Your contacts live in four different address books; Contrack merges Apple, Google, LinkedIn, and Facebook into one self-hosted personal CRM you fully control. Importing merges the address books you already keep, and connecting a calendar or inbox lays past meetings and conversations along each person's timeline. Obvious duplicates merge themselves, borderline matches wait in a side-by-side review with field-level differences highlighted, and every merge can be undone for 90 days. A scribbled note such as 'met at Sarah's wedding, catch up quarterly' turns into fields, tags, dates, and reminders, while optional web research fills in roles and links with cited sources. Each morning, Pulse shows who is due a follow-up, whose birthday lands this week, and which friends have quietly gone a year without contact. Ask Contrack answers plain questions like 'who do I know in Lisbon' or 'who loves natural wine' by searching your notes and contacts locally. The map plots everyone by city, and drawing a loop around a neighborhood before a trip turns a visit into a dinner list in seconds. Households share one server while each profile keeps a private book, and the built-in MCP server lets Claude, ChatGPT, or Cursor look up context and log notes for you. One-click verified backups snapshot the whole address book, passkeys handle sign-in, and open exports mean your data leaves whenever you do.

CRM mechanics applied to your actual relationships instead of a sales pipeline: Nametag is a Personal Relationship Manager (PRM). It exists to fix the things you keep forgetting: when you last talked to an old friend, their kids' names, the birthday you missed twice. Contacts are tracked with flexible attributes - names, birthdays, important dates, and free-form notes for everything else - and organized into custom groups. Where it goes beyond a contacts app is relationship mapping: you define how people connect to each other (family, friends, colleagues, or custom relationship types), and an interactive D3.js-powered graph renders your entire personal network so you can see clusters and connections at a glance. Staying in touch is automated: scheduled reminders fire for birthdays, important dates, and reach-out nudges, with optional email delivery via a Resend API key for password resets and reminder notifications. Built with Next.js, it is mobile-responsive, ships with full dark mode, and supports multiple languages including English and Spanish. Because it is self-hosted, there are no account tiers or contact limits - unlimited people and relationships, with every note about your personal life stored on your own server rather than a social-graph company's cloud. A lightweight, single-container deployment makes it one of the easiest personal tools to run.

Friends drift away when nobody remembers to call; Meerkat CRM is a self-hosted personal CRM that keeps your relationships warm with birthday and stay in touch reminders, contact notes, and a living map of who knows whom. Organize every contact into circles like family, friends, or work, store spouses and children as linked relationships, and see the whole crowd on an interactive network graph that shows how people connect. Sync the same address book two ways: Meerkat runs its own CardDAV server for your phone and can also act as a CardDAV client against an external server you already use. Against each person you can keep the details that matter, dietary habits, kids names, the last conversation, plus a social style timeline of activities you have shared, from dinners to group projects. Reminders nudge you by email when it has been too long, with upcoming birthdays surfaced on the dashboard, so catching up becomes a habit instead of an afterthought. Move data in and out freely: import CSV, VCF, and even a Monica export, export back to CSV and VCF, connect external calendars, and fire webhooks into your own automations. Use it in English, German, Italian, Spanish, or French with light and dark modes, and SSO for whoever shares the house.
