
• Fulltext search

We would be grateful for any help on any issues you can contribute to.

We are prioritising features that will benefit massive deployments rather than homeservers. More effort is required on features including :

• OpenID,
• Guests
• Admin APIs
• AS API
