Stoplight

Stoplight is a web-based platform for API design and management that follows a design-first philosophy. This means you plan and design your API before writing any code, which saves time and reduces errors during development.

The platform includes Stoplight Studio, a visual editor that lets you create API designs using forms instead of code. It supports OpenAPI and JSON Schema standards, which are widely used in the industry. You can work directly with files in your Git repository, making it easy to fit into your existing workflow.

Stoplight automatically generates beautiful documentation from your API designs, creates mock servers for testing, and provides validation tools to catch errors early. It works as a cloud service but also offers desktop and web versions.

Theneo

Theneo is an AI-native documentation platform that transforms how teams create and manage API documentation. Think of it as having an expert technical writer that works instantly - you provide your API specification files (like OpenAPI, Postman collections, or GraphQL schemas), and Theneo generates complete, interactive documentation automatically.

What makes it special is the AI technology that writes descriptions, creates examples, and organizes everything in a clean, professional format. The result looks like high-quality documentation from companies like Stripe or Twilio, but without the months of work typically required.

Beyond just creating docs, Theneo offers developer portals, real-time collaboration tools, automatic changelog generation, and API testing capabilities. It supports custom branding, so your documentation matches your company's look and feel. The platform handles everything from simple internal API docs to complex public developer portals.
