Quasardb is fast. Very fast. It will show in benchmarks, but most importantly it will show in real-life. Not only will quasardb work faster, but it will use less memory, less CPU and less disk. The speed comes from choosing the right data structures, the right algorithms and implementing them well in high-quality, modern C++.

  • Fast in frugal: do more with less.
  • Advanced, high-performance memory and I/O management
  • High-quality, modern C++ implementation


It cannot be simpler than a key-value store. Need to add an entry? Chose a name and add your data! Need to organize your content? Tag your entries! Simplicity shows in the API but also in deployment. Running a quasardb node is a matter of running one executable and most of the configuration options are computed automatically.

  • Easy to understand concepts for immediate productivity
  • Simple API available in many languages
  • Automatic configuration for fast deployment
