Free to download. thread0 does not resell tokens or add a model markup — your provider subscriptions, charges, terms and limits stay exactly as they are.

Installers are code-signed for Windows (MAI DEPOT, Inc) and notarized by Apple. Windows shows a warning? Here is what to do →

Windows · first days after each release

Windows will warn you twice. Both are expected.

Every new release needs a few days to build download reputation with Microsoft, so Windows warns even though the file is signed. The signature — not the absence of a warning — is what tells you the file is genuine. Check that the publisher reads MAI DEPOT, Inc and continue.

  1. 1

    Your browser asks whether to keep the file

    thread0 Setup.exe isn’t commonly downloaded
    Discard Keep
    Chrome and Edge downloads panel

    Open the downloads panel with Ctrl+J, click the ⋯ menu next to the file and choose Keep. Edge may add one more step: Show more → Keep anyway.

  2. 2

    SmartScreen shows a blue screen when you run it

    Windows protected your PC
    Microsoft Defender SmartScreen prevented an unrecognized app from starting.
    More info
    Publisher: MAI DEPOT, Inc
    Run anyway Don’t run
    Microsoft Defender SmartScreen

    Click More info. A Publisher line appears — it must read MAI DEPOT, Inc. Then click Run anyway. If the publisher shows anything else, close the window and download only from this page.

  3. 3

    Optional: verify the signature yourself

    Right-click the installer → Properties → Digital Signatures and confirm the signer is MAI DEPOT, Inc. You can also compare the published SHA-512 checksum.

Why does this happen at all?

SmartScreen combines the code signature with how widely a file has been downloaded. A brand-new installer has no download history yet, so it is treated as unrecognized until enough people have run it. The warnings stop on their own as that history builds.

Windows · x64

Windows 10 and 11 on x64. The installer is Authenticode-signed by MAI DEPOT, Inc.

macOS · Apple silicon

thread0 for macOS

Apple silicon Macs, delivered as a DMG. Open the image and drag thread0 to Applications. The app is Developer ID signed and notarized by Apple, so it opens without security warnings.

What you need

Windows 10 or 11 on x64, or macOS 13+ on Apple silicon. The installers manage their own runtime and optional command-line dependencies — no Node.js or npm required.

Bring a personal provider account, an organization-assigned seat or an approved enterprise route. Everyone signs in directly on their own computer; thread0 provides the workspace, session control, mobile pairing and local security boundaries.
