Zendesk

Freshdesk is a cloud-based customer support and helpdesk platform developed by Freshworks. It provides ticketing, multichannel support (email, phone, chat, social), automation, self-service portals, SLA management, reporting and integrations for businesses.

LibreDesk is an open-source, self-hosted omnichannel customer support desk distributed as a single binary. It combines live-chat and email conversations in one inbox, provides an embeddable website chat widget, and supports searchable multilingual help-center content. Its AI assistant answers live-chat questions using the knowledge base and hands conversations to a human when it cannot help; an agent copilot drafts replies, summarizes conversations, and retrieves knowledge-base answers. The system also provides event-based automations, capacity- or criteria-based assignment, SLA tracking, custom roles and permissions, CSAT surveys, analytics, macros, custom attributes, SSO through Google, Microsoft, or OIDC, HTTP/JSON APIs, webhooks, activity logs, and conversation search. It can be deployed through Railway or Docker, with PostgreSQL and Redis provisioned or configured for the deployment.

ResolveHQ is a Cloudflare-native, self-hostable helpdesk for small support teams. It provides a shared inbox with tenant-isolated customers, tickets, assignment, status, priority, tags, full-text search, team roles, email threading, attachments, saved replies, internal notes, reports, rule-based automations, and a public help center generated from knowledge-base articles. It runs as a single Cloudflare Worker that serves the REST API and React application through Hono. Cloudflare D1 stores tickets and customers, R2 stores attachments, Queues handle inbound and outbound mail jobs, and Email Routing delivers incoming mail. Outbound mail uses Resend by default, with an option on Workers Paid to use Cloudflare Email Sending. The system includes retries and recovery for stalled mail jobs, RFC 5322 thread handling, CSV report exports, and customer data export or erasure workflows. AI assistance for summaries, reply drafts, classification, and translation is optional and disabled until enabled per workspace. It can use Workers AI or OpenAI. The project can run on Cloudflare's Free plan for small deployments, subject to current platform limits, and requires a Cloudflare account and a domain on Cloudflare for Email Routing.

Chatwoot is an open-source, self-hosted customer support platform and omnichannel support desk. It centralizes conversations from website live chat, email, Facebook, Instagram, Twitter, WhatsApp, Telegram, Line, SMS, and other channels in a shared inbox, with tools for assignment, automation, labels, canned responses, teams, internal notes, contact management, segmentation, and reporting. It includes a Help Center Portal for publishing help articles, FAQs, and guides, and Captain, its AI support agent, which automates responses and handles common queries. The platform also provides integrations including Slack, Dialogflow, Shopify, Google Translate, and Linear, and is distributed as an open-source, self-hostable alternative to Intercom, Zendesk, and Salesforce Service Cloud.
