How do I open a .kicad_mod file?

Drop a .kicad_mod file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open KiCad schematics, circuit boards, footprints and projects in the browser. Analyser parses the S-expression documents - schematics (.kicad_sch), boards (.kicad_pcb), symbol libraries (.kicad_sym) and footprint modules (.kicad_mod), including the "-bak" backups - and rebuilds the geometry as an interactive vector view: schematic symbols, wires, junctions and labels, or the board outline, copper tracks, pads, vias, zones and silkscreen, with pan, zoom and per-layer visibility toggles. It reads the project settings (.kicad_pro / .kicad_prl JSON) with its net classes, the library tables, the footprint cache and the ngspice simulation workbook (.wbk), and plots the SPICE simulation waveforms (.raw) from KiCad/ngspice or LTspice - decoding the analysis type, variables and samples to chart the traces or tabulate an operating point. Dropping a whole project folder opens every document together as one design with a combined bill of materials that cross-probes each part to its symbol on the schematic and its footprint on the board. Nothing is uploaded.

Can I open a .kicad_mod file online for free?

Yes. Analyser is a free online .kicad_mod opener and viewer that runs entirely in your browser - your .kicad_mod file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What is a .kicad_mod file?

A .kicad_mod is a KiCad footprint module - one land pattern (pads, courtyard and silkscreen) a component solders to. Created and opened by KiCad.

Did you know: Footprint libraries are simply folders ending in .pretty, each holding one .kicad_mod file per footprint.
Analyser handles .kicad_mod alongside related formats such as .kicad_sch, .kicad_pcb, .kicad_sym and more.
In Analyser's format library, .kicad_mod sits in the 3D / CAD / engineering category.
