About TullyAPI

TullyAPI is a privacy-first, browser-based API testing tool that enables developers to test HTTP APIs without compromising data security. Unlike traditional API testing solutions, TullyAPI stores all data locally in the user's browser, ensuring that sensitive information like API keys, request data, and responses never leave the device.

Launched in November 2025, TullyAPI provides a lightweight alternative to desktop-based API testing tools, requiring no installation or account creation. The tool is completely free with no premium tiers or limitations, making professional API testing accessible to all developers.
