Here we'll show you how to install the
wasmtime command line tool. Note that
this is distinct from embedding the Wasmtime project into another, for that
you'll want to consult the embedding documentation.
The easiest way to install the
wasmtime CLI tool is through our installation
script. Linux and macOS users can execute the following:
$ curl https://wasmtime.dev/install.sh -sSf | bash
This will download a precompiled version of
wasmtime and place it in
$HOME/.wasmtime, and update your shell configuration to place the right
Windows users will want to visit our releases page and can download
the MSI installer (
wasmtime-dev-x86_64-windows.msi for example) and use that
You can confirm your installation works by executing:
$ wasmtime -V wasmtime 0.12.0
And now you're off to the races! Be sure to check out the various CLI options as well.
Download Precompiled Binaries
If you'd prefer to not use an installation script, or you're perhaps
orchestrating something in CI, you can also download one of our precompiled
wasmtime. We have two channels of releases right now for
- Each tagged release will have a full set of release artifacts on the GitHub releases page.
devrelease is also continuously updated with the latest build of the
mainbranch. If you want the latest-and-greatest and don't mind a bit of instability, this is the release for you.
When downloading binaries you'll likely want one of the following archives (for
- Linux users - [
- macOS users - [
- Windows users - [
Each of these archives has a
wasmtime binary placed inside which can be
executed normally as the CLI would.
Compiling from Source
If you'd prefer to compile the
wasmtime CLI from source, you'll want to
consult the contributing documentation for building.
Be sure to use a
--release build if you're curious to do benchmarking!
