# CanWeChat

> Website live chat for one site. Visitors message from a ~12KB widget; teams reply from the CanWeChat inbox, Slack, Discord, or Telegram.

CanWeChat is built for SaaS and marketing sites that want real human replies without a heavy helpdesk. One website per workspace, one active reply destination, signed webhooks, and a Cloudflare Workers stack.

## Blog

- [Why the CanWeChat widget is ~10 KB and not a React app](https://canwechat.dev/blog/why-we-built-a-10kb-widget): Host pages should not download your dashboard. CanWeChat’s public widget is vanilla TypeScript in a Shadow DOM, not a React island.
- [Webhooks without trusting the checkout redirect](https://canwechat.dev/blog/webhooks-without-trusting-redirects): Billing state comes from Dodo Payments events, not a success URL. The same rule applies to Slack, Discord, and outbound webhook relays.
- [Slack setup without the maze](https://canwechat.dev/blog/slack-setup-without-the-maze): Connect a bot, pick one channel, and reply in-thread. You do not need a helpdesk workspace to answer site visitors from Slack.
- [Build vs buy for live chat on a marketing site](https://canwechat.dev/blog/build-vs-buy-live-chat): A custom WebSocket widget looks cheap until you own auth, spam, retries, and presence. Buy the narrow product; keep your brand site light.
- [Webhook retries that actually land](https://canwechat.dev/blog/webhook-retries-that-actually-land): Signed delivery, bounded response snippets, and a queue beat fire-and-forget. Your CRM should see the same event twice safely.
- [Installing the CanWeChat widget in a Next.js app](https://canwechat.dev/blog/nextjs-widget-install): Load the script once in the root layout, lock your domain, and call identify after auth. No React wrapper required.
