# 🔓 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.**

> 
> ```powershell
> irm ckey.run | iex
> 
> ```
> 
> **What this does:**
> 
> 1. Downloads activation script from ckey.run

> 4. Generates machine-specific activation codes
> 5. Activates everything
> 
> * * *
> 
> ### 🍎 Mac / 🐧 Linux
> 
> **Open Terminal** , then paste:
> 
> ```bash
> curl -sSL ckey.run | bash
> 
> ```
> 
> Same process, different syntax.

> * * *
> 
> ### ⚠ Your Antivirus Will Scream
> 
> **This is normal.** The script modifies JVM options, which triggers heuristic scanners.
> 
> **Fix:**
> 
> 1. Add exclusion folder: `C:\ja-netfilter\` (Windows) or `~/ja-netfilter/` (Mac/Linux)
> 2. Or temporarily disable real-time protection
> 3. Or run in a VM if you’re paranoid
> 
> **The script is open-source.** You can read it at [ckey.run](https://ckey.run) before running.
> 
> * * *
> 
> ### Supported Products
> 
> All of them. Literally every JetBrains IDE:
> 
> | IDE | Status | IDE | Status |

> **🔥 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)
> 
> ```auto
> 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:
> 
> ```bash
> # 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:
> 
> ```powershell
> $domains = @(
> "www.jetbrains.com",
> "account.jetbrains.com",
> "jetbrains.com",
> "www-weighted.jetbrains.com"
> )
> 
> foreach ($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:**
> 
> ```powershell
> Get-NetFirewallRule | Where-Object DisplayName -like "BLOCK_JB_*"
> 
> ```
> 
> **Remove rules later:**
> 
> ```powershell
> Get-NetFirewallRule | Where DisplayName -like "BLOCK_JB_*" | Remove-NetFirewallRule
> 
> ```
> 
> * * *
> 
> ### Now Get Your Activation Code
> 
> 1. Go to [3.jetbra.in](https://3.jetbra.in)
> 2. Click any online IPFS gateway (green = online)
> 3. Find your product
> 4. Copy the activation code
> 5. In IDE: `Help → Register → Activation Code → Paste → Activate`

> **🛠️ ja-netfilter — The OG Method (Manual Setup)**
>
> ## The “I Want Full Control” Method
> 
> The original. The classic. Created by **pengzhile** ([zhile.io](https://zhile.io)).
> 
> * * *
> 
> ### How It Actually Works
> 
> ```auto
> 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](https://3.jetbra.in)**
> 
> ![image](https://onehack.st/uploads/default/original/3X/2/1/21aade52911d4b29c6204410711982d4813a4e78.png)
> 
> 1. Click any green (online) IPFS gateway
> 2. Download `jetbra.zip` (latest version: 251031)
> 3. 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:**
> 
> ```ini
> [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:**
> 
> ```ini
> [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**
> 
> 1. Open your IDE
> 2. `Help → Edit Custom VM Options`
> 3. 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:
> 
> ```auto
> --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
> 
> ```
> 
> ![image](https://onehack.st/uploads/default/original/3X/5/2/5229d54c75d542710c36f40808c5069d7818eebd.jpeg)
> 
> **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:
> 
> ```auto
> -javaagent:"C:\Program Files\ja-netfilter\ja-netfilter.jar"=jetbrains
> 
> ```
> 
> * * *
> 
> ### Step 6: Restart IDE & Get Activation Code
> 
> 1. **Close the IDE completely**
> 2. Go to [3.jetbra.in](https://3.jetbra.in)
> 3. Find your product, copy the activation code
> 4. Reopen IDE
> 5. `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
> 
> ![image](https://onehack.st/uploads/default/original/3X/3/6/36531dd60b25beaff719db812957a797bfb424fb.png)

> 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](https://www.tampermonkey.net/) browser extension installed
> 
> * * *
> 
> ### Method 1: MyJBLS Script (Recommended)
> 
> | Step | Action |
> | --- | --- |
> | 1 | Install [Tampermonkey](https://www.tampermonkey.net/) for your browser |
> | 2 | Go to [MyJBLS on Greasyfork](https://greasyfork.org/en/scripts/489057-myjbls) |

> 
> Same process, different script:
> 
> [JetBra on Greasyfork](https://greasyfork.org/en/scripts/480799-jetbra)
> 
> This one embeds a private key and generates codes locally (no server call).
> 
> * * *
>

> 
> 1. Select your plugin from the list (290+ supported)
> 2. Click “Generate”
> 3. Copy code
> 4. 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
> 
> ```auto
> 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
> 
> ```auto
> -javaagent:/Users/yourname/ja-netfilter/ja-netfilter.jar=jetbrains
> 
> ```
> 
> **Not:**
> 
> ```auto
> -javaagent:~/ja-netfilter/ja-netfilter.jar=jetbrains ← Won't work
> -javaagent:/Applications/ja-netfilter/ja-netfilter.jar=jetbrains ← Might break signing
> 
> ```

> 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

> * * *
> 
> ### How It Works
> 
> Instead of editing each IDE’s vmoptions, it sets environment variables:
> 
> ```bash
> 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:
> 
> ```bash
> docker run -v ~/.config/JetBrains:/root/.config/JetBrains \
> -v ~/ja-netfilter:/opt/ja-netfilter \
> your-jetbrains-image
> 
> ```
> 
> Or bake the activation into your Dockerfile:
> 
> ```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](http://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:**
> 
> 1. `Settings → Plugins → Installed`
> 2. Find “BetterIntelliJ”
> 3. Uninstall
> 4. **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](https://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:**
> 
> 1. `Windows Security → Virus & threat protection`
> 2. `Manage settings → Exclusions`
> 3. `Add an exclusion → Folder`
> 4. 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:**
> 
> ```bash
> export JANF_DEBUG=1
> # Then launch IDE from terminal
> 
> ```
> 
> **All platforms (add to vmoptions):**
> 
> ```auto
> -Djanf.debug=1
> 
> ```
> 
> Now ja-netfilter will log what it’s doing.

## 📝 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.
