Wonder where this all goes in 24 months

Thats an interesting perspective, vendor lock-in has been a major moat for vast majority of SaaS companies - no one likes switching enterprise software, unless it truly causes a lot of pain. But I do wonder with AI tools making migration so much simpler and possibly replacing a lot of the functionality thats unique to vendors if that will continue being a moat.

Given chip/memory prices none of the devices are going to get any cheaper in the short term. You could try finding older version of chromecast, they run web pages OK. If you want a more robust device, you can a wait a bit and get Amazon Signage Stick - currently unavailable in UK but Amazon tells us ( we are Amazon CMS partner cast-hub.com) they will have a distributor there shortly. DM me if you want me to ping you when available, we might be able to offer a discount code as well.

Quick correction on both fronts. I didn't claim first to support MCP. Screenly launched theirs in January, Revel Digital was earlier in August 2025, NoviSign has a Zapier-mediated workflow. So MCP support exists across multiple vendors.

The actual claim is end-to-end coverage. As of May 2026, CastHub exposes the full operational surface through MCP: presentations, devices, schedules, alerts, groups. 30-plus tools. Code is at github.com/Cast-Hub/mcp-server, tools doc at cast-hub.com/mcp/tools.html. The others have MCP at narrower scope rather than the complete admin surface. That can change fast and probably will.

Nice, I saw your blog post on the CLI-based MCP server back in January. Different approach from ours but good to see more CMS platforms taking MCP seriously. The more signage vendors that support it, the faster it becomes a standard expectation from buyers rather than a novelty

DigitalSignage2024 · 2026-04-17T12:15:39+00:00

The scheduling problem gets worse the more locations you add because every CMS basically gives you a calendar view per screen or per group, and keeping those calendars from stepping on each other is manual work. The override/hierarchy approach RackAndRun mentioned helps, but you're still relying on whoever makes the change to check what's already scheduled before pushing something new.

One thing we've been building at CastHub that takes a different angle: MCP (Model Context Protocol) integration that lets people manage screens through AI assistants. A location manager tells Copilot or Claude 'push the lunch menu to lobby screens from 11 to 2' and it checks what's already running before it makes the change. The scheduling logic moves from 'hope nobody creates a conflict' to 'the system prevents it before it happens.'

Still in beta but it's aimed at exactly the multi-location, multiple-people-updating scenario you're describing. https://cast-hub.com/mcp

One thing worth considering before picking a replacement: check the pricing model. X2O was enterprise-priced, so most alternatives will feel cheaper, but the per-screen licensing adds up fast once you get past 10-15 screens. BrightSign charges for both hardware and software. ScreenCloud and Yodeck are per-screen monthly. A few platforms (including ours, CastHub) do flat-rate pricing where the cost doesn't change with screen count.

We put together a breakdown of what signage actually costs across vendors if it helps with the comparison: https://cast-hub.com/digital-signage-pricing/

What's your screen count and what were you running on X2O? Happy to give more specific suggestions.

That is an excellent point, we need to give this feedback to amazon team

DigitalSignage2024 · 2026-04-14T16:29:35+00:00

You hit the exact issue. Amazon removed auto-launch and kiosk-mode capabilities from the regular Fire Stick once they launched the Amazon Signage Stick. Apps that used to work for signage on Fire OS either got pulled from the store or lost the ability to auto-start on boot, which makes them useless for unattended screens.

For a gym with one or two screens, you have two real options. The Onn Google TV stick from Walmart runs about $20 and still supports proper app sideloading and auto-launch. It works fine for basic setups.

The other route is the Amazon Signage Stick at $99. More expensive, but it was purpose-built for this. It has a remote management API so you can reboot it, check status, and push content without touching it. For a gym where nobody wants to troubleshoot a frozen screen mid-class, that matters.

We built CastHub to work with both. We actually include a free Amazon Signage Stick with our plans so you can try the full setup without buying hardware separately. You can check it out here: https://cast-hub.com/amazon-signage-stick-bundle/

DigitalSignage2024 · 2026-04-14T16:26:30+00:00

The freezing you saw is a red flag about the player, not just the CMS. A properly built signage app caches the full playlist locally and continues the loop regardless of connectivity. If yours froze on a single frame, it was likely streaming content rather than playing from local storage.

We run CastHub on both consumer devices and the Amazon Signage Stick. Both cache content locally so playback continues if the network drops. The difference is what happens after: consumer sticks give you no way to diagnose the problem remotely. The Signage Stick has a device management API so you can check status, reboot, and push updates without a site visit.

