LFortran is a modern open-source (BSD licensed) interactive Fortran compiler built on top of LLVM. It can execute user’s code interactively to allow exploratory work (much like Python, MATLAB or Julia) as well as compile to binaries with the goal to run user’s code on modern architectures such as multi-core CPUs and GPUs.
LFortran is in development (alpha stage), we have released a Minimum Viable Product (MVP) version at the end of the summer 2021, see the MVP announcement for more information.

LFortran can be used as a Jupyter kernel, allowing Python/Julia-style rapid prototyping and an exploratory workflow (conda install jupyter lfortran). It can also be used from the command-line with an interactive prompt (REPL).
