Introducing Union Station: our web app performance monitoring service

You point out the recommended plan - which jumps out - but it's very difficult to easily compare the plans. My two cents: use graphics (checks or bullets) for included features, leave out features that are the same across the board (like no setup fee), and reduce it to critical features only.

The rest of the site looks great, I love the design/UI.

I understand they acknowledge this, but I'd be as unlikely to use a product like this as I'd be to use a remote memory profiler. Which is pretty unlikely.

I can't quite tell from the launch page what level of detail is conveyed, but if you can tell what gems, method names and data sources are used that could be a competitive advantage. There are plenty of profiling and targeting applications/services that people are unlikely to want to reveal that they're using. I'd also be concerned about the increased visibility an attacker might be able to gain into a public application.

I saw that a "firewall" edition is in the works, and I understand the appeal of ongoing fees with SAAS, but I'm still surprised people are willing to remote out code insight to this level. At least, I haven't seen offers of hosted debuggers, profilers, compilers etc. Has gmail and basecamp really softened up the market that much?
