There is no truly free digital signage at any real scale. You can run a single screen for nothing, evaluate a platform for two to four weeks for nothing, or self-host open-source software and pay only in hardware and your own time, but every route to no-cost signage charges you somewhere. There are four routes: vendor free tiers, open-source software, free trials, and do-it-yourself with tools you already own. Each one is free in one place and costs money in another. This page shows where each route is actually free, where the bill starts, and what the cheapest path really costs once you run more than one screen.

Vendor free tiers: real for one screen, not for two

A vendor free tier is real for exactly one screen and breaks the moment you add a second. Yodeck and OptiSigns each offer a free plan that runs a single screen with basic features, which is enough for one lobby display or one menu board that rarely changes. The cost starts at the second screen and at the feature ceiling: scheduling, multiple users, watermark removal, and premium apps sit behind the paid tier, and adding screens puts you on per-screen pricing. ScreenCloud has no free tier at all. A free tier is a real option for one screen and stops being free the moment your deployment grows.

Open source: free to license, not free to run

Open-source digital signage is free to license and never free to run. Xibo and Anthias cost nothing to download, but you pay in server hosting, setup, maintenance, and the technical skill to keep them online, and Xibo in the Cloud is a separate paid product. It fits a team that already runs its own servers and a poor fit for anyone without one, because the hours add up faster than a subscription. For the full tool-by-tool breakdown, see open-source digital signage software.

Free trials: built for proof, not for staying free

A free trial is the cleanest kind of free and the shortest, because it is built to prove the product, not to keep you free. Most signage platforms give you 14 to 30 days of full access, then convert to a paid plan when the timer ends. A trial is the right tool for testing whether a platform fits before you pay, not a long-term way to avoid paying. CastHub runs a 14-day trial with a card on file and nothing charged until it ends, so you can test it on hardware you already own before any money changes hands.

DIY: cheapest hardware, most expensive in time

Do-it-yourself is the cheapest hardware path and the most expensive in time. A Raspberry Pi and an open-source player can drive a screen for the cost of the board, around $50 to $80 once, plus an SD card and a power supply. What you pay after that is your own time: setup, content updates, and fixing it when it freezes, with no central dashboard, no remote monitoring, and no proof that a screen actually played its content. DIY suits a single technical hobbyist who enjoys the tinkering. It does not suit a multi-screen organization, where the upkeep across displays costs more in labor than software would.

The hidden cost of no-cost digital signage

Every no-cost route stops being free at the same place: scale. One screen is cheap on any route. The cost appears when you add the second, the fifth, the tenth, in hardware for each new screen, your time to set up and maintain each one, and, on vendor free tiers, a per-screen price that climbs with every display you add. Per-screen pricing is the wall most buyers hit, because the bill grows in a straight line with your screen count. That is the point where a flat monthly rate that does not change with screen count becomes the cheaper path. For the full hardware and software cost math, see the digital signage pricing guide.

What no-cost digital signage actually costs: a comparison

Once you compare the real monthly software cost at one, five, ten, and twenty-five screens, the flat-rate route is the only one that stops climbing.

Route	What is free	1 screen	5 screens	10 screens	25 screens
Vendor free tier (per-screen above one)	First screen, basic features	$0	about $48/mo	about $108/mo	about $288/mo
Open source, self-hosted	The software license	$0	$0	$0	$0
DIY (Raspberry Pi plus open player)	The software	$0	$0	$0	$0
CastHub flat-rate	Nothing, it is a paid plan	$12/mo	$35/mo	$35/mo	$95/mo

The open-source and DIY rows show $0 in software at every screen count, but that column hides the server hosting, hardware, and labor those routes run on, which no single price can capture. The vendor free-tier figures assume the first screen is free and each added screen runs about $12 a month, a representative rate; actual per-screen pricing ranges from about $8 to $20 depending on the vendor, and some vendors bill every screen once you pass the free one, which makes the paid column climb even faster.

At one screen, a free tier wins at $0 and CastHub does not, which is the honest picture. CastHub Basic is $12 for up to two screens, so it matches or beats a per-screen tier as soon as you add a second screen on the vendors that bill every screen. From around five screens up, the flat rate is the lowest predictable software cost on any route, and the gap only widens: twenty-five screens cost $95 a month on CastHub Enterprise against roughly $288 a month on a per-screen tier. For the complete total-cost math including hardware, see the digital signage pricing guide.

Which route fits your situation

The cheapest route depends on how many screens you run and who maintains them. A single hobby screen with stable content fits a free vendor tier or a DIY Raspberry Pi, where $0 is real and the limits do not matter. A technical team that already runs its own servers fits open source, where the license is free and the maintenance is already someone’s job. A growing organization on a budget, running several screens or more without a dedicated IT team, fits CastHub’s flat-rate plan, which holds at one predictable price as the screen count rises. Each option wins its own lane. To compare specific paid platforms head to head once you have outgrown free, see best digital signage software.

Where CastHub fits: not free, lowest predictable cost

CastHub is not free and not open source, and past one or two screens it is the lowest predictable total cost. You pay a flat monthly rate with no per-screen fees, no setup fees, and no contracts: $12 a month for up to two screens, $35 for up to ten, $95 for up to twenty-five, and $174 once the $79 unlimited-screen add-on covers everything above twenty-five. The fiftieth screen costs $0 more in software than the twenty-sixth, because the CastHub add-on covers every screen above twenty-five at one price. It runs on hardware you likely already own, including Amazon Fire TV, Apple TV, Android TV, Samsung Tizen, LG webOS, and Windows through a browser, so there is no proprietary player to buy. If you want a commercial-grade 4K player, the Amazon Signage Stick is $99.99 on Amazon, and annual Pro plans include one at no cost while annual Enterprise plans include two. You can test all of it on a 14-day trial with nothing charged until it ends. See the plans and the exact price you pay on the pricing page.

Frequently asked questions

Is there truly free digital signage?

Not at any real scale. You can run a single screen for nothing on a vendor free tier, self-host open-source software and pay only in hardware and time, or use a 14 to 30 day trial, but every route charges you somewhere once you pass one screen. Free is real for one screen and ends as you grow.

Is open-source digital signage actually free?

The license is free, the running cost is not. Tools like Xibo and Anthias cost nothing to download, but you pay for server hosting, setup, and ongoing maintenance, plus the technical skill to keep them online. It fits a team that already runs its own servers and little else.

What is the cheapest way to run digital signage long term?

For one screen, a free vendor tier or a DIY Raspberry Pi at $50 to $80 once. For several screens or more, a flat-rate plan is the lowest predictable cost, because per-screen pricing keeps climbing while a flat rate does not. CastHub holds at $95 a month up to twenty-five screens and $174 a month above that with the unlimited add-on.

Does CastHub have a free plan?

No. CastHub starts at $12 a month for up to two screens and runs a 14-day trial, with a card on file and nothing charged until it ends, so you can test it first. It is not free, and past one or two screens it is usually the lowest predictable total cost because there are no per-screen fees.

What is the catch with free single-screen tiers?

The catch is the second screen and the feature ceiling. A free tier runs one screen with basic features, while scheduling, extra users, watermark removal, and more screens move you onto a paid per-screen plan. It is a real option for one screen and stops being free the moment you add another.

What is the cheapest reliable hardware for digital signage?

A Raspberry Pi at about $50 to $80 is the cheapest that works, if you have the time to set it up and maintain it. For a commercial-grade player that boots straight into signage and runs 24/7, the Amazon Signage Stick is $99.99 on Amazon. Both run on screens you already own.
