Laudspeaker – open-source customer journey automation
Hey HN, excited to share our open source tool with the community. We wanted to build an open source omnichannel tool where you can design customer journeys with a drag and drop editor. You can use our tool for example to design an onboarding flow so that users who sign up to your site can receive a series of predetermined emails and sms. Give it a spin and let us know how we can improve it. We also made it so you can self host.
In plain words
Laudspeaker is an open-source tool for designing customer journeys across email, SMS, and other channels using a drag-and-drop editor. It enables businesses to automate workflows like user onboarding by creating sequences of predetermined messages. The platform can be self-hosted, giving users full control over their data and infrastructure. It's designed for developers and product teams building customer engagement systems.
