Olark alternative

A self-hosted Olark alternative with a built-in AI chatbot

Olark is a hosted live chat tool billed monthly per seat. DChat covers the same essentials, a website widget, a real agent workspace, transcripts and ratings, and adds a self-hosted AI chatbot, all as self-hosted software that runs on your own server, with conversations stored in your own database.

Free, not per-seat

A free, unlimited-seat edition replaces a monthly per-seat bill, so adding agents or handling more conversations does not raise your cost at all.

A built-in AI chatbot

Answer routine questions automatically from your knowledge base and hand off to a human when needed. Run the model locally with Ollama or use your own OpenAI or Anthropic keys.

Your data, your server

Transcripts and visitor records live in your own SQL Server database with CSV export and built-in GDPR access and erasure, not in a hosted service you rent.

Do I have to manage a server?

You host it yourself, but on infrastructure you likely already run: Windows with IIS, Linux with Nginx, or Docker, against a SQL Server database. The free localhost evaluation lets you try the whole thing on your own machine before setting up a real server.

Does it include the agent tools I expect?

Yes: a browser dashboard and a native Windows desktop console, canned responses, departments and routing, transcripts, and post-chat satisfaction ratings. Agents get native notifications for incoming chats rather than a tab that has to stay open.

How do I move over from Olark?

Install the server, run the SQL scripts, create your widget in the dashboard, and replace the Olark snippet on your site with the DChat one. Because you can rehearse it on localhost first, the switch on your live site is a single snippet change.

Run it on your server

Try the full product free on localhost.

The download is the real product: server, dashboard, widget and SQL scripts, with no licence file because live chat is free. One command sets up the demo database and opens the dashboard.

Self-hosted customer support software

Deploy live chat on your own terms, not on someone else's pricing model.

DChat gives you the installable server, web dashboard, website widget, and desktop agent tools in one self-hosted product, with live chat free to run, and an AI agent that answers, acts with the approvals you set and hands off to your team when you want one. Run it on infrastructure you trust, on the model you choose.

Deployment

Install on Windows or Linux, behind IIS or Nginx, in a VM, or in Docker if that fits your stack.

Commercial model

Live chat is free with unlimited agents. Premium, with the AI agent, is billed per agent per month, never per conversation.

AI Flexibility

Run the AI agent on a local Ollama model, or connect OpenAI and Anthropic with your own provider accounts.
