PCB Design Software Compared: KiCad, Altium, Eagle

The PCB design software landscape has shifted more in the last five years than it did in the previous twenty. KiCad went from "interesting open-source project that hobbyists tolerate" to "the actual best choice for most engineers". Altium remained the industry incumbent. Eagle's slow death continues. This article is the 2026 honest comparison.

The contenders

The PCB software landscape in 2026. KiCad and Altium dominate; the others occupy specific niches.

KiCad — the consensus 2026 pick

Free, open-source, cross-platform (Windows / macOS / Linux). The 9.0 release in 2024/2025 closed the last meaningful gaps with commercial tools. Used by hobbyists, startups, and increasingly by serious engineering teams.

What KiCad gets right:

• Genuinely free. No license, no "hobbyist version", no feature gating. Use it commercially without paying.
• Active development. CERN funding plus broad open-source community. Each release brings real improvements; the pace is faster than Altium's.
• Excellent libraries. The KiCad library covers most common parts. The community library project SnapEDA pulls in vendor footprints.
• Plugin ecosystem. Length matching, BOM exports, fab-specific output formats. The plugin manager makes installation one click.
• Native git integration. Files are text-based; meaningful diffs in pull requests.
• JLCPCB integration. The native fabrication output works directly with JLCPCB; community tools handle assembly.

What KiCad gets wrong:

• Library curation is uneven. The official library is solid but missing many parts; you build your own footprints frequently.
• Layer management is less polished than Altium for complex multi-layer designs.
• Differential pair routing improved a lot but still trails Altium.
• 3D rendering is functional but not pretty. Less useful for marketing renders than Altium or Fusion.

For 90% of engineers in 2026, KiCad is the right answer.

Altium Designer

The industry standard for hardware engineering teams at most established companies. $3000–5000 per seat per year (subscription model since the late 2010s).

What Altium gets right:

• Polished UI. Decades of iteration; everything has a place; muscle memory pays off.
• Best-in-class auto-routing. The auto-router works on real-world boards; KiCad's does not seriously compete.
• High-speed design support. Length matching, impedance control, signal integrity simulation are mature.
• Library management at scale. Vault, custom part libraries, vendor data integration. Critical for teams managing thousands of parts.
• Vendor support. When something breaks, there is a support contract.

What Altium gets wrong:

• Cost. $3K+/year per seat is a significant company expense. Hobby use is uneconomical.
• Subscription only. No more perpetual licenses since 2018. Stop paying, lose access.
• Windows-only. macOS users must use a VM or dedicated Windows machine.
• Bloated. Installer is several gigabytes; resource usage is heavy.
• File format proprietary. Migrating off Altium later is non-trivial.

If you work at a company that already uses Altium, the productivity is real. If you are starting fresh, KiCad first.

Autodesk Fusion (formerly Eagle)

Autodesk acquired Eagle in 2017 and is gradually merging it into Fusion 360 as the "Electronics" module. The standalone Eagle is being deprecated; new development is in Fusion.

The current state: capable enough for hobby and small-team work, with smooth integration to Fusion 360's mechanical design (helpful if you also do enclosure CAD). $30–65/month for Fusion with Electronics. Free tier available with limits (2-layer boards, single schematic sheet).

The honest verdict: legacy Eagle users on Fusion get reasonable value from the mechanical-electrical integration. New users should pick KiCad. Fusion Electronics is unlikely to displace KiCad or Altium.

EasyEDA

Web-based PCB tool from JLCPCB. Free. Tightly integrated with JLCPCB's component library and assembly service.

The strength: no installation, instant access to JLCPCB's parts, one-click ordering. Excellent for quick projects where the workflow ends at JLCPCB anyway.

The weakness: vendor lock-in. Your designs live in EasyEDA's cloud (or local files). Migrating to KiCad later requires manual conversion. Acceptable for hobby; risky for projects that may grow into businesses.

DipTrace

Capable mid-range tool, niche following. $145–700 perpetual license depending on board complexity. Decent for engineers who specifically dislike KiCad's UI and cannot afford Altium.

Honest take: KiCad is free and at least as capable. DipTrace makes sense only for specific users who tried both and prefer DipTrace.

OrCAD / Cadence Allegro

Enterprise-tier tools used by large hardware companies and ASIC houses. Expensive (tens of thousands per seat), powerful, with capabilities the others lack (complex multi-board systems, high-end signal integrity simulation, FPGA pin assignment integration).

If your job uses OrCAD, you know. Otherwise, ignore.

Migration paths

The most common migrations:

• Eagle to KiCad. KiCad has a built-in importer for Eagle's XML format. Symbols and footprints translate well; nets translate; 3D models often need rework.
• Altium to KiCad. Harder. Altium's file format is proprietary and the importer is not perfect. Plan to redraw schematics; floorplan and routing usually translate.
• EasyEDA to KiCad. EasyEDA can export Altium-format files which KiCad can import. Two-step lossy conversion.
• Anything to Altium. Easy commercially; just import. The pain is in your wallet.

Recommendation by use case

• Hobbyist or solo engineer: KiCad. No cost, no compromise.
• Startup hardware team: KiCad. Saves $20K+ on tooling for a 5-person team.
• Established hardware team with Altium investment: Stay on Altium. Migration cost exceeds benefit.
• Engineer also using Fusion 360 for mechanical: Fusion Electronics is reasonable for the integration; KiCad with FreeCAD as a less-integrated alternative.
• Quick prototype destined for JLCPCB: EasyEDA for speed; KiCad for portability.
• Large company with complex high-speed designs: OrCAD / Cadence for enterprise integration; Altium for general work.

Frequently Asked Questions

Has KiCad really caught up to Altium?

For 90% of design work, yes. The gap remaining is in advanced high-speed design (PCIe gen 5, DDR5 routing) and at-scale library management for teams with thousands of parts. For everything below that, KiCad is competitive.

Should I learn Altium for my career?Altium experience is valuable on a resume because most large hardware companies use it. KiCad experience is increasingly valuable as more startups and growing companies adopt it. Knowing both opens more doors; if forced to pick one, KiCad first because its skills transfer to Altium more easily than the reverse.

Why is Altium so expensive?Subscription model with limited competition at the high end. The price was set when KiCad was less capable; whether it remains defensible long-term is debated. Altium's value is in the complete ecosystem (libraries, vault, ECAD/MCAD integration, support contracts), not the design tool alone.

What about FreeCAD with KiCad-StepUp for 3D?Workable. KiCad has built-in 3D rendering; for serious 3D work (mechanical interference checking, custom enclosures), exporting STEP and using FreeCAD or Fusion 360 works well. Most KiCad users do this for any board going into a real product.

Is OrCAD worth learning if I might join a large company?If the company specifically uses OrCAD, yes. Otherwise, KiCad and Altium fluency cover most hardware roles. The OrCAD-specific skills do not transfer back; they are an investment in one stack.
