Now the Asset Scanner is a bit better, you can now use the metadata of the files to look for the origin in Booth, other stores will be added in following releases

Added

• Added the BOOTH Origin Finder with local metadata analysis, background rate-limited searches, candidate review tools, high-confidence selection, and per-item search.
• Added recursive compressed-file scanning for nested Unity packages and full Unity Assets/... pathname display.
• Added sanitized public showcase snapshot creation and publishing controls.

Changed

• The scanner remembers its selected folder and removes successfully imported results.
• Downloaded updates now offer immediate or deferred installation, and Settings shows the installed version.

Fixed

• Later scanner imports for the same BOOTH item now use one asset folder.
• Individual origin searches keep the current result in view.
• Dependency references no longer count as exact origin matches.

I'm glad to announce BBLM is a lot more useful now

Version 1.4.0 now includes:

• Optional Malware check ( Thanks to @summertyt for allowing me to include vrchat-scanner in BBLM)
• Import Assets directly into unity (requires importing the companion .unitypackage to your project first)
• Easier Autoupdates to BBLM
• A NSFW Assets filter

v1.4.0 update notes:

Added

• Malware scanning — imported .unitypackage, .zip, .rar, and .7z files are scanned in the background with the vrchat-scanner CLI, which is downloaded and kept up to date automatically. Flagged assets show a warning modal with the scan output, and can be marked safe or unsafe. A Threat filter lets you browse the library by scan result. Assets already in your library are swept one at a time whenever the computer has been idle for a few minutes, and a Scan All Assets Now button in Settings runs the whole library on demand. Scanning (and the idle backlog sweep) can each be turned off in Settings.
• Unity project import — right-click any asset with an archive or .unitypackage file and choose Add to project to copy selected files straight into an open Unity project, including files nested inside archives. A companion Editor script (installed once per project via Settings → Unity Import) lets BB's LibMan detect which Unity projects are currently open and drop packages in for Unity to import automatically.
• Release notes popup — shows a summary of what changed after an auto-update, pulled straight from the changelog. Revisit it anytime from Settings → About → Show Release Notes.
• Adult content flag and filter — items marked adult by the Booth API are tagged as such; a Show All toggle in the library header hides or reveals them.

Changed

• The Library, Booth Free Items, and Library Scanner tabs now share one header bar, with search and tag/threat filters grouped together above the asset grid.

Download here if you don't already have v1.3.0

https://github.com/BunBnnuy/BBLM/releases/tag/v1.4.0

If you already had v1.3.0 It should auto update

1.3.0

I was working on some minor stuff when i noticed Booth direct downloads were not working
Booth.pm hardened the download method to now require some parameters that were previously optional. Had to release this version to fix it

Also starting from this version, the app now auto updates so no more manually coming back here ^^

The rest of the version notes:

Highlights

• Automatic updates — the app now checks GitHub Releases on launch, downloads updates silently in the background, and installs them on the next quit.
• Grid / List view toggle for the Booth Free Items tab.
• Security hardening across filesystem, network, protocol-parsing, and Electron/IPC boundaries; asset writes are now transactional with rollback on failure.

Fixed

• Booth Free Items scanning failing with Invalid IP address: undefined.
• Free item downloads being silently rejected due to unrecognized Booth deeplink query params (order_id, variation_id, client).
• Free item downloads hanging for 60s and timing out when Booth navigated to the download scheme via same-page JS instead of an HTTP redirect.

1.2.2 Fixing bugs

A bug-fix release that repairs the import pipeline — most importantly, multi-file imports no longer lose their fetched title and thumbnail.

Import Fixes

• Fetched metadata is saved on multi-file imports. Importing several files at once discarded the title and thumbnail retrieved by Fetch data — cards ended up named after the raw .zip file with no thumbnail. Tags saved correctly, which made the failure look partial and inconsistent.
• Files sharing an origin no longer overwrite each other. Because files with the same origin URL land in the same asset folder, each one re-ran the full import and rewrote meta.json, wiping the previous file's metadata and file list. They are now appended to a single asset.
• The import dialog always opens. A closed or crashed dialog could leave a stale window reference behind, after which every attempt to open it silently did nothing until the app was restarted.
• The drop overlay no longer gets stuck. Dragging a file in, hovering Add to Existing long enough to arm it, then dragging back out left the overlay on screen indefinitely. It now clears when the drag ends, with a 10-second failsafe.

