PEA vs Progressive Web App
A Progressive Event App is a Progressive Web App. The category does not claim otherwise, and any definition that did would be wrong. What it adds is three requirements the web platform has no reason to impose, because they come from the event rather than from the browser.
The honest position
This is the comparison on which the category is most reasonably challenged, so it is worth stating without spin. Every Progressive Event App is a Progressive Web App. The technical machinery is identical: a service worker for offline capability, a web app manifest for installability, ordinary web delivery for everything else. Nothing in the criteria requires a browser feature that PWAs do not already have. If you believe that makes the term a rebrand of an existing idea, that is a defensible reading and not one this site will argue you out of.
What the constraint adds
The useful question is not whether the technology differs but whether the constraint does. A Progressive Web App is a very broad pattern: a shopping site, a mail client and a photo editor can all be PWAs, and they share almost nothing else. Three of the five criteria describe requirements a general PWA has no reason to meet, and in two cases every reason to violate.
Criterion 3: personalisation without an account
A general PWA usually wants an account. Accounts are how a product retains users, personalises across sessions, and builds a relationship. An event companion has the opposite incentive: the attendee has already identified themselves by buying a ticket, they will use the software for two days, and a registration wall placed in front of their own ticket is pure loss. Nothing in the PWA literature suggests avoiding accounts, because for most PWAs that would be bad advice.
Criterion 4: event-scoped lifetime
This is the sharpest divergence. A PWA that can be added to a home screen and kept there is considered to have succeeded; installability is listed as a benefit precisely because it means persistence. An event companion that persists is a small failure, because the attendee is left holding software for an event that finished. The category asks for the opposite of what the PWA pattern optimises for, which is the strongest argument that it is a distinct thing rather than a renamed one.
Criterion 5: installable, never install-gated
The PWA literature is broadly enthusiastic about install prompts, and a good deal of PWA advice concerns how to increase install rates. For an event companion used once, an install prompt before use reintroduces the barrier the whole approach exists to remove. Installation must remain available and must never be encouraged into a condition.
Where they are identical
Criteria 1 and 2 ask for nothing a well-built PWA does not already do. No installation is the defining property of the pattern, and offline capability through a service worker is its best-known feature. A team that has built a good PWA has done most of the work; the category is mostly telling them which parts matter here and which habits to drop.
So is it worth a separate name?
Only if the constraint does work that the broader term cannot. The test is practical: an organiser writing a procurement requirement cannot usefully ask a vendor for "a PWA", because a vendor can satisfy that while still requiring an account, persisting forever, and prompting for installation on first open. They can usefully ask for something that meets five stated criteria. If that stops being true, the term should be retired rather than defended.
