Modelist alternatives for local STL libraries
By Petros, who builds Meshory · Updated Oct 11, 2026 · 8 min read
Modelist is a local-first desktop app for macOS, Windows and Linux that indexes your existing folders. Most people searching for an alternative have hit one specific wall: the 100-file free tier, tags lost on a drive move, no live folder watching, or companion files it cannot show. This page names each one and shows how Meshory fixes it.
The limits below are the ones that send people looking, and each is documented by Modelist itself rather than inferred from a review.
The four reasons people switch
- 1The free tier is a trial. A hundred files is enough to decide whether you like the idea and nowhere near enough to hold a library. Anyone who arrived through the free tier hits this wall in an afternoon, and it is the most common reason the search happens at all.
- 2Moving files between drives loses your work. Modelist's own documentation notes that a cross-drive move reads as a delete plus a re-add, so tags, notes and metadata do not survive it. Same-drive moves are safe. If you are consolidating onto a new drive or a NAS, this is the one that hurts.
- 3Folders are not watched live. Modelist syncs at launch and checks for new files as you use it, but deliberately avoids live filesystem watchers. If files arrive throughout the day, the library falls behind until the next check.
- 4Loose companion files are not covered. Modelist shows custom thumbnails, images pulled from a model's source page, and the assembly guides packed inside a 3MF, but documents no way to attach other photos or documents. If your bundles arrive with creator renders and PDF instructions as separate files next to the model, that content stays out of view.
What you gain by switching to Meshory
- No file cap: one $34.99 license covers the whole library, with every v1 update included, and a free trial lets you run it on your real folders first.
- Tags that survive a drive move: models are tracked by content fingerprint, so your tags, notes and thumbnails follow a file to a new drive or a NAS.
- Folders watched in place: local folders get a live file watcher and network shares refresh on a schedule you set, every 30 seconds by default, so new downloads show up without waiting for the next launch.
- Duplicates found by geometry: re-exports and format conversions that keep the model in place group with their originals, and whole duplicate folders are flagged together.
- Companion files beside the model: the creator photos (HEIC included), PDFs, readmes and Markdown notes that ship in a bundle sit next to the model they belong to, and so do videos once you switch on video indexing.
- STEP, FBX, GLB and PLY in the viewer: STL, 3MF, OBJ, FBX, GLB, PLY, STEP, Rhino 3DM and Fusion F3D/F3Z all get thumbnails and open in the 3D viewer, and Lychee LYS scenes do too in an experimental preview. Modelist's feature list names STL, OBJ and 3MF for its preview and indexes STEP for search.
- AI tagging and semantic search: optional, through your own OpenRouter, OpenAI, Anthropic or Gemini key, Codex CLI on a ChatGPT plan, or a local Ollama model. With OpenRouter, semantic search finds a model by describing it. Modelist has no AI features.
- Built for NAS scale: Meshory was tuned against a 118,270-model, 3.5TB NAS library before it shipped.
If you left over the drive-move problem
Modelist ties metadata to a file's location, which is why crossing a drive boundary breaks the link. Meshory tracks models by content fingerprint instead, so tags, notes and thumbnails follow a file through renames, reorganizing and a move to a new drive. The free trial is the quickest proof: tag a handful of files, move them to another drive, and watch the tags arrive with them.
If you left over duplicates at scale
Modelist's three methods are exact, name-plus-size, and perceptual matching. None of the three compares the mesh itself, so a model re-exported by its creator or converted between formats shares no bytes, no name and no size, and slips through. Meshory fingerprints the geometry, which closes that gap: a re-export or conversion that keeps the model in place is called Identical geometry, and a slicer project that re-centers the model lands in a review queue as a likely duplicate. How hash and geometry detection differ explains which tier catches what.
