Telegram Bulk Checker: Full Guide to Open-Source Tool telegram_checker

Manually checking if Telegram usernames are taken is extremely inefficient when managing accounts or channels. The open-source tool telegram_checker is built for large-scale availability detection. Here's a deep dive into its core features:

🚀 Core Performance & Stability

Smart Status Detection: Accurately distinguishes between Available, Taken, Invalid, and Unknown errors, eliminating misjudgments.

High-Performance Concurrency Control: Uses shared semaphores and global request rate limiters. Supports FloodWait protection—when Telegram triggers rate limiting, all worker threads pause simultaneously to prevent system overload and crashes.

Resume & Crash-safe: Results are incrementally written. If interrupted, use the --resume parameter to skip already processed items and append the remainder, avoiding duplicate work.

🧠 Deep Data & Smart Suggestions

Rich Metadata: For taken channels/usernames, directly reads title, type, member count, description, last activity date, and verification status (e.g., Verified/Fake).

Username Generation Suggestions: Automatically generates and tests variants of taken names to find available alternatives.

Watch Mode: Periodically rechecks the list and reports only changed items—ideal for long-term tracking of specific accounts.

🛠️ Flexible Input & Output Security

Multi-Source Batch Processing: Supports command-line arguments, CSV/TXT files, or standard input (stdin) to adapt to different workflows.

Smart CSV Parsing: Automatically detects the username column without requiring a fixed schema. Compatible with name, @name, and https://t.me/name formats.

Diverse Output: Supports colored terminal cards, CSV, or JSON export; can filter to show only available names.

Injection-Proof Security: Automatically sanitizes CSV formula injection and terminal escape sequence attacks from hostile data like channel titles/descriptions, preventing data pollution.

💡 Use Cases

  • Bulk Registration: Quickly verify thousands of usernames for availability.
  • Channel Research: Deeply analyze member counts and activity of target channels.
  • Security Operations: Use resume functionality to ensure long detection tasks don't lose progress.
