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 — launched U.S.-only in March 2026 and now worldwide, covering 19 countries with over 422,000 churches mapped.^1
Search and filter by name, 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tracks which congregations offer services in other languages, and makes it easy for anyone to add a church or correct outdated information — no account needed.^1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 summer 2026, over 422,000 churches are mapped across 19 countries — including 244,000+ across all 50 U.S. states, plus national directories for Germany, France, Spain, Canada, the United Kingdom, Australia, Italy, Poland, and more. Every supported country gets its own map and directory pages, the U.S. adds per-state and per-metro directories (60+ metros like Nashville, Des Moines, and Chicago), and a reports hub publishes seasonal snapshots on coverage, denominations, geography, and data quality.^1^6
Started by Derek Castelli, a self-taught designer and believer from Iowa who also created Harvous, a Bible study notes app — Here's My Church now runs as an open-source project under the Harvous umbrella.^1 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's Summer 2026 worldwide report packs in insights: Catholic congregations are the largest share globally at 24.7% (Baptist 11.3%, Lutheran 6.2%), there's roughly one church for every 793 people worldwide, and 46,000+ community corrections have kept listings improving.^6
The whole project is free and open (data licensed CC BY-NC 4.0), with no paid listings, no premium tiers, and no sponsored results — just a tool built to serve the body of Christ.^1
