I used Daylite for many, many years, and over many versions, It is indeed a solid, stable product, with lots of useful features - the main one being its unequalled Apple Mail integration, which basically allows you to run your life from inside your Mail app. Other useful features include its free-form database, where you can basically link any piece of information with any other data. Think of linking people to each other, to companies, to emails, to notes, to projects, to quotes, etc. Makes it great for looking at your data from different points of view: click on a client's record to see everything that is relevant to it, on a project to see all related people, etc. These features have ensured it has kept a loyal user-base over the years.
Unfortunately, as the years went on, Daylite did not progress as quickly as the marketplace, and its shortcomings became more and more obvious - specially as they keep on going unaddressed. First and foremost: Daylite is basically a group DATABASE, but any database is only worth the data you can get OUT of it. Reporting is *key* to any successful database platform, and being able to get custom reports on your data is crucial. Daylite reporting is dismal, to say the least. It comes with a 'report editor' where you can, supposedly, create your own report templates. Unfortunately, the process of report creation is not 'drag-and-drop': you need to have a basic grasp of programming, and understand the object-hierarchy that Daylite programmers use, in order to be able to get your data out. Even if you can get the data you want, making it look nice is no easy feat: there will be a LOT of unfriendly tweaking of templates. As with all things Daylite, you can always choose to pay (good money) to one of their 'qualified experts' to create the reports you want...
Then, there is the fact that Daylite was NOT written as a cloud tool, and that trying to integrate it with other tools in your workspace will probably require a myriad of plugins, if at all possible. Want to integrate it with your accounting package? Plugin. Want to get submissions from your website directly into your database? Plugin. Time-tracking? Plugin. Code revision, or ticket management? - sorry, not available, but you can try using the Zapier API.. Or you can always pay a 'qualified expert' to develop it for you!...
Last of all, there is the pricing. Daylite is not targeted at large corporations, but at small-to-medium businesses. For those businesses, $30/user/month is an unrealistic price point. There are many, MANY other online-based solutions that can offer either more specific, or more customisable solutions, for a lot less.
There are general-purpose tools that allow you to easily "build-your-own" solution, for either very little to no cost at all, such as Coda, ZenKit, AirTable or Notion. There are project-management tools that focus on team collaboration and communication, with amazing features and integrations, like ClickUp, SamePage, ProofHub and Monday. We are now spoilt for choice, which makes the case for Daylite very weak.
I give it 2 stars for having fantastic integration with Mail app, and being a well-built, cross-linked database. But I take away 3 stars for the dismal reporting capabilities, lack of true, easy integration with external services, and the ridiculous pricing.
