The “pay for it once, own it forever” is appealing. However. I think recent engineering has shown this to be unsustainable. My initial thought was “they don’t plan to update this; no point buying in”.
code rots, Operating systems deprecate libraries that systems depend on. I personally wouldn't' mind paying on a subscription basses to ensure long term viability of a product.
I mean, the core value proposition here is quite good. I've been wanting something like this for awhile. but I'd feel a nervous staking my entire testing flow on a product which has no incentive for ongoing maintenance.
I'll definitely purchase it. I can easily justify it as a business expense and I hope the author of the software finds ways of plugging this product into a larger saas offering so he can continue paying his bills by maintaining this.
