A flat-priced home for your always-on apps
Scalingo is a well regarded European PaaS with a genuine data-residency story. Ruust takes a different bet: one flat price per Egg per month in GBP, egress that is never metered, and every app kept warm around the clock. If you run lots of small, always-on services, predictability is the point.
Flat price per Egg, in GBP · unmetered egress · no cold starts
Both platforms let you push a git repo and get a running app with a managed database and TLS. The difference is how you pay and how your apps behave when nobody is looking. Here is where Ruust and Scalingo diverge, laid out plainly.
| Ruust | Scalingo | |
|---|---|---|
| Pricing model | Flat price per Egg, per month, in GBP. Same everywhere. | Plan and resource based, usually billed in EUR. |
| What a running app costs | Nano £3, Small £6, Standard £12, Large £24. No surprises. | Tends to depend on the container size and add-ons you choose. |
| Egress / bandwidth | Unmetered on every tier. No egress bill, ever. | Bandwidth usually factors into a resource-based bill. |
| Cold starts | None. Every Egg is kept warm 24/7, no spin-up lag. | Managed app platform; behaviour depends on your plan and setup. |
| Currency | GBP throughout. Handy if you invoice in pounds. | Typically priced and billed in EUR. |
| Data residency | eu-west (London) and us-east (Virginia) live; Frankfurt, Singapore coming. | Strong EU residency story with EU-based data centres. |
| Databases | Managed Postgres and Redis Eggs, private to your Coop, plus external by connection string. | Managed databases and an add-on ecosystem, a long-standing strength. |
| Bring your own host | Open-source Apache-2.0 agent, pull based; pay for the panel, not the metal. | Managed platform on their own infrastructure. |

What you get by switching.
One price, in pounds, that does not move
A Standard Egg is £12 a month, in every region, whether it serves ten requests or ten million. Nano is £3, Small £6, Large £24, and custom sizes run on a slider at £12 per vCPU plus £6 per GB. You can read your bill before the month starts, which is rarely true of resource-metered plans.
Unmetered egress, so traffic is never a tax
Egress is unmetered on every tier, full stop. A busy month costs the same as a quiet one. Fair-use rate caps exist to stop abuse, but there is no meter and no volume cap on the bandwidth you serve, so a spike never turns into a bill.
Always-on, with no cold starts
Every Egg is kept warm 24 hours a day. There is no scale-to-zero and no spin-up lag, so the first visitor after a quiet spell gets the same response as the hundredth. For small always-on apps, that steadiness is the whole point.
Live in about two minutes
Connect a repo, let Nixpacks autobuild (or bring your own Dockerfile), pick a region and size, and you are on HTTPS in roughly two minutes with TLS issued in about 90 seconds and renewed automatically. Databases, private networking in a Coop, health checks and zero-downtime rolling deploys come as standard.
Where Scalingo is the better fit.
A serious European data-residency story
Scalingo is a French PaaS built around GDPR and EU data residency, with EU-based data centres and a compliance posture that many European teams need on paper. If keeping data inside specific EU jurisdictions is a hard requirement today, that maturity is a real advantage and worth weighing carefully.
A settled, well supported platform
Scalingo has been running managed apps and databases for European customers for years, with an established add-on ecosystem and support that teams tend to speak well of. If you want a proven, batteries-included PaaS from a company with a long track record, it is a sensible choice.
EUR-native billing and European support
If your business runs in euros and you would rather deal with a European provider in your own currency and time zone, Scalingo fits that shape naturally. Ruust prices in GBP, which is a plus for UK teams but an extra conversion for everyone else.
Ruust vs Scalingo, the common questions.
Is Ruust cheaper than Scalingo?
It depends on your workload, and we will not quote Scalingo's prices for you since their model is resource and plan based. What Ruust offers is predictability: a flat GBP price per Egg (Nano £3, Small £6, Standard £12, Large £24) with unmetered egress, so the bill is the same whether the month is busy or quiet.
Does Ruust meter bandwidth like most platforms?
No. Egress is unmetered on every single tier, and there is no egress bill at any point. Per-Egg fair-use rate caps exist purely to stop abuse, but there is no metering and no volume cap on the traffic you serve.
Do apps on Ruust go to sleep when idle?
No. Every Egg is kept warm 24/7, so there are no cold starts, no scale-to-zero and no spin-up lag. The first request after a quiet period is served just as quickly as any other.
Can I keep my data in Europe on Ruust?
Yes. Ruust runs an eu-west region in London today, with Frankfurt on the way, and regions are independent cells so an Egg lives in one region. That said, if you have strict, specific EU jurisdiction requirements right now, Scalingo's established EU residency story may suit you better, so check your compliance needs against both.
