Sendbird vs Trengo
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). Sendbird is a chat API and SDK platform — developers embed its iOS, Android, React Native, Flutter, JavaScript, and Unity SDKs to build messaging inside their own product. 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).
