What is LittleHorse?
LittleHorse is a developer-first platform designed to simplify the composition and automation of microservices, integrations, and workflows, particularly for leveraging Agentic AI. It allows developers to define business workflows using familiar programming languages (Java, Kotlin, Python, GoLang, C#) rather than a new Domain-Specific Language, promoting a "Business-as-Code" approach. This platform helps enterprises overcome the complexity of distributed systems and brittle connections, enabling faster adaptation to market conditions and quicker delivery of new capabilities.
The platform consists of several components: the LittleHorse Kernel for composing processes, Harness Connect for integrating with external APIs and systems, LittleHorse StreamSense for real-time event processing and insights, and Pony ID for workflow governance and monitoring. It emphasizes resilience with automatic retries, error handling, and Dead Letter Queues (DLQs), ensuring durable execution even during third-party outages. LittleHorse aims to provide a unified view for monitoring and debugging microservices, integrating human users, computer systems, and AI agents into cohesive workflows. It can be deployed on-premise via a Kubernetes operator or as a managed SaaS service.
