How it works

From config to installer in one command.

install.toml

Define your app info, files, shortcuts, registry keys, and post-install hooks in a readable config.

Packager

CLI or GUI packager compresses your files with zstd level 19 and embeds them with the runtime stub.

setup.exe

A single self-contained binary. Runs the full install wizard — UI, file extraction, registry, PATH, hooks.

Features

Everything you need.
Nothing you don't.

Single-file output

One setup.exe with everything embedded — runtime, manifest, and compressed payload.

Modern dark UI

Slint-powered wizard: Welcome → License → Install → Finish. Cold-starts in under 200 ms.

zstd level 19 compression

Maximum compression with streaming packager — low peak RAM, not held in memory.

Rollback on failure

Files, shortcuts, registry, and PATH changes are fully rolled back if installation fails.

Silent & unattended

Use --silent for CI/CD pipelines, --uninstall for clean removal.

In-place upgrades

Safe reinstall over an existing managed install — auto-cleans old files.

Visual packager GUI

Slint-based builder with 8 screens — no command line required for simple builds.

Dual stubs

Normal and requireAdministrator variants — packager picks automatically based on config.

CI-ready

GitHub Actions: fmt, clippy, Linux + Windows builds, auto-release on git tag push.

Configuration

Readable config, no scripting.

A single install.toml drives everything — app metadata, files, shortcuts, registry keys, post-install hooks, and UI branding.

App info & version
File globs with exclusion patterns
Registry write (HKCU/HKLM)
Desktop shortcuts
Post-install & finish hooks
UI theme & accent color
PATH mutation

CLI

[app]
name        = "My App"

[install]
default_dir             = "{ProgramFiles}\\My App"
add_to_path             = true
create_desktop_shortcut = true

[ui]
theme        = "dark"
accent_color = "#7c3aed"
license_file = "LICENSE.txt"

[[files]]
src     = "bin/**/*"
dest    = "{install_dir}"
exclude = ["*.pdb", "*.log"]

[[shortcuts]]
name   = "My App"
target = "{install_dir}\\myapp.exe"

[[run]]
cmd  = "{install_dir}\\myapp.exe"
when = "finish"
