FlowCastle vs n8n

TL;DR

n8n is built to connect apps and automate back-office work. A Telegram bot is one of many things it can do, and a simple one is quick to build. FlowCastle is built for the conversation itself: menus, questions that wait for an answer, a contact list, broadcasts, hosting. If your bot mostly talks to people, build it in FlowCastle. If your work is mostly between systems, keep it in n8n. Most teams that have both needs should use both: the bot in FlowCastle, the automations in n8n, one HTTP call between them.

The n8n facts on this page come from a bot we built on n8n 2.42.6 in October 2026 and from n8n's own docs and pricing page, checked the same month. The build is written up step by step in How to Build a Telegram Bot With n8n.

At a glance

Both tools count every incoming message and every button tap. n8n calls it an execution, FlowCastle calls it an automation event. In FlowCastle, AI answers also use credits, and 100 a month are included.

Where n8n is the better choice

n8n is a strong tool, and for a lot of work it is the right one:

• Your work is between systems, not with people. Syncing a CRM, moving rows between sheets and databases, scheduled reports, cleaning up data. n8n has an integration for most apps you use. FlowCastle does not try to be that.
• You want to self-host. n8n runs on your own server, so your data stays with you. FlowCastle is a managed service only.
• The Telegram part is small. Alerts from your systems to a chat or a channel, a single command that returns one answer, or a menu with a few buttons. n8n does these in a handful of nodes.
• You need an AI agent that uses tools across many apps. n8n's AI Agent node plugs into the same integrations as the rest of n8n.
• Your team already lives in n8n. One more workflow is cheaper than one more tool.

Where FlowCastle is the better choice

• Dialogs with more than one step. n8n runs each Telegram message on its own, so the bot does not know which question it just asked. You have to store that state in a table and check it at the top of the workflow. In FlowCastle, a message can wait for a reply and save it to a variable.
• Menus people can move around in. A Back button in FlowCastle returns the person to the screen they came from. In n8n, Back is another branch where you rebuild the previous menu by hand.

• A contact list you did not have to build. Everyone who starts the bot is saved as a contact with their answers. You can tag people, filter them and send broadcasts. In n8n you design that table, fill it on every message and write the sending loop yourself.
• No server and no webhook juggling. You paste the bot token and publish. With n8n you either pay for n8n Cloud or run an always-on server with HTTPS. Telegram also keeps one webhook per bot, so in n8n a bot is either being tested or live.
• People who are not developers can change the bot. The canvas shows messages and buttons, not expressions like $json.callback_query.data.

Use both

This is the setup we would pick for a business that already has n8n.

The bot runs in FlowCastle and holds the conversation. When it has something worth sending, such as a qualified lead, a booking or an order, an External Request step posts it to a Webhook node in n8n. From there n8n does what it is good at: adds the row to the CRM, notifies the team, creates the invoice. The n8n workflow no longer needs a Telegram trigger, a state table or keyboards, and it runs once per lead, not once per tap.

It works in the other direction too. A FlowCastle flow can start from an incoming webhook, so an n8n workflow can trigger it. Inside a flow, a code step can also call any API directly when a full n8n workflow would be too much.

FAQ

Is FlowCastle a replacement for n8n? No. FlowCastle replaces the Telegram bot part of an n8n setup: the trigger, the menus, the conversation state and the contact list. It does not replace n8n's integrations or scheduled automations.

Can I connect FlowCastle to n8n? Yes. Add an External Request step in the flow and point it at the URL of an n8n Webhook node. Send the answers the bot collected as JSON. To go the other way, start a FlowCastle flow from a webhook and call that URL from n8n.

Is n8n free for Telegram bots? The self-hosted Community edition has no licence fee, but Telegram only delivers messages to an HTTPS address, so you need an always-on server, a domain and a certificate. On n8n Cloud the Starter plan was €20 a month billed annually with 2,500 executions when we checked in October 2026, and every message and button tap is one execution.

Which one is easier for an AI Telegram bot? For a private AI chat, n8n's AI Agent with a memory node works well and takes five nodes. For a customer-facing bot that mixes AI answers with menus, forms and a handoff to a person, FlowCastle is less work because those parts are already there. Our AI support bot guide shows that setup.

Does n8n have a Telegram bot template? Yes, n8n's template library includes Telegram workflows. We also share the two workflows from our test build as files in the n8n Telegram bot tutorial.
