Roundup
Online PCB tools mean no install and easy collaboration, but "online" covers a few different things — full browser ECAD, cloud routing services, and AI copilots. Here is how the main options compare, and when a local desktop tool is actually the better call.
Quick answer
The leading online, browser-based PCB tools in 2026 are EasyEDA (free, tied to JLCPCB/LCSC) and Flux (collaborative ECAD with an AI copilot), while Quilter and DeepPCB are cloud AI routers. If you specifically want a browser tool, start with EasyEDA or Flux. If you want AI to draft the schematic and prefer local files and privacy, ProtoFlow is a free desktop alternative that exports to KiCad.

| Tool | Type | Best for | Cost |
|---|---|---|---|
| EasyEDA | Browser ECAD | Free design + JLCPCB ordering | Free tier; paid |
| Flux | Browser ECAD + AI copilot | Real-time team collaboration | Free trial, then paid |
| Quilter | Cloud AI router | Autonomous routing | Free tier, then paid |
| DeepPCB | Cloud AI router | Autonomous routing | Free tier, pay-as-you-go |
| ProtoFlow | Desktop AI capture (local files) | AI schematic capture → KiCad | Free |
EasyEDA runs entirely in the browser, is free, and connects directly to JLCPCB/LCSC for parts and ordering, which makes it a fast path from design to a manufactured board. Flux is a browser ECAD environment built around real-time collaboration and an AI copilot, so distributed teams can work in one shared workspace.
If your priority is "no install, work from anywhere," these two are the main choices.
Quilter and DeepPCB are cloud services rather than full editors: you hand them an existing board and they route it with AI. They are "online" in the sense that the heavy computation runs in the cloud, but they are not where you draw your schematic.
A browser is not always the right home for your design. If you care about IP privacy, want your files local, or simply want AI to draft the schematic for you, ProtoFlow is a free desktop tool that does exactly that, then exports a standard KiCad project you can take to any of the tools above.
A practical hybrid: capture with ProtoFlow locally, then collaborate or order online in Flux or EasyEDA, or route in the cloud with Quilter or DeepPCB.
| Criteria | ProtoFlow EDA | Browser-based PCB tools |
|---|---|---|
| Where it runs | Desktop app, local files. | In the browser / cloud. |
| AI role | Drafts the schematic from plain English. | Copilot (Flux) or routing (Quilter/DeepPCB). |
| Privacy | Files stay on your machine. | Designs live in the cloud workspace. |
| Collaboration | Hand off via KiCad export. | Real-time multiplayer (Flux) is a strength. |
| Best fit | AI capture with local control. | No-install design and team collaboration. |

For free browser design with built-in ordering, EasyEDA. For collaborative browser ECAD with an AI copilot, Flux. For cloud AI routing, Quilter or DeepPCB. If you prefer local files with AI capture, ProtoFlow is a free desktop alternative.
Yes — EasyEDA has a free browser tier, and Quilter/DeepPCB have free routing tiers. ProtoFlow is a free desktop option if you do not need to work in the browser.
Privacy and control. A desktop tool like ProtoFlow keeps your design files local and works without a live cloud workspace, while still exporting to standard KiCad for any downstream tool.
