1. Your homepage should give me a better sales pitch about what I can do with your product and why I need it, not just how I do it. Explain your value.
2. All content is focused at English audience except the pricing details. Use a dot decimal sign $12.34 not $12,34
3. I would make the connection to your open source project explicit. It’s an asset. Sentry.io does this well
Congrats on shipping!
