How Much RAM Does a Telegram Bot Need?

Discover how much RAM your Telegram bot actually needs, what drives resource usage, and which hosting plan is right for you.

How Much RAM Does a Telegram Bot Need?

A typical Telegram bot needs between 50 MB and 256 MB of RAM, depending on the language, framework, and whether it uses polling or webhooks. For most bots, 512 MB RAM provides a comfortable buffer for activity spikes.

Language Impact

Python (aiogram, python-telegram-bot): 50 MB to 150 MB at idle.

Node.js (Telegraf, node-telegram-bot-api): 80 MB to 200 MB. V8 garbage collection can cause brief spikes.

Go or Rust: Extremely lightweight, often under 30 MB.

Polling vs. Webhooks

Long polling uses continuous background CPU for API calls. Webhooks are more memory-efficient since activity only spikes when messages actually arrive, but require an HTTP server process to be running inside your bot.

Media Processing

If your bot processes files, resizes images, or converts audio, RAM usage will temporarily spike significantly beyond the baseline. A 5 MB image loaded into memory for processing may require 50 MB+ of RAM.

Recommended Hosting

Telegram Bot Hosting at VisiHost starts at Rs 10 per month (Spark plan, 512 MB RAM) on AMD EPYC processors and NVMe SSDs. This comfortably covers most Python and Node.js bots, ensuring sudden activity spikes do not crash your bot.
