The February 2026 controversy around government identity verification on Discord drove thousands of communities toward self-hosted alternatives — Fluxer reached 125,000 active users in March 2026, according to \u003Ca href=\"https:\u002F\u002Fsinologic.net\u002Fen\u002F2026-04\u002Ffluxer-the-open-source-alternative-to-discord\">sinologic.net\u003C\u002Fa>.

The recommended stack uses Docker and Docker Compose. Plan for 2 vCPU and 2 GB RAM for a light community (up to 100 simultaneous active members).

Pin a version tag in your production Compose, update with `docker compose pull && up -d`, and roll back in one command by reverting the tag. Never use `latest` in production.",{"type":33,"title":60,"body":61},"Who should manage the machine?","Self-hosting Fluxer transfers operational responsibility.
