Cost reality

Self-host free; Element Matrix Services and other hosts are paid.

Pricing and free-tier limits change frequently; re-check official pricing before budget decisions.

Tasks reduced or augmented

Software does not replace community or ops staff. It may reduce or augment:

Encrypted staff rooms
Federated community experiments

Human oversight still needed

Moderation
Federation policy
Server resource use

Risks

Area	Notes
Vendor lock-in	Evaluate export formats and API completeness before deep customization.
Security	Apply updates promptly; restrict admin access; enable TLS.
Compliance	Operator remains responsible for privacy and local regulatory obligations.
Licensing	Synapse AGPL; Element clients have their own licenses.
Operational	Plan backups, monitoring, and a restore drill before production use.

Coworking fit

Roles: technical-operator, community-manager, operations-manager

Workflows: incident-response, community-programming

Problems: self-host-for-data-control, privacy-compliance

Smallest useful experiment

Use a managed Matrix host or small Synapse for one staff room before offering member communities.

Typical time to first value: 1–3 days
