JetBrains All Products Activated — Scripts, Configs, Firewall Tricks

JetBrains Crack Guide — From Lazy Scripts to Full Control

One-Line Flow: Turn any JetBrains IDE into a permanently activated tool using ja-netfilter, firewall blocking, or one-command scripts — no account, no payment, no expiration.

Why Your Wallet Will Thank You

JetBrains IDEs cost $149-649/year. You’re a developer, student, or someone who just wants PyCharm to stop screaming about licenses every 30 days.

This guide hands you every working method as of January 2026 — from one-liner scripts that do everything automatically, to manual configs for the paranoid, to completely legal free licenses most people don’t know exist.

Zero skills required. Copy. Paste. Code.

Pick Your Method (Ranked by Ease)

Rank	Method	Difficulty	Time	Best For
	Free Non-Commercial License	Baby Mode	2 min	WebStorm, Rider, CLion, RubyMine, DataGrip, RustRover users
	ckey.run Script	One Command	1 min	“Just make it work” people
	Firewall Blocking	Copy-Paste	5 min	Performance nerds, clean system lovers
4th	ja-netfilter Manual	Medium	15 min	Control freaks, offline warriors
5th	IDE Eval Reset	Easy	3 min	Temporary use, commitment issues

Still using IntelliJ IDEA, PyCharm, PhpStorm, or GoLand? — Skip to or below. No free legal option yet.

🆓 The Legal Route — Free Non-Commercial Licenses

The “I’m Not Even Breaking Rules” Method

Plot twist: JetBrains made a bunch of IDEs completely free in 2024-2025. Most people have no idea.

Currently Free for Non-Commercial Use

IDE	Free Since	Minimum Version	Get It
RustRover	2024	All versions	Download
Aqua	2024	All versions	Download
WebStorm	Oct 2024	2024.2+	Download
Rider	Oct 2024	2024.2+	Download
CLion	May 2025	2025.1.1+	Download
RubyMine	Sep 2025	2025.2.1+	Download
DataGrip	Oct 2025	2025.2.4+	Download

NOT Free Yet (Need Other Methods)

IntelliJ IDEA Ultimate
PyCharm Professional
PhpStorm
GoLand

What Counts as “Non-Commercial”

You’re good:

Learning / self-education
Hobby projects (side projects you don’t sell)
Open-source contributions (unpaid)
Content creation (YouTube tutorials, Twitch streams, blog posts)

You need to pay:

Freelance work (even $5 gigs)
Work for any employer
Projects you plan to sell or monetize

How to Activate (Step-by-Step)

Step 1: Download and install the IDE (use links above)
        ↓
Step 2: Launch it — a license dialog appears
        ↓
Step 3: Click "Non-commercial use" option
        ↓
Step 4: Log in with JetBrains Account (or create one free)
        → Go to: https://account.jetbrains.com/login
        ↓
Step 5: Accept the agreement
        ↓
Step 6: Done. Full features. One year. Auto-renews.

The Fine Print

Catch	What It Means
Telemetry required	They collect anonymous usage stats. Can’t opt out.
Online activation	Needs internet to activate (works offline after)
Use it or lose it	Must open IDE once every 6 months or renewal fails

Other Free Legal Options

Program	Who Qualifies	Link
Student/Teacher	Valid .edu email or ISIC card	Apply Here
Open Source	Maintain an active OSS project	Apply Here
Startups	<3 years old, <$1M funding	Apply Here

⚡ The One-Command Nuclear Option (ckey.run)

The “I Don’t Want to Think” Method

One command. All products. 2099 expiration. Done.

Windows

Open PowerShell as Administrator, then paste:

irm ckey.run | iex

What this does:

Downloads activation script from ckey.run
Finds all your JetBrains IDEs automatically
Installs ja-netfilter silently
Generates machine-specific activation codes
Activates everything

Mac / Linux

Open Terminal, then paste:

curl -sSL ckey.run | bash

Same process, different syntax.

