If you run a freelance or agency business, you know the pain of juggling five different tools just to keep a client in the loop: a project board here, a file-sharing link there, an invoice sent through yet another app. Atrium puts all of that under one roof — a single branded page where your client can see project progress, download files, and pay an invoice — and because you host it yourself, there's no monthly SaaS bill and no third party sitting on your client relationships. Technically, Atrium is an open-source app (NestJS backend, Next.js/React frontend, PostgreSQL, Prisma) that you deploy with Docker — it supports Docker Compose, Coolify, Portainer, and Unraid out of the box. It handles file storage via S3, MinIO, Cloudflare R2, or plain local disk, takes payments through Stripe, and supports white-label branding with custom domains, magic-link or email/password auth, and role-based multi-tenant access if you're running it for multiple client teams. It's licensed under the Elastic License 2.0 — free and source-available for self-hosting, but you can't resell it as your own competing SaaS.
