Start with SleekFlow — highest vibe code, weakest moat.
Channel.io
Building a simple storefront web chat widget connected to an AI model takes a couple of days with Cursor. Replicating Channel.io requires multi-channel integrations (KakaoTalk, LINE, Instagram DM), low-latency WebSockets, native iOS/Android SDKs, and push notification delivery systems that are complex to maintain in-house.

SleekFlow
Building a unified chat frontend with an LLM fallback is simple, but SleekFlow's core value is native integration with WhatsApp Cloud API, WeChat, and LINE. Maintaining official Meta WhatsApp template synchronization and avoiding phone number bans requires ongoing platform engineering. Self-hosting Chatwoot is a far better path than coding this from scratch.
