Grail was a free extensible multi-platform web browser written in the Python programming language. The project was started in August 1995, with its first public release in November of that year.[3] The 0.3 beta contained over 27,000 lines of Python.[3] The last official release was version 0.6 in 1999.

One of the major distinguishing features of Grail was the ability to run client-side Python code, in much the same way as mainstream browsers run client-side JavaScript code.[4][5]
