SnapEDA's free part library still exists. It is now called SnapMagic Search, and snapmagic.com is a separate AI design copilot. People look for an alternative for four reasons: the part is not there, the footprint is for the wrong package, the KiCad plugin does not support current KiCad, or they want a second source to cross-check a model. This page covers each case, with every vendor fact checked on the vendor's own site.

Quick answer
The closest free alternatives to SnapEDA (now called SnapMagic Search) are Ultra Librarian and SamacSys Component Search Engine, which also host symbols, footprints and 3D models for manufacturer part numbers. For LCSC parts, easyeda2kicad converts EasyEDA models to KiCad, and KiCad's own libraries and footprint wizards cover standard packages. If no library has the part, Component Search Engine takes free 48-hour build requests, SnapMagic builds one for $29 in one business day, or an AI generator such as ProtoFlow's drafts it from the datasheet in about a minute for you to check.

SnapEDA, Inc. now does business as SnapMagic. The part library at snapeda.com is branded SnapMagic Search. It says it has 10 million parts from over 2,500 manufacturers, and its home page lists about 20 PCB tools it supports, including KiCad, Altium, Autodesk Fusion, Eagle, OrCAD, Cadence Allegro and PADS. Downloads are free, and the pricing page says the library is free for designers and always will be.
snapmagic.com is a different product. It presents SnapMagic as an AI copilot for electronics design, built on the SnapEDA model database, with an early-access signup and no public price. If you searched for SnapMagic and wanted the free library, that is SnapMagic Search at snapeda.com.
Downloaded design files are licensed under CC BY-SA 4.0 plus SnapMagic's Design Exception 1.0, which covers designing, manufacturing and distributing boards that use them. For missing parts there are two paths. InstaBuild is a free beta on select part pages: you highlight the pin table in the datasheet and it builds a symbol linked to an existing verified footprint. InstaPart is a paid service at $29 a part (up to 100 pins), or $20 a part when you buy 20 credits, delivered in one business day.
The part is missing. No library models everything. New parts, niche connectors and parts sold mostly through LCSC are the usual gaps.
The model is wrong, or it is for a different package variant. KiCad forum threads about SnapEDA and other library sites describe footprints that needed edits before use, and users disagree about which site is cleaner. Quality varies by part on every site, so a second source is worth having for cross-checks.
The KiCad plugin is out of date. SnapMagic's plugins page lists its KiCad plugin as optimized for KiCad up to 5.1.10 (beta), and a SnapMagic support answer says its desktop app does not support KiCad 9. Website downloads still work in current KiCad.
The download is missing a format or a 3D model you need. In that case, try the next source in the table above.
All three are free libraries of symbols, footprints and 3D models for specific manufacturer part numbers. The differences that matter in practice are coverage for your exact part, the export format for your tool, and what happens when the part is missing.
Ultra Librarian says it has over 16 million verified symbols, footprints and 3D models and exports to over 30 CAD formats, KiCad included. Downloads are free, and registration is free. For parts it does not have, its Virtual Librarian Service builds them for teams with a 48-hour standard turnaround (24 hours at extra cost), set up through a meeting rather than a public price list.
SamacSys, now part of Supplyframe, runs Component Search Engine. It offers free symbols, footprints and 3D models for millions of parts, which you can download directly or install with its Library Loader app. Its KiCad page lists two options for parts that are new to the market: a free build request with a 48-hour turnaround, or a web-based tool to build the part yourself.
Which one is better depends on the part. The library sizes are each vendor's own claim and are not counted the same way. For a mainstream part, search the exact manufacturer part number, package suffix included, on two of the three and compare both footprints with the datasheet. For a missing part, Component Search Engine's free 48-hour request is the cheapest path if you can wait. SnapMagic's InstaPart has a published per-part price and one-business-day delivery. Ultra Librarian's service is aimed at teams with ongoing library work.
Skip the plugin. On the part page, download the KiCad (V6 and later) format. SnapMagic's import guide says to extract the zip as-is, without renaming the folder. Add the .kicad_sym file under Preferences, Manage Symbol Libraries. Add the folder that holds the .kicad_mod files under Preferences, Manage Footprint Libraries. Then open the footprint in the Footprint Editor and confirm the 3D model path resolves.
The same two library manager dialogs are where any downloaded .kicad_sym file or footprint folder goes, whichever site it came from.
Parts sold by LCSC are identified by an LCSC number such as C2040. easyeda2kicad is an open-source Python tool (AGPL-3.0) that converts EasyEDA and LCSC components into a KiCad symbol, footprint and 3D model, saved as both WRL and STEP, for KiCad 6 and newer. Install it with pip install easyeda2kicad, then run easyeda2kicad --full --lcsc_id=C2040. Its README says the correctness of converted parts cannot be guaranteed, so check them before use.
ProtoFlow's real parts library also publishes KiCad symbols, footprints and 3D models for LCSC parts that ProtoFlow engineers imported and used in real designs. They are free to download.
You have five options. Request it from Component Search Engine for free and wait about 48 hours. Buy an InstaPart from SnapMagic for $29 and get it in one business day. For a standard package, use a KiCad footprint wizard: the KiCad 10 manual lists wizards for BGA, QFN, QFP, SOIC-family, SIP, DIP and ZIP packages, FPC connectors and more, driven by dimensions you type in from the datasheet. Draw the part yourself in the symbol and footprint editors. Or draft it with an AI part generator.
ProtoFlow's free AI part generator reads a part number, datasheet PDF, datasheet URL or pinout image and returns a linked symbol and footprint, so pin 1 on the symbol is pad 1 on the footprint. It reads the land pattern from the datasheet and builds the pads from the documented dimensions. It exports KiCad (.kicad_sym and .kicad_mod), EAGLE (.lbr), Altium (.SchLib and .PcbLib) and Allegro files. A generation takes about a minute. A free signed-in account gets 10 generation units a month. A 3D model (STEP and WRL) is a Pro and Max option.
Treat the output as a draft. The generator shows the full pin and pad tables and any warnings, and you should check them against the datasheet, as you would for any library part you did not draw. The same generator runs inside the free ProtoFlow desktop app as the AI Component Lab, which saves the part to your library so you can place it in a schematic.
Whatever the source, open the datasheet's recommended land pattern and check pad pitch, pad size, courtyard and pin 1. Compare the symbol's pin numbers with the pinout table, not just the pin count. For a part with an exposed pad, check its size and whether the datasheet calls for vias. Then run ERC and DRC in your EDA tool before you release the design.
| Your situation | Try first | If that fails |
|---|---|---|
| Mainstream manufacturer part | Search the exact part number on SnapMagic Search, Ultra Librarian and Component Search Engine. | The CAD link on the manufacturer's product page, then a build request. |
| LCSC or JLCPCB part | easyeda2kicad with the LCSC number. | Generate it from the datasheet and check it. |
| Standard package (SOIC, QFN, 0603, header) | KiCad's built-in footprint libraries. | A KiCad footprint wizard with datasheet dimensions. |
| Missing part, can wait two days | Free Component Search Engine build request (48 hours). | SnapMagic InstaPart, $29, one business day. |
| Missing part, needed today | An AI-generated draft, checked against the datasheet. | Draw it in the KiCad symbol and footprint editors. |
| Using KiCad 9 or 10 | Website download in the KiCad (V6 and later) format. | easyeda2kicad (KiCad 6 and newer) for LCSC parts. |
| Need a 3D model | SnapMagic, Ultra Librarian, SamacSys and easyeda2kicad offer them for many parts. | ProtoFlow generates STEP and WRL on Pro and Max plans. |

