- Paste the one-liner for your OS. It installs everything and puts
spacesaveron your PATH. - Run
spacesaver.
Latest: 0.0.25
macOS / Linux (sh)
curl -fsSL https://spacesaver-updates.myevent-labs.io/spacesaver/install.sh | shInstalls spacesaver into ~/.local/bin (set SPACESAVER_BIN_DIR to override) after checking the artifact against the release manifest's SHA-256. Open a new terminal, then run spacesaver.
Windows (PowerShell)
irm https://spacesaver-updates.myevent-labs.io/spacesaver/install.ps1 | iexDownloads the per-user .msi, verifies its SHA-256 and runs it. No administrator rights are needed. Open a new terminal, then run spacesaver.
Prefer to install by hand? The per-platform archive downloads and SHA256SUMS are below.
Remove and reinstall.
Confirm where spacesaver is, delete that install, confirm the command is gone, then run the same installer so you land on 0.0.25. After remove, Get-Command / command -v should not resolve the binary.

Get-Command spacesaver
irm https://spacesaver-updates.myevent-labs.io/spacesaver/install.ps1 | iexThe first line prints the installed binary path and spacesaver uninstall removes a self-install. If you used the .msi, remove Space Saver from Settings, Apps, Installed apps instead. Then re-run the Windows one-liner.

command -v spacesaver
rm -f "$HOME/.local/bin/spacesaver"
command -v spacesaver

- What it solves
- A terminal tool that reclaims disk space safely: every item is safe, review or protected, and only recognised disposable data is ever removed. Windows, macOS and Linux.
- Who it is for
- People who need to reclaim disk space without risking files they cannot replace.
- What is included
- Per-platform downloads and a PATH install one-liner, with the setup shown below.
- Supported platforms
- Windows · macOS · Linux
- Pricing and licence
- Free. No licence, account or paid tier.
- Data and privacy
- Scans stay on your machine; paths are relative by default and only metadata is shared if you opt into model analysis.
- Support
- Feedback form; there is no guaranteed response time.

Three levels, one rule
Every item is SAFE (recognised, regenerable data), REVIEW (a recognised but ambiguous location) or PROTECTED (documents, media, source, secrets, executables). PROTECTED items are never deletable through any code path.
A folder is only safe if nothing important is inside
Caches and build output are measured as a whole. If a recognised cache contains a single PDF, photo, key or archive, it is downgraded to review and the executor refuses to touch it.
Protected territories
User content (Documents, Pictures, Desktop), secret stores (.ssh, .gnupg, .aws) and version-control directories (.git, .svn) are never offered for removal, no matter how harmless they look. System locations are skipped by default and symlinks are never followed.
Dry run by default
clean only acts with --apply, and permanent deletion needs --yes. The default removal mode moves items to the operating system trash, and every guard is re-checked against the live filesystem before anything is unlinked.
A menu, not a manual
Run spacesaver with no arguments to open an interactive menu: scan with live progress (files, folders, bytes and the folder being read), insights, cleanup plans, a safe clean, questions, history, update checks and feedback. Every action is also a subcommand for scripting.
AI storage intelligence, local first
Explain a scan and plan a cleanup without sending anything off the machine. Path privacy is controlled with --privacy (relative by default) and only metadata is shared. Bring your own key into the OS credential vault to let a model analyse a scan; the answer is validated and can never delete or reclassify anything.
Stays current
spacesaver update reads the per-platform manifest from the CDN, downloads the release, verifies its SHA-256 and installs it. The one-line installers on this page never change.
Prefer to install by hand? Download the archive for your platform, verify it against SHA256SUMS, then unpack and run it yourself. The one-line installer at the top of the page does this for you.
x86_64 - .msi installerWindowsApple Silicon - .tar.gzmacOSIntel - .tar.gzmacOSx86_64 - .tar.gzLinuxARM64 - .tar.gzLinux
Once downloaded, unpack the archive and run spacesaver from your terminal. On Windows, unzip the .zip and run spacesaver.exe, or add it to your PATH. Builds are not code-signed, so Windows SmartScreen and macOS Gatekeeper may ask you to confirm the first launch.
How do I install and run it?
Open your terminal and paste the one-line install script for your system: on macOS or Linux run "curl -fsSL https://spacesaver-updates.myevent-labs.io/spacesaver/install.sh | sh", and on Windows PowerShell run "irm https://spacesaver-updates.myevent-labs.io/spacesaver/install.ps1 | iex". Both verify the download against the release manifest's SHA-256 and put spacesaver on your PATH, so you then just type spacesaver to open the menu. Prefer to install by hand? Download the .msi on Windows or the .tar.gz for your platform from the downloads on this page, or run "spacesaver install" from the extracted binary.
Will it ever delete something important?
The design assumes the scanner will occasionally be wrong, so every layer re-checks the one below it. Only items classified SAFE are offered for bulk cleaning; PROTECTED items are never deletable, and a cache that contains an important file is downgraded and refused. Deletion re-checks the level and every guard against the live filesystem, a path that changed since the scan or sits outside the authorised folder is refused, and the default removal mode moves items to the operating system trash rather than deleting them outright.
What does the AI analysis send?
Only metadata, and how much path detail is included is your choice: --privacy full, home-redacted, relative (the default) or anonymous. Only anonymous is considered safe for a remote provider. The AI layer never classifies files, never deletes and never overrides the safety engine; its output is validated before it is shown. Keys are stored in the operating system credential vault (Windows Credential Manager, macOS Keychain, Freedesktop Secret Service), never in a file.
How do I update it?
Run "spacesaver update". It reads the per-platform manifest for the newest build from the CDN, downloads the artifact, verifies its SHA-256 and installs it (the .msi installer on Windows, an in-place binary swap on macOS and Linux). The install one-liners on this page are unchanged - they still install spacesaver and put it on your PATH.
How do I remove and reinstall it?
Run "spacesaver uninstall" to remove a binary installed with "spacesaver install", or on macOS and Linux remove ~/.local/bin/spacesaver (the install.sh location; SPACESAVER_BIN_DIR overrides). On Windows, a .msi install is removed from Settings, Apps, Installed apps. Then re-run the one-liner for your system. Run "spacesaver doctor" to see which build is running and where it lives if an old copy is still first on your PATH.
What does it cost?
The download is free, with no licence key and nothing to buy. Space Saver is proprietary software under the MyEvent Labs licence: install and run it for your own personal or internal business use. The source repository is private, but you do not need it to download and run the tool.
