Laudspeaker

Open-source customer engagement and product onboarding automation platform

Multi-channel messaging platform for event-triggered customer engagement. Build visual workflows, segment users, and send personalized push, email, SMS, and webhook campaigns at scale.

Overview

What is Laudspeaker?

Laudspeaker is a customer engagement and product onboarding platform designed for teams who need event-triggered, multi-channel messaging at scale. Built as an alternative to Braze, OneSignal, Customer.io, Appcues, and Pendo, it combines visual journey building with powerful segmentation and personalization capabilities.

Core Capabilities

The platform centers on a visual journey builder that enables teams to design complex, event-triggered workflows without code. Users can segment audiences by attributes, behaviors, and previous campaign interactions, then orchestrate messages across push notifications, email, SMS, and webhooks. A/B testing and Liquid templating support personalized messaging, while external API calls enable dynamic content customization.

With proven scalability—having delivered over 500 million messages—Laudspeaker is architected for high-volume use cases. The roadmap emphasizes data warehouse integration and modern data stack compatibility, ensuring teams maintain control over their data without vendor lock-in.

Current Status

Laudspeaker is in public beta, stable for most non-enterprise use cases. The platform continues active development with features like improved mobile push support, enhanced A/B testing, user timezone handling, and data warehouse syncing planned for upcoming releases.
