## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="What license types are used by FalkorDB's third-party dependencies?">
    FalkorDB's dependencies use a mix of permissive open-source licenses: **Apache 2.0** (GraphBLAS, libcypher-parser, CRoaring), **MIT** (utf8proc, C Thread Pool, MT19937-64), and **BSD 2-Clause** (xxHash, rax, sds, oniguruma).
  </Accordion>

  <Accordion title="What is GraphBLAS used for in FalkorDB?">
    GraphBLAS provides the sparse matrix operations that power FalkorDB's graph traversal engine. It implements a standard API for linear algebra operations on sparse matrices, enabling efficient graph queries through matrix multiplication.
  </Accordion>

  <Accordion title="Does FalkorDB's use of these libraries affect my project's licensing?">
    FalkorDB itself is licensed under **SSPLv1**. The third-party libraries have their own permissive licenses (Apache, MIT, BSD) which are compatible. Your obligations are governed by FalkorDB's SSPLv1 license terms, not by the individual dependency licenses.
  </Accordion>

  <Accordion title="What is the relationship between FalkorDB and RedisGraph?">
    FalkorDB originated from the RedisGraph project. RedisGraph is listed as a dependency under RSALv2/SSPLv1/AGPLv3 licensing. FalkorDB builds upon and extends the original RedisGraph codebase.
