Meshory vs Printventory
Printventory is free and open source; Meshory is a $34.99 one-time license. An honest, sourced comparison of formats, speed at scale, AI tagging and duplicate detection, updated July 2026.
Printventory is a free, open-source (MIT) desktop app by the solo developer TechJeeper, built on Electron with a SQLite metadata database. It scans your STL and 3MF files in place, generates thumbnails automatically, finds duplicates by content hash, and offers AI tag suggestions through cloud services. A Docker image adds a server mode with a browser UI for NAS setups.
It is probably the closest thing to Meshory available for free: same in-place scanning philosophy, with content hashing at the core of both duplicate finders (Meshory layers geometry-aware matching on top). The differences that matter are format coverage, performance at library scale, how AI is wired up, and who stands behind it.

The short version.
| Feature | Meshory | Printventory |
|---|---|---|
| Platforms | macOS, Windows, Linux | Windows, macOS (unsigned), Linux beta, plus a Docker server |
| Price | $34.99 one-time (early access) | Free: open source, donation-funded |
| Scans files in place | Yes: watches your folders; files are never moved or uploaded | Yes: files stay put; metadata in a local database |
| Thumbnails | Automatic: a background worker pool renders STL, 3MF, OBJ and FBX | Automatic, cached |
| 3D viewer | STL, 3MF, OBJ, FBX, including multi-plate Bambu 3MF projects | STL and 3MF only; no OBJ or STEP |
| ZIP / archive handling | Browse inside ZIP, RAR and 7Z archives and preview models without extracting | ZIP search in beta |
| Bundled photos & PDFs | Photos viewed inline, PDFs in an embedded viewer, inside archives too | Cycles custom & 3MF-embedded images; documents outside its STL/3MF scope |
| Collections & favorites | Collections, tags & favorites on top of your folders | None; organizes with tags, designer & print-status fields |
| Per-model notes | Free-text notes on every model | Yes: custom notes on any model |
| Duplicate finder | Exact + geometry-aware matching (archives and NAS included), plus a review queue for near-copies | Content-hash DeDup with side-by-side thumbnails |
| AI tagging & search | AI tagging + semantic search with your own OpenRouter key | Cloud AI tagging via Puter, Gemini or OpenAI, tags only |
| Slicer hand-off | 15+ slicers auto-detected, one click from library to slicer | OS-level “Open with slicer” |
| Print & filament tracking | Filament library (brand, material, color) assignable per model; spool & printer tracking on the roadmap | Print status (printed / planned / in progress); no filament inventory |
| NAS / network drives | Indexed, browsable & duplicate-scanned; hashing runs in short background batches | Via Docker server mode (UNC paths, marked experimental) |
| Account required | No account: a license key, nothing else | None (free AI tier needs a Puter signup) |
| Open source | No | Yes (MIT) |
| Maturity | Early access; indexes a 3.3 TB, 39,000-model library in just under a minute | v2.1.0; own FAQ notes 1–5 min first load at 10k+ models |
The differences that matter.
Formats: STL + 3MF versus STL + 3MF + OBJ + STEP + FBX
Printventory supports STL and 3MF; its own FAQ lists OBJ as unsupported and STEP and G-code as “planned for future releases,” with ZIP searching in beta and a 50 MB default per-file cap. Meshory indexes and fingerprints STL, 3MF, OBJ, STEP and FBX, views STL/3MF/OBJ/FBX (including multi-plate Bambu 3MF projects plate by plate), and treats ZIP, RAR and 7Z archives as browsable folders.
Scale: both scan big libraries, one stays fast
Printventory's community has scanned 44,000-model libraries, but its own FAQ says a 10,000+ collection can take 1–5 minutes on first load, with lazy loading still listed as future work. Meshory was performance-hardened against a 3.3 TB, 39,000-model library before launch: indexing that library (local and network drives together) takes just under a minute, and thumbnails render in a background worker pool so the library stays usable while a scan runs.
AI: cloud services versus your own key
Printventory's AI tagging sends model metadata to Puter, Gemini or OpenAI and returns tags; the free Puter route needs a Puter account and Gemini's free tier is rate-limited. Meshory uses your own OpenRouter API key to generate both tags and a searchable description per model, which is what makes semantic search (“steampunk dragon bust”) possible, and nothing is sent anywhere unless you turn the feature on.
A hobby project versus a supported product
Printventory is a passion project: free, open source, and genuinely community-minded, with an active beta channel. It's also maintained by one person, distributes builds outside GitHub releases, and ships an unsigned macOS app that requires a Gatekeeper override. Meshory is a paid product with signed, notarized macOS builds. That's the trade a one-time $34.99 license buys.
Choose Printventory if…
- You want completely free and open source (MIT), with donations optional
- You want a Docker server on your NAS with a browser UI on any device
- Your library is STL/3MF-only and modest enough that load times don't sting
- Print-status tracking and designer metadata matter to you today
Choose Meshory if…
- You have OBJ or STEP files too, or ZIP, RAR and 7Z archives you'd rather not extract
- Your library is big enough that 1–5 minute load times would hurt daily
- You organize with collections and favorites; Printventory has tags and status fields only
- You want signed, notarized builds on macOS instead of a Gatekeeper override
- You want AI descriptions and semantic search, not only tag suggestions
Meshory vs Printventory: common questions
Is Printventory really free?
Yes, Printventory is free and MIT-licensed open source, funded by donations (PayPal, Patreon, Buy Me a Coffee). There is no paid tier. Meshory is a $34.99 one-time early-access license, with no subscription in either case.
Which formats does each app support?
Printventory handles STL and 3MF, with ZIP search in beta; OBJ isn't supported and STEP/G-code are listed as planned (as of July 2026). Meshory indexes STL, 3MF, OBJ, STEP and FBX, and browses inside ZIP, RAR and 7Z archives without extracting them.
Do both find duplicate files?
Yes, both use content hashing, so renamed copies group together. Printventory shows duplicates in a DeDup view with thumbnail comparison. Meshory goes further: exact matching reaches inside archives and across NAS sources, a geometry tier groups the same mesh saved as different files, and rotated or rescaled near-copies land in a separate review queue. Nothing is ever deleted for you.
Which is better for a NAS?
Different approaches: Printventory offers a Docker server mode you run on the NAS and reach by browser (its FAQ marks network paths experimental). Meshory is a desktop app that indexes NAS mounts alongside local folders: network sources are browsable right away, and duplicate hashing runs in short background batches so scans stay fast.
