Short answer: if respond.io's contact-based pricing or breadth is more than you need, a WhatsApp-first inbox such as Wati or Gallabox is the closest swap. European support teams who live in email should look at Trengo or Superchat. Businesses in the Gulf wanting Arabic-language tooling can look at Unifonic. Developers who would rather build than buy can use Twilio. If the gap is phone calls, ThinnestAI puts one AI agent on WhatsApp and your phone line with a shared memory.
What does respond.io do well?
Be clear on what you would give up. respond.io's site (read 24 October 2026) describes a team inbox with AI agents and CRM sync across WhatsApp, WhatsApp Business Calls, Instagram, Facebook Messenger and calls, TikTok and email, with chats, calls and emails "in one thread". Workflow automation starts on its Growth plan, and HTTP requests in workflows plus webhooks on Advanced. It is a strong choice for sales teams running ads across several social channels.
Why do teams look for an alternative?
- Pricing shape. Its pricing page shows Starter at $79, Growth at $159 and Advanced at $279 a month billed yearly ($99, $199 and $349 monthly). Growth and Advanced include 1,000 monthly active contacts, and extra contacts are billed in blocks of 100 ($12 on Growth, $15 on Advanced). A business with many one-off contacts each month can outgrow the allowance quickly.
- WhatsApp fees are separate. They are not included in any subscription; you top up WhatsApp credit on the platform.
- Broadcasts start on Growth, and the free trial excludes them.
- You only need WhatsApp, or you need a phone line answered by AI rather than more social channels.

Which alternative fits which reason for leaving?
If you only need WhatsApp: Wati or Gallabox
Wati shows an Official Meta Business Partner badge, a team inbox, Astra AI agents that "run conversations end-to-end and hand off with the full thread", and a 7-day trial; template messages are charged on top of its plans. Gallabox lists Basic, Essential and Advanced plans in rupees, dollars and dirhams, with flow limits per plan, AI agents on WhatsApp and Instagram from Essential and AI voice on Advanced.
If your support team lives in email: Trengo or Superchat
Trengo's Boost plan is €299 a month billed annually (€349 monthly) with 10 users, and Pro €499 (€599 monthly) with 20 users; each includes a conversation allowance. Superchat lists a free plan and paid plans at €89, €149 and €299 a month, with AI agents from Professional and a 12-month minimum term.
If you sell in the Gulf: Unifonic
Unifonic, which began in Saudi Arabia and lists offices in Riyadh, Dubai, Cairo, Amman and Lahore, offers an agent console where unlimited agents share one WhatsApp number, with skills-based routing and Arabic language support.
If you want to build it yourself: Twilio
Twilio's WhatsApp offering is a set of APIs: Programmable Messaging, Conversations for two-way threads, a Voice API for WhatsApp Business Calling and a Senders API. Its pricing page shows a $0.005 fee per message, inbound or outbound, with Meta's charges passed through. You build or add the inbox yourself.
If the gap is the phone: ThinnestAI
respond.io lists AI agents for voice calls; ThinnestAI's angle is one agent everywhere. The agent that answers WhatsApp also answers your business phone line, website chat and Telegram, and recognises a caller who messaged you on WhatsApp by their number. By default it says "we've spoken on WhatsApp before" but withholds what was said until the person is verified, because caller ID can be faked. Voice calls work in 50 languages; written replies in 37. It is not a fit if you need Instagram, Messenger, TikTok or email, or a visual workflow builder. Outside India, you import your own phone number from Twilio, Telnyx or Plivo for calls.
How should you compare costs fairly?
- Count a typical month: active contacts, seats, broadcasts and AI replies.
- Price each platform's subscription on that month, including add-ons and overage.
- Add Meta's charges separately. Meta charges per message, by category and by the recipient's country, and publishes the rates on its pricing page; ask each vendor whether it adds anything to them.
- Run a trial on real conversations before you move your number.
