Low-code and no-code are the latest phenomena to take over our strategy meetings and development chats. These solutions are not new, but the emergence of new technologies and a shift in how we work has accelerated their need within the workplace.
The statistics below provide an overview of the scale of the low code market:
- Forrester states that as much as, 75% of application development uses low-code platforms.
- Gartner places worldwide low-code market growth at 23% in 2021
- According to the market research study published by P&S Intelligence, the global low code market will witness a 31.1% CAGR during 2020–2030 to reach $187.0 billion by 2030.
With every emerging market comes a plethora of new tools and several open source alternatives. Adopting an open source low code platform takes time and resources. Thankfully, we have gone through this pain for you. As creators of the fastest growing open source low code platform, we have tried and test over 50 other tools. We spent days gathering this knowledge and decided to share our thoughts with the world in the spirit of openness.
However, before we begin, let us make sure we are on the right page.
What is low-code?
Low-code is a visual approach to developing software using a low-code platform. While no-code development involves zero coding, low-code accepts minor coding as part of the build process. It is this balance of abstraction and flexibility that provides the user with a fast and extensible experience.
What is open source?
Open source is a term used to refer to something that can easily be accessed, inspected, modified, and shared. Therefore, the code behind open source software is publicly accessible—anyone can inspect, modify, and distribute the code.
The opposite of open source software is proprietary software. Proprietary software is often referred to as closed source. The primary difference between open source and proprietary software is that the user cannot see the code base and must agree to a license that prohibits them from doing anything to the software that the author has not permitted.
The pros and cons of an open source low code platform
Deciding between open-source and proprietary software can be a tricky decision. To help with this, we have listed the pros and cons of low-code open-source platforms.
Pros and cons of open source platforms
First up, let’s think about the benefits and downsides of open-source tools.
- Transparency: Often, with proprietary software, when we request a product change or support fix, we are given a ticket number and little other feedback. These requests often disappear into the abyss with zero to little knowledge of the progress. This lack of transparency is hard to handle when users rely on the requested change. With open source software, users can monitor the progress as the data, code, and software development process is open for all to see - in many cases, users can fix the problem themselves! This is critical for low-code, as the platforms must be flexible in nature, and in many cases, power mission critical functions across a company’s operations.
- Control: Companies choose open source because they have greater control and can change parts of the software to meet their needs. They can also examine the low-code platform to ensure it is not doing anything they do not want.
- Reliability: Proprietary software relies on a company updating, patching, and enhancing the codebase. Open standards and peer review ensure that open source code is tested accordingly and often.
- Flexibility: With open source software, users are not locked into using the code in any specific way. This is critical for low-code as there are a multitude of use cases and all businesses are unique. Flexibility is critical for unique businesses.
- Peer review: Because the source code is open and accessible by peer programmers, the code base is actively checked and enhanced, leading to a better product.
- No vendor lock-in: Freedom for the user means users can take the open source code anywhere and use it for anything, at any time.
- Community: Open source software often inspires a community of users and developers to form around it. This community often produces, tests, uses, promotes, and ultimately affects the software they love.
- Support: In some cases, open source software support is either - left to the community or only available at a cost.
- Orphan software: There is a chance community members move away from the project and officially “orphan” the software. This con is debatable. The counterargument is pretty straightforward - if a proprietary product’s company goes down, so will the product - and this is often the most likely of the two. With open source, the codebase and community live on after the original creating company leaves.
Low-code platforms: pros and cons
Similarly, once you’ve decided that you need to build your own solution, there’s also the calculation to be made as to how you’ll go about it. So why would you opt for a low-code platform over the alternatives, like no-code tools, or hard-coding?
To get a better grasp on this, let’s think about low-code’s pros and cons.
First up, let’s think of the pros of working with a low-code platform. There are as many reasons to use low-code tools as there are businesses using them. Here are some of the most common reasons that our users turn to low-code:
- Speed - For professional developers, the big appeal of low-code platforms is being able to quickly turn out effective software solutions. This is especially important for repetitive development tasks. Low-code tools are perfect for rapid application development.
- Cost - With reduced lead times come reduced costs. Your developers are highly skilled professionals, so their labor comes at a premium. Or, if you don’t have a development team, low-code can help you avoid having to pay to bring them on.
- Ease-of-use - Low-code platforms democratize development. These days, you don’t need years of experience and training to build effective custom apps.
- Consistency - Low-code platforms provide consistent experiences for developers and end-users alike.
- Integrability - When you hard-code solutions, you’ll need to make sure they work with the rest of your software stack. Low-code platforms tend to offer high levels of integrability, right out of the box.
- Reliability & support - When you build using low-code tools, you’ll enjoy a much greater degree of reliability and support than if you built the same tools from scratch.
Of course, we’re biased, and we think that low-code is the right choice for almost any business.
