Tesserae

Tesserae is a self-hosted dashboard server for e-ink displays. It is meant for composing dashboards in a browser, rendering them server-side, and pushing the resulting frames to Raspberry Pi, ESP32, Kindle, and TRMNL-compatible panels.

The browser editor supports live preview, and the interface shown on the page includes theme, style, and matting controls, a resizable cell grid, per-device targeting, and an instant render preview. The product also states that it includes 30+ widgets, a theme builder, scheduling, and rotations, and that dashboards can be pushed to every panel with one click. Example dashboards on the page include weather, transit, home status, dev metrics, now-playing, analytics, calendar, tasks, and related information.

Tesserae is delivered as a self-hosted system with no hosted version. It can be run on the user's own hardware, and the page lists several installation paths: one container, a one-line script, a Home Assistant app, an LXC container, or direct from source. It also says there is no account required, no cloud required, and no tracking. For device setup, the page describes a Raspberry Pi client that uses REST and no broker, and a Seeed reTerminal E1003 flow that uses a browser flasher over Web Serial and a setup portal. The hardware section and quick start examples name Raspberry Pi, ESP32, Kindle, TRMNL-compatible panels, Seeed reTerminal E1003 and E1004, and Waveshare 7.3" PhotoPainter panels.

The project is open source and is licensed under AGPL-3.0-or-later. The page also identifies a GitHub repository, a docs site, an editor demo, version v0.100.0, 195 GitHub stars, 16 verified panels, 1,140 passing tests, and 3 contributors.
