All the WhatsApp surface,
none of the headache.
A developer-first WhatsApp platform that mirrors the Baileys runtime — from QR linking to outbound media — so you can focus on your product.
Unlimited messages
No per-message billing. Your number, your throughput. Internally chunked at 4000 chars with newline-aware paragraph breaking.
Multi-session, multi-tenant
Run 1 to 1,000 numbers from a single API. Each session gets its own auth dir, sandboxed identity, and isolated rate limits.
Real-time webhooks
Inbound text, media, polls, reactions, presence, status — all delivered with HMAC-signed retries.
DM pairing & allowlists
Pairing-by-default keeps unknown senders quiet. Per-account allowlists, group policies, and disable switches.
TypeScript + Python SDKs
Full type-safety, autocomplete, and inline docs. Drop in next to your existing Node, Python, Laravel, or n8n stack.
Open core, self-hostable
Built on Baileys. + Baileys WebSocket layer. Run your own gateway, or let us host. No vendor lock.
Every message type the WhatsApp Web stack supports.
Captions on first media, native reply quoting, emoji reactions, polls.