Modelist alternatives compared
Four more tools come up in the same searches. Each row below comes from that tool's own site, help pages and release notes, checked in September 2026.
| Tool | Duplicates matched by | Tags after a drive move | AI tagging | Runs on |
|---|---|---|---|---|
| Meshory | File content and mesh geometry | Kept, tracked by content fingerprint | Optional, on your own key, with semantic search | macOS, Windows, Linux |
| Modelist | Exact bytes, name and size, similar previews | Lost, per its own help docs | None | macOS, Windows, Linux |
| Competitor 1 | Exact bytes only | Not documented | Tag suggestions only | macOS, Windows, Linux, Docker |
| Competitor 2 | Exact bytes only | Not documented | Through an external AI assistant | macOS, Windows, Linux, Android |
| Competitor 3 | None | Saved in files beside the models | None | macOS, Windows, Linux |
| Competitor 4 | Exact bytes only | Not documented | None | A server you host (Docker) |
Meshory is the only one of the six that compares the mesh itself, so a re-export or format conversion that keeps the model in place is caught as the same model instead of counted as a new one. The others each carry a catch: Competitor 1's stable release previews STL and 3MF only, with other formats still in beta; Competitor 3 captures every thumbnail by hand, one model at a time, and has not shipped a release since September 2025; and Competitor 4 is a web app you run on your own server.
See your own duplicates by geometry
Point the free trial at the folders Modelist already indexes, and the first scan groups the re-exports a byte check misses.
Switching from Modelist in an afternoon
- 1Point Meshory at the same folders. Both apps index files where they already live, so nothing moves and nothing needs exporting.
- 2Let the first scan run. Every model gets a rendered thumbnail, the ones inside archives included, and duplicates are grouped by content and geometry.
- 3Rebuild your tags with bulk tagging, or let optional AI tagging suggest them. From here on they are tied to each model's content, so the next drive move keeps them.
Two things stay behind: TAR.BZ2 archives, which Meshory does not read, and Modelist's printer list. Meshory keeps printers on its Print queue, added from your slicer's presets or by hand, and ships a filament library, so you set those up again rather than importing them. The head-to-head comparison sets the two apps out feature by feature, and the feature list covers everything else Meshory does.
Modelist alternative questions
What is the best alternative to Modelist?
For a growing print library, Meshory. It indexes the same folders in place with no file cap, keeps tags attached through drive moves by tracking content fingerprints, watches local folders live, and is the only tool on this page that matches duplicates by mesh geometry. It is a one-time license with a free trial.
Why does Modelist lose my tags when I move files?
Its documentation notes that moving a file between drives reads as a delete followed by a re-add, so tags, notes and metadata do not carry across. Moves within the same drive are safe. Meshory identifies a model by a content fingerprint rather than by its path, so tags and notes carry across a drive move.
Is Modelist's free tier enough to organize a library?
No, and it is not meant to be: it stops at 100 files. A real print library runs to thousands, so the tier is a trial rather than a free product. Meshory has no file cap: one license covers the whole library, and its free trial runs on the real thing.
Does Meshory open archives like Modelist does?
Yes. Meshory reads ZIP, RAR, 7Z, TAR and TGZ in place without extracting, renders a thumbnail for every model inside, and matches duplicates inside archives against the rest of the library.
Is Meshory better than Modelist?
For a library that has outgrown the free tier, moves between drives or lives on a NAS, yes. Meshory matches duplicates by mesh geometry, shows companion photos and documents beside each model, keeps metadata through moves, watches folders, renders STEP, FBX, GLB and PLY in its viewer, and was tuned against a 118,270-model NAS library.
How hard is it to switch from Modelist?
Not hard. Both apps index files where they already live, so nothing moves and nothing needs exporting. Point Meshory at the same folders, let the first scan render thumbnails and find duplicates, then rebuild tags with bulk tagging and optional AI tagging. The free trial lets you do it on your real library before paying.
Try it against your own library first
Meshory indexes in place, so pointing it at your real folders changes nothing about how your files are stored. The first scan shows you the duplicates a byte-level check cannot see.
