Overview

Fluxer is an AGPLv3 communication platform for text chat and VoIP across friends, groups, and communities. Its self-host stack can run the web app, HTTP API, Gateway, admin dashboard, uploads, search, and voice signalling as one Docker Compose project. GitHub's latest release is a `fluxer-api` component release, so it is not treated as a product-wide version.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Operate messaging and voice in one community platform

The repository positions Fluxer around instant messaging and VoIP, while the operator guide describes a Compose stack containing the web app, API, Gateway, admin dashboard, uploads, search, and voice signalling. Built with shows TypeScript from GitHub metadata.

Sources: [1][2][3]

Use a checksum-verified installer to generate secrets, Compose files, and TLS configuration

The official operator guide downloads the installer and its SHA-256, verifies it, then runs it with the target domain and contact email. Bundled Caddy can obtain TLS certificates, and the installer supports dry-run and external-proxy modes.

For communities that want Discord-like chat and voice on infrastructure and domains they control

It fits operators who want community accounts, channels, voice, and media on their own infrastructure while controlling registration and instance policy.

Finish first-run setup immediately after exposing DNS and ports

The operator guide warns that fresh-instance registration defaults to open and that the first registering account can reach configuration before setup is closed. Complete the wizard in the same sitting that makes the host public. The stack also needs roughly 8 GB RAM minimum, voice ports, TLS, backups, and update operations. The latest GitHub release name is an API-component version, not a product-wide semantic version.

Supplemental curator note

The installer handles secrets and TLS, but a fresh public instance has a registration/setup exposure window. Finish the wizard immediately after publishing DNS and ports.

Try it in 3 steps

  1. 1

    Prepare DNS and Docker requirements

    The official guide assumes about 8 GB RAM, 20 GB disk, ports 80/443, and voice ports 7881/7882 among its baseline requirements.

    Docker 24+ / Compose 2.20.2+ → Point your domain DNS to the host
  2. 2

    Verify the installer

    Confirm the checksum, read the installer, and use `--dry-run` if you want to inspect the plan first.

    curl -fsSLO https://fluxer.dev/install.sh && curl -fsSLO https://fluxer.dev/install.sh.sha256 && sha256sum -c install.sh.sha256
  3. 3

    Install and finish the setup wizard

    Replace the domain and email. A fresh instance starts with open registration, so complete the first-admin wizard in the same session that exposes DNS and ports.

    sh install.sh --domain chat.example.com --email you@example.com → Complete Setup Wizard
