Scalar API Documentation Platform

An open-source API tooling platform founded in 2023 by CEO Marc Laventure under the MIT license, providing a unified workflow for creating API documentation, generating type-safe SDKs, building API clients, and exposing API capabilities to AI agents through Model Context Protocol servers. The documentation module renders Markdown and MDX content alongside OpenAPI and AsyncAPI specifications, with two-way Git synchronization that keeps documentation in sync with code repositories as the API evolves. The SDK generation system accepts an OpenAPI document and produces type-safe client libraries for TypeScript, Python, Golang, PHP, Java, and Ruby with automatic code sample generation, authentication handling, file streaming support, and synchronization with the documentation portal. The API Client is a fully open-source, offline-first desktop application for Linux, Windows, and macOS that serves as a Postman alternative, built entirely on the OpenAPI standard with local data storage, team collaboration sync, and no vendor lock-in. An API Registry provides centralized management and versioning of OpenAPI documents with deep Git integration for governance. The platform maintains SOC 2 compliance and GDPR certification, with community engagement through Discord and GitHub where the open-source repositories are actively developed. Customer testimonials include engineers from Microsoft ASP.NET praising the modern UI and built-in test code generation across multiple language targets.
