I’m looking for a small, no-frills tool that I can spin up on a Linux VPS and use to blast out a single message to every recipient listed in a CSV file. The workflow is simple: I upload the CSV, paste or type the message, press send, and watch the log as each username or user_id is processed. Core expectations • Runs headless on common Linux distros (Ubuntu/Debian preferred) • Leverages the unofficial Telegram API • Accepts CSV upload (one column of @usernames or ids) and sends the same text to each entry in sequence • Streams progress to stdout or a minimal web dashboard, then saves a completion report (sent / failed) to CSV or JSON Deliverables 1. Clean, well-commented source code 2. Step-by-step setup notes I can follow on a fresh server (Dockerfile or bash script welcome) 3. Brief usage guide showing the upload, message entry, and execution steps Nice-to-have but not required: proxy rotation, multi-account support, or an optional delay slider for safer throughput. Keep it lightweight, open-source, and ready for me to deploy without extra licensing.
