PCBJam Review 2026: Real KiCad in Your Browser, No Install

PCBJam is the closest thing yet to “KiCad, but it just works in a tab.” Instead of re-implementing a PCB editor for the web, the team compiled the genuine KiCad engine to WebAssembly and ran it in the browser. You get Eeschema for schematics, Pcbnew for layout, the interactive router, DRC/ERC, a 3D board view, and Gerber/BOM export — the same .kicad_pcb files you’d open on desktop.

What PCBJam Does

PCBJam is a browser-native PCB design tool built on the real KiCad engine. Open a .kicad_pcb or start from the demo board, and within seconds you’re routing traces — no install, no toolchain, no account. It runs on Mac, Linux, Windows, Chromebook, and even iPad, as long as there’s a modern browser.

Use Cases

• Students and hobbyists who don’t want to install a multi-GB EDA suite just to open one board.
• Cross-platform designers moving between a Chromebook, iPad, and desktop.
• Teams who want cloud storage, sync, and shared workspaces (paid tier).
• KiCad users who want the same engine without leaving the browser.

Key Features

Real KiCad Engine (WASM)

This isn’t a stripped-down web clone. It’s the actual KiCad source compiled to WebAssembly — schematic capture, multilayer layout, design-rule checks, 3D view, footprint and symbol libraries, net classes, and push-and-shove routing all present.

Zero Install

Drag in a .kicad_pcb or .kicad_sch and it opens in seconds. Your files stay in the open KiCad format, so you can walk away with every byte whenever you want.

Open & Portable

The editor and format are free and open source (GPL). Self-hosting and an offline PWA are on the roadmap. No proprietary lock-in.

Multiplayer (Coming)

Live cursors, presence, and conflict-free co-editing (CRDT/Yjs) are rolling out to a waitlist first.

Pricing

The core editor is free — design entirely in your browser with files stored locally on your machine. Paid features are the cloud: hosted storage, cross-device sync, and shared team workspaces.

How It Compares

Tool	Browser	Open source	Full editor
PCBJam	✅	✅	✅
KiCad	❌ (desktop)	✅	✅
EasyEDA	✅	❌	✅
KiCanvas	✅	✅	❌ (viewer)
Flux	✅	❌	✅

PCBJam is the only full editor that is both browser-native and open source.

The Verdict

If you live in the KiCad ecosystem and want to design from any device without installing anything, PCBJam is the cleanest option available in 2026. One honest caveat: despite the “AI tools” framing of this site, PCBJam is not an AI-native tool — AI assistance is only an opt-in roadmap item. Expect a fast, faithful KiCad that happens to live in a tab, not an “AI hardware engineer.”