What You’ll See

JJJJJJ   EEEEEEE  TTTTTTTT  BBBBBBB   RRRRRR    AAAAAA   
   JJ    EE          TT     BB    BB  RR   RR  AA    AA  
   JJ    EEEEE       TT     BBBBBBB   RRRRRR   AAAAAAAA

 JJJJ    EEEEEEE     TT     BBBBBBB   RR   RR  AA    AA  

欢迎使用 JetBrains 激活工具 | CodeKey Run
[WARNING] Script date: 2025-10-31
[WARNING] Please ensure all JetBrains software is closed...

Custom license name (press Enter for default: ckey.run): 
Custom license expiration (press Enter for default: 2099-12-31):

Just hit Enter twice. Let it cook.

Your Antivirus Will Scream

This is normal. The script modifies JVM options, which triggers heuristic scanners.

Fix:

Add exclusion folder: C:\ja-netfilter\ (Windows) or ~/ja-netfilter/ (Mac/Linux)
Or temporarily disable real-time protection
Or run in a VM if you’re paranoid

The script is open-source. You can read it at ckey.run before running.

Supported Products

All of them. Literally every JetBrains IDE:

IDE	Status	IDE	Status
IntelliJ IDEA		WebStorm
PyCharm		Rider
PhpStorm		CLion
GoLand		RubyMine
DataGrip		RustRover
DataSpell		AppCode

🔥 The No-Agent Method (iptables/Firewall Blocking)

The “Cleanest System” Method

No javaagent. No startup slowdown. Just block JetBrains from phoning home.

Why This Works (Simple Version)

Normal flow:
You activate → IDE checks with JetBrains → "This key is blacklisted" → Sad

Blocked flow:
You activate → IDE tries to check → Can't reach server → "Guess it's valid ¯\_(ツ)_/¯" → Happy

Why /etc/hosts Doesn’t Work Anymore

JetBrains got smart. Their IDE bypasses your hosts file by querying DNS servers directly:

8.8.8.8 (Google)
1.1.1.1 (Cloudflare)
9.9.9.9 (Quad9)

You need firewall-level blocking.

Linux (iptables)

Copy-paste this entire block:

# Block DNS queries for JetBrains domains
sudo iptables -I OUTPUT -p udp --dport 53 -m string --hex-string "|03|www|09|jetbrains|03|com|" --algo bm -j DROP
sudo iptables -I OUTPUT -p udp --dport 53 -m string --hex-string "|07|account|09|jetbrains|03|com|" --algo bm -j DROP
sudo ip6tables -I OUTPUT -p udp --dport 53 -m string --hex-string "|03|www|09|jetbrains|03|com|" --algo bm -j DROP
sudo ip6tables -I OUTPUT -p udp --dport 53 -m string --hex-string "|07|account|09|jetbrains|03|com|" --algo bm -j DROP

# Make it survive reboots
sudo apt install iptables-persistent -y
sudo iptables-save | sudo tee /etc/iptables/rules.v4 > /dev/null
sudo ip6tables-save | sudo tee /etc/iptables/rules.v6 > /dev/null

echo "Done. JetBrains can't phone home anymore."

Windows (PowerShell as Admin)

Copy-paste this entire block:

$domains = @(
    "www.jetbrains.com",
    "account.jetbrains.com",
    "jetbrains.com",
    "www-weighted.jetbrains.com"
)

foreach ($d in $domains) {
    New-NetFirewallRule -DisplayName "BLOCK_JB_OUT_$d" -Direction Outbound -RemoteFQDN $d -Action Block -Profile Any -ErrorAction SilentlyContinue
    New-NetFirewallRule -DisplayName "BLOCK_JB_IN_$d" -Direction Inbound -RemoteFQDN $d -Action Block -Profile Any -ErrorAction SilentlyContinue
}

Write-Host "✅ JetBrains domains blocked. Rules persist after reboot." -ForegroundColor Green

Check if it worked:

Get-NetFirewallRule | Where-Object DisplayName -like "BLOCK_JB_*"

Remove rules later:

Get-NetFirewallRule | Where DisplayName -like "BLOCK_JB_*" | Remove-NetFirewallRule

Now Get Your Activation Code

Go to 3.jetbra.in
Click any online IPFS gateway (green = online)
Find your product
Copy the activation code
In IDE: Help → Register → Activation Code → Paste → Activate

No ja-netfilter needed. The firewall does all the work.

