Features

Visual timeline — Drag & drop blocks to build your agenda

Automatic time calculation — Start times and durations update instantly

Live mode — Follow your plan in real-time during sessions

Block types & templates — Custom categories, default library, reusable templates

Grouping & breakouts — Parallel sessions, configurable lanes, per-lane facilitators

Share & export — Snapshot links, JSON export/import, print-ready PDF

Offline-first — Works fully offline after first load (PWA)

No registration — All data stays in your browser by default

Self-Hosting

Sessionplan is fully functional without a backend — all data is stored locally in the browser. An optional backend enables the Dynamic Link feature for real-time sync between multiple users.

Dynamic Link (optional backend)

To enable the Dynamic Link feature, deploy a PHP backend that implements the /data/sessions.php REST API (see the API reference). Then set the endpoint URL:

env

# .env
VITE_SESSIONS_API=https://your-server.example.com/data/sessions.php

If VITE_SESSIONS_API is not set, the Dynamic Link toggle is still available in the UI but all requests will fail gracefully — the planner continues to work fully locally.

See ARCHITECTURE.md for the API contract.
