Is WAHA free?
Yes! Starting from version 2026.6.1, WAHA is 100% free and open source - all features are available for everyone, with no paid tiers and no separate “Plus” image.
WAHA includes:
- Unlimited 🖥️ Sessions - automate as many WhatsApp Accounts as you need
- Unlimited text and multimedia messages (images, videos, files, etc.)
- All 🗄️ Storages - PostgreSQL, S3 and MongoDB
- Built-in 🔒 Security features
- And everything else that used to be in WAHA Plus
Previously WAHA was distributed in two versions - WAHA Core and WAHA Plus (advanced features available through donations). Since 2026.6.1 everything is part of WAHA Core. See the WAHA Plus page for the history.
