What is APIPark?

APIPark is an open-source, Apache-2.0 licensed, cloud-native AI gateway and API developer portal that connects to more than 100 AI models and turns them into governed, shareable REST APIs for developer teams and enterprises.

What it is

APIPark is an all-in-one AI gateway and API developer portal written in TypeScript and released under the Apache-2.0 licence, which permits commercial use. It lives in the cloud-native API gateway ecosystem and combines two roles in one deployment: a high-performance traffic gateway that supports cluster deployment and large-scale traffic, and a developer portal where teams publish, subscribe to, and monitor APIs. The project spans the AI gateway and LLM gateway categories as well as the classic API gateway, API portal, developer portal, and apihub categories in this registry.

The concrete problem it solves is model churn and integration sprawl. Applications that call AI vendors directly must be rewritten when the model or prompt changes, and teams that share API keys informally lose track of who calls what. APIPark standardises the data format of all AI API requests so that switching models or editing prompts does not affect the calling application or microservice. It also replaces ad-hoc key sharing with application and key management, subscription review, and approval before an API request is allowed through.

Key capabilities

  • Connects to 100+ AI models, including OpenAI, Azure, Anthropic Claude, Google Gemini, DeepSeek, ByteDance Doubao, ChatGLM, ERNIE Bot, iFlytek Spark, Tongyi Qianwen, 360 Zhinao, and Tencent Hunyuan, behind a unified API request and response format.
  • Combines an AI model with prompt templates into a new REST API, such as a sentiment analysis API, translation API, or data analysis API built on OpenAI GPT-4 plus custom prompts.
  • Provides a developer portal for sharing APIs within a team, and for managing complex AI and API call relationships.
  • Manages calling applications and API keys, with subscription review required before API requests are allowed and granular permission management for application calls.
  • Monitors AI API usage with charts, and exports API request logs to third-party logging platforms.
  • Operates as a cloud-native API gateway with cluster deployment, positioning itself as higher performing than Nginx for large-scale traffic.
  • Supports multi-tenant management with flexible subscription and approval processes for different business units.
  • Installs through a single command: curl -sSO https://download.apipark.com/install/quick-start.sh ; bash quick-start.sh.

Who uses it and how

  • Enterprises integrating AI into internal and third-party APIs, so that AI agents can perform complex tasks beyond knowledge-based question answering.
  • Teams that expect to switch model vendors, using the standardised request format so a model or prompt change never touches the app or microservice.
  • Platform teams building an internal API developer portal, reducing tangled system call relationships and the data breaches caused by chaotic API calls.
  • Compliance- and security-focused organisations needing service governance, granular call permissions, and approval workflows on every subscriber.
  • Multi-tenant organisations where separate business units need isolated management and their own subscription paths.

Getting started

Deploy with the documented one-command quick start: curl -sSO https://download.apipark.com/install/quick-start.sh ; bash quick-start.sh. The README states the gateway and portal are up in under 5 minutes; project homepage is https://apipark.com.

How it compares

Among similar tools named in the facts, Nginx is the direct point of contrast: APIPark is presented as a drop-in gateway layer that outperforms Nginx while adding AI model connectivity, prompt-to-API packaging, and a developer portal that a plain reverse proxy does not provide. Nginx remains the narrower tool, since it handles HTTP proxying without the AI routing, key governance, or subscription approval that APIPark bundles.

When to use it — and when not to

Pick APIPark when the gateway and the API portal are both wanted, and when the team will run the self-hosted service that the quick-start script installs from download.apipark.com. Do not pick it for a plain HTTP reverse proxy, since Nginx is the smaller and better understood option for that job, and do not pick it if policy forbids fetching an installer from a vendor-controlled download domain, because the README documents no alternative install path. The performance claim against Nginx is project-stated rather than independently verified here, the README excerpt is truncated, and 53 open issues and 245 forks indicate an active but still maturing project.

💌 Why Did We Build APIPark?

Before building APIPark, we spent seven years developing an API development and automated testing platform with over 1 million developer users, 500+ enterprise customers, and multi-million-dollar investment from Sequoia Capital.

As AI and Agents evolved, we noticed many enterprises wanted to integrate AI into both internal and third-party APIs, enabling AI agents to perform more complex tasks beyond being just knowledge-based Q&A bots. Hence, we built APIPark—your all-in-one AI gateway and API developer portal to accelerate your AI API development and quickly build your product or AI agent!


✨ Quick Start

APIPark is designed to solve the following problems:
