Creating a client portal using open-source tools gives you full control over the features, customization, and how your portal is hosted.
Whether you’re a small business looking for a low-cost solution or a tech-savvy professional interested in a custom setup, open-source tools offer powerful options for building a client portal that meets your exact needs.
In this guide, we’ll walk you through the best open source software to use to create a self-hosted, open source client portal.
Setting up an open source client portal will be a little tricky though because there is currently no all-in-one open source client portal. However, there are plenty of options for each typical client portal use case, like file sharing, messaging, and e-signatures.
So our approach will be to give you the best open source software for each of those use cases, and you can combine them to create a modern self-hosted client portal.
If managing an open-source setup sounds like a bit too much, Foyer is a great alternative that offers all these features in a single, ready-to-use platform.
We even have a 14-day free trial (no credit card necessary), so it's easy to try out. Our pricing is affordable starting at just $19 per internal user per month.
For enterprises, you can even have Foyer hosted on your own Azure cloud environment (for more details contact our support team).
When creating a client portal, secure file sharing is crucial for exchanging documents and sensitive information.
Here are three of the best open-source tools for file-sharing that you can use to create a self-hosted client portal:
Nextcloud is one of the most popular open-source platforms for secure file sharing and collaboration. It provides a user-friendly interface with end-to-end encryption, granular user access controls, and seamless integration with other productivity tools. If you want a versatile solution that combines file sharing with additional features like calendar and contacts, Nextcloud is a great choice.

Open eSignForms is an open-source, web-based eSignature platform developed by Yozons, designed to handle legally binding electronic signatures securely. It allows users to create, send, and manage signed documents through a web interface without requiring additional plugins or software. Open eSignForms is highly customizable, making it a good fit for businesses needing tailored workflows and secure document handling.

Its integration with Nextcloud makes it a versatile choice for organizations seeking to add eSignature functionality to their client portals.
Key Features:
Creating a self-hosted client portal using open-source tools offers the best customization, data security, and functionality, but it can take a lot of work to set up.
To make it easier for you, I went through the steps of self hosting a client portal and created a guide.
Each section below shows how to set up one component of an open source client portal and shows the guides I used so you can follow along.
For secure file sharing, I used Nextcloud (just because I'm most familiar with it).
But like we outlined above, you could choose any other service like SeaFile or OwnCloud too.
Here's how I set it up:
For secure client messaging, I chose Rocket.Chat (again because I'm most familiar with it).
Here's how I set it up:
For eSignatures, I opted for LibreSign because it integrates so seamlessly with Nextcloud (that's what we used for file sharing).
Here's how I set it up:
While setting up all these open source tools can take a lot of time and effort, the result—a secure and customized client portal—is quite the reward.
Even with all these tools set up, the work has just begun. To keep your open source client portal secure, it's important to continuously manage and update each component.
With open source software, it's common for security vulnerabilities to be found, and contributors to push fixes and new versions.
However, as with all self-hosting, it's up to you to ensure you're up-to-date. This means being alert and proactive at seeing what updates are available, updating database versions, operating systems, migrating data, etc...
Having set up both an open source client portal, and cloud-based client portals I can speak to the pros and cons of both.
It comes as no surprise that the self-hosted client portal took a whole lot of work to create and maintain, but does that make it not worth it?
Let's get into some of the pros and cons.
With a self-hosted open-source setup, you gain full control over every detail of your client portal.
You can choose each feature, customize the design to match your exact needs, and manage all data on your own servers. This control is ideal if you need to create custom integrations for your business (or are working with very specific requirements).
Plus, after the initial setup, there are no monthly fees other than server costs, which can be appealing if you’re focused on long-term cost savings.
However, self-hosting requires a lot of time and technical skill.
Setting up each tool—from file sharing to messaging—involves installing software, configuring databases, and securing servers. Future updates, security patches, and troubleshooting are also your responsibility.
On top of that each tool may not work perfectly with others, which can lead to compatibility issues and extra time spent fixing them.
Overall, managing a self-hosted portal is a big commitment and can pull attention away from your main work.
But how does that compare to using a pre-made client portal in the cloud?
With cloud-based client portals, like Foyer, you get a fully managed, easy-to-use solution.
With cloud-based client portals, you don’t need to worry about complex setups and technical issues. It includes everything you need—file sharing, messaging, eSignatures, and more—all in one place.
A portal like Foyer is simple to start, and you don’t need special skills to get it running. It also takes care of all updates and security patches automatically, so you don’t have to manage any of that yourself. And if you need help, Foyer’s customer support team is available, so you’re not left to troubleshoot alone.
While Foyer has a monthly fee, this cost covers updates, security, and support—saving you time and money in the long run.
And if you're an enterprise, there are even options to host Foyer in your own Azure cloud.
Though it may not offer the advanced level of customization of a self-hosted portal, it provides plenty of options to tailor the portal to your brand.
If you have technical skills and want full control, a self-hosted solution could work well for you. But for most businesses, a cloud-based solution the better choice almost every time. Cloud-based client portals, like Foyer, allow you to focus on what matters most—serving your clients—without getting bogged down by the complexities of managing a bunch of self-hosted services.
Creating a self-hosted client portal with open-source tools gives you full control, but it comes with a lot of setbacks.
Setting up each tool, managing configurations, and keeping everything updated takes a lot of time and technical work. We explored multiple open-source options, and while they offer flexibility, they also mean you’re responsible for updates, security patches, and compatibility between tools.
For those who prefer a simpler solution, Foyer is a great alternative. With Foyer, you get a client portal that takes care of updates, security, and integration, so you don’t have to manage each part yourself. It’s an great choice if you’re looking for a fully-managed client portal without the technical overhead of self-hosting.
