Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Countly

  • The private cloud plan starts at $175 a month and is described as usage based without stating the unit
  • No event cap, data point limit or user limit is published for either paid plan
  • The self hosted Enterprise edition is custom priced and billed annually
  • Adaptivity and intelligence features are separately priced add ons on the cheaper plan

Greasemonkey

  • Firefox only. There is no Chrome, Edge or Safari build and there never has been.
  • Its API diverged from the Tampermonkey conventions most shared scripts are written against, so a script from a sharing site may need adjusting to run.
  • The dashboard is plainer than Tampermonkey's, with no diff view when a script updates itself.
  • No cloud sync of the kind Tampermonkey and Violentmonkey offer; moving machines means exporting.
  • A userscript manager can read and rewrite every page you visit, so the security of the arrangement depends entirely on the scripts you choose to install.

Answered from the vendors’ own pages

Countly: What is the difference between Countly Flex and Enterprise plans?

Flex uses usage-based pricing on Countly's cloud with monthly billing. Enterprise requires custom pricing and annual billing, but allows self-hosting on your infrastructure with zero vendor access to data, dedicated support, and included SLA.

Source
Greasemonkey: Does Greasemonkey work on Chrome?

No. It is a Firefox extension and has never shipped for Chrome. Violentmonkey and Tampermonkey are the equivalents there.

Source
Countly: Can I add Adaptivity and Intelligence to Countly Flex?

Yes, Adaptivity and Intelligence suites can be added to Flex as needed. Both are included standard with Enterprise plans.

Source
Greasemonkey: Will Tampermonkey scripts run in Greasemonkey?

Often, but not always. Greasemonkey's API diverged from the conventions most shared scripts are written against, so a script may need its header or its GM calls adjusted.

Source
Greasemonkey: Does Greasemonkey run on mobile?

On Firefox for Android, from version 4.12. There is no iOS build, because Firefox on iOS cannot load extensions of this kind.

Source
Greasemonkey: What is the GM API?

The set of functions a userscript manager exposes to scripts, named after Greasemonkey, which defined it. Greasemonkey supports the promise-based GM. form including GM.xmlHttpRequest and GM.registerMenuCommand.
