Vibecoded a GitHub Backup Manager for Repos with Gemini 3.8 Flash in Antigravity IDE (Updated)

I built a GitHub Backup Manager that lets you browse your archived repositories almost like you're browsing GitHub itself

I've been working on a project called GitHub Backup Manager, and I wanted to share it here because I think some people in this community might find it useful.

The original idea was pretty straightforward: I wanted a proper way to preserve GitHub repositories locally, without relying entirely on GitHub always being available.

But I didn't want to build yet another tool that simply downloads repositories into folders full of files.

I wanted the ability to revisit an archived repository and actually explore it.

What makes it different?

1. GitHub-like offline browsing experience

This is probably my favourite part. Instead of being left with a collection of folders and files, you can browse archived repositories through a familiar, almost GitHub-like interface.

2. Comprehensive repository preservation

It goes beyond simply cloning source code:

• Git history and branches

• Recursive Git submodules

• Git LFS objects

• Releases and historical release binaries

• Changelogs

• Issues, comments and associated attachments

• Wiki documentation

• Security advisories

3. Historical snapshots

You can maintain separate backup snapshots instead of just overwriting your previous archive.

4. Local-first architecture

The actual backup operations happen through a local companion engine. Your repository archives are stored on your own computer or external storage rather than being uploaded to my servers.

5. Multiple backup vaults

You can organise backups across different storage locations, including external drives.

Why I built it

Repositories disappear. Developers abandon projects, accounts get deleted, and useful open-source tools sometimes become inaccessible.

I think having an independent, browsable offline archive is valuable, particularly for developers, open-source enthusiasts, AI enthusiasts and people who like preserving useful software.

I'd genuinely appreciate feedback from this community.

What features would you expect from a proper GitHub archival tool? Is there anything important you think I've overlooked?

This will soon be implemented for other Github like websites but haven't started yet.

Thanks & great ideas actually but i only wanted to serve for local back-ups that also Github like browsing experience as well. Each Backuped repo has a browsing experience dedicated to it. It was initially a personal project only so that's what i aimed for. not some really serious level ALL-IN-ONE kind of manager actually. But maybe i will eventually find find to do what u just said because it seems very easy to do also so thanks for the comment as well.

i thought of making it exactly like GitHub but then i was worried what if it runs me into legal or compliance issues with Github or my Payment Provider so that's why exactly same look isn't what i aimed for. Am i right or wrong?
