Interview with Martin McKeaveney

Co-Founder, Budibase - Open source low-code platform.

What is Budibase? Why did you build it?

Budibase is an open source, low-code platform for building business applications and internal tools. We make it easy and fast for developers and IT professionals to create their own software, by providing a visual app building experience with three main pillars: data, design, and automation.

The data aspect is where you can configure your data sources like Postgres, MongoDB, MySQL, Amazon S3, CouchDB, Airtable, REST APIs, and more. We even have our own internal database, so you can create apps from scratch with your own data. You can write custom queries against these databases, or you can have Budibase automatically generate and map from your database schemas and generate the queries for you. You can also convert your existing database into a fully functioning web application with just a few clicks. The data UI is also responsible for authorization and role based access management.

The design part is the UI of your application, where you create screens to display and visualize your data and perform CRUD operations on it, as well as editing colors,themes and other visual aspects.

The automate part is the brains of a Budibase app. From here, you can set up workflows and model business processes like approval workflows, onboarding flows, or more simply for sending Slack or Discord notifications.

My co-founders and I have built many internal applications and business apps in our careers, and we realize that it’s something that’s not only expensive, but not the best use of developer time, and it’s not really the most fun part of software development.

Companies often use a hodgepodge of different SaaS products, pay for expensive subscription support contracts, and generally hack around the tools and their APIs to get them to work together. Often they are trying to implement that little edge case that it just doesn’t do well.

We set out to create a large ecosystem that allows people to create these tools themselves in a much more efficient manner. Compared to other platforms, we wanted Budibase to be as accessible and open as possible, with a real focus on user experience and ease of use, which is why it’s open source and self-hostable, in addition to our cloud-based solution.

We like to say Budibase is simple by default, but very powerful and extensible as well, if you want to go down that path. Budibase dramatically reduces the time it takes to build full-stack web applications. Being able to create well-designed, responsive, secure, and performant web applications in record time is what Budibase is all about.

We envision a world where full-stack development is more democratized, and users can create their own software to solve their problems. There’s no longer a bottleneck on dev teams to create every piece of software for the whole org. Code is optional in Budibase, but engineers who know how to code can use it to speed up their workflows, so they can focus on the hardest engineering problems.

How do you think about that trade-off you mentioned around speed vs supporting advanced development needs?

Modeling the most common workflows is important. Like setting up your data sources, pulling the schema, your tables, that sort of grunt work that every developer does when they’re building an application.

They write a bunch of APIs and endpoints that they’ve done hundreds of times, and then you can get into that specific business logic. It’s automating those things that everybody has to do, and making them super simple, and then allowing code and more extensible parts to model business logic and custom pieces of functionality. Sometimes it’s almost easier to represent certain pieces of logic with a line of code than it is to have a whole bunch of wizards and modals to do it. Striking that balance is important, but we think we do it quite well.

What does a “day in the life” look like for you?

My morning generally starts with a cup of coffee, planning the day, responding to emails and having a look at the product board to see where we’re at in the current iteration with our work items.

After that, I generally try to spend mornings doing deeper work like programming or writing product specs. Right now, a lot of my focus is on DevOps, product management, and architecture work. I don’t really have as much time for purely programming or feature work, so I spend most of my time trying to unblock the team, working with them to architect new features for upcoming iterations. I’ll spend quite a bit of time talking with my co-founders around company strategy and direction. In the afternoons, I prefer to have meetings and spend time doing code reviews or product roadmap planning.

What is the team structure around Budibase?

The company is split into three sections or pillars: business, growth, and product. I lead product, which includes engineering. The engineering team is remote. There are six engineers who work across front-end, back end, DevOps, and QA. We run regular one-to-ones and monthly release cycles. Everyone has a good amount of autonomy in Budibase and is empowered to ship code to production on a regular basis.

As a remote team, we like to have a culture of writing, so things aren’t lost and they can be communicated effectively amongst the team. We’re growing at the moment and are recruiting engineers and other positions, and we hope to double or more over the next year.

How do you think about the balance between the open source code base and your cloud product?

The whole team works on the Open Source product, and the code base is shared between the two. We do have things in there, like conditionals for certain things that are in the cloud product, but there’s not really any features that are enabled on the cloud side that you can’t do in the self-hosted version. The only difference is, some of the ones in the self-hosted solution, you’d need to configure yourself, like sending emails, for example.

The way we think about it is if something’s going to be widely useful for the whole community, that’ll be part of the open source product. Right now, we don’t have any closed source code in Budibase. The plan is that in the future for larger organizations and more team-based ororganization-based structures, we’ll have features that will be part of an open core model, so they’ll pay for a certain plan and they’ll get those features on top.

With the cloud product, the same thing applies to subscription-based members. They can pay to get certain features in the cloud. The way we like to think about it is, for more scale-related features, those are the things that’ll be in the closed source product, but the features that are going to be useful to the wider community and smaller deployments, in general, will mainly go into the open source product.

How did you first get into software development?

I’ve been interested in computers from a young age, originally for things like gaming and media, where I used to play around with mods for my PC games and rooting games consoles, and things like that. I had my first foray into programming when the first iPod touch came out. I became fascinated with jailbreaking these devices, and eventually, I was doing a lot of iOS stuff for my friends. To begin this was working with UI-based tools that just did it for you, and then eventually editing Homebrew apps and writing very basic scripts and config files and automations in Objective-C and PowerShell.

