Who it’s for — and when to skip it

Knowledge teams

Use it when collaborative content should remain exportable and under your control.

Skip if required editing, permissions, or migration features are missing.

Community operators

Consider it when customization and transparent moderation workflows matter.

Skip if your team cannot run community safety and support operations.

Distributed teams

Evaluate it when shared content and communication need an open deployment path.

Skip if realtime scale or mobile experience is not proven for your use case.

Strengths and trade-offs

Why teams consider it

Participatory process: Run participatory processes to foster debate, assessment, and decision-making on issues that matter to your community.

Assembly: Create a space for your organization committees, choosing the level of privacy, to manage membership, meetings, or activities.

Initiatives: Collaborate with others to create bottom-up petitions by collecting signatures to achieve a common goal.

Source code and AGPL-3.0-or-later license are visible before adoption

Repository metrics are available for independent review

What to validate

A public repository does not automatically guarantee a documented self-hosting path

GitHub popularity is not a security, quality, or product-fit guarantee

The AGPL-3.0-or-later license still needs review against your distribution and commercial model

Support quality, migration effort, and production hardening vary by project
