FREE PLAN • NO CARD NEEDED
Free voice call SDK: 2,000 minutes a month
RTCExpress has a free plan for developers: 1:1 voice calls with 2,000 voice minutes every month, plus in-app chat, in SDKs for Android, Flutter, React Native and the web. It isn't a trial; it renews every month for as long as you use it.
What the free plan includes
| Price | $0, no card needed |
|---|---|
| Voice | 1:1 voice calls, peer-to-peer |
| Voice minutes | 2,000 participant minutes a month (about 1,000 minutes of 1:1 calling) |
| In-app chat | Up to 100 chat users a month |
| Projects | One project |
| Support | Usage dashboard and community email support |
The honest limits
- Minutes count every person in the call. Two people on a 10-minute call use 20 participant minutes, so 2,000 minutes is about 1,000 minutes (roughly 16 hours) of 1:1 calling a month. Most voice SDK providers count minutes the same way.
- Free calls are 1:1 and peer-to-peer. Audio goes directly between the two devices, relayed through our TURN servers only when a network blocks a direct connection. Group voice calls start on Starter ($9/month).
- Video is on Pro. Video calls and screen sharing are included from $29/month.
- No surprise charges. We never bill per minute. Your console shows usage, and if a project keeps going over its allowance, we ask you to move to a larger plan instead of charging you.

When you outgrow free
Starter is $9/month for 30,000 voice minutes and group calls; Pro is $29/month and adds 10,000 video minutes and screen sharing. Both are flat prices, so your bill doesn't grow with every call. Compare plans on the pricing page.
