Twilio is the best-known global messaging API, with no monthly platform fee and pure usage-based pricing, but no built-in chatbot, inbox or CRM: you build the entire application layer yourself.
Figures reflect Twilio's publicly available 2026 pricing and positioning where published. Providers change rates and plans often, so check their live page before you decide.
Twilio is the platform most developers think of first for programmable messaging, and its WhatsApp pricing is genuinely simple: no monthly subscription, pay-as-you-go, Meta's own message fees passed through plus a small Twilio fee of about $0.005 per message. For a company with an engineering team that wants full control over the application layer, that is an honest, flexible starting point.
The trade-off is that Twilio gives you infrastructure, not a product. There is no chatbot builder, no team inbox, no CRM, no automation canvas: you are expected to build all of it yourself on top of the API, which means a real software project with real engineering time before a single customer conversation is automated.
WA.Expert is the finished product: the same underlying WhatsApp Business API access, but with the chatbot builder, team inbox, Mini CRM and automation already built and included in one ₹599 monthly plan, at Meta's rate with no markup. If you have a development team and want to build something fully custom, Twilio is a legitimate starting point. If you want your team messaging customers on WhatsApp this week without a build project, WA.Expert already did the building.
Setup takes minutes. And if you ever get stuck, we are the only platform in India that answers you live on WhatsApp.
