VoltAgent
Overview
Open-source TypeScript framework and engineering platform for building agents with memory, tools, workflows, RAG, guardrails, and observability.
VoltAgent is an AI agent engineering platform built around an open-source TypeScript framework. The framework is designed for building agents with memory, tools, RAG, guardrails, MCP support, voice capabilities, and multi-step workflows while retaining full code control. Its companion VoltOps Console supports production operations such as observability, automation, deployment, evaluations, guardrails, and prompt management, with cloud and self-hosted options referenced by the project. The GitHub repository is public and MIT licensed, while VoltOps offers paid plans in addition to developer/free access according to the official pricing page.
Product overview
Capabilities, pricing and fit
VoltAgent is agent-development infrastructure rather than one standalone agent. It combines an MIT-licensed TypeScript framework for agents, tools, memory, RAG, workflows, guardrails, voice, and multi-agent supervision with the optional VoltOps cloud or self-hosted operations console.
Information as of September 3, 2026
What it can do
- TypeScript agent runtime
Developers define agents with instructions, model providers, tools, memory, retrieval, guardrails, and direct or streamed generation methods, then expose them through application code or REST endpoints.[1], [2]
- Workflows and multi-agent supervision
The framework includes declarative multi-step workflows and supervisor coordination for teams of specialized sub-agents.[1]
- VoltOps operations layer
The optional console adds observability, automation, deployment, evaluations, guardrails, prompts, and managed RAG alongside the open-source runtime.[1], [3]
Where it fits best
Pricing and availability
The core framework is free and open source. VoltOps offers a $0 Developer plan, Core at $50/month, Pro at $250/month, and custom Enterprise pricing; Core and Pro include 14-day trials and metered limits or overages apply to several features.[3]
Platforms: TypeScript and Node.js applications, REST API, VoltOps web console[1], [2], [3]
Access: Self-managed open-source framework, VoltOps cloud, Enterprise self-hosted VoltOps[1], [2], [3]
Important considerations
- VoltAgent provides a framework and operations platform, not a finished task-specific agent; teams must implement instructions, tools, data connections, model access, and application interfaces.[1], [2]
- The free VoltOps Developer plan is limited to one seat, one project, 250 traces per month, seven-day retention, and small action, trigger, and RAG allowances.[3]
- Self-hosted VoltOps is reserved for the custom Enterprise offering rather than the public free, Core, or Pro tiers.[3]
