The short version

  • Only Inkscape has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cadence Allegro cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.; Inkscape no CMYK color mode support, making it unsuitable for professional print workflows requiring full color management
  • They diverge on capability: Cadence Allegro covers Constraint Manager, Inkscape covers Vector editing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cadence Allegro

  • Cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.
  • The learning curve is steep and the interface carries decades of accumulated convention, so a designer coming from another tool needs weeks to become productive and formal training is effectively mandatory.
  • Capability is split across product tiers and add-ons, so the feature you assumed was in Allegro may be an extra SKU, and the quoted configuration deserves a line-by-line check against your actual requirements.
  • Perpetual licences still carry annual maintenance to stay on current releases, and lapsing maintenance means paying to rejoin later, so the perpetual option is only cheaper over a long horizon.
  • Library and part data management is a project in its own right; teams that treat it as an afterthought end up with inconsistent footprints that surface as manufacturing defects rather than design errors.

Inkscape

  • No CMYK color mode support, making it unsuitable for professional print workflows requiring full color management
  • Lacks advanced features like 3D effects, Live Paint, and Live Trace found in Adobe Illustrator
  • Extension ecosystem is smaller and more fragmented than Illustrator's built-in advanced capabilities

Answered from the vendors’ own pages

Cadence Allegro: Can I still buy a perpetual Allegro licence?

Yes. Cadence channel partners quote both annual lease and perpetual licences for Allegro X, with perpetual starting around $18,000 including support. OrCAD X is more commonly sold as lease only.

Inkscape: Is Inkscape free and open source?

Yes, Inkscape is completely free and open source under the GPL license. There are no licensing fees or subscription costs.

Cadence Allegro: How does Allegro differ from OrCAD?

OrCAD X is schematic capture and mainstream PCB layout; Allegro X is the high-speed implementation environment with the full constraint manager. They share a database, so moving up does not mean redrawing.

Inkscape: What file formats does Inkscape support?

Inkscape's native format is SVG (Scalable Vector Graphics). It can import and export AI, EPS, PDF, PS, PNG, and many other formats.

Source
Cadence Allegro: Is there a free or student version?

Cadence offers time-limited evaluation and academic programmes, but there is no free commercial tier.

Inkscape: Can Inkscape be used for professional print design?

Inkscape lacks CMYK color mode, which is required for professional print work. Adobe Illustrator is better suited for print design due to superior color management and CMYK support.

Source
Cadence Allegro: Do I need Sigrity as well?

Only if you need signal or power integrity simulation. Allegro enforces constraints but does not simulate; Sigrity is a separate purchase.

Inkscape: What platforms does Inkscape run on?

Inkscape is available for Linux, macOS, and Windows. It runs on all major operating systems and is fully cross-platform.

Source
Inkscape: Does Inkscape have extensibility and plugins?

Yes, Inkscape has an extension system with community-built plugins. Extensions can be installed from the Extension Manager or downloaded manually, including tools for GCode generation, embroidery design (Inkstitch), and more.
