Free Mosque Display Systems: What's Available and What Actually Works
Why every mosque needs a digital display in 2026
Walk into most mosques today and you will still see a printed A4 sheet taped to the wall with prayer times. Maybe it is a laminated monthly timetable from the local Islamic bookstore. Maybe someone updates a whiteboard before Fajr each morning.
The problem is obvious: these systems depend on a single volunteer who may get sick, travel, or simply forget. When Ramadan hits and times shift every day, the burden multiplies. Congregants check their phones anyway because they do not trust that the posted times are current.
A digital display on a TV screen solves this permanently. Once configured, it pulls accurate prayer times automatically, adjusts for daylight saving changes, and shows iqama times that the imam can update from his phone. No more crossed-out numbers with marker pen. No more "Brother, is Maghrib at 5:47 or 5:48 today?"
The good news is that you do not need a big budget to make this happen. Several free options exist, and for most small to medium mosques, a free tier is more than enough.
What a mosque display system actually does
Before evaluating free options, let us clarify what a mosque display system should handle:
Core features
- Automatic prayer time calculation based on your location and preferred calculation method (ISNA, MWL, Egyptian, Umm al-Qura, etc.)
- Iqama time display that your admin can update remotely
- Next prayer countdown so congregants can see at a glance how long until the next salah
- Date display in both Gregorian and Hijri calendars
- Jumuah time shown prominently on Fridays
Nice-to-have features
- Announcement ticker for community notices
- Custom branding with mosque name and logo
- Multiple display themes or color schemes
- Automatic brightness adjustment for day/night
- Ramadan mode with suhoor and iftar times
Free options available for mosques
Option 1: DIY with a web page
The most basic approach is to create a simple HTML page that calculates prayer times using a JavaScript library like Adhan.js or PrayTimes.js. You host it on a free platform (GitHub Pages, Netlify, Vercel) and open it in a browser on your TV.
Pros: Completely free. Total control over design. No dependency on any service.
Cons: Requires a developer to build and maintain. No admin panel for the imam to update iqama times. If something breaks, your tech volunteer has to fix it. No mobile-friendly management interface.
Best for: Mosques with an active tech volunteer who enjoys building things.
Option 2: Google Slides or PowerPoint on a loop
Some mosques use a Google Slides presentation displayed on a TV via Chromecast. Volunteers update the slides weekly or monthly.
Pros: Free. Familiar interface. Anyone can edit.
Cons: Times do not update automatically. Someone must manually change times. No countdown feature. Looks unprofessional. Can show stale data for days before anyone notices.
Best for: Mosques that only need a static display and have dedicated volunteers to update regularly.
Option 3: Open-source mosque display projects
Several community-developed open-source projects exist on GitHub. These typically require a Raspberry Pi to run and offer basic prayer time display functionality.
Pros: Free software. Customizable if you have development skills. Community-supported.
Cons: Requires technical setup (Linux, SSH, configuration files). Hardware cost for Raspberry Pi. Limited support if something goes wrong. May not be actively maintained. Updates require manual intervention.
Best for: Tech-savvy mosque committees willing to invest setup time.
Option 4: Purpose-built free tiers (like AzanCast)
Several mosque-focused platforms offer free tiers specifically designed for masjid displays. AzanCast, for example, provides a permanently free option that includes automatic prayer time calculation, iqama management, and a display URL you can open on any TV with a browser.
Pros: No technical setup required. Admin dashboard for easy management. Automatic updates. Mobile-friendly management. Professional appearance. Built specifically for mosques.
Cons: Dependent on the service staying online. Some advanced features (like custom announcements or multiple display themes) may require a paid upgrade.
Best for: Most mosques. Especially those without dedicated tech volunteers.
What to look for when evaluating free mosque display software
Not all free options are created equal. Here is what matters:
1. Does it actually stay free?
Some services advertise a free trial that expires after 14 or 30 days. That is not a free tier, that is a sales funnel. Look for platforms that explicitly offer a permanently free option for basic mosque display needs.
