VoltAgent – Open-Source Observability-First TS AI Agent Framework
Hi HN, I'm founder of VoltAgent, a new open-source TypeScript-based framework for building AI agents. We know there are many frameworks out there. Our short story of why we built VoltAgent goes like this: We were developing an AI application ourselves. Initially, we tried existing frameworks. We also explored different flows using no-code tools. We noticed something interesting: the visual approach of tools like n8n made AI workflows much clearer and easier to understand. Building flows visually was neat and provided great visibility. However, we quickly ran into problems with no-code tools:…
In plain words
VoltAgent is an open-source TypeScript framework for building AI agents that prioritizes observability and visual clarity. It combines the code flexibility of traditional frameworks with the visual workflow visibility of no-code tools, allowing developers to maintain deep customization and integrate custom code without sacrificing clarity. The framework addresses the gap between rigid no-code platforms and opaque coding frameworks, designed for developers building AI applications who need both control and insight into their agent workflows.

Hi HN, I'm founder of VoltAgent, a new open-source TypeScript-based framework for building AI agents. We know there are many frameworks out there. Our short story of why we built VoltAgent goes like this: We were developing an AI application ourselves. Initially, we tried existing frameworks. We also explored different flows using no-code tools. We noticed something interesting: the visual approach of tools like n8n made AI workflows much clearer and easier to understand. Building flows visually was neat and provided great visibility. However, we quickly ran into problems with no-code tools: we felt locked in by their limitations, particularly the inability to customize deeply or integrate custom code the way we wanted. So, we returned to framework solutions. While frameworks gave us code control, we missed the clear visibility that visual tools provided. To achieve observability, we integrated standard AIOps tools (like LangFuse and LangSmith), but they didn't quite replicate the step-by-step execution clarity we'd seen in tools like n8n for understanding the flow itself. This gap led us to build VoltAgent for our own use. We shared it with developers in our network, received positive feedback, and decided to release it open-source. What VoltAgent Offers: - Core Building Blocks: It provides essential components for agents like tools, memory management, and state handling out-of-the-box. It's also LLM agnostic and supports multi-agent setups. - Visual Debugging Console: This is a key feature we built to address the visibility problem. You can connect it locally to your running agent (your data stays on your machine) to visually trace how the agent thinks step-by-step. You can inspect messages and see the execution flow, similar to how visual tools like n8n show workflows, but designed specifically for debugging agent execution written in code. You can find the code and documentation here: https://github.com/voltagent/voltagent We're actively developing VoltAgent, and our public roadmap is available here: https://github.com/orgs/VoltAgent/projects/1 We'd love to hear your feedback, suggestions, or any questions you might have.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
