Go Telegram Multibot

A scalable, multi-bot solution for Telegram using Go, GORM, and the Anthropic API.

Design Considerations

• AI-powered (Anthropic Claude)
• Voice message support (ElevenLabs STT + TTS) — optional, enabled per bot via config
• Supports multiple bot profiles
• Uses SQLite for persistence
• Implements rate limiting and user management
• Modular architecture
• Comprehensive unit tests

Usage

Docker Deployment (Recommended)

1. Clone the repository:

   git clone https://github.com/HugeFrog24/go-telegram-bot.git
   cd go-telegram-bot
   

2. Copy the default config template and edit it:

   cp config/default.json config/mybot.json
   nano config/mybot.json
   

Important

Keep your config files secret and do not commit them to version control.

3. Create data directory and run:

   mkdir -p data
   docker-compose up -d
   

Native Deployment

1. Install using go get:

   go get -u github.com/HugeFrog24/go-telegram-bot
   cd go-telegram-bot
   

2. Configure as above, then build:

   go build -o telegram-bot
   

Trying Out New Behavior Safely

Want to experiment with a different personality, tone, or set of instructions without disturbing the bot your users already talk to? Run a second, separate bot just for testing.

Each bot profile is its own config file with its own Telegram token, and bots are fully independent — separate identity, separate chat history, separate settings. So a "test twin" is quick to set up:

1. Create a new bot with @BotFather and copy its token.
2. Copy your existing config to a new file, e.g. cp config/mybot.json config/mybot-test.json.
3. In the new file, paste the new token, give it a different id, and edit system_prompts to try your changes.
4. Start it alongside your main bot. Chat with the test bot, tweak its prompt, and restart the test bot to try again — your real users never see the experiments.
5. Happy with the result? Copy the same change into your main bot's config and restart it.

Note

A test bot always needs its own token. Telegram only lets one running bot listen on a given token, so you can't point a second copy at your live bot — give the twin its own @BotFather bot instead.

Configuration

Each bot is one JSON file in config/ (see config/default.json for the template). Keys of note:

Key	Type	Default	Description
max_tokens	number	1000	Maximum output tokens per reply. Thinking tokens count toward this limit — raise it (e.g. 4000+) whenever thinking is "adaptive", or a turn can spend the whole budget on reasoning and produce no text.
thinking	string	(omitted)	Reasoning mode: "adaptive" (the model decides when and how much to think) or "disabled". Omit the key entirely to use the model's own API default. If the configured model doesn't support the chosen mode, the API rejects the request with a 400 — owners/admins see the raw error, regular users get the generic fallback. Check Anthropic's model docs for per-model support.
thinking_display	string	(omitted)	"summarized" or "omitted". Only valid together with "thinking": "adaptive". Controls whether the API returns a readable summary of the reasoning (logged, never sent to chat). Thinking is billed the same either way; when omitted, the API's per-model default applies.

Every reply logs one accounting line — [usage] model=... in=... out=... thinking=... stop=... — so thinking spend (billed even when its text is omitted) stays visible in journalctl/docker compose logs. A stop=max_tokens line is accompanied by an error-level warning that the reply was truncated.

Tip

For deep request/response debugging, the Anthropic Go SDK ships option.WithDebugLog(...) (dumps full HTTP bodies with auth headers redacted). It is not wired into the bot — dev-only, add it temporarily to the client constructor if you ever need wire-level traces.

Future: persistent memory

The Anthropic memory tool (memory_20250818) is a candidate future feature for cross-conversation recall (a self-hosted analog of ChatGPT's "memory"). The Go SDK already ships the types (BetaMemoryTool20250818Param and its tool-union slot plus the six-command union: view/create/str_replace/insert/delete/rename), but — unlike the Python/TypeScript/Java SDKs — provides no handler helper: the bot would have to hand-write client-side command dispatch against per-chat storage, including strict path validation (canonicalize and confine every model-supplied path under a fixed memory root; reject ../symlink traversal) and a no-secrets policy for stored content. Not implemented yet.

Systemd Unit Setup

To enable the bot to start automatically on system boot and run in the background, set up a systemd unit.

1. Copy the systemd unit template and edit it:

   sudo cp examples/systemd/telegram-bot.service /etc/systemd/system/telegram-bot.service
   

   Edit the service file:

   sudo nano /etc/systemd/system/telegram-bot.service
   

   Adjust the following parameters:

   • WorkingDirectory
   • ExecStart
   • User

2. Enable and start the service:

   sudo systemctl daemon-reload
   

   sudo systemctl enable telegram-bot
   

   sudo systemctl start telegram-bot
   

3. Check the status:

   sudo systemctl status telegram-bot
   

For more details on the systemd setup, refer to the demo service file.

Logs

Docker

docker-compose logs -f telegram-bot

Systemd

journalctl -u telegram-bot -f

Commands

Command	Access	Description
/stats	All users	Show global bot statistics (total users and messages)
/stats user	All users	Show your own message statistics
/stats user <user_id>	Admin/Owner	Show statistics for a specific user
/whoami	All users	Show your Telegram ID, username, and role
/clear	All users	Soft-delete your own chat history
/clear <user_id>	Admin/Owner	Soft-delete all messages for a user across every chat
/clear <user_id> <chat_id>	Admin/Owner	Soft-delete a user's messages in a specific chat
/clear_hard	All users	Permanently delete your own chat history
/clear_hard <user_id>	Admin/Owner	Permanently delete all messages for a user across every chat
/clear_hard <user_id> <chat_id>	Admin/Owner	Permanently delete a user's messages in a specific chat
/set_model <model-id>	Admin/Owner	Switch the AI model live without restarting

Note: In private DMs each user's chat_id equals their user_id. The scoped <chat_id> form is mainly useful for group chat moderation.

Testing

The GitHub actions workflow already runs tests on every commit:

However, you can run the tests locally using:

go test -race -v ./...

Storage

At the moment, a SQLite database (./data/bot.db) is used for persistent storage.

Remember to back it up regularly.

Future versions will support more robust storage backends.
