100 builders.
One weekend.
October.
FaithTech's annual UK weekend hackathon for redemptive technology, rooted in a biblical approach.
Previously run as Kingdom Code.
So, what is a hackathon?
A focused two-day sprint where teams take on real projects using technology, redemptively. You pick up something that matters, join a team, and build a solution to it before the weekend is out.
It runs around the clock. Some teams pace themselves, some build through the night! Either way, there's room for everyone, and you do not need to be technical to take part. Designers, product people, storytellers, product and project managers, first-time coders: the best teams are a mix.
Past teams have built with a real range of tech, including web stacks like React, Laravel, Python, Node.js and Vue.js, mobile apps in Flutter and React Native, and game and 3D work in Unity and Blender, with LLMs and other AI increasingly in the mix.
Use your skills on something that matters.
Around 100 builders gather across roughly 10 teams. You join a team of about 5-10 people, working a real project brought by a charity, church, ministry or individual. A genuine project someone wants to take forward.
By Saturday evening you'll have built something (deployed code, an interactive prototype, a concept design or something else), and met people who share your faith and your craft. This is a weekend to use your gifts where your heart is.
The energy is infectious. You walk in on Friday not knowing anyone, and by the end you've built lasting friendships and something that actually matters.

A decade of building for the Kingdom.
Run previously by Kingdom Code, BUILD is now part of FaithTech, carried forward alongside the Kingdom Code team. The heart of it has not changed: Christians in technology, serving Jesus.
For ten years, BUILD has gathered people to put their skills to work for the Kingdom. Since 2015, this annual hackathon has brought developers, designers and creatives together from across the UK to serve churches, charities and ministries, treating technology as an act of worship, not only problem-solving. Wrapped in prayer and praise across the weekend, teams turn ideas into working tools that reach further than any of us could alone.
- Bible engagement brought to life through reading apps, games and scripture tools.
- Evangelism and discipleship equipped with apps for sharing faith, prayer and growing communities.
- Care for the poor and vulnerable through tools for foodbanks, debt advice, fostering and adoption.
- Global mission extended through translation tools reaching churches worldwide.
Past teams have served partners like Bible Society, Tearfund, Scripture Union, Christians Against Poverty, Compassion and Safe Families. Beyond the projects, BUILD has grown a lasting community of Christian technologists who see their work as worship and service to the church.
