About Chatstack
What is Chatstack?
Chatstack is a self-hosted live chat software built with PHP and MySQL. It lets businesses communicate with website visitors in real time, helping to improve customer service and increase conversions. Because it's self-hosted, you own your data and have full control over your chat environment.
Who is it for?
Chatstack is ideal for small to large businesses that want a cost-effective, no-subscription live chat solution. It's especially suited for companies that prefer to keep their data on-premises or want a one-time payment instead of recurring fees. It's not for businesses that need a fully managed, cloud-hosted chat service without any server setup.
