Turning browser automation into an AI Agent

About a year ago, I started trying to build an AI agent to help businesses nurture cold leads (think a hair salon's old clients). My app fell flat when I realized how many of the book solutions didn't support integrations, and those that did often limited the integrations to higher tiers.

Coming back a year later and maybe a little wiser, I decided to take another stab at it, but this time I decided I'd build my own integration. I started using Playwright to create a browser automation that allowed my AI agent to book directly in a business's calendar. No integration required!

We're still testing the waters to see if this is received favorably by business owners. Particularly in platforms where they're locked in without needed integrations.

But I also realize this must be a ripe area for engineers to be building, but honestly I don't see a lot out there yet. Despite the maturity of browser automation tech, why aren't there more AI agents connecting to websites? I think what I've build could be useful to other engineers who want to connect their agents to proprietary systems, but don't want to manage the browser automation themselves.

Am I fooling myself? Is there a good reason why this isn't mainstream?
