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.

Apidog

Apidog is a platform that handles the complete process of creating and managing APIs. You can design your API structure, test how it works, create clear documentation, and share it with your team, all from one application.

The platform follows a design-first approach, which means you plan your API before writing code. This helps catch problems early and keeps everyone on the same page. It automatically creates mock servers so front-end developers can start working before the back-end is ready.

There is a free version that works great for small teams and individual developers. Paid plans add more features like unlimited projects, advanced testing tools, and priority support for growing businesses.