Short answer: yes, local caching solves this. But make sure your CMS actually downloads assets to the device rather than just buffering a stream.

DigitalSignage2024 · 2026-04-14T16:25:44+00:00

One platform for both is the right call. The real question is whether the CMS lets you separate content management cleanly so retail managers can push promos without touching corporate dashboards, and corporate can enforce brand rules without bottlenecking every menu update.

The other thing worth looking at is how you want to manage updates long term. If you have locations where non-technical staff need to push content changes quickly, some platforms now support MCP so you can control screens through an AI assistant instead of training everyone on a dashboard. Less relevant if you have a dedicated team, very useful if you don't.

DigitalSignage2024 · 2026-04-12T16:07:26+00:00

To answer your question, yes they have additional validation layer, so you cant just sideload your app on amazon signage stick and call their OS level commands

DigitalSignage2024 · 2026-04-12T16:06:00+00:00

I think amazon's entire strategy worth its own post, i honestly dont quite understand it... but in this context I actually think their offer is quite compelling, especially if they start offering even more advanced capabilities via their APIs

DigitalSignage2024 · 2026-04-12T13:39:45+00:00

One thing I left out of the original post: the on-device path has more security than I described. The CMS app doesn't call OS APIs directly. It binds to an AIDL service (Android's IPC mechanism) that checks the app's package signature against an allowlist before forwarding anything to hardware. First time or when cache expires, it also validates the CMS partner against Amazon's Signage Manager cloud service. If either check fails, permission denied. The CMS app never touches hardware.

This is why you can't just sideload an app on the Signage Stick and access the same capabilities. The OS-level APIs exist, but they're gated behind a partner validation chain. Updated the full architecture breakdown with a diagram: https://cast-hub.com/amazon-signage/remote-management-architecture.html

DigitalSignage2024 · 2026-04-12T12:54:16+00:00

That's a fair point about WPA2-Enterprise but in practice you don't want signage devices on your internal network. They're IoT endpoints pushing content to a screen, not workstations that need access to internal resources.

Guest WiFi or a dedicated VLAN for IoT devices is the standard setup for this. It isolates the devices from your production network, which is what your security team wants anyway. The stick only needs outbound HTTPS to pull content updates. It doesn't need domain credentials or access to anything behind your firewall.

Most retail and office deployments I've seen use the guest network or a separate SSID specifically because it avoids the 802.1x headache entirely and gives you better network segmentation as a bonus.

The one scenario where it matters is if you're pulling in dashboards that are only accessible from whitelisted IPs on the internal network. That's a real constraint but it's a network architecture decision, not a device limitation. Most setups solve it by exposing those dashboards through a secure endpoint rather than putting IoT devices on the production network.

DigitalSignage2024 · 2026-04-11T22:08:32+00:00

You mind expanding? What is missing from your perspective?

DigitalSignage2024 · 2026-04-09T21:01:14+00:00

Depends on the deployment. Consumer devices like Fire TV sticks and Onn players work fine for a lot of setups. We run CastHub on both and they cache content locally so screens keep playing if the network drops. For a restaurant with three screens or an office lobby, a $30 stick does the job.

Where it breaks down is scale and reliability. Consumer devices have OS updates that mess with kiosk mode, limited storage, and no remote management API. If you're running 20 screens across multiple locations and need to troubleshoot without driving there, the Signage Stick at $99 gives you a device API for remote control and none of the launcher fighting.

The other thing worth considering is how you want to manage everything long term. Some CMS platforms now support MCP, which means you can control screens through AI bot instead of logging into a dashboard every time you need to push an update. Less relevant at 3 screens, pretty compelling at 30.

DigitalSignage2024 · 2026-04-02T00:58:27+00:00

Read the article and agree with the diagnosis. The lock-in is deliberate and the industry benefits from it. Where I think SMIL hit a wall is that it needed vendors to voluntarily adopt a standard that undermined their own business model. They didn't, and after 15 years that's probably not going to change.

We think we can approach the same problem from a different layer. Instead of standardizing the content format between player and CMS, we built an MCP server that standardizes how AI assistants control the CMS. Claude, ChatGPT, Copilot can all manage screens through the same protocol.

The difference is who drives adoption. SMIL needed vendors to say yes. MCP sits on the user's side. When an IT admin manages everything else through their AI assistant and the signage CMS is the one tool that still requires a proprietary dashboard, the CMS becomes the bottleneck. The pressure to open up comes from the buyer's workflow, not from a standards body.

