OpenFamily vs OtoZen

OpenFamily is a free, open-source, self-hosted GPS tracker for household location sharing. Its live map shows family members with photo avatars, battery levels, last-seen times, and movement states, with updates through WebSocket. Saved places can trigger arrival and departure alerts. Safety tools include SOS with a ten-second countdown, check-ins with notes, and non-emergency requests for family help. Location history includes map trails, place stays, stops, and in-transit segments; detailed history is retained for 90 days. People join using invite codes and can be assigned admin, member, or child roles. A web admin panel manages accounts and families, creates invites, configures optional SMS, downloads the Android APK, and displays the map. OpenFamily runs as a Docker Compose stack on a VPS, Synology NAS, home server, or LAN machine. It supports Android, iOS, web, API, and self-hosted use. Account and location data are stored in PostgreSQL on the operator's server; default map tile hosts can see the area being viewed.

OtoZen is a family location-sharing and driving-safety app for Android and iOS. When location sharing is enabled, family members can view a driver's live location, speed, posted speed limit, and estimated arrival time during a trip. Other features include places alerts, speeding and phone-use alerts, past drives, SOS response, and student-driver logs. Trip reports and Drive Scores provide driving insights, while weekly drive-score reports are a premium feature. Automatic crash response can connect supported users in the USA with a trained agent who coordinates with local emergency services; student-driver DMV logs are also available only in the USA. Users control who can see their location and arrival time, and can stop sharing or change visibility for a person. OtoZen says trips and other listed drive and commute information are stored on the mobile device, not in the cloud. It says it does not share user data with advertisers, police, or insurance companies; its privacy policy also allows sharing with service providers such as Firebase. The Free Plan is free. Family Plan is $49.99 a year, and Family Plus Plan is $64.99 a year.
