Browserless Free Tier No Longer Available: Alternative Required

[DLWCMD]

I am trying to implement the Trip Planner example function. However, it requires a Browserless API key, and the free tier that you cited in your example is no longer available. Further, Browserless may be required for other examples, so we need a free alternative. FYI, the minimum tier charge is now $200 as shown below.

What can you recommend?

Thanks.
