IronBullet can import configs from OpenBullet 1 (.svb), OpenBullet 2 (.opk), and standalone LoliCode (.loli) files. The importer automatically converts blocks, settings, and variables to IronBullet’s native format.

Prepare Your Config File

Locate your OpenBullet config file. Common locations:OpenBullet 1 (SilverBullet):
OpenBullet/Configs/YourConfig.svb
OpenBullet 2:
OpenBullet2/Configs/YourConfig.opk
.opk files are ZIP archives containing:
  • script.loli - Main LoliCode script
  • metadata.json - Config name, author, etc.
  • settings.json - Runner/proxy/data settings

Import via GUI

Method 1: File Menu
  1. Click File → Import Config
  2. Select your .svb, .opk, .loli, or .json file
  3. Review the import warnings (if any)
  4. Click Import
Method 2: Drag & Drop
  1. Drag the config file into the IronBullet window
  2. Confirm import in the dialog
The config opens in a new tab. Original file is not modified.
3

Import via CLI

You can run imported configs directly from the command line:
# Import and run an .svb config
ironbullet --config login.svb --wordlist combos.txt --threads 100

# Import an .opk package
ironbullet --config config.opk --wordlist combos.txt --proxies proxies.txt

# LoliCode script
ironbullet --config script.loli --wordlist data.txt
IronBullet auto-detects the format and imports on-the-fly.

Review Import Warnings

After import, check the Warnings panel (bottom of screen).Common warnings:Unsupported Block Type
[warn] Unsupported block type: Translate — converted to disabled script
Some OB2 blocks don’t have IronBullet equivalents. They’re converted to disabled Script blocks with the original code in comments.Variable Reference Conversion
[warn] Variable <USER> converted to <input.USER>
OpenBullet uses <USER> for wordlist variables. IronBullet uses <input.USER> for clarity.Unknown Function
[warn] Unknown SVB function: CountOccurrences
Advanced string functions may need manual implementation.
5

Fix Converted Blocks

Review blocks marked as Script or disabled:
  1. Open the block settings
  2. Read the commented code
  3. Recreate using IronBullet blocks:
    • Translate → Use IfElse or CaseSwitch
    • CountOccurrences → Use ParseRegex with regex groups
    • Substring → Use StringFunction block
Example - Convert Translate block:OpenBullet (LoliCode):
FUNCTION Translate
  KEY "EN" VALUE "English"
  KEY "FR" VALUE "French"
  "<LANG>" -> VAR @LANGUAGE
IronBullet (CaseSwitch block):
Input Variable: LANG
Cases:
  - Match: EN → Output: English
  - Match: FR → Output: French
Default: Unknown
Output Variable: LANGUAGE

Update Variable References

IronBullet uses a different variable namespace:
OpenBulletIronBulletDescription
<USER><input.USER>Wordlist data slice
<PASS><input.PASS>Wordlist data slice
<SOURCE><data.SOURCE>HTTP response body
<RESPONSECODE><data.RESPONSECODE>HTTP status code
<ADDRESS><data.ADDRESS>Final URL after redirects
<COOKIES(name)><data.COOKIES["name"]>Cookie value
The importer handles most conversions automatically.

Test the Imported Config

Before running on a full wordlist:
  1. Press F5 (Debug mode)
  2. Enter test data: test@example.com:password123
  3. Verify all blocks execute correctly
  4. Check the Variables panel for expected outputs
  5. Review Request/Response tabs for HTTP calls
Fix any errors before creating a job.
8

Adjust Settings

Review imported settings (footer panels):Data Settings:
  • Wordlist type (Credentials, Emails, etc.)
  • Separator character
  • Slice names (USER, PASS)
Proxy Settings:
  • OB1 NeedsProxies: true → Proxy Mode: Rotate
  • OB2 UseProxies: true → Proxy Mode: Rotate
  • Ban duration (default: 300s)
Runner Settings:
  • Threads (OB1/OB2 SuggestedBots)
  • Concurrent per proxy
  • Continue statuses

Save as Native Format

Once you’ve verified the import:
  1. Click File → Save As
  2. Choose .rfx format (IronBullet native)
  3. Give it a descriptive name: LoginChecker.rfx
.rfx files load faster and preserve all IronBullet-specific features.

Import Code Reference

The importer logic is in ~/workspace/source/src/import/:

​
SVB (SilverBullet) Import

Example .svb structure: 
[SETTINGS]
{
  "Name": "Example Config",
  "Author": "reqflow",
  "NeedsProxies": true,
  "AllowedWordlist1": "MailPass"
}

[SCRIPT]
#LoginRequest REQUEST POST "https://example.com/login"
  CONTENT "{\"user\":\"<USER>\",\"pass\":\"<PASS>\"}"
  CONTENTTYPE "application/json"
  HEADER "Accept: application/json"

KEYCHECK
  KEYCHAIN Success OR
    KEY "<RESPONSECODE>" EqualTo "200"
  KEYCHAIN Failure OR
    KEY "<RESPONSECODE>" EqualTo "401"
Converted IronBullet blocks:
  1. HttpRequest (POST to example.com/login)
  2. KeyCheck (Success on 200, Fail on 401)

​
OPK (OpenBullet 2) Import

Archive contents: 
config.opk/
  script.loli       # Main LoliCode blocks
  metadata.json     # Name, author, description
  settings.json     # Runner settings, proxy mode
  readme.md         # Optional documentation
LoliCode block syntax: 
BLOCK:HttpRequest
  LABEL:Login Request
  url = "https://httpbin.org/post"
  method = POST
  $"{\"email\":\"<input.USER>\",\"password\":\"<input.PASS>\"}"
  "application/json"
ENDBLOCK

BLOCK:Parse
  LABEL:Extract Email
  MODE:Json
  input = @data.SOURCE
  jToken = "json.email"
  => CAP @EMAIL
ENDBLOCK
Conversion mapping:
  • BLOCK:HttpRequest → BlockType::HttpRequest
  • BLOCK:Parse (MODE:Json) → BlockType::ParseJSON
  • BLOCK:Keycheck → BlockType::KeyCheck
  • => CAP @VAR → output_var: "VAR", capture: true

​
Unsupported Features

Some OpenBullet features don’t map directly to IronBullet:
OB FeatureIronBullet Alternative
C# code blocksRhai Script block (limited) or Plugin
LoliScript JUMP/LABELUse IfElse/Loop blocks
Selenium WebDriverBrowser automation blocks
TCP Raw socketTcpRequest block
Custom CaptchaSolverPlugin or Webhook

​
Security Scan

All imported configs are scanned for security issues: 
[Critical] Remote code execution risk
  Found system command execution in Script block
  Code snippet: Runtime.getRuntime().exec(...)

[Warning] Hardcoded credentials
  Found embedded API key in constant
  Code snippet: api_key = "sk_live_..."
Review and remove sensitive data before sharing configs.

​
Tips

Save imported configs as .rfx after fixing warnings. This preserves your changes and loads faster on next open.
Some OB2 LoliCode uses C# interpolation ($"string {variable}") which doesn’t work in IronBullet. Replace with <variable> syntax.
The importer is read-only. Original .svb/.opk files are never modified.

​
Troubleshooting

Import fails with “No blocks found”
  • Check file format (must be valid .svb/.opk/.loli)
  • Try opening in a text editor to verify it’s not corrupted
Variables show as undefined
  • Update <USER> → <input.USER> references
  • Check Data Settings separator matches your wordlist
Blocks execute but return wrong results
  • Review KeyCheck conditions (may need adjustment)
  • Check for unsupported string functions
  • Test in Debug mode with known-good data
