Mantis

Karvi Mantis is a programmable USB HID keystroke injector and an affordable Rubber Ducky alternative developed by Karvi Labs in India. When plugged into a host computer, it enumerates as an ordinary USB keyboard that the operating system immediately trusts. It executes pre-compiled keystroke scripts at machine speed for authorized penetration testing, security auditing, IT administration, and automation.

Yes. Mantis is specifically built as an accessible, high-performance Rubber Ducky alternative in India. Traditional imported keystroke injectors often cost between ₹6,000 and ₹8,500 after international shipping and customs duties. Mantis delivers pre-built, professional USB HID keystroke injection under ₹2,000 with quick domestic delivery across India.

Yes. Mantis provides direct DuckyScript compatibility. You can bring your existing DuckyScript payloads into Karvi Studio, compile them into compact bytecode, and flash them directly onto the Mantis hardware. It also supports the advanced Mantis scripting language with features like functions and hardware button triggers.

Karvi Mantis has a listed price of ₹2,299 MRP with a normal selling price of ₹1,999 (plus an additional ₹200 discount on prepaid orders bringing it to ₹1,799), making it the most cost-effective, pre-built USB keystroke injector and BadUSB alternative available in India under ₹2,000 and ₹2,500.

A BadUSB or USB HID (Human Interface Device) injector is a hardware security device that emulates a trusted input device such as a standard keyboard. Because computers automatically trust keyboard inputs without asking for elevated driver installation, a keystroke injector can type commands and run diagnostic scripts thousands of times faster than human typing.

Mantis is a 100% pre-built, fully assembled hardware device. You do not need to solder pins, assemble enclosures, or write low-level C firmware. It arrives ready to plug in, program with Karvi Studio, and deploy.

You write scripts in Mantis language or DuckyScript using Karvi Studio, our free desktop IDE for Windows. Studio checks your script syntax, provides compiler diagnostics, allows you to step-simulate keystroke execution before running, and uploads the compiled payload to Mantis via USB serial in one click.

No. Mantis uses standard USB HID keyboard descriptors that are universally recognized and trusted by Windows, macOS, Linux, and Android out of the box. No drivers or agent software are ever installed on the target machine.

Yes. The Mantis device is completely legal to purchase, own, and use for authorized security testing, IT automation, education, and research on systems that you own or have explicit written permission to assess. Deploying keystroke injection tools against systems without authorization is illegal.

H1 was the internal engineering codename during prototyping and hardware development. The production shipping product is Karvi Mantis.
