Laudspeaker: open-source alternative to Braze, Customer.io

About Laudspeaker

Laudspeaker is an open-source customer engagement and product onboarding platform. It was positioned as an alternative to tools such as Braze, OneSignal, Customer.io, Appcues and Pendo, and lets teams design product onboarding flows and send messages triggered by product events across several channels.

Its main features were a visual journey builder for complex workflows, a segment builder that targets users by attributes, completed actions and previous campaigns, multiple channels including push, email, SMS and webhooks, and A/B tests and personalization with Liquid templating and external API calls. It was built with NestJS, React and TypeScript, and planned to integrate with data warehouses and the modern data stack.

The README now states that Laudspeaker is no longer under active development or being supported. It mentions a Laudspeaker Cloud and a paid self-deployed enterprise plan, though availability is uncertain given that notice. The repository lists its licence as other. Anyone considering it should treat it as an archived project and check current status before building on it.
