A developer-first alternative to Twilio Conversations — built for modern messaging.
RCS-first, AI-native, and built to scale.
POST /conversations
{
"participants": ["+1234567890", "+0987654321"],
"metadata": { "agent_id": "support-bot" }
}
Built for the modern messaging landscape
Twilio Conversations doesn't support RCS. Konvos does — natively.
Optimized for LLM and AI-agent workflows — from message authorship to structured fallback logic.
REST-first. No weird SID spaghetti. Just clean JSON, phone numbers, and endpoints that make sense.
Supports group MMS, 1:1 SMS fallback, and delivery/read receipts. Architected for scale.
Three simple steps to get started
POST /conversations
Initialize a new conversation with participants and metadata.
POST /conversations/:id/participants
Add phone numbers and assign roles to conversation participants.
POST /conversations/:id/messages
Send RCS-rich messages with automatic SMS/MMS fallback.
Konvos is built by devs, for devs. Our REST API is fully documented and ready to test. Start building your messaging-based app with agent-native primitives today.
We're in private beta with select teams building AI-native messaging platforms.