What You Lose

Feature	Why It’s Dead
AI Assistant	Cloud-based, needs account.jetbrains.com
Junie AI	Same deal
Settings Sync	Needs JetBrains account
Plugin Marketplace	Can’t reach plugins.jetbrains.com

Workaround for plugins: Download .zip from plugins.jetbrains.com on another device, install manually via Settings → Plugins → ⚙️ → Install from Disk

🛠️ ja-netfilter — The OG Method (Manual Setup)

The “I Want Full Control” Method

The original. The classic. Created by pengzhile (zhile.io).

How It Actually Works

JetBrains License Check:
1. IDE receives activation code
2. Code contains JSON data + RSA signature
3. IDE uses BigInteger.modPow() to verify signature
4. If signature valid → activated

ja-netfilter Intercept:
1. You load ja-netfilter as a javaagent
2. When IDE calls BigInteger.modPow()...
3. ja-netfilter intercepts it
4. Returns "yep, signature checks out" (it doesn't)
5. IDE believes it → activated

Translation: ja-netfilter lies to the IDE about math. The IDE trusts math. The IDE is wrong.

Step 1: Download ja-netfilter

Go to: 3.jetbra.in

Click any green (online) IPFS gateway
Download jetbra.zip (latest version: 251031)
Extract to a permanent location:

OS	Recommended Path
Windows	`C:\ja-netfilter\`
Linux	`/opt/ja-netfilter/`
Mac	`~/ja-netfilter/`

Don’t put it in Downloads. Don’t put it somewhere with spaces in the path.

Step 2: Configure power.conf

Open config/power.conf in the extracted folder.

Delete everything and paste this exact content:

[Args]

[Result]
EQUAL,55225648167853313963797564236788620375823669548347220922774310709827403911518263287616387100268543266230233866848442341418362382822530312949501167824269284249248881651498967624678824814834241326748519556823164148221689826687743835412828706076663185916147933220572566657446416402052253759570336207556523489026379081126562829355365677692595954505412289246859665634951468451820899724375004402183725193875327880750230568511397071721883183561863845775813024476963452564494937450851704460199094811762010527172042825951890903134141793321152616818473718423963489394847508510942048152224335892799808050861335612369288976777

That giant number is the fake RSA result. Don’t modify it. Don’t add spaces. Don’t break the line.

Step 3: Configure url.conf

Open config/url.conf.

Add these lines:

[URL]
PREFIX,https://account.jetbrains.com/lservice/rpc/validateKey.action
PREFIX,https://account.jetbrains.com.cn/lservice/rpc/validateKey.action

This blocks the IDE from checking if your key is blacklisted.

Step 4: Find Your IDE’s vmoptions File

Option A: Let the IDE show you

Open your IDE
Help → Edit Custom VM Options
A file opens. That’s it.

Option B: Manual locations

OS	Path
Windows	`%APPDATA%\JetBrains\<Product><Version>\<product>.vmoptions`
Linux	`~/.config/JetBrains/<Product><Version>/<product>.vmoptions`
Mac	`~/Library/Application Support/JetBrains/<Product><Version>/<product>.vmoptions`

Examples:

Windows PyCharm: C:\Users\YOU\AppData\Roaming\JetBrains\PyCharm2025.1\pycharm64.exe.vmoptions
Mac IntelliJ: ~/Library/Application Support/JetBrains/IntelliJIdea2025.1/idea.vmoptions
Linux WebStorm: ~/.config/JetBrains/WebStorm2025.1/webstorm64.vmoptions

