About Stainless
By Toolradar Team·
Stainless provides tools to enhance API developer experience by generating robust, idiomatic SDKs and dynamic, synchronized documentation. It automates the creation of production-ready SDKs in multiple languages, handling boilerplate tasks like HTTP requests, retries, streaming, and pagination, allowing developers to focus on building. The SDKs are designed to feel hand-crafted, offering rich types and auto-pagination.
Beyond SDKs, Stainless offers a Docs Platform for creating dynamic API documentation that stays in sync with the actual API. This platform supports REST API, SDK, and narrative documentation within a single codebase, built on Astro for extensibility and deployability. It's designed for API providers who want to improve adoption, reduce support overhead, and enable integrators to ship products faster with high-quality developer resources.

Stainless FAQ
How does Stainless ensure the generated SDKs are 'idiomatic' across different programming languages?
Stainless SDKs are designed by a team with decades of experience at major API companies, focusing on language-specific conventions and best practices. This ensures that while the SDKs are auto-generated, they incorporate rich types, auto-pagination, and retry mechanisms that are natural to each language, making them feel as if they were hand-written by an expert in that specific language.
Can the Stainless Docs Platform integrate with existing content management systems or require a specific setup?
The Stainless Docs Platform is built on Astro and allows for content authoring in Markdown, MDX, or Markdoc. It is designed to be maintained as code in a GitHub repository, offering flexibility. While it doesn't explicitly detail direct integrations with external CMS, its foundation on Astro and support for custom components means it can be highly customized to fit various content workflows and deployment environments.
What level of customization is available for the generated documentation sites?
Documentation sites generated by Stainless are built with Astro, an open-source framework. This provides extensive customization options, from modifying individual components to completely altering the UI. Users can define custom content components in React or as Astro components, allowing for a unique look and feel that aligns with their brand.
How does Stainless handle API changes to ensure SDKs and documentation remain synchronized?
If you use Stainless SDKs, the platform automatically updates your documentation and code snippets to reflect the latest API changes based on your OpenAPI specification. This ensures that any modifications to your API are consistently propagated across both your SDKs and your developer documentation, maintaining accuracy and reducing manual effort.
What is the scope of the 'AI-powered hybrid search' feature within the Docs Platform?
The AI-powered hybrid search in the Stainless Docs Platform is designed to help developers quickly find relevant information within the documentation. While specific details on its implementation are not provided, hybrid search typically combines keyword-based search with semantic understanding to deliver more accurate and contextually relevant results, improving the overall discoverability of API information.
Are there any plans to support additional programming languages for SDK generation beyond the currently listed ones?
Stainless currently supports TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, C#, and Terraform, with Rust in early access and Swift coming soon. The platform is continuously evolving, and new languages are added based on demand and strategic development, indicating a commitment to expanding its language support.
