Sparrow is a state-of-the-art static analyzer that aims to verify the absence of fatal bugs in C source. Sparrow is designed by Abstract Interpretation and the analysis is sound in design. Sparrow adopts a number of well-founded static analysis techniques for scalability, precision, and user convenience: Sparrow's design and engineering efforts used have been published in the following papers.



Sparrow's performance (both in precision and scalability) is being actively improved. Thanks to our general sparse analysis framework, the current Sparrow is 175x more scalable in terms of lines of code and is 1500x faster than the initial version.
