Antika Circuit: Design, Simulate, and Understand Hardware in the Browser

Antika Circuit is a powerful online platform that lets users design and test electronic circuits directly in their web browser. It removes the need for complex software installations or expensive hardware setups. This tool serves as both a learning environment for students and a professional workspace for engineers who want to prototype quickly and efficiently.

Benefits

Antika Circuit offers several key advantages that make it stand out from traditional design tools. First, it runs smoothly at 60 frames per second directly in the browser, providing a fast and responsive experience without any downloads. Second, it includes a real-time simulation engine that analyzes voltages and currents instantly. Users can change values like resistance or voltage and immediately see the results on an integrated oscilloscope. Third, the platform features an AI-powered tutor that can build circuits from simple text prompts, debug errors automatically, and explain complex concepts in plain language. Finally, it supports real-time collaboration, allowing multiple users to work on the same circuit design simultaneously with shared cursors and live updates.

Use Cases

This tool is perfect for a wide range of users and scenarios. Students can use it to learn electronics basics without needing a physical lab. Teachers can create interactive lessons where students manipulate circuit parameters in real time. Professional engineers can use it for rapid prototyping and validation before moving to physical manufacturing. The platform also supports collaborative design sessions where teams can build circuits together in real time. Additionally, users can transition seamlessly from theoretical schematics to physical breadboard layouts and 3D models, making it ideal for both education and professional hardware development workflows.

Pricing

Antika Circuit offers a free-to-start model. Users can open a browser tab and immediately begin placing components and building circuits without needing to sign up for a credit card or pay upfront fees.

Vibes

The platform is designed to be accessible and welcoming to everyone. The interface avoids intimidating grey CAD tools and instead uses a rounded, calm, and responsive design. Users appreciate that it combines the power of professional simulation engines with the ease of a modern web application. The ability to export designs to industry-standard tools like KiCad and SPICE has been well received by professionals who need to integrate their work into existing workflows.

Additional Information

Antika Circuit is built on a SPICE-lite transient solver based on Modified Nodal Analysis. It ensures that designs are not locked into a proprietary ecosystem by allowing clean exports for ngspice and direct handoff to KiCad. The unified workflow synchronizes across schematic, breadboard, and 3D model views, maintaining a single source of truth for all design changes.
