Can I vibecode Intercom?

KINDA· weekend project

A chat bubble, a shared inbox and email replies for a single website is a weekend: a widget script, a WebSocket server, an agent page and SMTP plus IMAP for the email side. Past that the gaps are real: inbound mail that threads correctly, spam, WhatsApp and SMS carriers, and the resolution rate of Fin, which depends on retrieval tuning and testing a prompt won't match. Chatwoot already covers chat plus inbox as free software, so build your own only if you want something much smaller.

Claude Code, Codex or CursorAny of them can run the prompt.
Node.js 22better-sqlite3 compiles a native module, so build tools must be installed.
A support mailboxSMTP for sending and IMAP for reading replies, on a domain where you can set SPF and DKIM.
A public HTTPS addressA small VPS or a tunnel; your site loads the widget from it.
Help articles as MarkdownUsed for suggested answers; a handful is enough to start.

Before you buildIntercom has no free plan, only a 14-day trial. Chatwoot already does chat and inbox for free: build only if you want something smaller than it.

1. Install one agent: Claude Code, Codex, Cursor.
2. Make an empty folder and open it in the agent.
3. Paste the prompt below, press enter, and answer its questions as it builds.

The prompt

Build me a small support chat and inbox to replace Intercom. Requirements:

- Node.js 22 + TypeScript: a Fastify server with `@fastify/websocket`, one SQLite file via
better-sqlite3 at ./data/support.db, and a vanilla TypeScript widget bundled by esbuild into
/widget.js. `npm start` serves http://localhost:4700.
- Widget: one script tag (`<script src="https://HOST/widget.js" data-site="SITE_KEY">`) draws a
chat bubble in a shadow DOM. The visitor gets a random id in localStorage, can leave an email,
and sees the history after a reload. Follow prefers-color-scheme and stay under 30 KB gzipped.
- Storage: sites (key, name, allowed origins, accent colour, office hours), visitors,
conversations (open, snoozed, closed) and messages (author visitor, agent or system; body;
created_at). Reject widget connections whose Origin is not in the site's allowed origins.
- Inbox at /admin (one password in .env, signed cookie): conversation list with unread counts,
live updates over WebSocket, reply box, canned replies from a Markdown file triggered by
/shortcuts, internal notes, snooze, close and desktop notifications.
- Email: when a visitor left an address and is offline, send the reply through nodemailer SMTP
with the conversation id in the subject; poll an IMAP mailbox with `imapflow` every 60 seconds
and add replies to the right conversation. Outside office hours show a configurable away note.
- Help answers: index ./help/*.md with SQLite FTS5. For each new visitor message show the agent
the 3 best-matching articles and, if LLM_BASE_URL is set in .env, a drafted reply
(OpenAI-compatible; Ollama works). A draft is never sent without a click.
- Safety: escape all message HTML, limit each visitor to 20 messages a minute and 2,000
characters per message, no file uploads.
- One team, one agent login. No accounts, no telemetry. Outbound calls: SMTP, IMAP and the
optional LLM endpoint.
- Out of scope: WhatsApp, SMS, phone, tickets, workflows, product tours, reports, several agents.
- README: embedding the widget, SPF and DKIM for the sending domain, and exposing the server over
HTTPS.

Opens your agent with the prompt filled in, you press enter. Or copy it and paste it into an empty folder.

Then keep going

Next prompts, same folder.

The first prompt builds the core. Run these one at a time in the same folder to grow it into your own Intercom.

Add Telegram notifications to the support chat in this folder. Requirements:

- TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID in .env. Each new conversation and each visitor
  message posts a short message with the first 200 characters and a link to /admin.
- Replying to that Telegram message sends the text to the visitor as an agent message.
- Ignore messages from any chat id other than the configured one.
- Out of scope: Telegram groups, buttons and media.
- Update the README with how to create the bot.

Add visitor context to the support chat in this folder. Requirements:

- The widget sends the current page URL, referrer and language with each conversation, shown
  in the inbox sidebar next to the visitor's history.
- A logged-in user can be identified by a signed token from your server: `window.Support
  .identify(token)` where the token is an HMAC-SHA256 JWT with email and name, verified with
  IDENTITY_SECRET in .env.
- Identified visitors merge with earlier anonymous conversations that used the same email.
- Show country from the Cf-IPCountry header when present; store no IP addresses.
- Update the README.

Add a contact importer to the support chat in this folder. Requirements:

- A script `npm run import-contacts -- <file.csv>` that reads the CSV Intercom emails from
  Contacts > More > Export users.
- Read the header, print the proposed mapping for name, email and created date, and ask for
  confirmation before writing anything.
- Create visitors for rows with an email, skip duplicates, and print imported and skipped counts.
- Update the README with the export steps and a reminder that the download link expires after
  one hour.

Add a small stats page to the support chat in this folder. Requirements:

- A page at /admin/stats with conversations opened and closed per day for the last 30 days,
  median time to first reply and median time to close, computed in SQL.
- Count office hours only when computing reply times.
- A table of the 10 slowest conversations with links to them.
- No chart libraries: plain SVG.
- Update the README.

What you lose

WhatsApp, SMS, phone and social channels in the same inbox
Fin, an AI agent that resolves conversations without a person
Workflows, round-robin assignment, SLAs and team inboxes
Proactive messages, product tours, surveys and banners
Reports on volume, response time and satisfaction
A hosted, multilingual help center

Why people still pay

Support teams pay for one place where chat, email and the AI agent share a single conversation history, run by someone else. Fin is a draw for many, since its pricing charges only when it resolves a conversation.

Estimate · A $5 VPS carries one small site, plus a domain if you don't have one. Drafted answers add pennies per message through an API, or nothing with a local model. The build is token usage on your agent plan.

Leaving Intercom

Take your data, then cancel.

1 · Take your data out of Intercom

1Single conversations and bulk selections (200 to 300 at a time) export from the Inbox as text or PDF; internal notes are excluded from transcripts.
2A saved Inbox view can be downloaded as CSV (up to 100,000 rows) but holds the visible columns and a link, not the message text. Reports > Dataset export gives metadata only, 10,000 rows per browser download.
3For full message content at scale use the Conversations API, or the Amazon S3 JSON export (up to two years of history). Neither can be imported into another Intercom workspace.
4People: in Contacts, select users, open More and export. The CSV is emailed and its link expires after one hour.
5Help center articles have no export in the app; Intercom's own help points developers to the Articles API.

2 · Cancel Intercom

1Open Settings > Subscription > Billing and choose Payment details at the top.
2Scroll down and click Cancel subscription.
3Contract customers must instead contact their account manager and give written notice at least 30 days before renewal.

You keep access to the end of the billing period. Your data isn't deleted at cancellation, but you can't reach it after the subscription ends unless you restart.
There is no pause option: cancellation is the only way to stop billing.
Annual subscriptions are paid upfront and aren't refunded pro rata if cancelled early; to ask for a refund, cancel first, then contact support.
Outbound messages and the help center pause automatically when the plan ends, so move the help articles and the widget before that day.
