As the landscape of developer tools rapidly evolves, API documentation platforms are adapting to meet modern needs, prompting a reevaluation of GitBook alternatives for 2025. The guide explores several platforms—Mintlify, Stoplight, Postman, Redocly, API Hub, and Readme—analyzing their features based on user experience, developer workflows, collaboration, maintenance, AI readiness, and pricing. Each platform offers unique strengths tailored to different team needs, such as Mintlify's AI-native features and developer focus, Stoplight's emphasis on OpenAPI-driven development, and Postman's synchronization with API implementation. The exploration underscores the importance of aligning documentation tools with team-specific workflows and technical requirements, as AI becomes increasingly central in how developers interact with product documentation, ensuring these tools match the evolving expectations and efficiencies required by modern developers.
