Best Open Source Telegram Bots (2026): Self-Host and Customize

Open source Telegram bots offer something that hosted services cannot: full control. You own the code, you choose where it runs, you decide what data is logged, and you can modify any behaviour to fit your needs. For communities with privacy requirements, developers who want to learn from production-quality code, or anyone who needs a feature the public bot does not offer, self-hosting is the answer. This guide covers the best open source Telegram bots across group management, AI, and download tools — and walks through how to get one running. Browse the Open Source Telegram Bots collection and Developer Tools category for more.

Best Open Source Group Management Bots

1. Rose Bot — Full-Featured Moderation Suite

Rose (also known as MissRose in its hosted form) is one of the most capable open source group management bots available. The codebase is written in Go, making it fast and memory-efficient — a single instance handles thousands of groups without strain.

Features included:

  • Warn system with configurable warn limits and automatic kick/ban
  • Ban, kick, mute, and unmute with optional time limits (timed bans/mutes)
  • Anti-spam: flood control, message rate limiting
  • Filters: keyword-triggered automated responses or actions
  • Notes: save and retrieve formatted text snippets via commands
  • Welcome and goodbye messages with button support
  • Admin management: promote/demote, anonymous admin mode
  • Federation system: share ban lists across multiple groups
  • Locks: restrict specific message types (links, stickers, GIFs) group-wide
  • Reporting: /report command that pings all admins

Self-hosting: Rose requires Go 1.21+, a PostgreSQL database, and a Redis instance. The repository includes a Docker Compose file that brings up all dependencies with a single command. Configuration is handled via a YAML config file or environment variables.

Repository: github.com/PaulSonOfLars/tgbot-rs (Rose bot)

2. Ptb-Admin — python-telegram-bot Admin Template

For Python developers, Ptb-Admin is a well-structured open source admin bot template built on python-telegram-bot. Rather than a finished product, it is a starting point — a clean codebase demonstrating best practices for command routing, database integration (SQLAlchemy), Docker deployment, and admin permission checking. Fork it, add your community's specific rules and features, and deploy in a day.

3. Telegram-BotKit (Node.js)

A TypeScript group management template built on grammY. Includes ban/kick/warn commands, conversation state management via grammY sessions, PostgreSQL integration with migrations, and a web admin dashboard for group settings. Actively maintained and a good learning resource for grammY's plugin ecosystem.

Best Open Source AI Bots

4. ChatGPT-Telegram-Bot

The most starred open source project in the Telegram bot ecosystem connects OpenAI's API to Telegram. Users send messages; the bot forwards them to GPT-4o (or any configured model) and returns the response. The key advantage over the official ChatGPT app is Telegram's native interface and the ability to run the bot in groups where multiple members share a single API key.

Features in the most popular forks:

  • Conversation history: maintains context across messages within a session
  • System prompt configuration: set a custom persona via environment variable
  • Image generation: /image [description] calls DALL-E 3
  • Voice message transcription: Whisper API converts voice notes to text before sending to GPT
  • Per-user token budgets: limit how much API credit each user can consume
  • Admin-only mode: restrict bot usage to specified user IDs
  • Stream responses: words appear progressively rather than waiting for the full response

Deployment: Requires an OpenAI API key. Runs on any VPS with Python 3.11+, or on Railway/Render with one-click deploy buttons provided in most forks. No database required for basic operation; add Redis for persistent conversation history.

5. LocalAI-Telegram-Bot

For those who want AI capabilities without sending data to OpenAI, LocalAI-Telegram-Bot connects Telegram to LocalAI — a self-hosted inference server compatible with the OpenAI API format. Run LLaMA 3, Mistral, Phi-3, or any supported model locally; the Telegram bot is the interface. This setup is entirely air-gapped — no data leaves your infrastructure.

Hardware requirements are significant (a GPU with 8–16 GB VRAM for usable performance), but for organizations with privacy constraints or high API cost concerns, self-hosted inference eliminates both problems.

