3D printing enthusiasts who accumulate thousands of downloaded STL, 3MF, STEP, and OBJ archives across disorganized folders can index, preview, and catalog their entire library with Manyfold, a self-hosted digital asset manager purpose-built for additive manufacturing. Point it at an existing local directory or an S3-compatible bucket and it automatically scans nested folders, groups multi-part meshes into unified model entries, and renders interactive 3D previews right in your browser. You can organize assets by creator, collection, tag, and scale, distinguish between pre-supported and unsupported resin files, and import rich metadata directly from Thingiverse, Printables, Cults3D, and MyMiniFactory. Built-in troubleshooting tools flag duplicate meshes, manifold geometry errors, and inefficient file formats, while customizable file-naming templates reorganize messy directory trees on disk with a single click. Ready to print? Open models directly in OrcaSlicer, PrusaSlicer, or UltiMaker Cura, or transmit sliced G-code straight to OctoPrint and Moonraker printers. Multi-user access control and native ActivityPub federation let you share public collections and follow remote creators across the Fediverse.

Running out of filament mid-print ruins multi-hour 3D printing jobs, and Spoolman solves this by tracking every gram of plastic across your entire workshop in a centralized, self-hosted inventory database. Connected directly to Klipper, Moonraker, Mainsail, Fluidd, OctoPrint, and OctoEverywhere, the service deducts filament weight automatically over live WebSockets as your extruders run. You can import manufacturer specifications from the community SpoolmanDB catalog, filter your library by color similarity or material type, and organize spools on a drag-and-drop board grouped by storage location or custom fields. A built-in label designer generates printable QR code sheets containing spool metadata, while NFC and RFID tag scanning lets you tap a physical roll against an ESPHome reader or Android phone to pull up its record immediately. Multi-printer workshops can monitor concurrent consumption from several machines simultaneously, expose inventory metrics to Prometheus and Home Assistant, and query stock levels through a Model Context Protocol (MCP) server.

Over a million active instances make OctoPrint the standard web interface for consumer 3D printers - Gina Häußge's Python application, the center of the printing world since 2012. It talks to your printer over USB serial and turns every browser into a control panel: upload, organize, and start G-code prints; watch hotend and bed temperature graphs in real time; drive the print head manually; adjust feed rate, flow, and fan speed mid-print; and hit an emergency stop if things go wrong. The G-code visualizer renders the current layer in sync with the job, and a connected webcam adds a live feed plus automatic timelapse recording of every build. What keeps OctoPrint ahead is its plugin ecosystem - 300+ community plugins installable from the built-in manager. Highlights include Obico's AI spaghetti detection that pauses failed prints automatically, OctoEverywhere for tunnel-based remote access, Bed Level Visualizer's 3D mesh of your bed surface, PrintTimeGenius for accurate time estimates, Exclude Region to abandon one failed object mid-print while others continue, and Firmware Updater to flash Marlin or Klipper without SD-card shuffling. Event hooks fire notifications when prints finish or fail, and a full REST API supports slicer integration and custom automation. AGPL-licensed.

Controlling Klipper-powered 3D printers from a single browser workspace, Mainsail delivers a responsive web interface for monitoring print jobs, tuning kinematics, and managing multi-printer farms in real time. Makers and print farm operators monitor extruder and heated bed temperatures, fan speeds, and toolhead coordinates live on customizable dashboard layouts. An integrated file manager and syntax-highlighted editor let you upload G-Code directly from your slicer, organize print job queues, and modify Klipper configuration files (`printer.cfg`) without opening an SSH terminal. Interactive 3D visualizations render bed mesh heightmaps for first-layer leveling diagnostics alongside a real-time 3D G-Code toolpath viewer that tracks layer progress. Multi-webcam streaming, automated timelapse recording through `moonraker-timelapse`, Spoolman filament spool tracking, and mid-print object exclusion help salvage multi-part plates when a single model detaches. You can also organize parameterized Klipper macros, switch smart relays or Tasmota power plugs, and audit historical job success rates and filament consumption.

Command and automate your entire fleet of 3D printers without relying on proprietary cloud services using Bambuddy, a self-hosted management hub that delivers local network control, print scheduling, and job archiving for Bambu Lab hardware. Print shop operators can route slicing output directly from Bambu Studio or Orca Slicer through virtual printer proxies that emulate physical machines while automatically cataloging print files in a searchable 3D repository. The automated dispatch engine assigns queued gcode files to available printers based on required nozzle temperatures, build plate dimensions, and matched multi-color filament slots. Users can inspect live camera streams across multiple printing beds simultaneously, verify empty build plates before dispatching new jobs, and generate stabilized timelapse videos with custom music. Integrated smart plug connectors automatically cut power to idle machines when print cycles finish and trigger push notifications to Discord or mobile devices if thermal anomalies or mechanical pauses occur. Farm managers can schedule maintenance alerts based on cumulative motor runtime, track spool inventory levels across storage locations, and synchronize printing configurations across duplicate hardware setups.

