The Products · TL;DR
1 min readTL;DR
The platform (dloizides.com) is not a single app — it's a collection of independent products that share one set of infrastructure. Each product is multi-tenant: many separate customer accounts ("tenants") live inside the same deployment, isolated from one another. The products are at different stages of maturity but all run on the same plumbing: authentication, storage, notifications, analytics, and a shared UI kit.
There are four families worth knowing:
| Product | What it does | Audience | Maturity |
|---|---|---|---|
| Erevna | Surveys & forms with many question types + validation + public/anonymous responses | Anyone collecting structured answers | ~65% complete (analytics is the next gap) |
| Katalogos | Online menus for restaurants/cafés (categories, items, variants, images, QR-ready public page) | Hospitality businesses | Billing-enforced, custom domains |
| Kefi | Event landing pages with RSVP and bring-your-own custom domains | Event organisers | Feature-complete |
| Games & tools | Standalone browser games (Aurora, Morphe, KeyboardPiano) and tools (Quotes) | General public | Standalone apps |
A useful mental model: Erevna, Katalogos, and Kefi are tenant-based SaaS products (you sign up, you own data, others can't see it). Games & tools are public browser apps that reuse the platform's deploy pipeline and shared libraries but don't carry a per-customer account model.
All three SaaS products are web-first React Native Web / PWA apps. They share a common UI kit and lean on the same platform services rather than each re-implementing auth, file storage, and so on.
