Why Developers Switch from Twilio
Escape Enterprise Complexity
Twilio's pricing has carrier fees, A2P fees, and hidden charges. Zavu's all-in pricing means no surprises on your bill.
Built-in AI, No Add-ons
Twilio requires third-party AI integrations. Zavu includes AI agents, RAG knowledge base, and flow builder out of the box.
Familiar API, Easy Migration
Similar REST API structure means easy migration. Most developers integrate in under an hour with our migration guide.
All Channels, One Account
Email with Twilio means a separate SendGrid account. Zavu unifies SMS, WhatsApp, and Email in one API and dashboard.
Predictable Costs
No carrier fee surprises. Our per-contact pricing can save 50-80% for high-volume same-user messaging.
Enterprise Ready
Same 99.9% uptime SLA and SOC 2 compliance. Enterprise reliability without enterprise complexity.
Migration FAQ
How hard is it to migrate from Twilio?
Most migrations take a few hours. Our API structure is similar to Twilio's, so changes are minimal. We provide migration guides and can help you port your phone numbers.
Does Zavu have Voice and Video like Twilio?
Not yet. Voice and Video are on our roadmap. If you need Voice today, you can use Zavu for messaging and Twilio for Voice. Many customers do this during migration.
What about Twilio's carrier fees?
Twilio charges carrier fees ($0.003-0.006 per SMS) on top of their per-message rate. Zavu's pricing includes all fees, so what you see is what you pay.
How does Zavu compare to SendGrid for email?
Zavu's email API is built-in, not a separate product. One API, one dashboard, one bill. Great for transactional email alongside your SMS and WhatsApp.
Can I try before fully migrating?
Yes! Most customers run Zavu in parallel with Twilio first. Start with a subset of traffic, verify everything works, then fully migrate when ready.
Do you offer volume discounts?
Yes, for high-volume senders we offer custom pricing. Our per-contact model already saves most users money, but we can do even better at scale.
