Hi Product Hunt! I’m Otto, the developer behind CodeSwissKnife. I first built CodeSwissKnife because I was tired of searching for small developer utilities every time I needed to format JSON, decode a JWT, inspect a certificate, compare data, or convert something quickly. The bigger issue was privacy. These tools are often used with API payloads, tokens, logs, certificates, and internal project data, and I didn’t want to keep pasting that into random websites. I’d really appreciate your feedback, especially on this question: What developer task do you still solve with a random website because you haven’t found a good local tool for it yet?