Improvements

• Auto-fetch now runs for multi-file imports that arrive with a known origin URL, not just single files.
• The asset name field is visible for multi-file imports — it used to be hidden, so a fetched name could be neither seen nor corrected.

️ Behaviour Change

Multi-file imports with an origin URL now create one asset containing all the files, rather than one asset per file — the right shape for an avatar plus its texture packs. Files imported without an origin URL are still saved as separate assets, named after their filenames, exactly as before.

As for too many assets yeah BUT you don't need to rescan every time you want to work on moving your assets, the list is saved if you want to tackle it by small chunks

I was planning on making it smart by looking at the pathname package name and try to look for it in common sites like payhip/jinxxi/booth But realized it was a really bad idea when i was temporally banned from booth for API abuse lol

2.There are too many assets found after scanning to add them all at once.

What's New in v1.2.1

Booth Card Polish
Moved the Booth source badge from the bottom-right to the bottom-left of the card thumbnail
Added a hover-only open origin link button in the bottom-right corner — click it to open the item's original listing in your browser without leaving the app

Check it out at this git release:
https://github.com/BunBnnuy/BBLM/releases/tag/v1.2.1

Todo: Make an auto updater

What's New in v1.2.0

Library Scanner
A new tab for finding assets already on your disk that haven't been imported yet. Pick any folder, scan it recursively for archives and Unity packages, then import anything you find directly from the results list — no drag-drop needed.

Booth Free Items: Enable / Disable Toggle
The Booth Free Items tab now has a master on/off switch so you can disable scanning without losing your settings.

Desktop Notifications Toggle
A new toggle in Settings lets you turn download completion / failure notifications on or off.

Add Asset Button
A quick "+ Add Asset" button in the library toolbar opens the import dialog without needing to drag a file.

It would also be nice if maybe when importing you can choose to "add to existing collection" so i.e:

I download a fullset that is in multiple zips for each avatar and the materials, when it detects the download there should be a button of "add multiple to existing collection" and let me choose in explorer which ones and then in the program to where. :3

...or maybe a smart feature IF the file name of the zip has the same name as one that's already added it can be added automatically

Release v1.1.0

https://github.com/BunBnnuy/BBLM/releases/tag/v1.1.0

What's new

Booth Free Items tab

A new tab that automatically scans Booth.pm for ¥0 VRChat items.

• Smart detection — visits each item page to check all variation prices, catching partially-free items (e.g. ¥0 – ¥300) that appear paid on the listing page
• Price range display — shows the full range when an item has both free and paid tiers
• Internal download — clicking Download handles the full flow inside the app; a Booth login window appears automatically when unauthenticated, and the session is remembered
• "In Library" detection — Download button is grayed out with In Library for items you already own, updating live as downloads complete
• Paginated list — thumbnail, name, and price in a clean 20-item paginated list; click any row to open the item on Booth
• Auto-scan — configurable interval (1–24 hours) or manual trigger
• Configurable depth — set how many listing pages to scan (default 5, max 20)

Bug fixes

• Fixed thousand-separator parsing: items priced "1,000 JPY" were incorrectly detected as ¥0 free items
• Library list now refreshes automatically when a download completes (no page change needed)

Tag System

• Assets now support multiple tags
• Booth items get tags auto-populated from the BLM database and Booth JSON API
• Searchable multi-select tag filter panel with AND logic
• Tag editor with autocomplete in the import/edit dialog

Smarter Drag & Drop

• Two drop zones: Add New Asset (left) opens the import dialog, Add to Existing Asset (right) lets you hover 500ms then drop a file directly onto any card — no dialog
• Download Queue
• URL scheme downloads queue serially, one at a time
• Footer shows active progress + pending count badge, with cancel support

Two-Phase Booth Import

• Asset card appears immediately with thumbnail; file downloads in the background with a per-card progress bar

Card Glow

• Cards briefly glow when modified (imported, edited, downloaded, file added)

Pagination

• Configurable page size: 10, 30, or 50 items per page

Fixes

• Fixed double-decode bug corrupting AWS pre-signed download URLs
• Content-Type validation to reject HTML error pages saved as ZIP
• Single click → Edit modal; double click → open folder (250ms debounce)
• Progress bars moved to footer; no duplicate bars

I'll edit the post with a video of the app working

nice tool tho
