Features

• File Uploading — Drag & drop or browse to upload single/multiple files and folders with real-time progress
• Shareable Links — Each upload generates a unique link for recipients, also as a QR code (saved as a PNG) or through the device's share sheet
• Encryption at Rest — Files are encrypted on the server as they arrive, with AES-256-GCM (chunked, streaming); with a share password the key is derived from it and never stored. It is not end-to-end encryption: the server handles the files unencrypted while they are uploaded and downloaded
• Password Protection — Optionally protect shares with a password
• Expiration — Shares auto-expire after a configurable duration (1 hour to 30 days)
• Download Limits — Set a maximum number of downloads per share
• ZIP Downloads — Download all files in a share as a single ZIP archive
• Auto-Cleanup — Expired shares and files are automatically deleted (hourly)
• Admin Dashboard — View, manage, and delete all shares
• Admin Settings — Configure upload limits, storage quotas, branding, and more
• Site Branding — Custom logo, title, and description
• Colour Profiles — Eight Material 3 colour profiles (Indigo, Blue, Teal, Green, Amber, Rose, Violet, Graphite); the admin picks one for every page, mail and error page
• System Password — Optional global password gate to restrict upload access
• User Authentication — Login, password reset, email verification
• Two-Factor Authentication — TOTP-based 2FA via Laravel Fortify
• Light and Dark Themes — Material 3 Expressive design that follows the system theme, or light or dark by choice
• Setup Wizard — First-run wizard to create the initial admin account

Installation — Development

Docker (recommended)

# Build and start the dev container
docker compose -f docker-compose.dev.yml up -d --build

# View logs (including Vite output)
docker compose -f docker-compose.dev.yml logs -f

The app is available at http://localhost:8000 with Vite HMR on port 5173.

Installation — Production

Docker (recommended)

mkdir sealshare && cd sealshare
curl -O https://gitea.nonameweb.ch/noNameWEB/SealShare/raw/branch/main/docker-compose.example.yml
cp docker-compose.example.yml docker-compose.yml

# Generate an app key and paste it into docker-compose.yml
docker run --rm gitea.nonameweb.ch/nonameweb/sealshare:latest php artisan key:generate --show

# Edit docker-compose.yml — set APP_KEY, APP_URL, and SERVER_NAME
# Then start:
docker compose up -d

Migrations run automatically on startup. Open your configured domain — the Setup Wizard will create the first admin account.

Key environment variables:

Variable	Required	Description
APP_KEY	Yes	Laravel encryption key
APP_URL	Yes	Full URL (e.g. https://share.example.com)
SERVER_NAME	Yes	Domain for auto-TLS (e.g. share.example.com)

Volumes:

Volume	Path	Purpose
sealshare_storage	/app/storage/app	Encrypted uploaded files
sealshare_database	/app/database	SQLite database
caddy_data	/data	TLS certificates
caddy_config	/config	Caddy configuration

Large files:

Uploads beyond the defaults need these limits raised together:

Limit	Where	Default
PHP_UPLOAD_MAX_FILESIZE / PHP_POST_MAX_SIZE	Environment	4G — hard cap per file / per upload batch
Max file size / Max size per share	Admin → Settings	100 MB / 2 GB
LIVEWIRE_MAX_UPLOAD_TIME	Environment	30 minutes per upload
OCTANE_MAX_EXECUTION_TIME / PHP_MAX_EXECUTION_TIME	Environment	300 seconds — encrypting a large file takes a while

Behind a reverse proxy, raise its request body limit and read timeout as well (nginx: client_max_body_size, proxy_read_timeout).

Manual (without Docker)

git clone https://gitea.nonameweb.ch/noNameWEB/SealShare.git
cd SealShare

composer install --no-dev --optimize-autoloader
npm install && npm run build

cp .env.example .env
php artisan key:generate

# Edit .env — set APP_ENV=production, APP_DEBUG=false, APP_URL=https://your-domain.com

touch database/database.sqlite
php artisan migrate --force
php artisan storage:link

php artisan config:cache
php artisan route:cache
php artisan view:cache

Start with Octane:

php artisan octane:frankenphp --host=0.0.0.0 --port=80

Or point your web server (Nginx/Apache) to the public/ directory for a traditional PHP-FPM setup.

Add the scheduler to your crontab:

* * * * * cd /path-to-sealshare && php artisan schedule:run >> /dev/null 2>&1
