A Sunday with Crater
From the first song to the last amen.
- 9:50
Countdown
A timer counts the room in while people find their seats, and the stage display keeps the time for the band.
- 10:00
Worship
Lyrics go up verse by verse. When the leader goes back to the chorus, Page Up gets you there.
- 10:25
The reading
Type the reference as it is announced. The verse is on the wall before the reader reaches the pulpit.
- 10:35
The sermon
Sermon slides sit in the same schedule, with scripture dropped in wherever the preacher turns.
- 11:20
Closing hymn
One last song, then Ctrl+L puts the logo up while the room empties. The schedule saves as you go.
One laptop, every screen
Every screen in the room, in step.
Add as many outputs as you have screens. Each one mirrors the wall or becomes a stage view, and all of them change on the same key.
The projector
Full screen on the second display, with its own theme and transition.
The stage display
Live text, speaker notes and what is next, with a clock for the band.
The live stream
One NDI source for OBS and other streaming tools, with tally lights.
A TV in the foyer
Open a local address in any browser on the Wi-Fi and the service follows.
Only one screen? Crater can show the output behind the console, the way EasyWorship does.
Themes
Change the whole look in one click.
Crater ships with themes for songs, scripture and slides. Pick one and every slide follows. Make your own in the editor, or send one to the next church as a single file.
Keyboard first
Run the service without the mouse.
Eyes on the stage, hands on the keys. Everything that matters on a Sunday is one or two keys away.

JOHN 3:16 · KJV
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
JOHN 3:17 · KJV
For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
BLESSED ASSURANCE · VERSE 1
Blessed assurance, Jesus is mine! O what a foretaste of glory divine!

Feature requests
Missing something? Ask for it.

Good questions.
Something else on your mind? Read the docs or ask on GitHub.
Is Crater really free?
Yes. Free to download and use on as many computers as you like, with no trial and no licence. The code is open source, so it belongs to the community rather than a company.
Will it run on our old church laptop?
Almost certainly. Crater is built to feel quick on modest machines with 4 GB of RAM. If it runs Windows 10, it will very likely run Crater well.
Do our volunteers need to be technical?
No. If you can put together a slideshow you can run a service. The tutorial playlists walk through each task in a few minutes.
Can we send the screen to our live stream?
Yes. Crater sends its output over NDI, which OBS and most streaming tools already understand. No capture card needed.
Is our information private?
Completely. No accounts, no tracking, no analytics. Your songs and services stay on your computer.
Ready for Sunday.
Pick your computer, run the installer, open your first service. That is the whole setup.