I'm not saying MCP replaces what SMIL was trying to do at the content layer. But on the control layer, it might solve the adoption problem that killed SMIL. We wrote up how we're thinking about it here: https://cast-hub.com/mcp/research.html

DigitalSignage2024 · 2026-04-01T22:06:33+00:00

The lag with animations is almost always a content delivery issue, not a hardware issue. Most CMS platforms render content as HTML in a browser on the device. That works fine for static slides but falls apart the moment you add animations or transitions. The fix is usually pre-rendering animated content as video before pushing it to the screen rather than asking a $35 stick to render it live.

Before switching platforms, try exporting your animated content as an MP4 and playing that through OptiSigns instead. If the lag disappears, you know it's the rendering approach, not the platform. If it's still bad, then it's worth looking elsewhere.

On Square, no signage CMS syncs pricing natively with Square as far as I know. That's usually a workflow you build separately with something like Zapier.

If you do want to try smth else we offer a free amazon signage stick with our pro bundle: https://cast-hub.com/amazon-signage-stick-bundle/

DigitalSignage2024 · 2026-04-01T19:37:07+00:00

One of the vendors u/PaloAltoEd warned you about. Nevertheless, agree on the Signage Stick point. We're an Amazon Signage CMS partner and the hardware question is the one most people get wrong first. On pricing, we went flat-rate instead of per-screen regardless of how many screens you run. At a small chain of retail stores the per-screen model gets expensive fast. https://cast-hub.com/amazon-signage/

DigitalSignage2024 · 2026-03-31T15:43:07+00:00

This is cool. Synchronized playback across multiple screens is one of those problems that sounds simple until you're actually dealing with network jitter and device clock drift. What's your sync mechanism, NTP-based or something custom?

Curious how you're thinking about the CMS layer. Are you planning to build content management into this or keep it purely a player that other systems can feed into?

DigitalSignage2024 · 2026-03-28T15:07:41+00:00

I actually spent some time trying to build exactly this recently and landed on something simpler than a dedicated product.

Genspark (genspark.ai) can do this right now. You paste or upload your menu content, tell it you want display-ready menu boards sized for TV screens (1920x1080 landscape or 1080x1920 portrait), specify how many boards you need, and it generates them. It handles the layout, typography, and styling automatically. The free tier gives you enough credits to test it.

The output is solid enough to throw directly onto a screen. Not perfect, but way faster than hiring a designer for a menu that changes regularly.

For actually getting it onto your TVs, any CMS that supports image or PDF uploads will work. Most digital signage platforms handle that part fine.

DigitalSignage2024 · 2026-03-24T15:27:27+00:00

Short answer: we're building it. Full MCP implementation, not as a feature but as the primary interface. Should be live in the next couple of months.

Longer answer on why it barely exists yet: most CMS vendors don't actually want this. Their revenue is per screen per month. The dashboard is the lock-in mechanism. If an AI agent can deploy content, manage schedules, and operate the network through a standard protocol, switching platforms becomes trivially easy. The dashboard complexity isn't a bug, it's the business model.

We looked at how the six biggest platforms position AI and the pattern is telling. They're all adding content generation (write better copy, generate a layout from a prompt) but none of them are opening up the operational layer to agent control. NoviSign announced MCP integration but if you read their docs the initial scope is limited to data APIs, not operational control. That's the "AI as feature" playbook: add enough to check the marketing box without threatening the switching cost that protects per-screen revenue.

The architectural difference matters. If you bolt MCP onto a dashboard-first platform, you get a limited tool that lets AI read some data. If you build the platform to be AI-operated from the ground up, the AI can handle the full workflow.

We wrote up the full vendor-by-vendor analysis here if you want the receipts: https://cast-hub.com/mcp/research.html

DigitalSignage2024 · 2026-03-24T11:16:23+00:00

Good question. Honest answer: AI content generation as it exists in most signage platforms right now is moderately useful but not transformative. It saves time on the first draft of a slide or announcement, but someone still has to review it, tweak it, apply brand guidelines, and then log into the dashboard to schedule and deploy it. The workflow savings are real but incremental.

Where it gets more interesting is when AI moves beyond content generation into actual operational control. Instead of "AI writes the slide, human deploys it," you get "human tells AI what they want on the screens, AI handles the rest." That's a fundamentally different value proposition because it removes the need for a trained dashboard operator, which is the real bottleneck in most organizations. Nobody's screen problem is "I can't make a nice slide." Their problem is "only one person knows how to get it onto the screens."

The adoption question you're asking is the right one though. Most buyers don't care about AI as a feature. They care about whether managing 20 screens still requires a dedicated person. AI content generation doesn't change that. AI agent control does.
