Loved by developers & indie builders
Nice build. Local-first + open source is exactly what security tools should aim for.
Honestly, that is such a smart idea. Lately when I'm building, I feel naked with my API keys. Great job, I love it!
Such a smart idea! Protecting secrets before they ever leave your machine just makes sense.
Really cool project and could definitely save some people. I've gotten close with my .env, I hate to admit!
Secret Sanitizer is a brilliant safeguard. Auto-masking secrets locally before they hit AI chats keeps everything secure without the cloud risk. Love the open-source vibe!
This is genuinely useful. The number of times I've had that split-second panic after pasting something into ChatGPT is way too high. Love that it's fully local and open source. No way I'd trust a closed-source tool that scans my clipboard!
This is actually so useful. I've definitely pasted stuff I shouldn't have into AI chats before. Congrats on the launch!
