Flyoobe is a Windows setup companion from Belim, the developer behind the builtbybel GitHub project. Its current generation brings Windows configuration, app choices, repeatable recipes and an upgrade path into one application. It is relevant to deliberate PC setup; it should not be treated as a universal repair tool or a guarantee that an unsupported Windows installation will receive full support.
Current download and compatibility
The stable release checked on 2 October 2026 is 3.03.100, published on 28 September 2026. The documentation covers Windows setup and Windows 10-to-11 upgrade scenarios. The inspected executable contains a .NETFramework,Version=v4.8 target marker. We have not established a complete current build-and-architecture compatibility matrix or tested the application on Windows 10, Windows 11 or a managed PC.
FlyoobeApp.zip contains the main application. Actions.zip is a separate optional package of Setup Actions. These are PowerShell jobs, disabled by default according to the current README. Having the package present does not itself approve or run its actions. You can review the main application without choosing to use those optional scripts.
File evidence for release 3.03.100
We downloaded both official release assets and matched their measured SHA-256 values and exact byte counts against GitHub’s release metadata:
FlyoobeApp.zip: 696,542 bytes.Actions.zip: 12,717 bytes.
The hashes are listed in the file table above. The extracted Flyoobe.exe returned NotSigned from Windows Get-AuthenticodeSignature, with no signer certificate. This finding concerns that exact executable. Neither an unsigned status nor a matching ZIP hash is a malware verdict. The ZIP hashes do not describe a different executable, a later release or an unofficial copy.

Is Flyoobe 3.x open source and free?
The release is available to download without a listed payment. The repository contains an MIT licence for its published source, but its README says the refactored 3.x source has not yet been published; the visible source represents the previous generation. We therefore cannot establish that the current executable is auditable from the published source or that the old source licence settles all current 3.x binary terms. Check the publisher’s current licence information before redistribution or a deployment that depends on those terms.
This distinction is why the entry does not present the repository as the current application’s source code or label the whole current release simply MIT. Free availability, source availability and permission to redistribute are separate questions.
A practical decision before using it
- Write down the specific task: a post-install setup, a repeatable configuration or a Windows upgrade. Keep unrelated changes out of the same session.
- Back up important files outside the target system. Record your current Windows edition, version and key application requirements before a major setup change.
- Read each proposed configuration change and each optional action. A saved recipe is a convenience, not independent evidence that every choice suits another PC.
- For an upgrade, review hardware eligibility and Windows setup’s actual retention choice. Do not proceed on an assumption that every file and application will be kept.
- If an alert or missing prerequisite appears, record the exact file, hash and message. Do not dismiss a security warning solely because an older version once had a reported false positive.
Official sources and Windows alternatives
The publisher identifies flyoobe.com and github.com/flyoobe as unaffiliated in its README. Use the builtbybel/Flyoobe release page. This is an attribution of the publisher’s warning, not our independent analysis of those destinations. No claim about other lookalike sites is made here.
If the goal is installation media rather than configuration, compare Rufus and Microsoft’s route in the installation-tool comparison. For an older PC, read our unsupported hardware guide and Windows 10 ESU guide; temporary security updates are not full Windows support.
Editorial review: 2 October 2026 UTC. Official documentation and release assets checked; static ZIP/executable evidence only. Current 3.x source and complete binary licence terms remain unestablished. No application, upgrade, performance or recovery test was performed.
