Is KiCad or Lonboard better?

Neither clearly leads. KiCad starts at Free and Lonboard at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, KiCad or Lonboard?

KiCad starts at Free and Lonboard at Free.

Does KiCad or Lonboard run on more platforms?

KiCad runs on Windows, macOS, Linux. Lonboard runs on Linux, macOS, Windows.

Can I use KiCad for free?

Both have a free tier, so you can try either at no cost before committing.

What is KiCad best used for?

KiCad is most often used for a hardware startup designing a multi-layer board without paying for an altium seat, a university teaching pcb design where per-student licences are unaffordable, an open hardware project that needs design files anyone can open and modify, an engineer prototyping a board at home who needs commercial rights on the output. Of those, a hardware startup designing a multi-layer board without paying for an altium seat and a university teaching pcb design where per-student licences are unaffordable are not what Lonboard is typically brought in for.

What can KiCad do that Lonboard cannot?

KiCad covers Schematic capture, PCB layout, No design limits, 3D viewer. Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget.

The short version

Each has a real cost: KiCad there is no vendor obligation behind the free software, so a blocking bug is escalated to a volunteer community unless you separately buy a contract from KiCad Services Corporation.; Lonboard it is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file
They diverge on capability: KiCad covers Schematic capture, Lonboard covers GeoArrow binary transfer.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

KiCad

There is no vendor obligation behind the free software, so a blocking bug is escalated to a volunteer community unless you separately buy a contract from KiCad Services Corporation.
High speed design support, including advanced constraint management, differential pair and impedance tooling, remains behind Altium and Cadence, which matters as soon as boards carry fast interfaces.
Rigid-flex and complex stack-up design is weak, so products with flex circuits usually need a commercial package.
Component library and part sourcing integrations are thinner than the commercial tools, so parts data and availability checking is manual work someone has to own.
Multi-engineer design data management is not provided; teams end up assembling Git workflows themselves, and merge handling on binary-adjacent design files is awkward.

Lonboard

It is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file
Maintenance sits with Development Seed as an open source side output of a consultancy, so roadmap priorities follow client projects and there is no support contract to buy
Layer coverage is a subset of deck.gl, so an analyst needing a less common layer type has to drop to pydeck or write JavaScript rather than staying in Python
It expects data already in GeoPandas or Arrow form, which means the performance benefit depends on the rest of your pipeline being Arrow-friendly; reading a large Shapefile is still the slow step
Rendering happens in the browser, so very large datasets are ultimately limited by the client machine's memory and GPU rather than by the server, and a laptop will still fail on data a workstation handles

Answered from the vendors’ own pages

KiCad: Is KiCad really free for commercial work?

Yes. It is GPL licensed with no restriction on commercial use, board size, layer count or component count.

Lonboard: Why not just use pydeck?

pydeck serialises geometry to GeoJSON to reach the browser. Lonboard uses a binary GeoArrow pipeline, which is the reason it handles far larger datasets in the same notebook.

KiCad: Can I buy support?

Yes, but not from the project. KiCad Services Corporation sells commercial support contracts separately; CERN moved to exactly that arrangement after ending its donation programme.

Lonboard: Who maintains it?

Development Seed, a geospatial engineering consultancy, as an open source project. There is no commercial support offering.

KiCad: How is development funded?

Through donations and sponsors administered via The Linux Foundation, plus contributed engineering time.

Lonboard: Does it work outside Jupyter?

It is built as a Jupyter widget. Exporting to standalone HTML is possible, but the intended environment is a notebook.

KiCad: Is it good enough to replace Altium?

For most low and medium speed boards yes. For high speed, rigid-flex and heavily constrained designs, the commercial tools still hold a clear lead.

Lonboard: Is it free for commercial use?

Yes, it is open source with no licence fee.
