Sendbird vs TalkJS pricing by monthly active users
TalkJS pricing is transparent and predictable, and the gap with Sendbird grows as you add users. Here’s each one’s cheapest plan at the user counts Sendbird publishes, in USD per month, billed annually.
| Monthly active users | ||
|---|---|---|
| 10,000 MAU | Basic $239 | Starter $429 |
| 25,000 MAU | Growth $499 | Starter $1,119 |
| 50,000 MAU | Growth $1,249 | Custom pricing (Starter) |
Prices are in USD per month, billed annually, as of October 2026. At 50,000 MAU, the TalkJS price is the Growth plan plus overage for each MAU over the 25,000 it includes: $499 + 25,000 × $0.03 overage = $1,249. See the current prices on the TalkJS pricing page and the Sendbird pricing page.
What Sendbird’s price leaves out
- Message history: Sendbird keeps messages for six months on every plan below Enterprise. TalkJS keeps your full message history on every plan.
- Concurrent connections: on Starter and Pro, Sendbird caps them at 5% of your MAU tier and counts each device, including an open browser tab. TalkJS has no hard limit, and fair use is about 10% of your monthly active users.
- Going over your tier: Sendbird charges an overage fee and doesn’t publish the rate. TalkJS charges $0.04 for each extra user on Basic and $0.03 on Growth, so 1,000 extra users cost $40 or $30.
