Monica

The open-source personal CRM

Visit Monica

Monica is an open-source personal CRM designed to help individuals keep track of friends, family, colleagues and other people in their lives. It stores details such as important dates, previous conversations, notes, activities, gifts, debts, promises and reminders to get back in touch, keeping relationship information in one private place rather than across messaging apps.

Core features include contact management with a dashboard, journal entries, reminders (including automatic birthday reminders), relationship mapping between people, gifts and debt tracking, custom fields and sections, and file attachments. It offers a REST API for automation and data import/export via vCard and CSV. The web application works on phones, tablets and desktops; native iOS and Android apps are planned for the upcoming v3 release, which will also add an MCP server for connecting external assistants to your data.

Monica is packaged in two ways: a hosted subscription with a single plan covering unlimited contacts, notes, reminders and activities, with managed backups, automatic updates and email support, available on a 30-day trial; or free self-hosted installation on your own server, where you manage infrastructure and receive community support. It is suited to individuals rather than sales teams, with no per-contact or per-user pricing.
