Castit as an OptiSigns alternative
OptiSigns and Castit both run screens from the cloud. OptiSigns suits a team that signs up online, buys one of its players or brings its own device, and wants every price on the website. Castit suits organizations that want certified partners to install and support their screens, with e-paper displays on the same dashboard.
OptiSigns in brief
OptiSigns describes its product as digital signage made easy: software that turns any screen or TV into digital signage. It is a cloud service, founded in 2016 and based in Houston, Texas.
It sells its own players, the OptiStick, Pro, and ProMax, and lists Windows, macOS, Linux, Android, Raspberry Pi, Apple TV, ChromeOS, BrightSign, LG webOS, and Samsung commercial displays among its other platforms, plus a web player. OptiSigns publishes its prices per screen, has a free plan for up to three screens and a 14-day free trial, and lists offline playback, proof of play, and interactive kiosks among its features, with an on-premise or private cloud option on its Enterprise plan.

What Castit brings
Castit is built to be delivered and supported by partners, and to cover more of the building than the screens.
- Certified partners scope the setup, install the screens, and come on site, with Castit behind them for second-line support.
- Wireless e-paper displays, for meeting-room doors, shelf edges, and the places a screen can't go, are managed from the same dashboard as the screens.
- Your data is hosted in the EU.
- Castit is part of GuideLites, whose platform also handles visitor registration and meeting-room booking, so you can add either one when you need it.
When OptiSigns may suit you better
If you want to sign up online, buy a ready player from the same company, and see every price before you talk to anyone, OptiSigns is set up for exactly that.
It also sells a range of players and kiosks of its own, and offers an on-premise or private cloud option on its Enterprise plan. Castit runs only in the cloud, so there is no server for you to install or maintain. Interested in self-hosting? Talk to us.
Castit's free plan, Essential, is self-serve too: 21 days of the complete product on up to ten players, then one player that keeps running for free. Castit's Professional plan is priced on request, and partner-delivered setups are scoped in a demo or with a certified partner.
Questions to ask both
The answers matter more than any feature list, so put the same questions to each.
- Who installs the screens, and who comes on site when one fails?
- Does it run on the screens and players you already own?
- What happens when the network drops, and for how long do screens keep playing?
- Where is your data stored, and on which plan?
- Do you need e-paper, room booking, or visitor registration?
- Which features, such as proof of play, are on which plan?
Castit and OptiSigns: common questions
Can I start with Castit for free, as with OptiSigns' free plan?
Yes. Castit Essential starts with 21 days of the complete product on up to ten players, with no credit card. After that one player license stays free for as long as you like, with up to 5 items per screen, up to 30 seconds per item, and the Clock, Weather, and PDF Viewer apps. OptiSigns' free plan covers up to three screens. See what Essential includes.
How is Castit priced, next to OptiSigns?
Castit is licensed per player. Essential keeps one player free, Professional is priced on request, and a partner-delivered setup, with installation, certified hardware, and on-site support, is quoted for your project. OptiSigns publishes its prices per screen on its website. See Castit's plans.
Do I have to buy a player from Castit?
No. Castit runs on Android, Samsung Tizen, LG webOS, Windows, Linux, the Web Player and the Castit Android player, so you can use the screens and players you already own. When you want a setup that is supported end to end, a certified partner supplies the Castit Android player, preconfigured. See supported hardware.
Can I keep my screens if I move from OptiSigns?
Often, yes. Castit runs on screens you already own and on mixed fleets, so you can switch in phases. A certified partner can check your players and plan the move, or bring your setup to a demo and we will show you the same screens running on Castit.
