Should You Commit the .idea Directory?

Partially. The .idea directory that JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, PhpStorm) drop into your project root holds two different kinds of files mixed together: shared project policy that every contributor benefits from, and per-user machine state that creates churn and conflicts. The wrong move is treating the whole folder as one decision — either committing all of it (noise, merge hell) or gitignoring all of it (you throw away shared run configs and code style that the team actually wants versioned).

This is the same shape as the .vscode directory question: the answer is "it depends, per file." The difference is that .idea is noisier by default — JetBrains writes far more state into it, and a lot of that state changes every time you open a file or move a window. So the practical default leans toward ignoring most of it and committing a deliberate, small set.

The short answer

Question	Answer
Commit the whole `.idea` folder?	No — it mixes shared policy with per-user state.
Gitignore the whole `.idea` folder?	No — you lose shared run configs and code style.
Best approach?	Commit a deliberate whitelist; ignore the rest.
Solo project, just you?	Committing all of it is fine but pointless — ignore it.
Using JetBrains' own `.idea/.gitignore`?	Yes — it already excludes the worst per-user files.

The principle: commit project policy, ignore machine state. A file that encodes a decision the team agreed on (how code is formatted, which inspections run, how to launch the app) belongs in history. A file that records how your window was laid out this morning does not.

What's actually in .idea

The .idea directory is JetBrains' per-project settings store, the equivalent of .vscode for VS Code. JetBrains itself splits the contents into two buckets:

Shareable — settings that describe the project, not the person. Code style, inspection profiles, VCS mappings, and run configurations you want teammates to inherit.
Per-user — settings that describe your local session. Which files you have open, your window layout, shelved changes, task history, and usage telemetry.

The folder is created automatically the moment you open a project in any JetBrains IDE, so it appears whether or not you asked for it — which is exactly why so many of these files sail into a first git add . before anyone has thought about the distinction.

The file-by-file rule

This is the whole decision. As of 2026, JetBrains' guidance and the standard .idea/.gitignore template land here:

File / folder	Commit?	What it holds
`.idea/workspace.xml`	Ignore	Open files, window layout, recent locations — pure per-user state.
`.idea/tasks.xml`	Ignore	Local task/context history. Churns constantly.
`.idea/usage.statistics.xml`	Ignore	Per-user telemetry.
`.idea/shelf/`	Ignore	Your shelved (uncommitted) changes. Local by definition.
`.idea/dictionaries/`	Usually ignore	Personal spelling dictionary. Commit only if the team shares one.
`*.iml` (module files)	Usually ignore	Module definitions, regenerated by Gradle/Maven import.
`.idea/modules.xml`	Usually ignore	Module index, regenerated alongside `.iml` files.
`.idea/vcs.xml`	Commit	VCS root mappings. Shared and stable.
`.idea/codeStyles/`	Commit	Formatting rules — team policy.
`.idea/inspectionProfiles/`	Commit	Which inspections run and at what severity.
`.idea/runConfigurations/`	Commit if shared	How to launch/test the app, when the team wants it versioned.

The *.iml and modules.xml rows are the ones that surprise people. In a modern Gradle- or Maven-based project, the IDE regenerates these from the build file on import, so committing them just means stale, machine-specific module paths that conflict between contributors. In an older project that doesn't use a build tool for import, the .iml files are the only record of module structure and you do need them. Check whether your project re-imports cleanly without them before deciding.

How to set it up

The cleanest setup is to ignore the whole folder, then force-add the specific files you want shared. That way new per-user files JetBrains invents in future versions are ignored by default instead of leaking in.

# Ignore everything in .idea by default
.idea/*

# ...then un-ignore the shared, project-level settings
!.idea/vcs.xml
!.idea/codeStyles/
!.idea/inspectionProfiles/
!.idea/runConfigurations/

The .idea/* line (with the trailing /*, not just .idea/) is what makes the ! un-ignore lines work — Git can't re-include a file inside a directory it has excluded wholesale, but it can if you excluded the directory's contents. This is the same negation pattern that trips people up with .vscode.

JetBrains also maintains its own .idea/.gitignore inside the folder, which it writes automatically and which already excludes workspace.xml, shelf/, usage.statistics.xml, and friends. You can lean on that file instead of listing those exclusions yourself — commit the .idea/.gitignore JetBrains generates and let it carry the per-user exclusions, while your root .gitignore handles the whitelist.

Removing .idea files already committed

If the whole folder is already tracked and you want to walk it back, adding ignore rules isn't enough — .gitignore only affects untracked files. Stop tracking the per-user files explicitly:

# Stop tracking the noisy per-user files, keep them on disk
git rm --cached .idea/workspace.xml .idea/tasks.xml .idea/usage.statistics.xml
git rm -r --cached .idea/shelf .idea/dictionaries

# Stop tracking generated module files (if your build tool regenerates them)
git rm --cached .idea/modules.xml
find . -name "*.iml" -print0 | xargs -0 git rm --cached --ignore-unmatch

# Then commit with the new ignore rules in place
git commit -m "Stop tracking per-user .idea files, keep shared settings"

--cached removes the files from Git's index but leaves them on disk, so your IDE keeps working untouched. After this commit, your .idea/* + whitelist rules take over and only the shared files stay tracked.

.idea vs .vscode vs other editor config

.idea follows the same machine-state-vs-project-policy rule as every other editor and tool config file. The only thing that changes is how aggressively each tool mixes the two:

File / folder	Created by	Default call	Why
`.idea/`	JetBrains IDEs	Partial	Whitelist shared settings, ignore per-user state.
`.vscode/`	VS Code	Partial	Commit `extensions.json`/shared tasks, ignore personal prefs.
`.editorconfig`	Cross-editor	Commit	Pure shared formatting policy, no per-user state.
`.prettierrc`	Prettier	Commit	Shared formatting rules.
Cursor config	Cursor	Partial	Shared AI rules yes, personal settings no.

The cleaner the separation between policy and state, the easier the call. .editorconfig is all policy, so it's an unconditional commit. .idea is the messiest of the group because JetBrains stuffs window layout and telemetry into the same folder as your code style — hence the whitelist approach rather than a simple yes or no.

The bottom line

Don't treat .idea as one decision. Ignore the folder by default, then commit the four things your team actually shares: vcs.xml, codeStyles/, inspectionProfiles/, and shared runConfigurations/. Leave workspace.xml, tasks.xml, shelf/, telemetry, and (in build-tool projects) the .iml/modules.xml files ignored, because they're per-user state that only generates churn and conflicts.

If the folder is already fully tracked, git rm --cached the per-user files and let JetBrains' own .idea/.gitignore plus your whitelist take over. The result: teammates inherit your formatting and run configs, nobody fights over whose window was open where.
