When is the Best Time to Launch a Public Beta for My Simple Comments Tool?

Hey everyone! I run a personal blog using a static site generator with Angular, and since I wanted to add commenting functionality, I decided to create my own embedded comments tool tailored for static sites. It's designed to be simple to set up with just a script, and I've been using a proof of concept on my own site so far. I'm looking at the possibility of turning this into a SaaS product but I'm unsure about when to make it public for other developers. I have a few questions: 1) When is the right time to launch a public beta? 2) What are the essential features I need before going live? 3) How can I share it effectively with other developers? 4) Even if I expect things to go smoothly, what should I be cautious about in the early stages? Right now, I have some core features in place, like script-based embedding, IP-based rate limiting, OAuth for multi-tenant authentication, comment moderation, and a single-threaded comment system. My backend setup includes hosting on Render and a PostgreSQL database on the Neon free tier. Any advice or insights, especially from those who've launched developer tools, would be greatly appreciated! Thanks!
