Open Source Digital Signage Software: Free & Self-Hosted (2026)

Open source digital signage lets you own your content, skip per-screen subscription fees, and run your screens on your own terms. Here is what it means, why it matters, and how Nex-Gen OOH fits in.

What is open-source digital signage?

Open-source digital signage is signage software whose source code is publicly available under a permissive license, so anyone can inspect, run, modify, and redistribute it. Instead of renting access to a closed cloud platform, you get the actual application - the content management system (CMS) that schedules and pushes content, plus the players that run on your screens.

Nex-Gen OOH is an open-source digital signage CMS released under the MIT license. That license is about as permissive as it gets: you can audit the code, fork it, extend it, and deploy it commercially with no strings attached. You can run it as a managed cloud service or self-host it on a server you control - the same codebase either way.

Why choose open source over cloud SaaS?

• Data ownership. With a self-hosted open-source deployment, your content, schedules, device list, and logs live on infrastructure you control - not in a vendor's cloud. For healthcare, finance, government, and education, that is often a hard requirement.
• No per-screen fees. Closed SaaS products charge a recurring fee for every screen, typically $5-15/screen/month. Self-hosting Nex-Gen OOH replaces that with a flat server cost - a $5 VPS can run hundreds of screens.
• No vendor lock-in. If a cloud vendor raises prices, pivots, or shuts down, your deployment goes with it. With MIT-licensed source you own your copy and control your own roadmap.
• Auditable and MIT-licensed. You can read every line, run a security review, and satisfy procurement teams that need to know exactly what runs on the network.
• Self-host or cloud. Open source does not force you onto your own servers. Start on the hosted free plan to evaluate, then self-host when you are ready - or stay on the cloud if you prefer managed hosting.

What Nex-Gen OOH gives you

Nex-Gen OOH is a full digital signage platform, not just a media player. Everything below is in the open-source project:

• Content and scheduling: playlists, scheduling and dayparting, content expiry, and multi-zone layouts.
• Multi-screen: video walls with multi-screen sync, group sync, kiosk mode, and offline-native playback that keeps running when the network drops.
• Management: live remote control (Android players, with accessibility permission), auto-update/OTA, telemetry, a public API with scoped tokens, an agency portal, and white-label / reseller support.
• Every player is free: Android TV / Fire TV (native APK), Samsung Tizen (.wgt), LG webOS, Amazon Vega OS, Raspberry Pi (free setup script), and Windows / ChromeOS / any browser via the web player.
• Native widgets: YouTube, RSS, Weather, Clock, Text/HTML, Social, and a Directory-board. A universal Webpage widget embeds any framable public URL - published Google Slides, Canva, Power BI, and live dashboards. See all integrations.
• Self-host switch: set SELF_HOSTED=true to unlock the enterprise plan, disable subscription and Stripe checks, and run unlimited devices for free.

Open source vs the paid SaaS incumbents

The dominant hosted products - Yodeck, ScreenCloud, OptiSigns - are closed, cloud-only, and billed per screen. Here is how an open-source CMS compares:

How Nex-Gen OOH compares to other open-source options

Nex-Gen OOH is not the only open-source signage project - the two best-known alternatives are Xibo and Anthias (formerly Screenly OSE).

vs Xibo: Xibo is open source on the server side, but its player apps are not all free - the Android, Tizen, and webOS players are paid licenses. With Nex-Gen OOH every player is free on every platform. See the Nex-Gen OOH vs Xibo comparison.

vs Anthias: Anthias is a lightweight single-screen player built for one Raspberry Pi at a time, without a true multi-device fleet CMS. Nex-Gen OOH is a modern multi-device platform - manage Android TV, Fire TV, Tizen, webOS, Vega, Pi, and browsers from one dashboard. See the Nex-Gen OOH vs Anthias comparison.

Getting started

The fastest path is the hosted free plan - one device, no server to run. When you are ready to self-host, clone the repo:

git clone https://github.com/screentinker/screentinker.git
cd screentinker/server
npm install
cp .env.example .env
# edit .env with your domain, JWT_SECRET, and SELF_HOSTED=true
node server.js

Nex-Gen OOH runs on Node.js with a SQLite database, so a $5 VPS is enough to manage hundreds of screens. Full deployment details are in the GitHub README, and the self-hosted guide walks through reverse proxy, TLS, and backups.

Frequently asked questions

Is Nex-Gen OOH really free and open source?

Yes. Nex-Gen OOH is released under the MIT license, so the full source code is public and you can audit, fork, and extend it. Self-hosting is free with unlimited devices; the managed cloud has a free plan plus paid tiers if you prefer hosted convenience.

What does the MIT license let me do?

The MIT license lets you run, modify, and redistribute the software - including commercially - with essentially no restrictions beyond keeping the copyright notice. You can build custom widgets, integrate it into your own systems, and white-label it.

Do I have to self-host to use open-source digital signage?

No. Open source means the code is available if you want it, but you can still use Nex-Gen OOH's managed cloud. Many teams start on the hosted free plan and self-host later once their screen count grows.

Are all the player apps free?

Yes. Android TV / Fire TV, Samsung Tizen, LG webOS, Amazon Vega OS, Raspberry Pi, and the browser-based web player are all free on every platform, with no per-player license.

How is Nex-Gen OOH different from Xibo?

Both are open source on the server, but Xibo charges license fees for its Android, Tizen, and webOS players. Nex-Gen OOH keeps every player free on every platform.

How many screens can a self-hosted server handle?

Nex-Gen OOH runs on Node.js and SQLite, which is efficient. A small $5/month VPS can comfortably manage hundreds of screens; larger fleets just need a bit more CPU, RAM, and storage.
