Show HN: Open-Source TypeScript Framework for AI Agents – VoltAgent (voltagent.dev)

VoltAgent is an open-source TypeScript framework for building production-grade AI agents, paired with VoltOps, a framework-agnostic LLM observability platform. The stack provides unified APIs, memory and RAG support, function invocation, streaming responses, and quick provider portability (examples show OpenAI and Anthropic models). It includes a declarative Workflow Chain API for composing multi-step pipelines, supervisor/sub-agent orchestration for coordinated multi-agent systems, built-in integrations with 40+ apps, and deployment/debugging tools (visual flows, telemetry exporters such as Langfuse). Example APIs use @voltagent/core and provider SDKs to create, stream, and manage agents, while VoltOps surfaces traces and metrics to monitor agent behavior across tech stacks. For the AI/ML community this matters because it addresses two pressing gaps: productionization and observability of LLM-driven systems. VoltAgent reduces vendor lock-in by making model swaps a simple code change, standardizes agent patterns (memory, RAG, function calls) for repeatable enterprise workflows, and simplifies complex orchestration with supervisor agents and workflow chains. VoltOps tackles debugging and monitoring—critical for safety, auditability, and performance tuning—by exporting telemetry and visualizing agent flows. Overall, it’s a pragmatic, TypeScript-native toolchain that lowers engineering friction for deploying, iterating, and governing real-world agent applications.
