DENKOPS

Telegram bot hosting

Telegram bot hosting that never sleeps.

A Telegram bot has to answer when someone messages it, at 3 in the afternoon or 3 at night. Free tiers that sleep, functions with cold starts and laptops that close all show up as a bot that does not reply. A DenkOps slot keeps your bot running.

Webhook or long polling, both work

  • Webhook. Telegram calls your bot's HTTPS URL for every update. DenkOps gives every project an HTTPS URL, so setWebhook points straight at it.
  • Long polling. Your bot keeps a connection open and asks Telegram for updates. That needs a process that never stops, which is exactly what a slot is.

What a bot usually needs

  • The bot token as a secret. Store BOT_TOKEN as an environment variable. Your coding agent can set it without the token ever being written into code or chat logs.
  • State between messages. Conversations, user settings and queues go on the durable /persist disk or the key-value store in @denkopsai/sdk, and survive redeploys.
  • Scheduled messages. Daily digests and reminders run as managed cron jobs from denkops.json.
  • Locked-down outbound traffic. Allow api.telegram.org and the APIs your bot calls; everything else is blocked by default.
  • Logs. When the bot stops answering, ask your agent to read the logs and fix it.

FAQ

Can I host a Telegram bot for free?

Yes. One project is free with no credit card, and the slot is always on, so the bot does not fall asleep.

Should I use a webhook or long polling?

Either works on DenkOps. Webhooks are the usual choice because every project has an HTTPS URL; long polling works because the slot is a process that keeps running.

Where do I store the bot token?

As an environment variable on the project. It is available to your code and is not shown in logs or uploads.
