KiCad vs Fusion Electronics: the Eagle successor compared

If you designed boards in Autodesk Eagle, the decision has been made for you: Autodesk will stop selling and supporting standalone Eagle on June 7, 2026, and its functionality now lives inside Autodesk Fusion as the Electronics workspace. So the real question isn't "Eagle or something else" — it's whether to follow Eagle into Fusion, or move to KiCad instead.

Short answer: If you want a free, fully-owned, offline toolchain with no board-size or layer limits, KiCad is the natural landing spot for former Eagle users. If you want board and enclosure in one application with live ECAD-MCAD sync — and you're happy in the Autodesk cloud ecosystem — Fusion Electronics is the reason to pay. Both open your existing Eagle files.

What actually happened to Eagle#

Autodesk folded Eagle into Fusion. Effective June 7, 2026, Eagle is no longer sold or supported as a standalone product; the schematic and PCB editors were rebuilt as the Electronics workspace inside Fusion. Autodesk states that Eagle files are fully compatible with that workspace, so existing projects carry over. There is no more perpetual or standalone Eagle license to buy — access to that functionality comes through a Fusion subscription.

KiCad, by contrast, imports Eagle projects directly (File → Import), so migrating away from Autodesk is also a supported path. Automated conversion is never perfect — custom footprints and library parts are the usual trouble spots — so review the result before you send anything to a fab. We cover this in more depth in KiCad vs Eagle.

Cost and licensing#

This is the starkest difference.

KiCad is free under the GPL with no per-seat license, no feature tiers, and no expiry — the boards you design are yours to manufacture and sell. Fusion Electronics is bundled into a paid Fusion subscription (published by Autodesk in the low-hundreds-of-dollars-per-year range at the time of writing), which also gets you Fusion's mechanical CAD, CAM, and simulation.

The free-tier trap#

Fusion does have a free "Fusion for Personal Use" tier, and it's genuinely useful for hobby mechanical CAD. But the electronics side is deliberately limited. As widely reported by users, the free tier restricts you to roughly:

A two-layer, palm-sized board is fine for a blinking-LED project — but you hit those walls quickly on anything real, and the free tier is non-commercial only. KiCad has no such caps: 32 copper layers, any board size, commercial or not. If free-and-unlimited is what you're after, see best free PCB design software.

Where Fusion Electronics genuinely wins#

Fusion's standout advantage is real and worth naming: ECAD-MCAD integration. Because the electronics and mechanical workspaces live in the same application, you can push a board into the 3D model, design the enclosure around it, and pull mechanical changes (mounting holes, connector positions, keep-outs) back into the PCB — with bidirectional sync rather than exporting and re-importing files. If your product is as much about the enclosure and mechanics as the circuit, that single-tool workflow is hard to beat.

Fusion also brings library and supplier data into the same Autodesk ecosystem, cloud-hosted project data, and a familiar home for anyone already using Fusion for mechanical work.

Where KiCad wins#

KiCad's files are plain text on your disk, which makes them ideal for Git — real history, diffs, and reproducible releases — and means nothing disappears if a subscription lapses. It runs natively on Linux, which Fusion does not. And there's no vendor lock-in: the format is open and the tool is open source. For high-speed and controlled-impedance work KiCad is also very capable — stackup editor, impedance calculator, and length/delay tuning — which pushes it well past Eagle's old ceiling and into territory we explore in Altium vs KiCad.

On the ECAD-MCAD question specifically, KiCad doesn't host mechanical design, but it does export clean STEP models that drop into any mechanical CAD tool — the mechanics of which we walk through in KiCad 3D STEP export. It's a hand-off rather than a live link, but it's format-neutral and free.

Who each is for#

Choose Fusion Electronics if: you're already in the Autodesk ecosystem, your product needs tight board-and-enclosure co-design with live ECAD-MCAD sync, and a subscription fits your budget. It's also the lowest-friction path if you have a large existing Eagle library and want to stay put.

Choose KiCad if: you want a free, fully-owned toolchain with no layer or board-size limits, you value local files and Git, you work on Linux, or you're a student, hobbyist, or small team who'd rather not pay a recurring subscription for the electronics you already know how to do.

The workflow gap — and closing it#

Whichever editor you land on, finishing a layout is only half the job. You still have to generate Gerbers, drill files, a BOM, a pick-and-place file, and DRC reports — by hand, every revision — and keep them all in sync. Fusion bundles some of this into its output flow; KiCad ships kicad-cli to script it, but wiring that into a repeatable process is left to you.

That's the gap GoForFab closes for KiCad specifically. Connect a KiCad project and every push regenerates the full manufacturing package automatically — Gerbers, BOM, CPL, DRC and ERC reports, 3D renders — so your outputs are always current and always reproducible. It's free forever, and it turns the "outputs by hand" chore into something you never think about again.

If your workflow is KiCad, that's the missing piece. If you're leaning toward Fusion, note that GoForFab is KiCad-only — but the same discipline (automate your outputs, version your files) is what makes any toolchain feel professional.
