VPS With One-Click Apps: The Best Catalogue Isn't Your Host's

Two numbers frame this decision. DigitalOcean’s Marketplace lists 409 solutions, including a dedicated AI Agents category. Coolify’s self-hosted catalogue carries 280+ deployable services — and unlike a host marketplace, it runs on any KVM VPS you like and moves with you when you change provider.

Which points at the move most people should make: don’t choose a host for its app catalogue. Install a self-hosted PaaS — itself usually a one-click app — and get a comparably large catalogue that follows you to whichever provider you use next.

That said, host marketplaces still matter for the first install, and they differ in ways that count more than the app count they advertise.

Don’t rank marketplaces by app count

A marketplace with 100 apps is worse than one with 40 if the 100 are a 2015-vintage LAMP list. Three things actually separate them:

Does it cover modern self-hosted software? The useful test is whether the catalogue includes the things people actually self-host now — n8n, Coolify, Ollama, agent frameworks — rather than stopping at WordPress, Joomla, LAMP and phpMyAdmin. DigitalOcean’s Marketplace passes: it carries n8n, Coolify, and Ollama with Open WebUI as 1-Click Apps. Hostinger’s catalogue covers agent-era software including OpenClaw and n8n alongside Docker.

How stale are the packaged versions? A one-click image is a snapshot someone built at a point in time. If the maintainer hasn’t rebuilt it, you’re deploying an old version of the application and an old base OS with whatever unpatched vulnerabilities came with it. This is the single biggest risk in the category and the hardest thing to see from the outside.

Does the image ship hardened? Some images boot with a firewall enabled and credentials generated per-instance. Others come up with a service listening on all interfaces and a default password, meaning there’s a window between first boot and your first login where anyone scanning the internet can reach it.

We have not deployed and audited every image across these marketplaces, so this article doesn’t name specific images as insecure — doing that without testing would be irresponsible, and image contents change with every rebuild. What follows instead is the check you can run yourself in about ninety seconds, which is more reliable than anyone’s audit from six months ago.

Check any one-click image before you trust it

Run these immediately after the image finishes deploying, before you point a domain at it.

1. What’s listening, and on which interface?

sudo ss -tlnp

Look at the Local Address column. 127.0.0.1:8080 is bound to localhost and unreachable from outside. 0.0.0.0:8080 or *:8080 is exposed to the entire internet. If an admin panel is on that list and you haven’t set a password yet, you’re in a race.

2. Is the firewall actually on?

sudo ufw status          # Ubuntu/Debian
sudo firewall-cmd --state  # RHEL/Rocky

“inactive” means the only thing protecting the exposed ports above is obscurity.

3. How old is the software?

cat /etc/os-release           # base OS version
apt list --upgradable 2>/dev/null | wc -l   # pending security updates

A long upgradable list on a freshly-deployed image tells you exactly how stale the snapshot is. Run sudo apt update && sudo apt upgrade before anything else.

4. Are there default credentials?

Check the image’s documentation and the message-of-the-day on login. Well-built images generate a unique password per instance and print it once; weaker ones ship a documented default that every deployment shares. If you find a default, change it before you do anything else.

5. Lock it down before exposing it.

sudo ufw allow OpenSSH
sudo ufw enable

In that order — the reverse is the classic way to lock yourself out, as covered in our beginner VPS guide.

The providers

1. Hostinger — the least friction from click to running app

Hostinger’s one-click catalogue covers the software people are actually deploying in 2026 — OpenClaw, n8n, Docker and similar agent-era tooling — rather than a legacy CMS list. Its catalogue is smaller than DigitalOcean’s, and that isn’t the point: what it optimises is the distance between clicking deploy and having the thing running. Its VPS Docker Manager adds template-based container management from the panel, and the browser terminal means you can inspect what an image actually did without setting up SSH keys first.

Combined with 4GB at the entry tier and weekly backups included, it’s the lowest-friction route from “I want to run this app” to the app running. That’s what this keyword is actually about.

The caveats we’ve noted throughout apply: fewer vCPUs than equivalently-priced competitors, and the advertised rates need a long prepaid term.

2. DigitalOcean — the deepest marketplace

The DigitalOcean Marketplace is the largest and best-documented of the host-run catalogues — 409 solutions at the time of writing — and it passes the modern-software test comfortably. n8n, Coolify and Ollama with Open WebUI all ship as 1-Click Apps, each with its own documentation page describing what the image installs and how to configure it after boot. There’s a dedicated AI Agents category with 11 entries, and the front page currently features OpenClaw and Hermes Agent as Droplet 1-Click deployments, which is about as current as this category gets.

The category counts in the sidebar are the useful signal — and an AI Agents category with OpenClaw and Hermes Agent on the front page is not a 2015-era LAMP list.

That documentation is the real differentiator. Most marketplaces give you a button; DigitalOcean gives you a page explaining what the button did, which is what you need when something doesn’t work. Images are also versioned and rebuilt more visibly than most.

Backups remain off by default at 20–30% extra, which is worth enabling on anything you deploy this way.

3. Cloudways — the app is the unit

Cloudways inverts the model: rather than deploying a server and then installing an app, you deploy an application and Cloudways provisions the server underneath on DigitalOcean, AWS, Google Cloud, Vultr or Linode.

