{"API Design"}

These are the companies, and organizations who are doing interesting things with design of APIs. If they have an API, I'm working to profile, and provide machine readable indexes of each one below.

API Stylebook
A Github hosted, aggregate set of API design topics. The API Stylebook has brought together the API design style guides of leading API providers and merged them into a single source of API design principles. It is hosted on Github, with the data behind available as YAML, making it easily forkable, and replicable for any API provider looking to establish their own API design guide.
Apiary
Apiary jump-started the modern API design movement, by making API definitions more than just about API documentation, allowing API designers to define APIs in the machine readable API definition format API blueprint, then mock, share, and publish documentation via a cloud platform.
Apigee API Studio
Apigee launched their API Studio out of their earlier Apigee-127 product, their work on the Swagger platform and editor, and their BaaS offering, opening up the ability for developers to design, mock, test and share via the online platform. While Apigee Studio is part of the larger Apigee line of products, it is a separate standalone, open source based studio.
APIMATIC
When you use APIMATIC to manage SDKs, they provide you with an editor for adding, editing, and deleting the details of each API. When you bundles this with their multi-format API definition format import and export, the platform quickly becomes an API design tool as well as a platform for generating your SDKs.
Apimint
APIMINT is an API lifecycle management tool. With our design first approach, all stake holders get a platform to collaborate and give feedback on API design and structure. We make sure your all your teams can easily agree and understand your APIs.
Gelato.io
Gelato.io is a tool focused on creating API Documentation and Developer Portals. You can describe your API, import and sync with Swagger or API Blueprint, have your developers register and get updates when things change, get an automatic API Explorer.
Goa
goa provides a novel approach for developing microservices that saves time when working on independent services and helps with keeping the overall system consistent.u0026nbsp;
Mashape
Mashape provides an API editor, as part of their API management and discovery platform, allowing API providers to add, edit, and manage the details of an API design, while also managing the rest of API operations--from design to discovery and integration. Mashape editor is just a piece of the overall Mashape suite of API lifecycle management tooling.
Materia
A modern development environment to build advanced mobile and web applications. Materia is an easy-to-use backend to build all kinds of applications (mobile, web, gaming and more). Materia tooling aims to manage the entire development cycle for building enterprise class backends.
MuleSoft
Mulesoft provides a cloud, and open source version of their API design editor, enabling API designers to craft APIs using the RAML API definition format, then publish to notebook, as well as manage through other aspects of the API lifecycle with other Mulesoft systems.
RepreZen API Studio
RepreZens solution focuses specifically on the API design process in large organizations and complex ecosystems. API management platforms address various aspects of the downstream lifecycle: packaging, provisioning, metering, proxy, and client portal. API Studio easily ties into API management platforms using generated API description formats including WADL, Swagger, RAML and others.
Restlet
The Restlet API Platform enables developers and non-developers to design, create, run and manage the APIs that provide access to any data or application. Restlet Framework is the most widely used open source solution for Java developers who want to create and use APIs. The first Platform-as-a-Service dedicated to web APIs, APISpark enables any organization to become an API provider in minutes via an intuitive browser interface.
Visual Paradigm
u0026nbsp;Visual Paradigm supports modeling the underlying communication model of REST API, as well as the generation of REST APIs and API documents.