AzanCast's free tier does not expire. You get prayer time calculation, iqama management, and a display URL at no cost, indefinitely.
2. Who updates iqama times?
This is the most important practical question. If your imam decides to shift Isha iqama from 8:30 to 8:45 next week, how does that change reach the TV?
With a DIY solution, someone edits code or a file on a server. With a purpose-built system, the imam or admin opens an app, changes the time, and it appears on the display within seconds. The easier this workflow is, the more likely your system will actually stay current.
3. How does it handle calculation methods?
Your community might follow ISNA angles, or the Islamic Society of North America method, or the Muslim World League method. Some mosques use the Hanafi calculation for Asr. Make sure whatever system you choose supports your preferred method and allows fine-tuning of angles if needed.
4. What happens during power outages?
TVs restart after power outages. Does your display system automatically reload, or does someone need to physically walk to the TV and reopen a browser? Good systems either auto-launch on boot or provide instructions for setting this up.
5. Is it readable from the back of the prayer hall?
A display that looks great on a laptop screen might be unreadable on a 43-inch TV viewed from 15 meters away. Purpose-built mosque display systems are designed with large font sizes and high contrast specifically for prayer hall viewing distances.
How AzanCast's free tier works
Since this comes up often, here is a straightforward explanation of what you get with AzanCast at no cost:
Setup: Register your mosque at myazancast.com/mosques. Enter your mosque name, address, and time zone. Choose your calculation method. Set your iqama times.
Display: You receive a unique display URL. Open this URL on any device with a web browser — Fire TV Stick, Chromecast with Google TV, smart TV browser, Raspberry Pi, old laptop connected to a TV. The display shows prayer times, iqama times, countdown, and dates.
Management: Log into your admin dashboard from any device. Update iqama times, and they appear on the display immediately. No app installation required.
What's included free:
- All five daily prayer times calculated automatically
- Iqama time management
- Next prayer countdown
- Hijri and Gregorian date
- Jumuah time display
- Basic display theme
What requires an upgrade:
- Custom announcement ticker
- Multiple display themes
- Custom logo and branding
- Priority support
For a mosque that simply needs accurate prayer and iqama times on a TV screen, the free tier is genuinely sufficient. You are not getting a crippled product designed to force an upgrade.

Making the decision for your mosque
Here is a simple decision framework:
Choose DIY if you have a reliable developer in your community who will maintain the system for years (not just set it up and disappear after Ramadan).
Choose a purpose-built free tier if you want something that works out of the box, can be managed by non-technical board members, and will not break when your one tech volunteer moves cities.
Avoid Google Slides unless you genuinely cannot get internet connectivity to the TV and need an offline-only solution updated manually.
The reality for most mosques is that the bottleneck is not money but volunteer time. A system that costs $0 but requires hours of maintenance every month is more expensive than a genuinely free system that runs itself.

Frequently asked questions
Is the free tier really free forever, or is it a trial?
AzanCast's free tier is permanently free. It is not a trial that expires. You get prayer time calculation, iqama management, and a working display URL indefinitely. The free tier exists because we believe every mosque deserves accurate prayer time displays regardless of budget.
What if I start on the free tier and want to upgrade later?
You can upgrade at any time without losing your settings or display URL. All your iqama times, configuration, and display preferences carry over. Your display URL stays the same, so you do not need to reconfigure your TV.
Can I use a free mosque display system on multiple TVs?
Yes. Your display URL can be opened on as many devices as you want simultaneously. If you have one TV in the main prayer hall, one in the sisters' section, and one in the lobby, they all show the same synchronized information from the same URL.
Do I need internet for the display to work?
Yes, the TV needs an internet connection to load and refresh prayer times. However, most mosque display systems (including AzanCast) cache data locally, so a brief internet outage will not blank your screen. The display will continue showing the last loaded times until connectivity returns.
