Pro Simple graphics
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.
Pro Checks performance
Performance is checked as well - page load times are tracked and displayed by both speed in seconds, as well as size in kilobytes (or megabytes).
It can crawl up to 250M URLs at 300URLs/sec.
Con Expensive subscription
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).
