Our verdict

  • Highest scoreCython · 8.7/10
  • Free planonly Cython

Cython scores higher on our rubric for code transpilers: 8.7 against 8.4 out of 10; our editors rank them #4 and #7.

Cython is the better fit for python projects needing C or C++ extensions. ClojureScript is the better fit for clojure teams targeting browser and Node.js.

Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Translates Python and Cython source into C or C++ code
  • Supports optional static types and C/C++ interoperability
  • Works with Jupyter and build tools including setuptools and Meson
  • Compiles Clojure to JavaScript with Google Closure-compatible output and optimization.
  • Supports browser, Node.js, Web Worker, and bundle targets.
  • Includes browser and Node.js REPLs, npm dependencies, macros, and source maps.
Cons
  • Requires a native build step to create importable extension modules
  • Focused on Python-to-C/C++ compilation rather than general-purpose conversion
  • Community and documentation are the listed support channels
  • The toolchain is centered on Clojure rather than multiple source languages.
  • Its feature set may be more than needed for projects that only require JavaScript.
  • Support channels are documentation and community.
