Stainless automates SDK generation for APIs in languages like Python, TypeScript, Kotlin, Go, and Java. Instead of relying on in-house developers to create libraries in multiple languages for its API, Stainless leverages a proprietary system that takes an API specification and generates SDKs in multiple programming languages, utilizing GenAI in the process. This reduces the need for extensive manual coding and documentation.
Stainless can also generate an initial configuration that teams can customize to fit their needs, preventing inconsistencies or outdated libraries while enabling quicker updates and faster integration.
As of December 2024, the company generated annual recurring revenue of ~USD 1 million and was nearing profitability.
Key customers and partnerships
As of December 2024, the company was said to have “hundreds” of paying customers, with its SDKs being downloaded tens of millions of times every week. Notable customers included Meta, OpenAI, and Anthropic.