Across electronics labs, hardware startups, and university makerspaces, Part-DB indexes thousands of resistors, microcontrollers, and SMD reels with datasheets, storage locations, and live supplier pricing. Each component record tracks categories, footprints, manufacturers, multi-currency order histories, electrical tolerances, and custom tags for instant parametric search. New shipments populate part attributes, product photos, and PDF datasheets directly from Octopart, DigiKey, Mouser, Farnell, LCSC, or TME, alongside AI-assisted extraction from uploaded datasheets. Print custom barcode labels on demand. Scan internal IDs, GTIN codes, or distributor DataMatrix labels with a webcam or USB scanner to jump straight to any bin. Hardware engineers import KiCad bills of materials into project workspaces to calculate buildable board quantities and deduct stock in one step. Schematic designers can even connect Part-DB as a native KiCad 8 HTTP library source to place verified lab components with pre-linked footprints directly inside their EDA editor. Fine-grained group permissions, SAML single sign-on, WebAuthn two-factor authentication, and a versioned audit log with rollback protect shared inventories.

Koillection is a self-hosted physical collection and inventory manager that organizes books, vinyl records, video games, stamps, trading cards, and any custom hobby catalog using hierarchical folders, reusable metadata templates, wishlists, and loan tracking. Collectors can structure nested sub-collections like a file system and attach tailored attributes to each item, ranging from star ratings, purchase dates, and country flags to autographs, PDF manuals, and video clips. Reusable item templates and choice lists standardize data entry across uniform categories so adding a new comic issue or board game takes seconds rather than repetitive typing. Custom HTML and JSON scrapers let you pull item titles, cover art, and structured fields directly from external catalog websites into your forms using XPath or JMESPath selectors. Cross-collection tags link related pieces across separate folders, while dedicated photo albums store supplementary event galleries or condition photographs alongside your main inventory. Built-in wishlists track desired acquisitions with target prices and currencies, and a loan manager records which friend borrowed an item and when it was returned. Granular visibility settings let households run independent multi-user accounts or share read-only collection pages with guests, and a REST API exposes every catalog entity for external automation.

Self-hosted and plugin-based, DVinyl keeps vinyl, CDs, cassettes, books, movies, video games, LEGO sets, and board games in one catalog, with cover art and metadata fetched for every item. Adding an item takes an ID, a camera scan of its barcode, or a bulk import from Discogs or Goodreads. Each media type is a plugin that switches on per collection, with Discogs behind music, TMDB behind film, IGDB behind games, and Rebrickable behind LEGO. Once cataloged, a collection appears as a grid, a compact table, or virtual shelves with spine view and customizable furniture. Custom lists, track playlists, and a wishlist of items still being hunted sit alongside. Music collections get live value estimates with price history charts, games show completion times, and printable QR codes and barcodes label the physical copies. Separate collections can belong to you, the family, or a room, each with admin, editor, and viewer roles and optional OIDC single sign-on through Authentik, Keycloak, Authelia, or pocketID. Read-only links and QR codes let anyone browse a whole collection or just one section. Fourteen themes in light and dark, a modular dashboard, and a Markdown info page with photos make each instance personal. A no-code editor adds custom item types.

Instead of paging through albums, Photofield lays a whole photo library out on one zoomable canvas, where thousands of thumbnails sharpen into full-resolution pictures as you zoom. Collections come straight from directories named in a configuration file. One setting turns every subfolder into its own collection. Pick a layout per collection: album grouped by date, timeline with month markers, wall, map, highlights with dates and place names, or flex. Sort oldest first, newest first, or shuffled hourly, daily, weekly, or monthly. Tiles load progressively, and an info drawer shows the date, file name, and dimensions. A right-click menu opens or copies an image, copies its link, or finds similar images. Originals are never modified, so a read-only mount is safe. Indexing runs at up to 10,000 files per second on a fast SSD with a warm cache. JPEG, PNG, AVIF, HEIC, DNG, GIF, MP4, and MOV files are recognized. Place names resolve from an embedded database, with no external lookups. The optional photofield-ai companion adds search by words like beach sunset or cat eyes, plus a Faces layout of detected faces. Alpha tagging lets you label photos.

HomeGallery turns the photo and video folders on your server into a mobile-friendly web gallery. Your files and folder structure stay exactly as they are. Point it at camera files, phone files, or offline drives, and previews and metadata are extracted once. Scroll one endless stream, newest first. Open any image for its file name, dimensions, capture date, source paths, camera settings, street address, tags, and detected objects. Swipe between photos, then pinch or double-tap to zoom. The Map view clusters photos by place, with counts. The plant button lists similar images, so one sunset finds every other sunset. Face search finds the same person in other photos. A search box accepts expressions like tags in (vacation, family), type:video year in [2015:2020] order by duration, or not exists(geo). In Edit mode, select many photos at once and type comma-separated tags; a minus prefix removes one. Videos are transcoded for playback. Renamed or moved files keep their previews. An archive disk can stay unplugged once indexing is done. Optional logins limit each user to a query filter. Install it as a PWA for a lightweight mobile app. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
