In short
- Both send SMS from your Android phones, with a REST API, signed webhooks and idempotency keys.
- SMSKit costs $5 per phone per month with unlimited messages, and routes across every phone and SIM you connect.
- DroidSender adds campaigns from Excel or CSV, automatic STOP handling and a web inbox on every plan, the free one included.
Both turn the Android phones you already own into an Android SMS gateway, so messages go out from your own SIM with no fee per message. SMSKit is built for developers who send one-time codes, alerts and two-way chats from their own code. DroidSender also gives whoever answers customers a dashboard for campaigns and replies.
