.gitignore Template Maker
Select languages and environments to build a combined .gitignore file.
Select one or more templates above to generate your .gitignore
.gitignore generator for Node.js, Python, React, Go, and 30+ stacks
Every project needs a well-crafted .gitignore to keep secrets, build artefacts, and editor junk out of version control. Manually assembling these rules from memory is tedious and error-prone. AlteredIdea's generator lets you combine templates for any number of languages and tools, merging them into a single deduplicated file you can commit immediately.
From a solo Node.js microservice to a polyglot monorepo spanning Python, Go, and TypeScript, the right .gitignore protects your repository from accidental commits of .env secrets, gigabyte node_modules folders, and IDE configuration files that differ between team members' machines.
How to use: step by step
- 1Search for your stack
Type a language, framework, or tool name (e.g. 'python', 'react', 'jetbrains') in the search box to filter available templates. - 2Select one or more templates
Click each template you need. You can combine multiple stacks: for example Node + React + macOS + JetBrains. - 3Preview the merged output
The generated .gitignore appears in real time, automatically deduplicating overlapping rules across all selected templates. - 4Copy or download
Click Copy to copy to clipboard, or download the file directly. Save it as .gitignore in the root of your repository. - 5Commit to your repo
Run git add .gitignore && git commit -m 'chore: add .gitignore' to start ignoring unwanted files immediately.

Frequently Asked Questions
- What is a .gitignore file?
- A .gitignore file tells Git which files and directories to exclude from version control. Common examples include node_modules, build output directories, .env files containing secrets, and operating-system artifacts like .DS_Store.
- How do I combine multiple templates?
- Simply select all the templates you need: the generator merges them into a single file, removing duplicate entries. This is useful for monorepos or full-stack projects that span multiple languages.
- Will the generated .gitignore affect files already tracked by Git?
- No. .gitignore only prevents untracked files from being added. If a file is already committed, you must run git rm --cached <file> to stop tracking it.
- What is the difference between a global and a project .gitignore?
- A project .gitignore (placed in the repo root) is shared with all contributors. A global gitignore (~/.config/git/ignore) applies to all your repos on your machine and is ideal for editor files and OS artifacts.
- Why does my node_modules folder still appear in git status?
- If node_modules was committed before the .gitignore was added, it is still tracked. Run git rm -r --cached node_modules to untrack it, then commit.
- Can I add custom rules on top of the generated output?
- Yes. The generated file is plain text: paste it into your editor and add any project-specific patterns at the bottom. For example, *.local or /secrets/ for local config files.
- Should .gitignore itself be committed?
- Yes. The .gitignore file should always be committed so that all team members and CI/CD systems share the same ignore rules.
- How do negation patterns work in .gitignore?
- A pattern starting with ! re-includes a file that was previously ignored. For example, if you ignore *.log but want to keep error.log, add !error.log after the *.log line.
- Does .gitignore work for nested directories?
- A pattern without a slash matches anywhere in the tree. A pattern with a leading slash (e.g. /build) only matches the repo root. Place .gitignore files in subdirectories to scope rules to that subtree.
- Are generated gitignore patterns based on official GitHub templates?
- The templates are derived from widely adopted community patterns, similar in content to the official github/gitignore repository, covering all major languages and editors.
