This product was not featured by Product Hunt yet. It will not be visible on their landing page and won't be ranked (cannot win product of the day regardless of upvotes).
Every hardware developer has felt the pain of fried microcontrollers, driver setup headaches, and weeks wasted on PCB respins due to a single wrong pin.
We built Kaktus to change that — it’s a browser-native hardware engineering platform where you can design circuits, simulate logic, validate electrical safety rules, and flash code directly to your physical MCU over USB in one seamless window.

Who hunted Kaktus?
Kaktus was hunted by Shubham Dixit. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community. See the full all-time top hunters leaderboard to discover who is shaping the Product Hunt ecosystem.
