Looking for a church in a new city, or just curious about what's nearby? Here's My Church is a free interactive map of Christian churches across all 50 U.S. states, built to be the most accurate church directory out there.^1
Search and filter by denomination, size, or language, and see details like address, website, and service times. What sets it apart from other directories: it estimates weekly attendance for each church using building footprint data and denomination benchmarks, tracks which congregations offer services in other languages, and makes it easy for anyone to add a church or correct outdated information — no account needed.^1
The data blends public records from OpenStreetMap, the U.S. Census, and the Association of Religion Data Archives (ARDA), then gets better over time through community submissions that are reviewed before going live.^1 As of mid-2026, over 244,000 churches are mapped — roughly 64% of an estimated 380,000 churches nationwide.^1
Started by Derek Castelli, a self-taught designer and believer from Iowa who also created Harvous, a Bible study notes app.^3 The idea came from a 3 a.m. text from a friend, and within 48 hours the project was live and growing — built with React, Supabase, and an AI-assisted workflow using Claude.^4
The project published its inaugural State of Churches in America report, packed with insights: Baptist congregations make up the largest share at 18.4%, there's roughly one church for every 1,371 Americans, and an estimated 43.7 million people attend services weekly across the country.^2 Mississippi has the highest church density per capita, while Nevada has the lowest.^2
The whole project is open source under a CC BY-NC 4.0 license, with no paid listings, no premium tiers, and no sponsored results — just a tool built to serve the body of Christ.^1
