Every developer has probably done this at some point.
You create a new project, initialize Git, and then realize you still need to create a .gitignore file.
If you're working with a familiar stack, you probably know which files and directories to exclude. But when you're starting a new project, switching technologies, or working with an unfamiliar tool, things get a little less obvious.
Should node_modules be ignored? What about build output, environment files, IDE settings, caches, or framework-specific directories?
You can write the file yourself, copy one from another project, or search GitHub for an existing template.
I wanted to make that process a little easier, so I built DotGitIgnore.com.
What does it do?
DotGitIgnore is a free .gitignore generator for developers.
The idea is simple: choose the technologies, languages, frameworks, or tools you're using, and generate a .gitignore file that you can use in your project.
Instead of starting from an empty file or digging through repositories to find the right template, you can put together the rules you need in one place.
You can explore the available templates and build a file suited to your project without having to remember every generated directory or temporary file for every technology you use.
It's a small tool, but it's meant to solve a real problem that comes up during everyday development.
The tricky part wasn't the interface
The basic interface for a tool like this is relatively straightforward.
The more interesting challenge is the template collection behind it.
Different languages and frameworks have different conventions. Even within the same ecosystem, the files you want Git to ignore can vary depending on your workflow.
A template that works well for one project might not be enough for another. And blindly combining every possible ignore rule would make the output unnecessarily large and difficult to understand.
That meant thinking about how templates should be organized, how users should discover them, and how the generated output should remain useful rather than simply including as many rules as possible.
I also wanted to build around existing community-maintained templates instead of pretending I needed to invent every rule from scratch.
The goal is to make those resources easier to discover and use.
Building it as a proper web project
I didn't want the project to be only a working generator with a single page.
I also wanted to think about the less visible parts of running a useful developer tool: page structure, performance, discoverability, maintainability, and making sure the site remains straightforward to use.
That led me to work on things like:
- A growing template collection: Making it easier to find ignore rules for different technologies and development environments.
- A focused generator experience: Helping users get from selecting templates to the generated file without unnecessary steps.
- Search-friendly template pages: Giving individual templates a clear purpose and making them easier to discover.
-
A lightweight experience: Keeping the tool centered on its primary job instead of burying it under features that don't help developers generate a
.gitignore.
I'm also exploring ways to make the collection useful for newer AI-assisted development workflows, where projects may include tools and files that traditional templates don't always cover.
There's more to SEO than creating a page for every keyword
One unexpected part of building a public developer tool is thinking about how people will find it.
A developer might search for a general .gitignore generator. Someone else might be looking specifically for a template for Python, Next.js, Java, or a particular IDE.
Supporting those different needs makes sense, but simply creating hundreds of similar pages isn't a great strategy on its own.
Each page should help someone accomplish something.
That means thinking about useful content, internal navigation, canonical URLs, and how the generator itself connects to the template pages. It also means resisting the temptation to create pages just to make the site look bigger.
I'm still working through these challenges, and it's been a useful lesson in the difference between building something that works and building something people can actually discover and use.
Why build something this small?
I like projects that solve a problem developers already understand.
A .gitignore generator isn't a groundbreaking idea, and that isn't the point. Existing tools are useful, but there's still room to build a good experience, learn from the process, and make something that fits naturally into a developer's workflow.
For me, DotGitIgnore is also an opportunity to learn more about building and maintaining a real web product beyond the initial coding phase.
That includes handling a growing template collection, testing changes, thinking about search visibility, and figuring out which features genuinely make the product better.
The work doesn't end when the generator produces the expected output. That's when the next set of questions starts.
Give it a try
If you're starting a new project or just want a quicker way to create your ignore rules, take a look:
I'd also love to hear how other developers manage their .gitignore files.
Do you usually copy a template from an existing project, use GitHub's templates, maintain your own reusable file, or generate one whenever you start something new?
I'm curious what works best for everyone.
Thanks for reading!