There is no single best one. Ultra Librarian and SamacSys Component Search Engine are the closest like-for-like libraries: free, with symbols, footprints and 3D models for manufacturer part numbers. Use easyeda2kicad for LCSC parts, KiCad's built-in libraries for standard packages, and a build request or an AI generator when no library has the part.
Yes. SnapEDA, Inc. does business as SnapMagic, and the free library at snapeda.com is now called SnapMagic Search. snapmagic.com is a separate AI copilot product with an early-access signup.
Yes. SnapMagic says its library of symbols, footprints and 3D models is free for designers. Downloaded files are licensed under CC BY-SA 4.0 with a Design Exception that covers designing, manufacturing and distributing boards. Paid InstaPart credits are only for custom parts it does not have yet.
The site has run since 2013, and part downloads are CAD files: symbols, footprints and 3D models. The practical risk is a model with an error, which can happen on any library site. Check the footprint against the datasheet before you order boards.
Neither wins for every part. Ultra Librarian says it has over 16 million verified models and over 30 CAD formats. SnapMagic says it has 10 million parts and supports about 20 PCB tools. User reports in forums go both ways. Search both for your exact part number and compare the footprints with the datasheet.
Both are free. SamacSys runs Component Search Engine and the Library Loader app, and it builds a missing part for free with a 48-hour turnaround. SnapMagic offers InstaBuild on select part pages and charges $29 a part for custom InstaPart builds delivered in one business day.
SnapMagic lists its KiCad plugin as optimized for KiCad up to 5.1.10, and a SnapMagic support answer says its desktop app does not support KiCad 9. Download the KiCad (V6 and later) files from the website instead and add them in the symbol and footprint library managers.
SnapMagic's InstaBuild uses computer vision and OCR to build a symbol from a datasheet's pin table on select part pages. SnapMagic describes it as linking that symbol to an existing verified footprint. Separate AI tools, such as ProtoFlow's free part generator, draft both the symbol and the footprint from a datasheet. Check the result before you use it.
Search Ultra Librarian and Component Search Engine with the exact part number. If it is an LCSC part, try easyeda2kicad. If nothing has it, request a free build from Component Search Engine, buy an InstaPart from SnapMagic, use a KiCad footprint wizard for a standard package, or draft it from the datasheet with an AI generator.
