In simple English
This tool adds a customer chat box to your web app. It uses artificial intelligence to answer common questions from your users. You can host it on your own server to keep your data private. The software is free for non-commercial use under an AGPL-3.0 licence. You need technical skills to set it up and run it.
What it is
Cossistant is an open-source customer support platform and React chat widget. It features customizable AI support agents and backend infrastructure built with TypeScript.
What it is good for
Solo developers building software-as-a-service who want an embedded support chat with automated answers without paying for a hosted service.
- Complete control over your support data by running it on your own server.
- Includes React components and Next.js bindings for quick integration.
- Built-in artificial intelligence agents answer user questions automatically.
- Requires Docker (a way to run a program inside its own sealed box, so it cannot break anything else on your server), PostgreSQL (a database system to store information), and Redis (an in-memory data store for speed) to run the backend.
- The AGPL-3.0 licence requires you to share your source code if you modify the software and let people use it over a network.
- Commercial use requires purchasing a separate licence from the authors.
