Congrats on the release, I'm really impressed with OpenPanel so far!
I have also been building a similar product for a long time (UXWizz), focused more on self-hosting, quantitative data and targeted at low to medium trafficked websites, but it is a paid product.
How do you think monetization will pan out in the long-term with a free self-hosted option? I know PostHog also had a free self-hosted version, but since the self-hosted version competes directly with their main business model, they had to stop support for it.
I also considered open-sourcing mine, but decided to keep it self-hosted only and paid. I feel like if I sell a hosted version, then my business goals won't be aligned with the goal of making the self-hosted version as good as it can be, without feature locks.
I hope you can maintain this awesome pace and improve your product for many years to come!