Step 5: Add javaagent Lines

Add these 3 lines at the end of your vmoptions file:

--add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
--add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
-javaagent:/path/to/ja-netfilter.jar=jetbrains

Replace /path/to/ with your actual path:

OS	Example
Windows	`-javaagent:C:\ja-netfilter\ja-netfilter.jar=jetbrains`
Linux	`-javaagent:/opt/ja-netfilter/ja-netfilter.jar=jetbrains`
Mac	`-javaagent:/Users/yourname/ja-netfilter/ja-netfilter.jar=jetbrains`

Path has spaces? Use quotes or forward slashes:

-javaagent:"C:\Program Files\ja-netfilter\ja-netfilter.jar"=jetbrains

Step 6: Restart IDE & Get Activation Code

Close the IDE completely
Go to 3.jetbra.in
Find your product, copy the activation code
Reopen IDE
Help → Register → Activation Code → Paste → Activate

The displayed expiration date is fake. It might say 2025 or 2026. Ignore it. The license is perpetual.

Step 7: Verify It Worked

Help → About should show:

Licensed to: [some name]
License type: Commercial/Personal

If it still says “Evaluation” or shows a trial countdown, something went wrong. Check Troubleshooting.

🔌 Paid Plugin Activation (Tampermonkey Method)

Premium Plugins for Free

Material Theme UI, RainbowBrackets Pro, Laravel Idea, etc. — they cost money. Here’s how to activate them.

Prerequisites

ja-netfilter must be configured with correct power.conf (see above)
Tampermonkey browser extension installed

Method 1: MyJBLS Script (Recommended)

Step	Action
1	Install Tampermonkey for your browser
2	Go to MyJBLS on Greasyfork
3	Click “Install this script”
4	Visit plugins.jetbrains.com
5	Browse to any paid plugin
6	A new “ Get Activation Code” button appears
7	Click it, copy the code
8	In IDE: `Help → Register → Manage Licenses → Plugins tab → Add`
9	Paste code, activate

Backend server: https://jbls.ide-soft.com

Method 2: JetBra Script (Alternative)

Same process, different script:

JetBra on Greasyfork

This one embeds a private key and generates codes locally (no server call).

Method 3: Web Generator

No Tampermonkey needed:

Go to: jetbrains.ankio.net/license

Select your plugin from the list (290+ supported)
Click “Generate”
Copy code
Paste in IDE

🧰 Toolbox App Complications

Using JetBrains Toolbox? Read This.

Toolbox manages vmoptions differently. Don’t edit files directly — Toolbox will overwrite them.

vmoptions Locations (For Reference Only)

OS	Path
Windows	`%LOCALAPPDATA%\JetBrains\Toolbox\apps\<PRODUCT>\ch-0\<version>\bin\`
Mac	`~/Library/Application Support/JetBrains/Toolbox/apps/<PRODUCT>/ch-0/<version>/`
Linux	`~/.local/share/JetBrains/Toolbox/apps/<product>/ch-0/<version>/bin/`

The Right Way to Configure

Step 1: Open Toolbox App
        ↓
Step 2: Find your IDE in the list
        ↓
Step 3: Click the ⚙️ gear icon next to it
        ↓
Step 4: Click "Settings"
        ↓
Step 5: Scroll to "Configuration"
        ↓
Step 6: Find "Java Virtual Machine options"
        ↓
Step 7: Click "Edit..."
        ↓
Step 8: Add your 3 lines here:
        --add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
        --add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
        -javaagent:/path/to/ja-netfilter.jar=jetbrains
        ↓
Step 9: Save and restart IDE

Toolbox will preserve your changes across updates.

🍎 macOS Specifics

Apple Silicon (M1/M2/M3/M4)

All JetBrains IDEs run natively on ARM since late 2021. ja-netfilter is pure Java — works perfectly.