Best Open Source Download Bots

6. yt-dlp Telegram Bot

yt-dlp is the gold standard command-line video downloader, supporting over 1,000 sites. Several open source Telegram bot wrappers expose yt-dlp through a Telegram interface: users send a URL, the bot downloads it via yt-dlp, and returns the file. The wrappers add queue management, format selection menus, progress reporting, and Telegram file size handling.

What a self-hosted yt-dlp bot enables:

  • Download from YouTube, Instagram, TikTok, Twitter/X, Reddit, and 1000+ other sites
  • Format selection: MP4 at various resolutions, MP3 audio extraction
  • Playlist support: download entire playlists with a single URL
  • Subtitle download: extract subtitles as SRT files
  • No rate limiting imposed by third-party services
  • Your own infrastructure means no queuing delays from shared public bots

Self-hosting requirements: Python 3.8+, yt-dlp installed, ffmpeg for format conversion, a Telegram bot token. Runs on any VPS; storage considerations apply for large downloads.

7. Telegram-RSS-Bot

A simple but endlessly useful open source bot that monitors RSS feeds and posts new items to Telegram chats or channels. Configure feeds via commands; new articles arrive as formatted Telegram messages with title, summary, and link. Self-hosting gives you unlimited feeds and full control over post formatting.

How to Self-Host a Telegram Bot

The general process for any open source Telegram bot:

Step 1: Get a Bot Token

Message @BotFather on Telegram → /newbot → follow prompts → copy the API token.

Step 2: Set Up a Server

A VPS with 1 vCPU and 1 GB RAM is sufficient for most group management and utility bots. Providers like Hetzner (from €4/mo), DigitalOcean ($6/mo), and Vultr ($6/mo) are popular choices. For Python or Node.js bots, Ubuntu 22.04 LTS is a reliable base.

Step 3: Clone and Configure

git clone https://github.com/example/the-bot-repo
cd the-bot-repo
cp .env.example .env
nano .env  # Set BOT_TOKEN and other required variables

Step 4: Install Dependencies

# Python
pip install -r requirements.txt

# Node.js
npm install

# Go
go build -o bot .

Step 5: Run and Keep Alive

# Using systemd (recommended for production)
sudo nano /etc/systemd/system/mybot.service

# Service file content:
[Unit]
Description=Telegram Bot
After=network.target

[Service]
User=ubuntu
WorkingDirectory=/home/ubuntu/the-bot-repo
ExecStart=/usr/bin/python3 main.py
Restart=always

[Install]
WantedBy=multi-user.target

sudo systemctl enable mybot
sudo systemctl start mybot

For Docker-enabled repositories, the entire stack (bot + database) typically runs with docker compose up -d.

FAQ

Is it difficult to self-host a Telegram bot?

For bots with Docker Compose configurations, it is straightforward — often under 30 minutes from clone to running. For bots requiring manual dependency setup and database migrations, expect 1–2 hours. Basic Linux command line comfort is sufficient; advanced sysadmin knowledge is not required for most bots.

What are the main costs of self-hosting?

Primary cost is the VPS: €4–10/month for a small server handles most group management and utility bots. For AI bots calling external APIs, the API cost (OpenAI charges per token) is the dominant cost. For self-hosted AI inference, GPU hardware or GPU cloud rental is the significant expense.

Can I self-host a bot on a shared hosting plan?

Only for PHP webhook bots. Python, Node.js, and Go bots require persistent processes that shared hosting does not support. A cheap VPS is necessary for anything other than PHP.

How do I keep my self-hosted bot updated?

Watch the upstream repository for updates (GitHub's "Watch" → "Releases only" notification option). When an update is available: git pull, reinstall dependencies if requirements changed, restart the service. For critical security patches, update promptly.

What are the risks of self-hosting?

Primary risks: server downtime means bot downtime (no SLA), security responsibility falls on you (keep the OS and dependencies updated), and backups must be managed manually. For community-critical bots, set up monitoring (UptimeRobot or similar) to alert you when the bot goes offline.
