Header Forge · Request Headers

Customize request headers with URL wildcards, drag-to-reorder, single-rule sharing, and individual toggles.

Header Forge helps developers and testers add custom HTTP/HTTPS request headers without changing application code. Use it to test authentication, switch environments, and debug API requests with precise URL wildcard rules. Enable headers individually, drag to set their priority, and copy or paste configurations for reuse. Its compact interface and global pause switch make everyday debugging easier to manage. With local configuration storage, no account requirement, and no telemetry, Header Forge gives you a straightforward way to control your request headers.
