Open-source personal relationship management for documenting your life
Monica is a web application that helps you organize and document interactions with family and friends. Think CRM for your personal relationships, not a social network.
Monica is an open-source Personal Relationship Management (PRM) system designed to help you remember and organize the details of your interactions with the people who matter most. Unlike social networks, Monica is private—built for your eyes only.
Ideal for anyone who wants to strengthen relationships by documenting life events, conversations, and important details. Monica has proven especially valuable for people with Asperger syndrome, Alzheimer's disease, and introverts who benefit from structured relationship tracking.
Manage contacts with detailed relationship mapping, set automatic birthday reminders, log activities and tasks, maintain a personal diary, upload photos and documents, and organize everything with labels and custom fields. Monica supports multiple vaults, users, and 27 languages. It's self-hosted, giving you complete control over your data without tracking, ads, or AI integrations scanning your information.
Monica does one thing exceptionally well: helping you maintain more meaningful relationships through thoughtful documentation.
When teams consider Monica, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Maintaining Long-Distance Friendships
Log conversations, set reminders for check-ins, and remember important life events to stay meaningfully connected across time zones.
Managing Extended Family Relationships
Track birthdays, anniversaries, gift ideas, and family tree connections in one private, organized system accessible to multiple family members.
Supporting Memory-Related Conditions
Provide structured documentation for individuals with Alzheimer's or Asperger syndrome to recall relationship details and interaction history.
Professional Networking Without Social Media
Document professional contacts, meeting notes, and follow-up tasks while maintaining complete privacy outside corporate CRM systems.
