Chatwoot vs Plain
Side-by-side comparison of features, pricing, ratings, and alternatives.
Chatwoot is an open source customer support platform that unifies live chat, email, WhatsApp, Facebook, Instagram, Telegram, and LINE into a single agent inbox, positioning itself as an alternative to Intercom and Zendesk. It pairs the omnichannel inbox with a customizable knowledge base, so customers can self-serve before ever reaching an agent. Chatwoot layers AI on top with Captain, an assistant that learns from your help center and past conversations to automate responses, and Captain Copilot, which suggests answers and surfaces relevant history to human agents in real time. The core product is open source and self-hostable, with a managed cloud version and SOC 2 Type II compliance for teams that don't want to run their own infrastructure.
Plain is a customer‑support platform built for software companies that replaces ticket queues with real‑time, Slack‑style shared channels between support teams and customers. The experience feels like a conversation in a chat app, letting customers get answers faster and agents stay organized. The service integrates directly with existing Slack workspaces, supports rich media, and provides analytics to help teams improve response times and satisfaction. Plain is delivered as a cloud SaaS, with a subscription pricing model and an open API for custom workflows.
