About

FetchSandbox helps you test the integrations your AI wrote without touching production. From API request to production-ready integration, it lets developers build, test, and validate API integrations in realistic environments before deployment, catching failures early, reducing debugging time, and shipping with confidence. Instead of relying on static mocks, fake success responses, or risky production keys, FetchSandbox gives teams runnable API environments that behave like real services. Its stateful API sandbox keeps state across requests, enforces lifecycle transitions, fires real webhook events, and supports multi-step flows where integrations usually break. Developers can use the MCP Server, CLI, web app, OpenAPI import, and monitoring tools to prove an integration against APIs such as Stripe, Resend, Clerk, GitHub, Paddle, and Shopify.

About

Scalar is a modern, open source API platform designed to help developers create, document, test, and manage APIs through a unified, interactive environment built around the OpenAPI standard. It transforms OpenAPI specifications into clean, visually appealing, and interactive API documentation that allows users to explore endpoints and test requests directly within the interface, combining documentation and a full-featured API client in one place. It includes a built-in REST API client that supports sending requests, inspecting responses, handling authentication methods such as API keys and OAuth2, and working with environment variables and dynamic parameters. Scalar also offers tools for generating SDKs, managing and versioning API specifications with Git integration, and creating documentation that stays synchronized with the underlying API through Markdown or MDX workflows.
