Inconsistent tab size (2 / 4 spaces). Easy fix, run through Rubocop.
Might be an idea to have a GH pages site that better markets the tool towards non techies? README seems to try and bundle together marketing lingo with technical details.
Also an example app running somewhere perhaps, that resets every night or something?
We have a similar thing to your DynamicRouter in Caring.com and I would not recommend it! Your use case might be significantly different enough to justify it, but metaprogramming with routes makes debugging a nightmare, if you can, make them namespaced, even if its just /p/:page_slug so you can have regular route helpers, and you don't need to redeclare your routes every time a page is edited.
I probably wouldn't have things like postgres (unless you're using PG exclusive features), unicorn, rollbar, and newrelic in as hard dependencies; we love them but other users of trado have workflows they already use. Maybe make trado a rails engine that is designed to be mounted at the root of another rails app, and offer an example one in the repo.
ApplicationHelper is a little longer than I'd like but the few methods I checked are indeed being used outside of a more specific scope than Application.
Honestly I'm really nitpicking here, this thing looks great. Kept tight to generally considered good conventions, thorough test suite, my only significant comments are more from a marketing perspective than an engineer! I think you need to put an intended-user-hat on (wether that be a web developer or their boss) and work out what would make them want to use this, in the case of the boss, and what would make them know how to use this in the case of the dev. IMO the readme should purely be "quick setup" starting with not even having the repo cloned through to the site running. The website should market the features of your product, and neither of them really should bother delving into your gemfile choices.
As always all of the above is my opinion and not necessarily the right answer! Good luck with this project, it looks awesome :)
