Leaven Labs

Leaven Labs

Free, open-source software for churches.

We make small apps that help take care of a church's weekly tasks. They run on your own computer, free of cost.

Projects

What we have made so far

Each app has its own page with downloads and a guide, and its own repository on GitHub.

ChurchRadio Studio

Turn your Sunday service recording into a finished radio broadcast, in one drop.

  • Cuts the organ prelude and ends at the congregation's answer to the dismissal.
  • Fills the rest of the hour with your own songs that fit the church year.
  • Nothing about your services leaves your computer.

Stream Scheduler

Schedules your weekly live streams on YouTube by itself, with the date already in the title.

  • Write the title once. Each week's stream gets its own date, such as "Christmas Eve Service - December 24, 2026".
  • Points a page of your Wix or WordPress site at the coming stream.
  • Alerts you by email, Discord, Slack or Pushover if a stream could not be scheduled or a sign-in stopped working.

How we build

Four promises in every app

  • Free, and it stays free

    Every app is under the MIT License. Any congregation may use it, copy it, change it and share it.

  • Everything stays with you

    The apps run on your own computer. Your recordings never leave it, and sign-ins are kept in the system keychain, never in a file.

  • Written for volunteers

    Plain words, a guided setup, and a light and a dark look. No one needs to be the computer person.

  • Open for anyone to review

    All the code and every change is public on GitHub, with a security policy in each repository.

"The kingdom of heaven is like leaven that a woman took and hid in three measures of flour, till it was all leavened." Matthew 13:33

A little goes a long way. Leaven Labs began with one app, built by Aaron Steger to help churches and shared freely so any congregation can use it.
