portchecker.io Hosting Live In 5 Minutes

portchecker.io hosting on xCloud lets you deploy portchecker.io, an open-source TCP port checker with a web UI and a REST API, on your own domain. xCloud runs the pinned web and API images, publishes only the web port over HTTPS and sets private-address checks to off. There is no login, so anyone with the address can run checks from your server's IP, which you may want to restrict.

What is portchecker.io?

portchecker.io is an open-source TCP port checker that tests whether a port is available on a given hostname or IP address. It has a static web UI, a REST API built with Litestar and interactive API documentation, and a Prometheus metrics endpoint for response times and status codes. A self-hosted portchecker.io is a TCP port checker on your own domain, in place of public port checker websites. It is licensed GPL-3.0.

On xCloud it is portchecker.io 4.1.0, with the official web and API images pinned by digest, and only the web port published over HTTPS. It stores nothing, so there is no volume. ALLOW_PRIVATE is false, which refuses private IPv4 addresses typed in directly. Each check opens an outbound TCP connection from your server's IP, and there is no login or rate limit.

From Sign-Up to a Live Port Checker In Just 3 Easy Steps

Self-hosting a port-checking tool normally means two containers, a private network between them, a domain and a certificate before a single check runs. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick portchecker.io from the OneClick catalog. Choose a domain — there are no accounts or secrets to set.
Step 02
We Deploy It For You
One click. We bring up the official portcheckerio-web and portcheckerio-api images pinned by immutable digest, keep the API on the private container network, and publish the web service over HTTPS on your domain.
Step 03
Check A Port
Open your HTTPS portchecker.io URL — no sign-in needed. The host box is pre-filled with your own IP address; enter a hostname or address and one or more ports, then select Check Ports.

Everything portchecker.io Does, On Your Own Server

portchecker.io runs in full here — the same browser tool and REST API as the public service, from your own server's network vantage point.

Check Several Ports At Once
Check one or several TCP ports on a hostname or public IPv4 address in one request, with quick buttons for HTTP, HTTPS, SSH, FTP, MySQL and PostgreSQL.
Validate Firewall Changes
See from outside whether a port really is reachable after a firewall-rule change.
A Documented REST API
Automate checks through POST /api/query and GET /api/<host>/<port>, with interactive API docs at /docs.
Your IP, Pre-Filled
The host box is pre-filled with the visitor's own IP address, so checking your own open ports takes one click.
Prometheus Metrics
Monitor the tool itself with Prometheus metrics exposed at /metrics.
Stateless By Design
Nothing to back up — a restart returns the exact same working tool, with no data to lose.

What You Can Do With portchecker.io

Check that a port is reachable from outside
Enter your public IP and a port to see whether a firewall or port forward lets traffic in, testing from your server rather than from a third-party website.
Test a service after a firewall change
Confirm that SSH, a web server or a game server port opens after you change rules, with the answer coming from a machine outside your own network.
Give your team a shared diagnostic page
Pre-fill a default host and port and share one address, so colleagues check a port without installing a client or sending the target to an unknown site.
Script port checks through an API
Call the REST API from a script or monitor and read the Prometheus metrics endpoint, so checks can run on a schedule and feed a dashboard.

portchecker.io vs Alternatives

Public port checker websites: A self-hosted portchecker.io runs the check from your own server, on your own domain, with an API you can script.
Uptime Kuma: Uptime Kuma has its own OneClick page. In a portchecker.io vs Uptime Kuma comparison, portchecker.io answers a one-off question about a single TCP port, on demand, from a browser or the API.
Gatus: Gatus has its own OneClick page. portchecker.io is a small stateless tool with a browser page and REST API for checking one port on demand, with no configuration file.
SmokePing: SmokePing has its own OneClick page. portchecker.io checks on demand whether a TCP port accepts a connection, with no history or graphs to keep.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

How much RAM does portchecker.io need?

The template floor is 256 MB of RAM, 1 CPU core and 2 GB of disk. It is a static page plus a small API, with no database, so the 6 GB plan is far more than needed and leaves room for other apps.

Can you self-host portchecker.io with Docker?

Yes. This template covers portchecker.io docker hosting end to end: web and API images pinned by digest, only the web port published, and HTTPS, with no volume or database to look after.

Does portchecker.io have an API?

Yes. Upstream provides a REST API built with Litestar, with interactive documentation at /docs on your domain, plus a Prometheus metrics endpoint at /metrics. The web page uses the same API.

Can portchecker.io check private addresses?

Not by default. ALLOW_PRIVATE is false, so private IPv4 addresses typed in directly are refused. The rule does not cover hostnames: a name that resolves to a private or loopback address, such as localhost, can still be probed.

Is it safe to leave portchecker.io public?

Only with care. There is no login and no rate limiting, and every check opens a TCP connection from your server's IP, so a public instance can be used to scan other hosts and attract abuse reports. Add Basic Auth to keep it private.

Is portchecker.io free?

Yes. portchecker.io is GPL-3.0 software with no charge for the code. The Cloud VPS is the only cost, so this portchecker.io cloud install runs every check from your own server address.

Does portchecker.io need a backup?

No. It is stateless: there is no volume, no database and no accounts, so a restart or redeploy returns the same working page. Keep a note of any DEFAULT_HOST or DEFAULT_PORT values you set in the Environment editor.

How do I upgrade portchecker.io?

portchecker.io stays on its pinned 4.1.0 images until a newer template version is adopted. Check the upstream release notes first. With no data to lose, redeploying is low risk, and nothing upgrades automatically.

Is portchecker.io an alternative to public port checker websites?

For checking a TCP port, yes. Upstream offers an open-source checker with a web UI and REST API, and running your own means the check comes from your server and the target address is not sent to a third-party site.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
