Just three things: 1) A Twilio account (free to create), 2) A Twilio phone number ($1-2/month), and 3) Your web browser. That's it! No downloads, no special hardware, no complicated setup.
DialSheet includes built-in lead management and CRM features. For integration with other systems, you can use our API or export/import data via CSV. Since it's open-source, you can also build custom integrations.
Unlimited! Unlike other platforms that charge per user, DialSheet supports unlimited team members at no cost. Each user connects their own Twilio account for complete cost transparency.
Absolutely. We use AES-256 encryption for sensitive data, Supabase for SOC 2 compliant hosting, and row-level security to isolate user data. All API credentials are encrypted at rest.
Yes! DialSheet is fully open-source. Download the code from GitHub and host it on your own servers for complete control. Or use our free hosted version at dialsheet.io.
