4 Must‑Try AI Agent Frameworks and Tools

1. OpenHanako: a personal AI assistant with “eyes” and “hands”

OpenHanako is a graphical personal AI Agent with memory, personality, proactive actions, and multi‑Agent collaboration.

Memory system – remembers everything you say, especially recent events.

Personality shaping – each Agent can have a distinct speaking style via templates and custom files.

Multi‑Agent collaboration – create multiple Agents with independent memory and personality that can chat and delegate tasks.

Secure sandbox – dual isolation with PathGuard four‑level access control and OS‑level sandbox.

It integrates Telegram, Feishu, QQ, and WeChat bots, allowing you to talk to the Agent on WeChat and let it operate your computer remotely.

The key is a full desktop GUI built with Electron, not just a CLI.

2. Awesome Open‑Source AI: curating truly usable AI projects

Many GitHub projects are labeled AI but merely wrap closed‑source APIs. Awesome Open‑Source AI only lists projects that are genuinely open‑source, self‑deployable, and modifiable.

Projects are categorized by use case (AI coding tools, Agent frameworks, model deployment, data processing, computer vision, speech, etc.) and each entry shows license, tech stack, and deployment method.

It currently indexes over 3,800 starred projects, with ongoing community contributions.

3. Vercel Workflow: adding a persistent brain to your AI Agent

Vercel’s Workflow SDK lets you build durable, highly reliable multi‑step workflows in TypeScript.

It solves the problem of step failures or network interruptions when an AI Agent calls multiple tools: each step has state, can be recovered, and retried.

Typical use case: user uploads a PDF → extract content → call model → generate report → send email, with guarantees for each stage.

4. Google ADK for JS: Google’s official Agent development framework

Google’s TypeScript Agent Development Kit (ADK) provides a code‑first framework for Node.js and browsers.

It offers full type‑safe definitions of Agent behavior, tools, and orchestration logic; tool parameters are validated with Zod v3/v4 at compile time.

Runs in browsers and servers; supports ESM, CommonJS, and web bundles.

Built‑in tools: Google Search, Google Maps, Vertex AI Search, etc.

Multi‑Agent orchestration: sequential, parallel, loops, routing.

A2A protocol for delegating to remote Agents.

CLI tool and web debugging UI.

For developers in the Google AI ecosystem, ADK is the most direct way to integrate models such as Gemini.

These four projects cover different layers of AI Agent development—from a user‑friendly personal assistant to developer‑focused frameworks, project discovery, and workflow reliability.
