Windows download & security notice

Orbit is independently developed and released as an open-source project, with an emphasis on software security and transparency. Its source code is available for review. Please obtain the software through the official project page.

Orbit has not yet obtained a code-signing certificate, and its current Windows executable is unsigned. Some users have reported that Microsoft Smart App Control blocks it.

You can decide whether to turn this protection off. Doing so reduces protection against untrusted applications; first confirm that your download comes from the official release page.

Windows Security → App & browser control → Smart App Control → Off.

After successfully starting Orbit once, you can turn Smart App Control back on to continue protecting your computer. Based on reported usage experience, Orbit generally is not blocked again after its first successful launch; Windows determines whether each launch is allowed.

You can also download the source code, review it and build Orbit yourself. A self-built unsigned application may still be blocked.
