If you searched for "agentkit," you may have landed on two very different things. Agentkit (this site, agentkit.ai) is a no-code platform for building AI chatbots and agents that you embed on your website. OpenAI's AgentKit is a separate developer toolkit, announced in late 2025, for engineers building AI agents on the OpenAI API. They share a name, but they solve different problems for different people.
This guide clears up the confusion: what each one is, who it's for, how the pricing works, and what happened to OpenAI's AgentKit in 2026.
The Short Answer
- Agentkit (agentkit.ai) — a hosted, no-code SaaS. You point it at your website, docs, and FAQs, customize a chat widget, and drop it on any site with one line of code. No engineering required. Built for business owners, marketers, and support teams.
- OpenAI's AgentKit — a set of developer building blocks (a visual Agent Builder, the ChatKit UI library, evaluation tools, and connectors) for software teams assembling agentic workflows on the OpenAI API. It requires code, API keys, and usage-based billing.
If you want a chatbot live on your site this afternoon without writing code, you want a platform like Agentkit. If you're an engineer building a custom agent into your own application, OpenAI's developer tooling is aimed at you.
What Is Agentkit (agentkit.ai)?
Agentkit is a no-code AI chatbot platform. The workflow is deliberately simple:
- Add your knowledge. Crawl your website, upload PDFs and documents, add text, or write exact Q&A pairs.
- Customize the experience. Set colors, position, welcome message, and branding to match your site.
- Publish anywhere. Add one script tag to WordPress, Shopify, Webflow, Wix, or any HTML site — or embed via React, an iframe, or the API.
You get a hosted chatbot, a dashboard with conversation analytics, lead capture, domain restrictions, and a choice of models across GPT, Claude, and Gemini. Pricing is a flat monthly subscription with a free tier — see the pricing page and our full chatbot cost guide for the breakdown.
The whole point is that you never touch code or manage infrastructure. For a closer look at how a hosted platform compares to rolling your own with OpenAI's tools, see Custom GPT vs Chatbot Platform.
What Is OpenAI's AgentKit?
OpenAI announced AgentKit at its DevDay event on October 6, 2025. It is not a single product but an umbrella suite of developer tools for building, deploying, and evaluating AI agents on the OpenAI platform. Its main components were:
- Agent Builder — a visual, drag-and-drop canvas for designing multi-step agent workflows.
- ChatKit — an embeddable, customizable chat UI library you wire into your own app.
- Connector Registry — an admin layer for managing how agents connect to data sources and tools.
- Evals for Agents — tooling to grade traces, run datasets, and optimize prompts.
- Guardrails — modular safety checks for agent inputs and outputs.
Even the most "no-code"-feeling piece, Agent Builder, was a developer tool inside the OpenAI API platform: it assumed API keys, token billing, and an engineering team to ship the result. AgentKit is aimed at software developers, not at non-technical business owners who just want a chatbot on a marketing site.
Pricing
OpenAI's AgentKit has no separate subscription. The tools are included with the OpenAI API, and you pay usage-based, per-token costs for the models your agents run, plus metered fees for certain tools. That's a fundamentally different model from a flat-rate SaaS plan: your bill scales with how much your agents are used, and you're responsible for building and hosting the application around it.
What Happened to OpenAI's AgentKit in 2026?
This is where the name gets even more confusing, and it's worth stating precisely rather than overstating it.
OpenAI's AgentKit brand was never renamed. But on June 3, 2026, OpenAI announced the deprecation of two of its central components: Agent Builder and the Evals platform are scheduled to shut down on November 30, 2026. OpenAI is steering developers toward its code-first Agents SDK (Python and TypeScript) as the go-forward path, with ChatKit remaining available for self-hosted chat UIs.
In other words, the more visual, lower-code pieces of OpenAI's AgentKit are being wound down in favor of a code-first SDK. So if someone told you "AgentKit is going away," that's partly right and partly not — the umbrella name is fading and the no-code builder is being retired, but OpenAI's underlying agent tooling continues under the Agents SDK. Either way, it remains a developer framework, not a hosted no-code chatbot service.

Agentkit vs OpenAI AgentKit: Side by Side
| Agentkit (agentkit.ai) | OpenAI's AgentKit | |
|---|---|---|
| What it is | Hosted no-code chatbot platform | Developer toolkit / SDK for building agents |
| Who it's for | Business owners, marketers, support teams | Software engineers |
| Coding required | None | Yes — API keys, SDK, your own app |
| What you get | A live chatbot, embed widget, dashboard, analytics, lead capture | Building blocks on the OpenAI API |
| AI models | GPT, Claude, and Gemini | OpenAI models |
| Deployment | One script tag on any site | You build and host the application |
| Pricing | Flat monthly plans, free tier available | Usage / per-token on the OpenAI API |
| Status (mid-2026) | Active and maintained | Agent Builder & Evals deprecated (shutdown Nov 30, 2026); Agents SDK is the path forward |
Other Tools Named "AgentKit"
The name is genuinely crowded. A few other "AgentKit" projects you might run into — none affiliated with this site or with each other:
- Inngest AgentKit — an open-source TypeScript framework for orchestrating multi-agent networks (
@inngest/agent-kit). - Coinbase AgentKit — an open-source toolkit for giving AI agents on-chain crypto-wallet capabilities (
@coinbase/agentkit). - 0xGasless AgentKit — another, smaller crypto-agent toolkit.
If you're a non-technical user looking to put a chatbot on your website, none of those are what you want either — they're all developer libraries.
"AgentsKit" — the one-letter difference
There is also AgentsKit, at agentskit.co, which is a bundle of specialist agents, skills, and slash commands for Claude Code. The extra "s" is easy to miss and easy to mistype in either direction, so it is worth being explicit: AgentsKit is a developer productivity add-on for a coding assistant, and it is unrelated to this site.
Quick way to tell which one you landed on:
| You want | The product | Who it is for |
|---|---|---|
| A chatbot on your website, trained on your content | Agentkit (agentkit.ai) | Anyone with a website |
| A toolkit for building agents on the OpenAI API | OpenAI AgentKit | Developers |
| Extra agents and commands inside Claude Code | AgentsKit (agentskit.co) | Developers using Claude Code |

Which One Do You Need?
Use this quick test:
- "I want a chatbot answering questions on my website, and I don't write code." → A no-code platform like Agentkit. You can have one trained and live today.
- "I'm an engineer building a custom agent into my own product." → OpenAI's Agents SDK (the successor to AgentKit's builder) or another developer framework.
- "I want agents to manage a crypto wallet." → Coinbase AgentKit.
For most businesses, the honest answer is the first one: you don't need to assemble agent infrastructure from developer primitives. You need a trained, branded chatbot on your site, and a platform handles the hosting, models, and updates for you.
No credit card required.
