Etch it tonight Free

Print a mirrored 1:1 mask for toner transfer or UV photoresist and etch the board on your kitchen table. Got a laser? The same export cuts a solder paste stencil, corrected for the beam's kerf.

Order it from a fab Engineer

Gerber X2 and Excellon drill files that JLCPCB, PCBWay, OSH Park or Aisler take as they are, with paste layers for a stencil. Number your parts R1, C3, U2 and export the parts list for LCSC or JLCPCB — that part is free.

Show it off Free

Share a link that opens the board in 2D or 3D — chat apps show a picture of it in 3D beside the link. At a fair, Showcase runs it full screen, turning on its own, with a QR code that opens it on a visitor's phone.

Everything a prototype needs. Nothing it doesn't.

The editor with copper routed pad to pad and the track width panel open

WYSIWYG Layout Editor

See exactly what you'll get. Place footprints, route copper by hand or let the autorouter do it, and arrange your board visually — what you see on screen is what gets fabricated. No netlist required.

Cloud Sync, Offline Too

Your boards are backed up and synced across your devices — pick up on your phone where you left off on the web. No signal? Offline mode keeps you working and uploads when you're back, and unsaved changes survive a crash.

Turn the board like one in your hand, in the mask colour and finish you'll order — HASL, ENIG or OSP. It is drawn from the same openings the Gerber export writes, so a pad left under the mask shows before you pay for it.

3,400+ Footprints

From 0402 resistors to Espressif's own ESP32 modules and 114 74-series chips with their pins named. Search forgives spelling — "kapasitor", "elco", "4k7" — and you can import from KiCad or any public GitHub repository.

The Design Rule Check panel reporting no violations

Design Rule Check

Catch shorts, clearance violations, and unconnected copper before you order. DRC runs right in the editor and points at every problem on the board.

Ground Pours & AutoGround

Fill copper areas with a tap. AutoGround pours the ground plane around your traces and keeps it up to date as your layout changes.

The fiddly parts, generated.

A spiral inductor, a grid of forty vias, mounting holes that actually line up with an Arduino — tedious to draw and easy to get wrong. Open Insert, answer a few questions, and finished geometry lands on the board.

.lay6 · .lay

Sprint Layout

Open .lay6 and Sprint 5 .lay files as full projects — boards, traces, pads and all — and, on Maker, bring in .lmk macros. Design on from where Sprint Layout left off, now on iPhone, iPad, Android and the web. How to import .lay6 files →

.kicad_pcb

KiCad

Open .kicad_pcb boards as full projects, free on every plan — the layout comes across and you keep working on it here. On Maker, bring in single .kicad_mod footprints too, from a file or straight from GitHub. How to import from KiCad →

.brd

Eagle

Open your .brd board files as full projects — the layout you built in Eagle comes across, with its text and its real board outline, so you can keep working on it here, on any device you own. How to import .brd files →

Each importer was checked against real boards — 869 from KiCad, 2,307 from Eagle and 58 from Sprint Layout — and the last two against the Gerbers those tools export themselves. Opening Sprint Layout, KiCad and Eagle boards as new projects is free on every plan — we never gate the way in; only the cloud-board limit applies. Importing single footprints and macros starts with the Maker plan.

From idea to board in three steps.

1

Place components

Search the built-in footprint library, import from KiCad, or pull footprints from any public GitHub repo — then drag parts straight onto the board.

2

Route your traces

Draw copper pad-to-pad, pour ground planes with AutoGround, and let the Design Rule Check flag shorts and clearance issues as you go.

3

Export & build

Turn it in 3D to check it, then export Gerber files any PCB fab accepts, or a mirrored PDF mask to etch the board at home. Your design becomes a real board.

Frequently asked questions

Is Protoboard Designer free?

Yes. You can design a board and etch it at home for free. You only need a free account, with no credit card and no trial period. The editor, the autorouter, the footprint library and PDF export for home etching will always be free.

That covers the full editor with the autorouter, ground pours and Design Rule Check, 3,400+ footprints plus 5 of your own, copper on both sides with silkscreen, unlimited boards on your device with 3 synced to the cloud, and opening your Sprint Layout, KiCad and Eagle boards. When it's ready, print the mirrored 1:1 PDF for toner transfer or UV exposure. A small footer line sits outside your board.

A plan adds extras if you want them:

  • Maker, $5.99/month: several boards per sheet (mosaic printing), no watermark, footprint import from KiCad and GitHub, and generators such as coils and QR codes.
  • Engineer, $10.99/month: everything in Maker, plus Gerber and drill files so a factory can make the board for you, thermal pads, and the antenna and via stitching generators.
Is Protoboard Designer an online PCB editor?

