glb/gltf optimizer. i got tired of spammy online compressors, so i built my own.

license node react polar

glob is a logic engine for shrinking 3d assets. i built it because 50mb glb files shouldn't exist on the web.

• mesh decimation: removes polygons using meshoptimizer. drops weight without losing silhouette.
• draco compression: google's geometry compression for minimal footprint.
• model sharing: generate persistent share links with interactive 3D previews and stats.
• texture resizing: auto-scale textures to 1k/2k/4k limits. saves vram.
• bulk processing: queue 10 files. get them back optimized.
• globber tier: 8ドル/mo via polar. 500mb limits, 48h retention, persistent vault.

1. ingest: parses buffer into document object.
2. weld: merges duplicate vertices. essential before simplification.
3. decimate: collapses edges based on target ratio.
4. quantize: reduces bit-depth of attributes.
5. compress: applies draco for final reduction.

• frontend: react, vite, tailwind, shadcn, three.js
• backend: express, node, gltf-transform
• deploy: vercel (frontend + /api)
• infra: supabase (db), cloudflare r2 (model storage), clerk (auth), polar (billing)
• note: render.yaml exists if you want a long-running api

you can run glob on your own infrastructure. it's a standard node/vite stack.

1. clone: git clone https://github.com/microck/glob.git
2. deps: npm install
3. env: rename .env.example to .env and fill in the blanks.
4. run: npm run dev and npm run api:dev

you'll need accounts for:

• supabase: database. run migrations in api/supabase.
• clerk: auth. create an app and get keys.
• cloudflare r2: object storage. create a bucket.
• polar: payments. strictly optional if you strip the billing code.

o'saasy license. use it for internal tools or personal projects. don't use this code to launch a competing 3d optimization service.