At the time, I didn’t really even know I was programming. I was just trying to get things to work and changing variables around, so I didn’t have to keep doing things manually.

At my local college and then university, I had exposure to some basic C#, Java, SQL, but my first real dev internship was when everything really clicked for me. I built web applications there, but during that time, I became obsessed with learning lots of different programming languages and tools. I picked up Java, JavaScript, Ruby, Python, and some more functional languages, like Haskell, just for fun. I always enjoyed the different rules and paradigms of each language and learning different styles of programming. I finally decided to go deep on JavaScript, due to the fact it was so versatile.

Later, I got into Linux and worked a lot with infrastructure and automation tools as well, mainly on AWS. I loved the automation of infrastructure, and with tools like Terraform and CloudFormation. This was a whole new world for me. I thought it was awesome how you could just represent infrastructure as code. I always really liked the idea of working across the stack, and never really wanted to be siloed in the front-end, back end, or DevOps. I always enjoyed doing it all.

What is the most interesting development challenge you’ve faced working on Budibase?

Working on Budibase is a very interesting development challenge, given the fact that we’re building an app that builds apps. We have to think about things not only from the standpoint of the visual builder itself, but in the output, the generated app that Budibase creates, the builder creates JSON that gets stored in the database, and then gets converted directly into a fully functional web application at runtime.

It’s important for us to maintain backwards compatibility while shipping new features, and provide smooth upgrade paths for old applications to use new Budibase features.

Budibase connects to a ton of different data sources. As I mentioned, you can write queries for them, but with the ability to generate tables in Budibase that are directly derived from SQL schemas, and handle all the CRUD operations in Budibase apps, so you don’t have to write any queries yourself. Making this as seamless as possible for the user, was a real challenge. By building our own mini ORM over the top of Postgres, MySQL, Microsoft SQL Server, and Oracle, that can be controlled completely visually.

On the subject of databases, one of the other really big ones was our in-built database, that’s built on top of Apache CouchDB. We faced some serious challenges trying to make it as simple as possible to use, introducing schemas, relationships, and creating all the different data types that Budibase supports.

The awesome thing, in the end, was that it makes Budibase apps super portable and easy to replicate, to other databases. For example, you can create full Budibase apps from templates that we’ve created in one click, including a pre-seeded database. An employee application tracker is one of our templates. You click that and it just opens it in the builder, with data and everything. That’s quite hard to do with an external database because we can’t rely on your database credentials or your database schema. If we shift all that with the app, then you can get started straight away and maybe add your own data after.

The scope of a tool like this is very broad. We’re constantly facing challenging engineering problems that allow people to do things visually that you would generally perform by writing code. As with any visual software experience or software development experience, we’re constantly debating between customizability and ease of use. How do we make it visually simple, but powerful enough to be extended or configured through snippets of code?

What is the Budibase tech stack?

We’re pretty much a full JavaScript house. The whole back end is written with Node and Koa, and our whole front end is written in Svelte.js, which we really love. The back end for app metadata, as well as the internal DB, is all running on CouchDB. Our cloud platform is all run inside AWS, and the production platform uses Kubernetes for management.

What interesting projects are you playing around with at the moment?

In terms of Budibase, our production infrastructure’s all based on Kubernetes and managed with Helm. It’s been cool to use that to create scalable infrastructure and use all the tools surrounding the Kubernetes ecosystem. The team at Budibase has a lab day, once a month, where the team gets to work on whatever they want. Lab days can be for anything, but generally, it manifests itself in experiments of what’s possible with Budibase. There’s been some really amazing things built over the course of lab days, and some of them even get shipped.

The scope of a tool like Budibase allows for a lot of possibilities. Some examples are a full database editor that allows you to modify SQL schemas in Budibase, a text editing experience that allows you to edit the text in the DOM, kind of like Google Docs, a Google Sheets integration, and cURL and Swagger importers that just create REST data sources in Budibase by pasting those things or point into a definition.

More personally, I’ve been diving into some stuff around the Ethereum blockchain, and building little side projects for creating tokens and minting NFTs, just to understand how these things work under the hood. I don’t feel strongly about crypto either way, but it’s cool to play with new tools and a different way of programming, thinking about things in a different way.

3D modeling and WebGL also blow my mind. Some of the visual experiences that can be created in the browser are incredible.

Describe your computer hardware setup

I’m using a 15” MacBook Pro at the moment, but I have a new one waiting for me at home, which I’m looking forward to getting. I have Bose Quietcomfort headphones that are essential for focus, a 27”, 144Hz BenQ monitor, and a Filco Majestouch keyboard that’s been likened to a drum kit by the team, because it’s very loud.

Describe your computer software setup

OS: macOS Catalina.

Browser: Firefox.

Email: Spark.

Chat: Discord.

IDE: VS Code.

Source control: Git.

Describe your desk setup

When I’m traveling around, mainly in Spain and Portugal, I usually spend a few months in each place and just work mainly from my laptop, with no monitors. At home. I’ve got a monitor and a Herman Miller Aeron chair and a nice hardwood desk that I do miss sometimes, hunched over a laptop.

I prefer to work remotely, but as a company, we tend to have strategy meetings in Belfast and company off-sites, which I will come back for. We spend some time talking about strategy and planning. The main benefit is really just to get the team together and spend some time in real life. We will have an office very soon in Belfast, which I’ll try to go to when I’m home.