No Rosetta needed. No special configuration.

Code Signing Issues

If IDE crashes with “Code Signature Invalid”:

Problem	Solution
Modified .app bundle	Re-download IDE fresh
ja-netfilter inside /Applications	Move it to `~/ja-netfilter/`
Corrupted download	Use Toolbox App to install instead

Correct Path Format

-javaagent:/Users/yourname/ja-netfilter/ja-netfilter.jar=jetbrains

Not:

-javaagent:~/ja-netfilter/ja-netfilter.jar=jetbrains  ← Won't work
-javaagent:/Applications/ja-netfilter/ja-netfilter.jar=jetbrains  ← Might break signing

🐧 Linux Automation (dhay3 Installer)

One-Click Installer for Linux

If you don’t want to configure manually:

GitHub: github.com/dhay3/ja-netfilter

Features

Feature	Description
Auto-config	Uses `environment.d` to set VM options system-wide
DE-agnostic	Works with GNOME, KDE, Xfce, i3, whatever
Bundled codes	Activation codes included in `licenses/` folder
Interactive	Choose which IDEs to activate

Installation

# Download latest release
wget https://github.com/dhay3/ja-netfilter/releases/latest/download/ja-netfilter.tar.bz2

# Extract
bzip2 -d ja-netfilter.tar.bz2 && tar xvf ja-netfilter.tar

# Run installer
cd ja-netfilter
./install.sh

# Follow the prompts

How It Works

Instead of editing each IDE’s vmoptions, it sets environment variables:

IDEA_VM_OPTIONS=/path/to/custom.vmoptions
PYCHARM_VM_OPTIONS=/path/to/custom.vmoptions
# etc.

These are exported via ~/.config/environment.d/ so they apply to all sessions, regardless of how you launch the IDE.

🐳 Docker / Container Usage

The Problem

JetBrains stores license info in:

Config directory (~/.config/JetBrains/)
System keychain (Mac) or registry (Windows)

Containers are ephemeral. License disappears on restart.

The Solution

Use activation codes + firewall blocking. Don’t rely on account-based activation.

Mount the config directory:

docker run -v ~/.config/JetBrains:/root/.config/JetBrains \
           -v ~/ja-netfilter:/opt/ja-netfilter \
           your-jetbrains-image

Or bake the activation into your Dockerfile:

COPY ja-netfilter /opt/ja-netfilter
COPY idea.vmoptions /root/.config/JetBrains/IntelliJIdea2025.1/
# Pre-configure activation code in config

🔄 IDE Eval Reset (Trial Extension)

The “I Just Need 30 More Days Forever” Method

Doesn’t crack anything. Just resets the trial period. Indefinitely.

Installation

Step	Action
1	Open IDE
2	`Settings → Plugins → ⚙️ → Manage Plugin Repositories`
3	Add: `https://plugins.zhile.io`
4	Go to `Marketplace` tab
5	Search “IDE Eval Reset”
6	Install it
7	Restart IDE

Usage

Manual reset:
Help → Eval Reset → Reset (IDE restarts)

Automatic reset:
Check “Auto reset before per restart” in the Eval Reset window. Now it resets every time you close the IDE.

Limitations

Issue	Reality
Must restart regularly	At least once every ~25 days
Some IDEs hang	CLion especially has exit issues
It’s not real activation	Just trial extension forever
Same author	zhile.io made both this and ja-netfilter

When to Use This

You only need the IDE temporarily
You’re testing before committing to ja-netfilter
You have commitment issues with software

🪦 Deprecated: BetterIntelliJ

Don’t Use This. Seriously.

From 2018-2021, BetterIntelliJ was the go-to. It’s dead now.