For WordPress, WooCommerce, Laravel and Magento this is the smoothest path available, with staging environments and backups built in. The catalogue is narrower than DigitalOcean’s and focused on web applications rather than self-hosted tooling — you won’t find agent frameworks here — and support covers the platform rather than your application.

4. ScalaHosting — SPanel with a bundled installer

ScalaHosting’s SPanel includes application installation alongside domain, email and database management, with WordPress and Joomla managers built in — and no per-account cPanel licence, which as our cPanel cost breakdown sets out is worth $330–840 a year on its own.

The catalogue skews toward traditional web applications rather than modern self-hosted tooling. If you’re deploying WordPress sites for clients, that’s the right catalogue; if you’re deploying an agent stack, it isn’t.

5. Railway — templates rather than images

Railway deploys from templates into a managed platform rather than giving you a server with software preinstalled. You never touch an OS, which means the staleness and hardening questions above largely don’t apply — the platform maintains the runtime.

The trade is control and cost model: it’s usage-based rather than a fixed monthly server, and you’re on a platform rather than a VPS. Right if you want to stop thinking about servers entirely; wrong if you specifically want root on a box.

6. Panel-level catalogues — Plesk and SolusVM

If your host gives you Plesk, you get its extension catalogue and Softaculous-style installers regardless of what the host itself curates. That’s a useful thing to know: the panel’s catalogue is often larger and better maintained than the host’s marketplace, and it’s the same catalogue on every host that ships that panel.

Plesk is available as an OS template or licence add-on from most of the hosts in this article, so the practical question is whether your chosen provider bundles the licence or bills it separately — the same question the cPanel cost breakdown works through.

The better answer: install a PaaS, get 280+ apps

For most people reading this, the highest-leverage move is one install.

Coolify is open source, self-hosted, and its catalogue now includes 280+ one-click deployable services — databases, workflow tools including n8n, AI inference engines including Ollama, monitoring, analytics, and most of the self-hosted software people actually run. Dokploy is the other leading option in the same category.

Two reasons this beats shopping for a host marketplace — and note that raw size isn’t one of them, because DigitalOcean’s 409 listings are comparable:

• It’s portable. The catalogue comes with Coolify, not with your provider. Move hosts and your entire deployment workflow moves intact — which matters given how often the cheapest provider changes, as our under-$5 comparison illustrates.
• It maintains itself. Services deploy as current containers with a redeploy path, rather than as a snapshot someone baked months ago. This addresses the staleness problem directly, and it’s the substantive advantage over any image-based marketplace.

The cost is that Coolify itself needs resources — its official 2GB minimum runs the panel and essentially nothing else, so 4GB is the realistic floor and builds are what push you past it. Our Coolify VPS guide sizes it properly, and our Docker VPS comparison covers the underlying requirements.

Conveniently, Coolify is itself a one-click app on both DigitalOcean’s Marketplace and most panel catalogues. So the sequence is: use your host’s marketplace exactly once, to install the thing that replaces it.

How we picked

We assessed marketplaces on whether they cover modern self-hosted software rather than on app count, using publicly listed catalogue contents read in August 2026. Coolify’s 280+ service figure and DigitalOcean’s n8n, Coolify and Ollama listings are from published sources.

We did not deploy images from each marketplace to audit their packaged versions or default security posture. That would require provisioning across every provider, and image contents change with each rebuild, so any such audit ages badly. That’s why this article gives you the five checks to run on your own instance instead of naming images we haven’t tested — and why you should treat any article that does name them without describing its method with some caution.

Most links here are affiliate links. Note that our central recommendation — install Coolify and stop caring about host marketplaces — makes the marketplace comparison largely moot, which is not the conclusion that maximises what we earn.

FAQ

What is a one-click app on a VPS?

A prebuilt server image with an application already installed and configured, so deploying it takes a few clicks instead of a shell session. The convenience is real, but the image is a snapshot — check what’s listening, whether the firewall is on, and how many security updates are pending before you trust it.

Are one-click installs safe?

They vary. Well-maintained images boot with a firewall enabled and per-instance credentials; weaker ones expose a service on all interfaces with a documented default password. Run sudo ss -tlnp and sudo ufw status immediately after deployment — that takes under a minute and tells you which kind you got.

Which VPS has the most one-click apps?

Among hosts, DigitalOcean’s Marketplace is the deepest and best documented. But the largest catalogue available to you isn’t a host’s at all — Coolify carries 280+ deployable services and runs on any KVM VPS, so installing it gives you a bigger catalogue than any provider offers.

Can I install one-click apps on any VPS?

Host marketplace images only work on that host. Self-hosted catalogues like Coolify’s work anywhere you can run Docker, which in practice means any KVM VPS — but not container-based virtualisation like OpenVZ, where Docker doesn’t run cleanly.

Do one-click apps update themselves?

Usually not. The image installs a version and then it’s yours to maintain. This is the main argument for a PaaS layer instead: Coolify deploys current containers and gives you a redeploy path, rather than leaving you on whatever version was baked into an image months ago.

Is one-click WordPress on a VPS better than managed WordPress hosting?

Different products. One-click WordPress on a VPS gives you root, full control and lower cost, and makes updates, backups and security your responsibility. Managed WordPress hosting costs more and hands most of that to someone else — though as our managed VPS comparison shows, even managed plans stop at your plugins and themes.
