Respond.io vs WATI vs InstantReply (2026): Full Comparison
The short answer
Respond.io lists Starter at $79/mo billed annually for 5 users, with Growth ($159/mo, 10 users) and Advanced ($279/mo, 10 users) priced by Monthly Active Contact tier from 1,000 and billing $12 or $15 per extra 100 MACs above the tier (respond.io/pricing, checked October 18, 2026). WATI includes 3 users on Growth with no option to add more, 5 on Pro and Business, and charges up to $39 (Pro) or $69 (Business) per extra user per month, plus per-message charges on every plan (wati.io pricing, checked September 29, 2026). Neither is accurately called text-only anymore -- Respond.io's Growth+ AI Agents handle images, files, and audio, and WATI's Astra layer reads text, images, and audio on Pro and Business. InstantReply is $129/mo Growth with 5 seats (Pro $349/mo, unlimited seats), unlimited contacts and no per-contact fees, WhatsApp, Instagram and Messenger, and voice-note and image context on every plan.
