Software

We have a Roaring Bitmap organization on GitHub counting over 40 programmers. We maintain a portable format specification.

• RoaringBitmap is a widely used, optimized and robust Java library. It supports both regular and off-heap (e.g., memory mapped) bitmaps.
• The CRoaring library is a C/C++ library that provides an optimized implementation of Roaring for C/C++ programmers. It works under Windows (Visual Studio), Linux (ARM and x64) and macOS.
  • We have Python libraries wrapping our C code: PyRoaringBitMap and python-croaring.
  • We have a Swift library wrapping our C code.
  • We have a Rust library wrapping our C code.
  • We have a Go library wrapping our C code.
    
  • We have a Node/JavaScript library wrapping our C code.
  • We have a WebAssembly library wrapping our C code.
  • We have a D library wrapping our C code.
  • We have a Redis Module wrapping our C code.
  • We have a PostgreSQL Extension wrapping our C code.
  • We have a Greenplum Extension wrapping our C code.
  • We have a C# library wrapping our C code. It works under Windows and Linux. See also the .NET wrapper around Roaring64Map.
• We have a pure Go implementation of Roaring.
