Julep (by Julep AI) is an open-source platform that provides infrastructure for building stateful, production-ready AI agents and complex multi-step workflows. It positions itself as 'Firebase for AI agents', handling execution, scaling, retries, and state management automatically so developers do not need to provision or manage servers. The core primitives are Agents (persistent AI entities with long-term memory), Sessions (context-aware conversations that persist across interactions), Tasks (multi-step workflows with branching logic, loops, and parallel execution), and Tools (integrations with 100+ external services and APIs). Agents maintain conversation history and user preferences across millions of interactions without performance degradation. Julep supports most major LLMs, includes a built-in RAG pipeline for document retrieval, and offers adaptive context management. The serverless model means concurrency, load balancing, and fault tolerance are handled automatically. Developers interact via a Python or JavaScript SDK and a REST API. IMPORTANT STATUS: As of late 2025, Julep announced the shutdown of its hosted backend and dashboard effective December 31, 2025. The project remains open source and can be self-hosted. The Julep team pivoted focus to a new product called memory.store, a shared memory layer for AI tools and teammates. Julep also released a separate open-source project, open-responses, a self-hosted drop-in replacement for OpenAI's Responses API compatible with multiple LLM providers. Key features: - Stateful agents with persistent long-term memory across sessions - Multi-step task workflows with branching, loops, and parallel execution - Built-in RAG pipeline for document ingestion and retrieval - Serverless execution: automatic scaling, retries, and error handling - 100+ tool integrations (external APIs and services) - Support for most major LLMs via unified interface - Open source and self-hostable (hosted service shut down Dec 31 2025) - Python and JavaScript SDKs plus REST API
Hosted cloud service shut down December 31, 2025. Open-source self-hosted version is free. No current public pricing for a managed offering.
