We are Cesanta, a software engineering company based in Dublin, Republic of Ireland. Our area of expertise is embedded software focused around connected products and the Internet of Things. Most of our sofware is open source:

  • Mongoose OS - an operating system for low-power microcontrollers
  • Mongoose Web Server - an embedded web server and networking library
  • mJS - an embedded JavaScript engine for C/C++ applications
  • Frozen - a low footprint JSON parser and emitter for C/C++

As well as developing open source software, we provide professional services. We have hundreds of paying customers. With many of them, we are engaged on custom development projects.
