Nodyx

Nodyx is open-source software for running a community forum, chat and voice channels on your own server. It best suits groups that want one independent online home and are prepared to manage its hosting. Its broad toolkit is offered without paid feature tiers, but mobile apps and several integrations are not ready.

Overview

Each installation is a separate community, not a central service for running several communities together. That makes Nodyx a natural fit for an organization building a dedicated space for its members, but not for operators who need a multi-community platform. Independent instances can discover one another through a global directory and relay through NAT using nodyx-relay, while remaining separate communities.

Nodyx is licensed under AGPL-3.0 and described as free forever, with no feature gating or enterprise tier. The trade-off is operational: the community must deploy and run its own installation.

Key features

Forums, chat and voice

Forum tools include categories, threads, rich editing, polls, pinned threads, reactions, thanks and tags. Real-time chat, WebRTC voice channels and screen sharing extend that forum with live interaction, which is useful for communities that want discussion and voice in the same installation rather than separate services.

Customization and private messaging

The Grid Builder supports resizable columns, live previews and theme editing. It also accepts ZIP-uploaded widgets that run in Shadow DOM, giving community operators ways to shape their homepage. The maker says direct messages use ECDH P-256, AES-256-GCM and an ESY layer for end-to-end encryption.

Deployment and security

Deployment options include Docker, a Windows Server PowerShell installer and manual installation on Linux, Mac or Windows. The manual route requires Node.js 22+, PostgreSQL 16+ and Redis 7+. The quick-start installer detects the operating system and installs Node, PostgreSQL, Redis, Caddy and PM2; that simplifies setup, but does not remove the responsibility of running a self-hosted service. Project status also lists TOTP and Signet two-factor authentication and a honeypot suite.

RSS, webhooks, iCal sync and OAuth are marked as coming in v2.2. Communities that depend on those connections now should not choose Nodyx on the assumption they are already available.

Pricing

There are no paid tiers or enterprise tier, so the full platform does not require a higher subscription. The stated price covers the software; Nodyx is self-hosted, so the community still needs to run its installation.

Platforms

Nodyx supports API, Linux, macOS, self-hosted, web and Windows. It has no mobile apps, so communities whose members need a dedicated phone app should look elsewhere.

Who it's for

Nodyx is for community operators who want control of their own forum, chat and voice space, and can take on installation and operation. It is less suitable for groups seeking a hosted multi-community network, mobile apps or ready-to-use integrations such as RSS, webhooks, iCal sync and OAuth.

Pros and cons

Pros

• Full platform at no software charge: the AGPL-3.0 offering has no feature gating or enterprise tier.
• Forums and live interaction together: threads, polls and tags sit alongside real-time chat, WebRTC voice and screen sharing.
• Multiple deployment routes: Docker, a Windows Server installer and manual installation cover several self-hosting setups.
• Homepage customization: the Grid Builder combines layout and theme controls with uploaded widgets.

Cons

• Operators must host it: deployment and ongoing operation fall to the community.
• No mobile apps: the platform does not provide a dedicated app for Android or iOS.
• Several integrations are pending: RSS, webhooks, iCal sync and OAuth are marked as coming in v2.2.
• One community per installation: it does not provide a single multi-community platform.

Alternatives

Verdict

Choose Nodyx if your community wants to operate its own forum, chat and voice installation without software fees or feature gates. Its strongest advantage is the breadth of that combined platform at no charge; its clearest limits are self-hosting, the absence of mobile apps and integrations that are still marked as coming in v2.2.
