What is tpush?

Tpush is a lightweight server designed to send messages or notifications to large numbers of connected users simultaneously. Think of it like a notification hub, if you have an app or service that needs to alert thousands of users at once (say, a stock price update hitting all traders, or a chat server broadcasting a message to everyone in a room), tpush efficiently handles those outbound messages. The server is built for speed and to handle lots of concurrent connections. It's written in C++ and uses libev, a low-level networking library optimized for handling many simultaneous users without consuming excessive resources. The project also depends on tnet, another library by the same author that provides the core networking infrastructure. If you're building something that needs to push real-time updates to many clients at once, this is a minimal, purpose-built tool for that job. You'd use tpush if you're running an application that requires broadcasting notifications, think live sports scores, real-time dashboards, multiplayer game events, or instant messaging systems. It sits on a server and accepts messages, then distributes them to all the connected clients listening for updates. The README is quite sparse on details about the API or how to actually use it, so you'd need to dig into the code or contact the author to understand the exact interface. Building it requires downloading and compiling the source code locally using standard C++ build tools. The project offers a performance-oriented build option using tcmalloc (a specialized memory allocator) if you're running in production and want to optimize memory usage under load. This is a fairly minimal project, just 5 stars suggests it's either very specialized or relatively early-stage, but it could be a good fit if you need a simple, no-frills push notification server without the overhead of larger systems.
