The short version

  • Only Playground AI 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.; Playground AI positioned more as a template-driven design app than a general-purpose image generator, limiting flexibility versus raw model access.
  • They diverge on capability: Cadence Allegro covers Constraint Manager, Playground AI covers Text-to-design generation.
  • 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.

Playground AI

  • Positioned more as a template-driven design app than a general-purpose image generator, limiting flexibility versus raw model access.
  • Advanced editing features are gated behind paid Pro and Pro Plus tiers.
  • No enterprise or team plan is listed on the public pricing page.

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.

Playground AI: What are Playground AI's free plan limits?

Free users can create up to 10 images every 3 hours, get 3 monthly generations across Nano Banana, GPT Image 2 and Seedream, and 2 downloads per day, with no upscaling or background removal.

Source
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.

Playground AI: How much do the paid plans cost?

Pro is $12/month billed annually ($15/month billed monthly) with 150 monthly credits, and Pro Plus is $36/month billed annually ($45/month billed monthly) with 1,000 monthly credits.

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.

Playground AI: How is usage metered on Playground AI?

Generations consume credits; Nano Banana Pro costs 4 credits per generation while all other models cost 1 credit per generation, with monthly credit pools varying by plan.

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.

Playground AI: How do I cancel or manage billing?

Users can update payment methods or cancel through the Billing Portal in the avatar menu; only credit and debit cards are accepted.

Source
Playground AI: Does Playground AI offer API access?

API access is available by application via a form, and is prioritized for partners generating over 1 million images per month.
