VoltAgent

VoltAgent is an end-to-end AI agent engineering platform that combines an open-source TypeScript framework with the VoltOps cloud console for observability, automation, and deployment. Built by the team behind Refine, it brings clarity and best practices to JavaScript AI development — filling a gap left by Python-dominated tooling. The platform supports everything from single-agent prototypes to enterprise-scale multi-agent systems, with full TypeScript type safety and Zod schema validation throughout.

• Open-Source Core Framework: Install via npm create voltagent-app@latest to scaffold a production-ready TypeScript agent with built-in support for Memory, RAG, Guardrails, Tools, MCP, Voice, and Workflow.
• Multi-Agent Orchestration: Define a Supervisor Agent with subAgents to coordinate specialized agents, each with their own LLM, tools, and memory, enabling complex reasoning pipelines.
• Workflow Chain API: Use createWorkflowChain() with .andAll() and andAgent() to compose declarative, fully-typed multi-step agent workflows with pause/resume support for human-in-the-loop scenarios.
• VoltOps Observability Console: Connect your agents to the VoltOps console to monitor LLM calls, trace agent behavior, run evals, manage prompts, and debug workflows in real time — available as cloud or self-hosted.
• RAG Integration: Use .embed(), .query(), and .rerank() APIs to build knowledge bases backed by vector stores like Pinecone, Postgres, and Supabase, with support for OpenAI, Cohere, and Voyage embeddings.
• Triggers & Actions: Configure event-driven triggers (e.g., Slack messages, webhooks) to automate agent workflows across 40+ integrations including GitHub, Gmail, Salesforce, Jira, and Stripe.
• Unified LLM Provider API: Switch between OpenAI, Anthropic, and custom LLMs with a single line change, using the @ai-sdk adapter pattern.
• Prompt Management: Version and iterate prompts directly in the VoltOps console without redeploying code, enabling rapid experimentation and A/B testing.
• Deployment: Deploy agents to production with persistent tunnel URLs, basic auth, and self-hosted options available on higher-tier plans.