Yes. Protoboard Designer runs entirely in your browser as a WebAssembly web app — there's nothing to install. It's a full online PCB editor: design boards, route copper, run a Design Rule Check, and export Gerber or PDF files. The same editor is also available as an iPhone, iPad and Android app, and your projects sync between them.

Do I need EDA or PCB design experience?

No. Protoboard Designer is a WYSIWYG editor: you place footprints and draw copper traces directly on the board — no schematic or netlist required. What you see on screen is what gets fabricated.

Can I import KiCad footprints?

Yes, and whole boards too. Opening a .kicad_pcb board as a new project is free on every plan. Importing single footprints is part of the Maker plan: pick a .kicad_mod file, or browse any public GitHub repository and place the part you need. Footprints come in one at a time and go onto your board. To reuse one later, save it to My footprints.

Can I open my existing Sprint Layout, KiCad, or Eagle designs?

Yes. Sprint Layout .lay6, Eagle .brd and KiCad .kicad_pcb files all open as new projects — traces and pads included — free on every plan. We don't gate the way in; the only limit for free users is the number of cloud boards. Importing reusable footprint libraries (.kicad_mod, including straight from GitHub) and Sprint Layout .lmk macros starts with the Maker plan.

Can I order my board from JLCPCB, PCBWay, or another fab?

Yes. Protoboard Designer exports industry-standard Gerber X2 and Excellon drill files (Engineer plan), with the solder paste layers for a stencil, that any PCB manufacturer — JLCPCB, PCBWay, OSH Park, Aisler, and others — accepts directly.

Can I make a PCB at home for free?

Yes, on the free plan. Export your layout as a PDF mask — mirrored for toner transfer or photoresist — print it at 1:1 scale, and etch the board at home. Mirroring is free on every plan. Maker adds mosaic printing, which fits several copies of the same board on one sheet — so a sheet of transfer film or photoresist gives you spares instead of one board.

Does it work on my phone or tablet?

Yes. The full editor runs on iPhone and iPad, on Android phones and tablets via the Google Play app, and in any modern desktop browser as a WebAssembly web app. Projects sync between devices automatically.

Is there an iOS app?

Yes. Protoboard Designer is on the App Store for iPhone and iPad, and needs iOS 15 or later. It's the same editor as the Android and web versions, and your projects sync between all of them — so you can lay a board out on an iPad and pick it up on your desktop. If you'd rather not install anything, the web app still works in Safari.

How is it different from KiCad or Fritzing?

KiCad is a full schematic-driven EDA suite — powerful, but with a steep learning curve. Fritzing focuses on breadboard diagrams. Protoboard Designer sits in between: a direct, visual PCB layout editor that gets you from idea to a fabricatable board in minutes, on whatever device you have to hand. For complex multi-sheet schematic projects, a full EDA suite is still the right tool.

Can I see my board in 3D before I order it?

Yes, on every plan. The 3D view shows the board in the solder mask colour (green, purple, red, yellow, blue, white or black) and the surface finish (HASL, ENIG or OSP) you will order, and you can turn it like a board in your hand. X-ray shows the other side's copper. Showcase runs the turning board full screen for a fair or a demo, and a shared board opens in 3D from its link — no account needed to look.

Can I make a solder paste stencil?

Yes. The Gerber export (Engineer plan) writes the solder paste layers a stencil maker such as JLCPCB needs. To cut a stencil at home, the PDF export has a Solder Paste Stencil preset that compensates for your laser's kerf, with a test strip to measure it — free on every plan.

Can I export a parts list (BOM) for JLCPCB or LCSC?

Yes, on every plan. The Add designators tool numbers your parts R1, C3, U2 in board order, and the parts list export writes a CSV grouped by value and package for LCSC, Mouser or JLCPCB, with the quantity for as many boards as you build.

Does it work offline?

Yes. Offline mode keeps you working on the device and uploads your changes when you turn it off, and Download all brings every cloud board onto the device first. Without a connection the app still opens on your boards, and if it ever closes before a save, it offers your unsaved changes back.

Which languages does Protoboard Designer speak?

Thirteen: English, German, Spanish, French, Italian, Portuguese, Hungarian, Russian, Turkish, Korean, Hindi, Indonesian and Tagalog — using the terms makers in each language actually use. It follows your phone's language, or you can pick one in Settings.
