Jolter ships as a native executable. The installer places the binary on your machine; jolter setup then creates command shims and prints shell-specific PATH instructions.

​
Quick install

irm https://get.jolter.dev/install.ps1 | iex

curl -fsSL https://get.jolter.dev/install.sh | sh
After installation: 
jolter --version
jolter setup
jolter doctor
One-line installers execute remote code. Security-sensitive environments should download and review the script first or install a checksum-verified release archive.

​
Inspect before running

Invoke-WebRequest https://get.jolter.dev/install.ps1 -OutFile install-jolter.ps1
Get-Content .\install-jolter.ps1
.\install-jolter.ps1

curl -fsSL https://get.jolter.dev/install.sh -o install-jolter.sh
less install-jolter.sh
sh install-jolter.sh
Use your normal endpoint-security and code-review policy before executing any downloaded installer.

Supported release targets

PlatformArchitectureRust target
Windowsx64x86_64-pc-windows-msvc
Linuxx64x86_64-unknown-linux-gnu
macOSIntel x64x86_64-apple-darwin
macOSApple Siliconaarch64-apple-darwin
WSL uses the Linux x64 build. Runtime providers can impose additional requirements, such as CPU features required by Bun artifacts.

​
Manual release archive

Download the archive and sibling .sha256 file from the matching GitHub release. Archive names follow this shape: 
jolter-v<version>-<rust-target>.tar.gz
jolter-v<version>-x86_64-pc-windows-msvc.zip
Verify before extraction: 
sha256sum -c jolter-v0.3.0-x86_64-unknown-linux-gnu.tar.gz.sha256

shasum -a 256 -c jolter-v0.3.0-aarch64-apple-darwin.tar.gz.sha256

$actual = (Get-FileHash .\jolter-v0.3.0-x86_64-pc-windows-msvc.zip -Algorithm SHA256).Hash.ToLowerInvariant()
$actual
Get-Content .\jolter-v0.3.0-x86_64-pc-windows-msvc.zip.sha256
Compare the values, extract the archive, and place jolter or jolter.exe in a user-controlled directory on PATH. Then run: 
jolter setup
jolter doctor
Never install an archive whose checksum does not match.

​
Build from source

Rust 1.85 or newer is required. 
git clone https://github.com/jolterjs/jolter.git
cd jolter
cargo build --release --locked
The executable is written to: 
Windows: target/release/jolter.exe
Unix:   target/release/jolter
Run the quality gates before distributing a local build: 
cargo fmt --all -- --check
cargo clippy --workspace --all-targets --locked -- -D warnings
cargo test --workspace --all-targets --locked

​
Upgrade

Run Jolter’s built in upgrade command to update Jolter itself: 
jolter upgrade
After upgrading: 
jolter --version
jolter setup
jolter doctor
Refreshing shims ensures they point to the new Jolter executable. Refreshing shims is done by the setup command.

​
Remove Jolter

Jolter provides you with uninstallers similar to the installers at the start of the page.
One-line uninstallers execute remote code. Security-sensitive environments should download and review the script first or install a checksum-verified release archive.
irm https://get.jolter.dev/uninstall.ps1 | iex

curl -fsSL https://get.jolter.dev/uninstall.sh | sh
Use your normal endpoint-security and code-review policy before executing any downloaded uninstaller. The above scripts will remove Jolter entirely from your system, however removing Jolter does not modify project jolter.json files.
