About

Welcome to the official documentation for Octolin — the all-in-one LinkedIn data scraper and automation toolkit. Octolin enables recruiters, analysts, and business owners to extract and organize LinkedIn jobs efficiently, leads, and company data — all while navigating LinkedIn's blocking defenses, adhering to plan limits, and maintaining a smooth workflow with an intuitive interface.

Introduction

Octolin is a Windows-based LinkedIn job, company & lead scraper, distributed as a zip folder (octolin.exe file and relevant folders). It automates every step: logging in, scraping job and company data, collecting leads, handling anti-bot systems, and saving everything to Excel-ready CSV files.

  • Scrape LinkedIn job listings & details
  • Collect company data and 'About' info from company profiles
  • Extract leads: emails and phone numbers when available
  • Save all data to CSV (ready for Excel)
  • Manual login via browser + auto-save cookies
  • Pause/Resume scraping anytime
  • Sound notification on completion
  • Automatic login after the session logout pop-up
  • Automatic data autosave (with error prevention)
  • Scrape without login (for public listings)
  • Batch-based plan enforcement (quota per batch, live batch counter)
  • Transparent batch usage: see total and remaining right in the app
  • Randomized scrolling (distance and delay) for stealth
  • Settings for custom XPaths (both listing and detail)
  • Clear built-in instructions and simple GUI
  • Anti-blocking: proxies, user agent rotation, cache clearing
  • Persistent browser profile (udc_profile/) for session stability
  • All settings/config are GUI-editable

See updated prices at https://octolin.com/pricing

  • Demo mode: No license needed. Limit: 10 jobs/batch
  • Batch and quota usage is shown live in the About/Status area. Batch counter resets monthly (or with the billing cycle).
  • Release license option lets you transfer to another device with one click.

Scraping with Octolin

- Creating UDC Profile (One-Time Setup)

  • Click Settings — Enter LinkedIn Email & Password and Save Settings.
  • Click Login to Save Cookies — Chrome browser will open to complete the auto login process. You may also enter credentials manually here if you prefer.
  • Once logged in successfully, the browser window will close.

 

- Listing & Detail Scraping

  • Visit the LinkedIn website and search for your desired job keyword, apply filters, and copy the main page URL
  • Click Listing Scraper — Inside Octolin, paste your LinkedIn job search URLs into the input page of Listing Scraper.
  • Click Start — Octolin extracts job URLs up to your plan’s batch quota.
  • Each batch is counted only when a new group is scraped. Unused quota does not roll over.
  • Data is saved to a uniquely named CSV (e.g., Linkedin-Jobs-Listing (1).csv).
  • Click Detail Scraper - Inside Octolin, Upload/paste this scarped data file containing job URLs to extract full details (job description, recruiter info, contact, etc.).
  • Quota and batch limits apply to detail scraping (as per your plan/demo).
  • Data auto-saves to the same/fresh CSV.

 

- Batch Limits

  • Server-enforced for security.
  • Monthly batch limit: scraping is paused when exhausted, and auto-resumes on the next cycle.

 

- Demo Mode

  • No license required.
  • Scrape up to 10 jobs per batch.
  • App UI switches to "Limited Mode" (yellow badge) in demo/quota-exceeded mode.

Anti-Blocking & Stealth Features

Octolin’s advanced anti-blocking and automation stack keeps you scraping, even under LinkedIn’s defenses:

 

  • Login with Cookies: Save/load LinkedIn session via browser cookies for frictionless login.
  • Encrypted Passwords: Store your LinkedIn password (optionally) in encrypted form for one-click auto-login.
  • Manual & Auto Login: Use browser for manual login or enable credential-based automation.
  • Auto login on logout popup: Regain session automatically when LinkedIn logs you out.
  • Proxy Support & Rotation:
  • io proxy integration for automatic rotation
  • PAC file support
  • User-Agent Rotation:
  • Use a pool of browser user agents (rotated randomly)
  • JS spoofing for maximum stealth
  • Periodic Cache Cleaning:
  • Automatic browser cache and cookie clearing between jobs (threaded)
  • Keeps LinkedIn tracking at bay
  • Scrolling Stealth:
  • Randomized delays and scroll distances to mimic real user activity
  • GUI-linked config saving: Change all XPaths, delays, proxies, and settings from the GUI — no file editing required
  • Persistent Profiles: All Chrome/LinkedIn session data is stored in udc_profile/ for stable, resume-able scraping
  • Auto-save data: Autosave runs in a background thread (safe: never crashes if file is closed)
  • Sound Notification: Audio alerts on scrape complete
  • Pause/Resume: Safely pause or resume scraping jobs
  • Lead Collection: Automatically extracts emails/phones from job and recruiter fields when available

Troubleshooting & Error Handling

  • Quota/Limit Warnings:
  • Yellow badge/“quota reached” means wait until next batch, or upgrade your plan.

 

  • Login Issues:
  • Use “Login and Save Cookies” in the GUI, or set credentials for auto-login.
  • Check proxy/anti-block settings if login fails or stalls.

 

  • Server Not Reachable:
  • Ensure firewall/AV allows Octolin, and internet connection is stable.

 

  • Browser Won’t Start:
  • Confirm Chrome is installed and updated.
  • Undetected_chromedriver must match your Chrome version.
  • If browser is left open from previous batch run, close it manually.

 

  • Clear Log Prints:
  • All debug log prints can be toggled off for production/clean output.
