ZChat self-hosted is now DChat. Same product, same licence, new name - existing installs keep working.
Self-hosted support software
Free self-hosted live chat. Your server. Your data.
DChat is live chat with an AI agent built in, installed on your own server and backed by your own database: a visitor widget, agent dashboard, desktop console, offline forms, file uploads, webhooks and security hardening. The optional AI agent answers first from your own content, acts in your systems with the approvals you set, and hands visitors to your team with the conversation so far.

Complete chat toolkit
Run live visitor chat, offline messages, transcripts, departments, canned replies, file sharing, and agent assignment from your own server.
Agent dashboard
Give operators a focused console for active sessions, visitor context, transfer workflows, chat history, and support team visibility.
AI handoff ready
Use AI for first response automation while keeping the handoff path clear for human agents when a conversation needs judgment.
AI agent + human team
The AI agent is part of Premium and runs on the model you choose: OpenAI, Anthropic, or a local Ollama model, in which case its prompts and answers stay on your own infrastructure.
- Answers first from your help articles, a crawl of your website, and your PDF, Word and CSV files, with its sources linked under each answer.
- Takes real actions through your own HTTP endpoints; actions that change things wait for an agent's approval or the visitor's confirmation.
- Visual bot flows with a simulator - free; AI answer and AI action steps need Premium.
- Triages the inbox: labels, sentiment, priority, language, department or team, applied or only suggested.
- Hands off to a person with the bot conversation attached, and helps agents with suggested replies, summaries, rewriting and translation.

Who DChat fits
DChat is built for support teams, IT providers, agencies, and privacy-aware companies that want live chat to run from their own server and database.
Common use cases
Use DChat for pre-sales questions, customer support, internal service desks, private portals, AI-assisted first response, after-hours capture, and workflow automation.
Role workflows
Agents handle conversations, support leads monitor quality and activity, developers connect APIs and webhooks, and IT owners control hosting, backups, retention, and AI provider choices.
What is in the package
The current 46 MB download includes the ASP.NET Core server, dashboard assets, embeddable widget, SQL install scripts, documentation, and local runner helpers. No licence file: live chat is free.
Dashboard coverage
The dashboard covers live activity, agent management, conversation history, knowledge content, chatbot settings, webhook delivery, retention settings, and export paths.
Deployment and data control
- Live chat is free: unlimited agents and domains, no licence file, no expiry. Premium (AI assistant, roles, automation, extra channels) is optional, at $19 per agent per month.
- Install package includes the web application, database scripts, widget assets, and desktop agent tools.
- Designed for Windows or Linux hosting with ASP.NET Core and SQL Server.
- Keep chat records, visitor data, and operational controls inside your environment.
DChat vs hosted chat
DChat gives teams free self-hosted live chat, data ownership, flexible AI provider choice, and a deployment and database that stay under their control.
If you would rather not run a server at all, the same team builds ZChat (hosted AI chatbot) — a hosted service, billed per agent seat with the AI, inbox and human handoff already set up. Same problem, two deployment models: run DChat yourself for free, or let ZChat (hosted AI chatbot) host it.
Try it on your own hardware
Run the real package on your own hardware to validate the install, the support workflow and the self-hosting decision. Live chat stays free afterwards - unlimited agents, unlimited domains, no licence file.
Evaluation path
Three checks tell you whether DChat fits before production: can it run in your environment, can the team work in it, and does the self-hosted model match your policies?
The free package answers all three - it is the complete product, not a limited demo.
Evaluation download
Choose the deployment path, then take the full product with you: the server, browser dashboard, website widget, SQL scripts, and deployment helpers. No trial period and no card.
