Describe an agent in plain language — AIQY builds and runs a real, durable AI agent on your own model.

Install · How it works · Security · Built on Eve

AIQY is an open-source, self-hostable studio for building AI agents. You write what the agent should do, pick a few tools, and AIQY generates a real agent, compiles it, and runs it — all on a model you connect (any OpenAI-compatible endpoint, including local Ollama / LM Studio / vLLM). No cloud lock-in, no keys leaving your machine.

Under the hood AIQY builds on Eve, Vercel's open-source agent framework, and reuses its durable runtime, sandbox, and channels — so AIQY focuses on the layer Eve doesn't have: a visual, model-agnostic builder for everyone, not just developers.

Or just talk to Json — a chat-first builder that designs the agent, writes the tool code itself (compiling and self-correcting until it works), and builds it while you describe what you want.

Why AIQY

• Bring your own model. Any OpenAI-compatible endpoint — local or cloud. AIQY runs entirely outside the Vercel AI Gateway (the thing that normally ties Eve to Vercel).
• Real agents, not toy flows. Every agent is a genuine Eve project with durable execution, tools, and a running HTTP endpoint — generated as inspectable files.
• Instant. Dependencies install once; each new agent is just files, created in an instant.
• Self-hosted & private. Runs on your machine. Your model, your keys, your data.
• Open source. MIT licensed. Fork it, extend it, ship it.

Installation

Prerequisites

• Node.js ≥ 24 — download here.
• A model — either a local model via Ollama (free & private) or a cloud API key (OpenAI, Anthropic, Google, Groq, OpenRouter). You can set this up after install.

1. Get the code

git clone https://github.com/JellowBeanz26/aiqy.git
cd aiqy

(Or download the ZIP from the green Code button on GitHub and unzip it.)

2. Install & run

npm install
npm run dev

Open http://localhost:4300. The first run installs a shared Eve runtime once (~30s — one time only).

Pinned & reproducible. AIQY installs Eve and the AI SDK at exact versions (no floating ^ ranges), so upstream releases can never change what your install pulls — you always get the exact set AIQY was tested against. You never install Eve by hand; AIQY does it for you.

3. Connect a model

In Settings, pick one:

• Local — free & private. Install Ollama, then pull a model:

  ollama pull qwen2.5:3b     # small & fast — good on a laptop CPU

  In Settings → Local model → Connect (http://127.0.0.1:11434/v1) → choose the model.
• Cloud — fast & powerful. Settings → Cloud API → paste any key (sk-… OpenAI, sk-ant-… Anthropic, AIza… Google, gsk_… Groq, sk-or-… OpenRouter). AIQY detects the provider and lists its models automatically.

On a CPU-only machine, prefer ~3B–7B local models (or an MoE like qwen3:30b-a3b), or use a cloud key for the biggest models.

4. Build an agent

• Talk to Json — describe what you want in the chat; Json designs it, writes any tools it needs, and builds it.
• Or New agent — write the instructions, pick tools, and hit Build agent.

Then chat with your agent. That's it. 🎉

Json writes real code. When an agent needs a custom tool, Json writes the TypeScript for it — compiling and self-correcting until it passes. This shines with a capable model: a local MoE like qwen3:30b-a3b, or any cloud model. Tiny 3B models are great for running agents but may not reliably write custom tools; if a tool doesn't come out right, Json says so instead of shipping a broken agent.

        └────────────────┘          └──────────────────┘

• Generator (lib/generator.ts) writes a complete Eve agent from a spec. The model is configured via a baked defineAgent({ model: createOpenAICompatible(...), modelContextWindowTokens }) — the modelContextWindowTokens is what lets Eve skip the Vercel model catalog and use any endpoint.
• Validator (lib/validate.ts) runs eve info --json and returns a structured verdict.
• Agent Manager (lib/agent-manager.ts) spawns and supervises one eve dev process per agent and proxies its HTTP API.
• Chat client (lib/eve-client.ts) drives an Eve session (POST create + NDJSON stream).

Generated agents and settings live under .data/ (gitignored).

Tool library

The built-in Eve framework tools (web_fetch, web_search, bash, read_file, write_file, …) are available to every agent for free. AIQY adds a small curated library for the gaps (lib/tool-library.ts): http_request (call any API), get_current_time, and more to come.

Roadmap

• Bring-your-own-model (local + cloud), builder, run/chat, self-correct validation.
• AI-assisted builder — turn a one-liner into instructions + tool selection.
• Studio — a visual run dashboard (session/turn/step waterfall + token/cost).
• More channels (Slack, Telegram, WhatsApp, email) and a one-command Docker deploy.

Security

AIQY is a single-user, self-hosted tool. Its security model:

• Your keys stay local. API keys live only under .data/ (gitignored, never committed) and are injected into agents at runtime via the process environment — they are never written into an agent's source files.
• Generated tool code is real code. Agents (and Json) can generate tools whose execute() runs in the agent's Node process with your user's permissions. Build and run only agents you trust — treat it like running code you wrote.
• Nothing is exposed by default. AIQY listens on localhost and agents run as local processes. If you deploy it beyond your own machine, add authentication and isolate the agent processes (e.g. one container per agent).
