PCB design tools, compared honestly

PCB tools are not interchangeable. KiCad gives you local files and open-source control. EasyEDA shortens the path to JLCPCB and LCSC. Altium sells a deeper professional toolchain. Quilter automates placement and routing inside tools teams already use. LibrePCB offers a smaller open-source alternative. Flux puts collaboration and an AI assistant in a browser workspace.

The honest choice starts with constraints: who owns the files, whether the tool must work offline, how the team reviews changes, where boards get fabricated, and whether automation saves enough time to cover its cost. Pick the failure mode and operating model you can live with, not the longest feature list.

How they compare

Prices and vendor-specific details are limited to each company’s cited pages. Product descriptions summarize how the vendors position their tools. “Not covered by the sources cited on this page” means the cited source does not address that column, not that a feature is absent.

KiCad: local control, no seat tax

KiCad is a free, open-source, cross-platform PCB design suite for schematic capture and PCB layout; its own homepage describes using it “all forever free” ^[3]. Start with KiCad when local files, open-source licensing, and no recurring seat cost matter more than browser collaboration or an AI assistant built into the editor. The tradeoff is operational: your team owns file sharing, version control, libraries, review conventions, and workstation setup.

Flux makes link sharing and browser access simpler. KiCad gives you more control over the files and removes the subscription. Neither is free of friction; they put the friction in different places.

EasyEDA: the fastest path to a JLCPCB order

EasyEDA offers a free Standard Edition for schematic capture and PCB design, and integrates directly with JLCPCB for one-click PCB ordering and with LCSC for parts ^[4]. If your workflow already ends with a JLCPCB order, EasyEDA puts design, ordering, and parts sourcing in one path with fewer handoffs.

The cost of that convenience is dependency: EasyEDA’s headline integration is with one specific fab-and-distributor pairing ^[4]. In our view that’s a strength if JLCPCB and LCSC are already your supply chain, and a constraint worth weighing if they aren’t.

Quilter: an AI layer, not a Flux replacement

Quilter isn’t a standalone EDA package the way KiCad or Altium are. It’s a physics-driven AI tool that automates PCB placement and routing, with native support for the major ECAD formats (Altium, Cadence, Siemens, KiCad, OrCAD), so a design can be uploaded from an existing tool and returned in its original format ^[5]. That makes it something you add to a workflow you already have, not something you switch to.

Pricing is per project rather than per seat, scaled to how many pins need routing, with no annual licenses. No rates are published, and getting a number means contacting sales ^[6]. That opacity is the honest downside: you can’t budget for Quilter the way you can budget for a $20/mo or even a $995/yr line item until you’re already in a sales conversation.

LibrePCB: the leaner open-source option

LibrePCB is a free, open-source (GPLv3), cross-platform EDA suite for drawing schematics and designing printed circuit boards ^[7]. It is a legitimate local, open-source option, but this page’s cited source does not establish that its libraries, plugins, team workflows, or production track record match KiCad’s.

Test it against a representative board and your actual library workflow before committing.

Altium Develop: for professional budgets

Altium’s professional PCB design offering, Altium Develop, is positioned as an “affordable package for engineers and small teams,” with additional Altium Designer author seats priced at $995 per year each ^[8]. For teams already budgeting for professional EDA tooling, where Flux’s $142/mo Pro tier ^[2] isn’t itself the barrier, Altium offers a professional toolchain. The source cited here supports the price and positioning, not every feature or a blanket claim that Altium is better.

Cost and complexity scale together. $995/yr per additional author seat adds up fast for a growing team ^[8], and Altium’s feature depth comes with a steeper learning curve than lighter, browser-based tools built for smaller boards.

Flux: browser collaboration with a seat cost

Flux makes sense when the shared workspace saves more time than the subscription and cloud dependency cost you. Browser access avoids desktop installation, and the AI copilot works in the same environment as the design. Those are workflow advantages, not proof that the resulting board will be better.

Teams used to link-based collaboration may find Flux’s model familiar. Starter provides a way to test that workflow at $20 per month ^[1]. Pro costs $142 per editor per month and includes 100 ACUs per editor ^[2]. The higher tier makes the most sense only when the AI and collaboration features save enough engineering time to justify the seat cost. Measure that on a real project before moving the team.

Where PCBWiki fits

None of the above is what PCBWiki does. We cover individual parts: verified specs, pinout gotchas, and drop-in alternatives like the LM358 or the ESP32-WROOM-32. Once you’ve settled on a design tool, that’s the page to go to next.
