As answered by people managing Frset and Cert Decoder.
Frset's answer
Frset started from a simple frustration: using a Mac often means installing many small apps for tasks such as clipboard history, screenshots, OCR, translation, notes, system monitoring, and developer utilities. Each tool may be useful on its own, but switching between them adds friction and can quickly clutter the menu bar. Frset was created to bring these frequently used workflows together in a lightweight, native Mac app while keeping each tool focused and easy to use.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Frset's answer
Frset is designed for Mac users who frequently work with text, screenshots, copied content, images, and small productivity utilities throughout the day. Its primary audience includes developers, designers, product managers, writers, creators, students, and other knowledge workers who want faster access to common tools without constantly switching between apps.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Frset's answer
Frset is a good fit for people who would otherwise install several separate Mac utilities for clipboard history, screenshots, OCR, translation, AI actions, and developer tools. Instead of focusing on only one of these workflows, Frset keeps frequently used tools together with a consistent native macOS experience. It also offers a useful free version, with an optional one-time upgrade for users who need more.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Frset's answer
Frset brings many everyday macOS productivity tools into one native app without trying to turn them into a complicated all-in-one workspace. It combines clipboard management, screenshots, OCR, translation, AI shortcuts, Markdown notes, developer utilities, system monitoring, and calendar tools while keeping the experience lightweight and easy to access. Frset is also local-first, so most everyday data and workflows stay on your Mac.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
