Sendbird vs Textline
Sendbird pricing in 2026 is MAU-based (priced by Monthly Active Users, not agent seats), starting at $349/month on annual billing ($399 month-to-month) for the Starter plan covering up to 5,000 MAU on the Chat API (sendbird.com, 2026).

It is not a help desk or shared support inbox. Pro is $499/month annual for the same 5K MAU but unlocks message translation, data export, image moderation, and supergroup channels. Enterprise is custom pricing for 100K+ MAU, with deal sizes commonly landing between $40K and $150K ARR per Vendr's 2026 marketplace data. The Developer plan is free forever for up to 100 MAU as long as you log into the dashboard at least once per year (sendbird.com, 2026).
Textline pricing in 2026 starts at $59.97/month for Essentials (3 agents, 600 message credits, 1 phone number) and $99.97/month for Pro (5 agents, 2,000 credits, 2 numbers). Extra agents cost $50–$70/month, add-on message credits $0.03 each, and 10DLC numbers carry a $15/month campaign fee (textline.com, 2026). Best suited for US small businesses that run customer communication primarily over SMS.
