About

OpenLP stands for "Open Source Lyric Projection" and is presentation software
developed for churches to provide a single easy to use interface for the
projection needs of a typical worship service. First created in 2004, it has
steadily grown in features and maturity such that is it now a mainstay in
hundreds of churches around the world.
OpenLP can contain a searchable database of songs and Bible verses allowing
them to be projected instantly or saved in a pre-prepared order of service
file. Themes allow for a veriety of presentation options and allow you to add
attractvie visuals to enhance your presentations. PowerPoint and Open Office
presentations, videos, and audio files can be run from within the program
removing the need to switch between different programs. Alert messages can be
displayed so the nursery or car park stewards can notify the congregation easily.
Remote capability allows the worship leader to change songs, or for alert
messages to be sent from anywhere on the network, even via a phone.
Being free, this software can be installed on as many PC's as required, even on
the home PC's of worship leaders without additional cost. Compared to the
expensive site licenses and restrictions of commercial software we believe
OpenLP cannot be beat for value. Still in active development by a growing team
of enthusiastic developers, features are being added all the time, meaning the
software just improves all the time.