But are there downsides?
Well, sure. At least, there are situations where it might still be preferable to opt for a hard-code solution. Equally, there might be times when a no-code platform would be more suitable than a low-code one.
Here are the key takeaways:
- Unsupported functionality - If you need to do something very specific, you could have difficulty finding a low-code platform that supports the functionality you need within business processes. However, with increased flexibility and extensibility, this is becoming rarer and rarer.
- Learning curves - Of course, with any new tool, your team will actually need to learn how to use it. In most cases though, you’ll more than make this time back in efficiency savings. Still, no-code solutions can offer a faster initial onboarding process.
- Internal roll-out - In larger organizations, there’s also the issue of getting new tools signed off for internal roll-out.
- Internal resistance - You might come up against decision-makers who are skeptical of low-code development. They might think platforms are insecure, underpowered, or unreliable. All myths, of course, but you’ll need to be aware of these before you can dispel them.

How to choose an open-source low-code platform
So, we know that there are a range of different use cases for open-source, low-code platforms. We also know that within each of these, there’s an ever-growing number of options. So how are you supposed to choose the right one for your needs?
Of course, there’s no one-size-fits-all approach here.
For instance, the best solution for customer-facing mobile apps won’t necessarily be best for internal tools.
Instead, we need to think about the decision factors that you’ll need to consider when choosing between different tools. This cuts across technical and operational issues alike, so pay close attention.
Here we go.
Obviously, our top priority is figuring out how we’re going to make life better and easier for our end users. There are a whole bunch of different levels to this.
Amongst other considerations, we should ask ourselves the following questions:
- How many users will we have?
- What kind of actions will they need to take?
- Do different users need different levels of access?
- What is the general level of technical literacy?
- What kinds of devices do our users prefer?
- Where/what kind of people are our users?
These might seem like superficial questions, but they have a material impact on the features and functionality you’re going to need. For example, if you know different users will have different access needs, you’ll want to be able to implement RBAC.
It’s also vital to understand the kinds of users who will be building tools. Are they professional developers who want to make their lives easier, or are they ordinary business users, with no preexisting development experience?
This obviously has a huge impact on the types of tools that are going to offer you the most value.
In other words, do you need a platform to speed up normal developments or do you need one that empowers your team as citizen developers?
These things aren’t necessarily exclusive, of course.
All the same, when you’re scoping out open-source low-code platforms, it’s helpful to have a firm grasp of the exact way you expect your eventual choice to be used.
Hosting and deployment
And what about how we’ll host and deploy our end products?
You might have specific requirements here. Or, you might just want to go for whatever’s cheapest and easiest.
In any case, there are a few routes you can go down. These include:
- Cloud hosting.
- Private network infrastructure.
- Local devices.
- Hybrid approaches.
Again, what’s best here is highly dependent on your specific needs.
So for example, if you just need to get your tools out in front of as many users as quickly as possible, you’d probably want to go for cloud deployment.
On the other hand, if you have more specific security requirements, you’re more likely to opt for self-hosting.
Did we mention that Budibase supports both?
Cost is another obvious consideration when thinking about different open-source low-code platforms. As with any other type of digital transformation, we want to get the most benefit for the least outlay.
This can actually be trickier than you’d think.
One issue is that there’s not much consistency in the way vendors charge for their tools. One open-source low-code platform could look like good value on the surface but actually, come along with a raft of hidden costs down the line.
If you don’t realize this until a tool is embedded in your organization, you’re going to have a big problem.
Check out our pricing page to find out more about how we charge for Budibase.
Maybe it should go without saying that you’ll need to ensure that any platforms you’re considering will do what you need them to. Again it’s difficult to make generalizations here. Every use case is going to be unique.
For example, you might need to add a specific feature to the tools you plan to build with your open-source low-code platform.
So, say you wanted to build an app that allows your employees to share documents with each other. One of the very first things you’d need to confirm is that your platform can support file attachments.
Of course, this is an overly simplistic example.
All the same, we could apply the same logic to any specific feature or functionality you require. As such, it’s vitally important that you have a clear idea of what you want to build before you start considering specific low-code platforms.

Data and integrations
Finally, we need to think about how different low-code platforms are going to interact with your existing tools and data.
There are two things we need to consider:
- External data support.
- Third-party tool integrations.
There’s a certain amount of overlap here, of course.
Let’s take external data support first. There’s a good chance you’re comparing open-source low-code platforms because you have a data set that you need to build a tool to manage. So, any specific platform you choose will need to support the types of data you want to use.
Then we have integrations with external tools.
Most often, this means that we want to use our low-code platform to trigger events in third-party apps, or vice-versa. Nowadays, this mostly works by offering support for integration tools, which act as sort of intermediaries between platforms.
Take a look at our integrations page for more details on connecting Budibase to your wider software stack.