Why It’s Dead

Problem	Explanation
Security issues	Chinese forums report it was “篡改过” (tampered with)
Codes blacklisted	JetBrains banned all known BetterIntelliJ keys
Bypassed by JB	It used hosts file blocking — JetBrains now ignores hosts
Replaced	ja-netfilter does everything better

If You Have It Installed

Remove it:

Settings → Plugins → Installed
Find “BetterIntelliJ”
Uninstall
Also check your vmoptions file — it auto-adds itself

⚠️ Troubleshooting

“This license has been cancelled”

Translation: JetBrains blacklisted your activation code.

Solution	How
1. Block validation	Use firewall method (most reliable)
2. Update hosts	Add `0.0.0.0 account.jetbrains.com` (might not work alone)
3. Fresh code	Get new one from 3.jetbra.in

“Key is invalid”

Translation: power.conf is wrong or ja-netfilter isn’t loading.

Checklist:

power.conf has the 617-digit EQUAL line?
No extra spaces or line breaks in power.conf?
vmoptions path to ja-netfilter is correct?
vmoptions has the two --add-opens lines?

IDE Won’t Start After Adding javaagent

Cause	Fix
Path has spaces	Use quotes: `-javaagent:"C:\my path\ja-netfilter.jar"=jetbrains`
Path has non-ASCII	Move ja-netfilter to ASCII-only location like `C:\janf\`
Missing --add-opens	Required for JetBrains 2022.2+ (they use Java 17+)
Wrong path syntax	Windows: use `\` or `/`. Don’t mix.

Activation Works but Expires Later

Translation: JetBrains is phoning home and invalidating your license.

The IDE checks validity even in “offline mode.” Use:

Firewall blocking (recommended), or
url.conf in ja-netfilter config

Windows Defender Deletes ja-netfilter

This is a false positive. ja-netfilter modifies JVM behavior, which looks suspicious.

Fix:

Windows Security → Virus & threat protection
Manage settings → Exclusions
Add an exclusion → Folder
Select your ja-netfilter folder

Or just rename ja-netfilter.jar to something boring like java-agent.jar.

Debug Mode (See What’s Happening)

Linux/Mac:

export JANF_DEBUG=1
# Then launch IDE from terminal

All platforms (add to vmoptions):

-Djanf.debug=1

Now ja-netfilter will log what it’s doing.

📊 Version Compatibility Matrix

Does It Work on My Version?

IDE Version	ja-netfilter	ckey.run	Firewall	Notes
2024.1.x				Standard config
2024.2.x				Add .cn domain to url.conf
2024.3.x				Unified distribution
2025.1.x				Needs updated power.conf
2025.2.x				Working
2025.3.x				Current latest

Success Rates (from Chinese forum reports)

Version	Rate	Notes
2024.1	95%+	Smooth sailing
2024.2	90%+	After url.conf fix for China region
2024.3	85%	Unified distribution caused initial issues
2025.1+	95%+	After power.conf number update

🔐 What Can't Be Cracked

Server-Side = Game Over

Some features run entirely on JetBrains’ servers. No local bypass exists.

Feature	Why It’s Uncrackable
JetBrains AI Assistant	Processing happens on their cloud
Junie AI	Same deal — online only
Settings Sync	Requires authenticated JetBrains account
Code With Me (Full)	Server validates session participants

If you block JetBrains domains: These features die completely.

If you want them: Buy a license. There’s literally no workaround.

Final Notes

This works because JetBrains uses client-side validation. The IDE checks a signature locally, ja-netfilter lies about the math, and everyone’s happy. They could move to server-side validation like Adobe did, but that would break offline development — their enterprise customers would riot.

The legal reality: This violates JetBrains’ Terms of Service. Whether it violates law depends on your jurisdiction. Educational use, personal exploration, and reverse engineering for interoperability have various protections in various places. Commercial use is clearly over the line everywhere.

The practical reality: JetBrains knows about all of this. They’ve known for years. They haven’t gone nuclear because their business model is enterprise licensing, not hunting individual developers. The crackdown would cost more than they’d recover.

Use responsibly. If you make money with these tools, buying a license is the right thing to do.
