I looked at platforms like HoneyBook, but they are expensive and didn't feel built for developers. I wanted a lightweight, self-hosted, and white-label solution that handled the essentials—file sharing, project tracking, and invoicing—without the SaaS tax. So I built Atrium.
It’s a clean interface that gives clients a single place to track progress and handle billing under my own branding, rather than me stitching together fragmented tools.
Core Features:
* White-Labeling: Fully customizable branding for the client-facing UI.
* Updates & Collaboration: Status updates and file sharing for clients, plus internal notes for team-only coordination.
* Asset Management: Support for S3, MinIO, R2, or local storage.
* Invoicing: Integrated PDF generation and billing.
I’m using this to run my lab’s client operations and would love technical feedback, contributions or feature requests from the community.
