The short version

  • Each has a real cost: Altium 365 the 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.; Cadence Allegro cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on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.
  • They diverge on capability: Altium 365 covers Shared workspace, Cadence Allegro covers Constraint Manager.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Altium 365

  • A hardware startup where two engineers draw boards but eight people need to review them, avoiding eight CAD seatsnot Cadence Allegro
  • A team handing fabrication and assembly data to a contract manufacturer as a versioned release rather than a zip of Gerbersnot Cadence Allegro
  • A company running board and enclosure design in parallel and needing bidirectional geometry exchange with mechanical CADnot Cadence Allegro
  • A buyer checking component lifecycle and availability against the live BOM before a design is frozennot Cadence Allegro

Cadence Allegro

  • Routing a DDR5 or high-speed SerDes board where length matching and impedance rules must be enforced during layout, not checked afterwardsnot Altium 365
  • A rigid-flex design with multiple stackups that a general-purpose PCB tool cannot represent correctlynot Altium 365
  • A team of PCB designers working concurrently on partitions of one large backplanenot Altium 365
  • An organisation that already runs Sigrity or Clarity analysis and wants the layout constraints and the simulation to share one rule setnot Altium 365

Where each one falls short

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

Altium 365

  • The 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.
  • Add-on portals are expensive per seat; BOM Portal has been quoted at around 1,999 US dollars per user per year and MCAD CoDesigner at around 499, so the real cost of a working configuration is well above the headline.
  • It is tied to Altium Designer; there is no meaningful use of the platform for teams designing in KiCad, OrCAD or Allegro, which makes it a lock-in decision rather than a tooling one.
  • Renesas acquired Altium in 2024, and a semiconductor manufacturer owning the design tool used to select competing semiconductors is a conflict some buyers will want addressed in writing before uploading a library.
  • Repeated repackaging, from Altium 365 Standard and Pro tiers to Altium Develop and Agile Teams, has made renewal comparisons difficult and customers have found their previous tier no longer maps to anything on the price list.

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.

Answered from the vendors’ own pages

Altium 365: Is Altium 365 free with Altium Designer?

A workspace is included with a current subscription, but the higher tiers, extra authors and the add-on portals are chargeable. The unlimited non-author users are genuinely included.

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.

Altium 365: What does it cost?

Altium Develop starts at about 1,990 US dollars a year for one author plus a workspace, with extra authors at 995 US dollars each up to four more. Larger teams are quoted.

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.

Altium 365: Who owns Altium now?

Renesas Electronics completed its acquisition of Altium in 2024. Altium 365 is therefore a Renesas-owned platform.

Cadence Allegro: Is there a free or student version?

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

Altium 365: Can I keep design data on my own servers?

Yes, through the Enterprise on-premise workspace server, but that is a quoted product and most of the newer portal features assume the hosted platform.

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.
