Small teams often want collaboration without defaulting to a vendor multi-tenant cloud. This collection groups software that can be self-hosted, fully or partially, so a team can run file sync, photos, passwords, chat, meetings, documents, or local AI on servers and devices they administer.
Self-hosting can reduce third-party access to content, but it increases operational risk if servers are misconfigured. Partial self-hosting may still depend on upstream services. Compare self-hosting support, encryption, and account models on each profile before choosing a stack.
