F*: An ML-like language aimed at program verification

Build status

F* website

More information on F* can be found at




The F* tutorial provides a first taste of verified programming in F*, explaining things by example.


The F* wiki contains additional, usually more in-depth, technical documentation on F*.

Editing F* code

You can edit F* code using your favourite text editor, but Emacs, Atom, and Vim have extensions that add special support for F*, including syntax highlighting and interactive development. More details on editor support on the F* wiki.

Executing F* code

By default F* only verifies the input code, it does not compile or execute it. To execute F* code one needs to translate it to either OCaml or F#, using F*'s code extraction facility---this is invoked using the command line argument --codegen OCaml or --codegen FSharp. More details on executing F* code on the F* wiki.

Community mailing list

The fstar-club mailing list is dedicated to F* users. Here is where all F* announcements are made to the general public (e.g. for releases, new papers, etc) and where users can ask questions, ask for help, discuss, provide feedback, announce jobs requiring at least 10 years of F* experience, etc.

List archives are public and searchable, but only members can post. Join here!

Reporting issues

Please report issues using the F* issue tracker on GitHub. Before filing please use search to make sure the issue doesn't already exist. We don't maintain old releases, so if possible please use the online F* editor or directly the GitHub sources to check that your problem still exists on the master branch.


The F* for the masses blog is also expected to become an important source of information and news on the F* project.


This new variant of F* is released under the Apache 2.0 license; see LICENSE for more details.

Towards F* version 1.0

This is a new variant of F* (carrying version 0.9.x) that is still in development and we hope will eventually lead to a 1.0 release. This new variant is incompatible and quite different compared to the previously released 0.7 versions and earlier.

Old F* versions (v0.7.1 and earlier)

F* v0.7.1 and earlier are no longer maintained, so please do not create any issues here about those versions.
