Questions & Answers

As answered by people managing Postmark and EventSheets.

What makes your product unique?

EventSheets's answer:

EventSheets is the only academic event platform whose interface is natively Arabic — right-to-left throughout, Hijri and Gregorian dates side by side, and an Arabic search that finds a word however it is spelled — while speaking English just as fully. Every certificate it issues carries a verification code, so a certificate can be checked by anyone holding it. Publishing an event is free; only the management services are paid.

Why should a person choose your product over its competitors?

EventSheets's answer:

The conference tools organisers know are built in English, for English — and an Arabic conference run on them ends up with mangled names, Latin-only certificates and a registration page the attendees cannot read. EventSheets was built the other way round. It also runs the whole event, not one part of it: registration, submissions and blind refereeing, sessions and committees, printed table cards and badges at their true sizes, QR check-in, and certificates — so an organiser does not stitch four tools together.

How would you describe the primary audience of your product?

EventSheets's answer:

Universities, research centres, scholarly societies and training bodies in the Arab world that hold conferences, seminars, workshops and courses — and the researchers who attend them, submit papers to them, and keep the certificates they earn.

What's the story behind your product?

EventSheets's answer:

It began in 2016 as a place to announce academic events in the Arab world, and the archive from those years still holds hundreds of them. What kept coming back from organisers was the same complaint: the announcement was the easy part. Registering attendees, receiving papers, sending them to referees, building the programme, printing the cards and issuing the certificates were all done by email and spreadsheets. So the site was rebuilt around that work rather than around the announcement — and it now runs an event from its first day to its last.

Which are the primary technologies used for building your product?

EventSheets's answer:

PHP 8.3 and Laravel 12, MySQL 8, Apache, deployed in Docker containers. Certificates are rendered server-side with JasperReports on the JVM. The site is a progressive web app — it installs on a phone without an app store.
