playSMS is free, open-source SMS management software with a web interface for gateways and bulk SMS services. It sends individual or bulk text, flash, and Unicode messages, and receives private SMS that can be forwarded to email or mobile phones or routed to users and URLs. Built-in tools include automatic replies, polls, quizzes, subscriptions, SMS-to-email, and email-to-SMS through mailbox polling. It connects with Gammu, Kannel, SMS Server Tools, Jasmin, Playnet, Uplink, and several SMS providers. Web services support sending, delivery reports, credit checks, and other operations. Plugins can add features, themes, tools, and gateway modules. Routing can use prefixes or users, with destination-based rating and per-user credits. The project reports one user tested 200,000 SMS per day. playSMS itself cannot send or receive messages without a separate gateway application or service. It is available for Android, Linux, self-hosting, web, and API use under GPLv3 or later, without warranty.
