OnCrawl provides data in easy to understand graphics. For each aspect of the page Oncrawl will create a graph showing how well pages on your site score. For example, if the titles are consistently too long/short you will quickly be able to see. Likewise, if descriptions are duplicated or headings aren't used to their best potential you will easily be able to tell.
While there is a free all-inclusive 30 day trial, subscriptions start at $19/month ($12.42/month if you sign up for a year-long subscription) which is steep for developing websites. The base plan is limited to 5 websites and 10k URLs per month, but doesn't include any concurrent crawls or custom reports. Prices go up to $279/month ($232.50/month if registered for the year).

While SMB or freelancer plans are available starting at $49/month, the regular plans cost $569, $999, or $2500 per month which is out of reach of most website developers.
While every account is assigned a customer service representative, they are not very helpful. They do not know much about the product and they seem to have alot of turnover in that role. You will not keep the same customer service representative for the duration of your contract as they seem to keep on leaving.
Botify lets you compare what urls googlebot is actually crawling vs the compliant urls you're trying to get indexed. This is an incredibly powerful feature for complex/large websites where you're trying to get longtail content ranked. Using this data you can optimise your sitemaps etc to point google to content it is currently missing.
The data in botify is broken up into current urls, disappeared urls and new urls. This will let you keep track of changes made to your site between crawls.
The botify UI for building reports is very polished and powerful. It supports regex, multiple levels of AND/OR and lets you filter on pretty much any field/data you can think of.
You can set how deep Botify will crawl into your website, as well as how fast and how many URLs. Alternatively, you can set only certain sections of your website to be crawled. Previous crawls can be compared to new crawls to show differences and improvements.
You can easily share reports with co-workers, and set each user to an authorization level (guest/admin/owner) to ensure the right people can make edits, and others can only view the information.
Botify will also crawl through competing sites, allowing you to compare your SEO to theirs, and see where would be most beneficial for you to improve your site's SEO.
