 # Comparison to Similar Packages
 
 Since the release of `orbitize!` version 1, other open source packages have been released that have

+similar goals to `orbitize!`, notably `orvara` [@orvara] and `octofitter` [@Thompson:2023]. This is a wonderful development, as all packages benefit from open sharing of knowledge! `orbitize!`, `orvara`, and `octofitter` can 
 do many similar things, but each has unique features and strengths; as an example, `octofitter` is 
 extraordinarily fast, and enables joint astrometry extraction and orbit modeling, while `orbitize!` has unique 
 abilities to fit arbitrary absolute astrometry (i.e. not from Hipparcos or Gaia) and model data using an N-body backend.
