Pay-per-use pricing punishes success. The more players love your game, the more you pay. That's backwards.

Frequently Asked Questions
Get answers to common questions about horizOn
Our customers shouldn't worry about storage optimization or compression. We've carefully designed packages based on extensive studies and analyses to give you the best experience without the complexity.
To offer our customers the best possible price, horizOn needs a strong foundation. We're scaling slowly and deliberately to ensure reliability and quality for all users. Capacity is constantly expanding.
horizOn is designed for smaller developers without a large budget who want good server infrastructure. Our competitors have strong infrastructure, but their costs are unpredictable. With horizOn, you get a clear dashboard, easy setup, a free tier to start, and fixed costs you can plan around.
horizOn is optimized for indie games, casual games, and medium-sized projects. It's not designed for real-time multiplayer games requiring sub-100ms latency or AAA titles with millions of concurrent users. For turn-based games, leaderboards, cloud saves, and backend services, horizOn is an excellent choice.
horizOn is actively used by ProjectMakers for multiple internal and client projects, so the backend runs regardless of paying customers. ProjectMakers is an established agency, not a single-product startup: horizOn is one of several products, and the infrastructure is funded by the broader business. In the worst case, both horizOn-Server and horizOn-simpleServer are available as self-hostable alternatives, so there is no vendor lock-in and your data remains fully portable.

Vom Testprojekt zur festen Backend-Strategie – horizOn überzeugt. Ich habe horizon.pm zunächst für ein kleines Testprojekt genutzt: eine browserbasierte Einkaufsliste mit Login, Cloud-Sync und Sharing. Ich wollte sehen, wie es sich im Alltag schlägt. Das Ergebnis? Ich bin begeistert! Kein Server-Setup, keine Datenbank, keine Infrastruktur. API-Key einfügen, Endpunkte nutzen, fertig. Meine App bestand aus einer einzigen HTML-Datei und hatte trotzdem User-Management und persistente Cloud-Speicherung. Die API ist klar, logisch und entwicklerfreundlich. Signup, Signin, Cloud Save, alles funktioniert genau wie erwartet. Besonders stark: Das einfache Cloud-Save-System per POST mit userId und JSON-Daten. Aus dem Testprojekt wurde eine Entscheidung: Künftig setze ich bei Spielen und Business-Anwendungen auf horizon.pm. Preis/Leistung ist unschlagbar, und die gesparte Entwicklungszeit enorm.
Read moreI had the pleasure to test Horizon, and I was genuinely impressed. The dashboard gives you a clear organized overview of everything you need unlike Firebase, where things can get a bit chaotic. With Horizon, you instantly have a good overview. What really sold me was how easy the integration was. As someone who doesn't enjoy backend development, Horizon was a game changer. It allowed me to skip the backend work entirely and focus on what I actually love building. Highly recommended for anyone who wants a cleaner alternative.
Read moreI switched because the bill never moves. A flat monthly price means I can plan my whole year without sweating a sudden traffic spike.
The Unity SDK was wired up in about two minutes. Leaderboards and cloud saves just worked, and I got back to building my actual game.
We needed players in three regions without surprise egress fees. Multi-region was already part of the plan we picked, no add-ons, no math.
What sold me was the honesty. The pricing page tells you exactly what you pay, and that is still the number on my invoice months later.
I dropped it into a Godot prototype over a coffee break. The REST endpoints are clean enough that I barely touched the docs.
Remote config let me tune balance without shipping a build. Support answered my odd question the same day, no canned reply.
As a side project I cannot afford a bill that scales with luck. A fixed price means a good launch week is just good news, not a panic.
