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.
