Customermates

Follow up on every client conversation. The open-source CRM with LinkedIn and email beside every client, replies drafted by Mate or your own AI agent through MCP, and self-hosting under the AGPL.

Website | Demo | Documentation | GitHub | Film

Customermates helps small teams follow up on every client conversation. LinkedIn and email sit beside each client (on Cloud from Pro also WhatsApp, Instagram and Telegram), and Mate or your own AI agent through MCP drafts each reply and the next step for you to review and send. Underneath is a full CRM for contacts, organizations, deals, services and tasks, with API access, webhooks, n8n automation and MCP.

You can use the managed cloud version or run Customermates yourself in your own infrastructure with Docker Compose.

Product film

The 70 second product film shows the workspace: client conversations from email, LinkedIn and WhatsApp in one inbox, Mate drafting the reply and the next step, and the same records open to Claude, ChatGPT or any agent that speaks MCP.

🐳 Self-Hosting

Self-hosting is two files (docker-compose.yml and .env) plus docker compose up -d. No git clone, no build step. The published image at ghcr.io/customermates/customermates:latest applies pending migrations every time it starts.

Prerequisites

Docker and Docker Compose v2.
A domain name if you want TLS (optional for local).
~2 GB RAM and a couple of GB of disk per thousand records.

Setup

mkdir customermates && cd customermates
curl -fsSL https://raw.githubusercontent.com/customermates/customermates/main/docker-compose.yml -o docker-compose.yml
curl -fsSL https://raw.githubusercontent.com/customermates/customermates/main/.env.selfhost.template -o .env
# edit .env with real values
docker compose up -d

Required .env values:

BETTER_AUTH_SECRET: long random string (openssl rand -hex 32).
POSTGRES_PASSWORD: change the default.
BASE_URL: your public URL (e.g. https://crm.example.com).
RESEND_API_KEY and RESEND_OPERATOR_EMAIL: for signup verification, password reset, and invitation emails.

Optional: uncomment GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET, or AZURE_AD_CLIENT_ID and AZURE_AD_CLIENT_SECRET, to offer sign-in with Google or Microsoft. See Can users sign in with Google or Microsoft?.

Set CRON_SECRET (openssl rand -hex 32) and call /api/cron/lifecycle daily with it, or Trash is never emptied after 30 days. See Which scheduled jobs must I run?.

First boot takes ~1 minute while Prisma applies migrations. Watch with docker compose logs -f app, then open <BASE_URL>/auth/signup.

Day-to-day

docker compose pull && docker compose up -d   # update
docker compose up -d                           # apply .env changes
docker compose logs -f app                     # logs

Front the app with a reverse proxy (Caddy, nginx, Traefik) for TLS and set BASE_URL to the public https:// address. Customermates takes the scheme and host for its links from BASE_URL and sets secure cookies when it uses https://, so X-Forwarded-Proto is not required. The proxy must pass on the original Host header, because the app rejects form submissions whose origin does not match it, including sign-in and sign-up.

🛠️ Development

Create an isolated worktree and run Customermates locally:

git fetch origin main
git worktree add ../customermates-my-change -b feat/my-change origin/main
cd ../customermates-my-change
nvm use
yarn db:provision
cp .env.cloud.template .env
# Paste the printed DATABASE_URL and DIRECT_URL into .env.
yarn install --frozen-lockfile
yarn db:reset
yarn dev

yarn db:provision creates a PostgreSQL 17 container and named volume owned by the current worktree. Re-running it is idempotent. yarn db:reset applies the migrations, seeds the database, and prepares the workflow schemas. Replacing the database volume is destructive and only happens with yarn db:provision --recreate; use yarn db:provision --destroy to remove the worktree's owned database when the worktree is retired.

Useful scripts:

yarn dev
yarn build
yarn lint
yarn openapi:generate
yarn db:provision
yarn db:reset
