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

FireMonkey

  • Firefox only, and requires a recent one: version 93 on desktop, 113 on Android.
  • Not a drop-in replacement for Greasemonkey, Tampermonkey or Stylus. The project says so itself, so an existing library may need adjusting.
  • A much smaller user base than Tampermonkey or Violentmonkey, which means fewer people have hit the bug you are about to hit.
  • No Chrome, Edge or Safari build, so it cannot be the answer for anyone working across browsers.
  • Combining scripts and styles in one extension also combines the blast radius: one extension with permission to inject both into every page.

Answered from the vendors’ own pages

Countly: How much does Countly cost?

Countly's Flex plan (private cloud) starts at $175/month with pay-as-you-go cancellation. Enterprise (self-hosted) requires custom pricing and annual billing. Both plans include advanced analytics, and Flex offers a 14-day free trial.

FireMonkey: What makes FireMonkey different from Violentmonkey?

It manages user styles as well as user scripts. The usual arrangement is a script manager plus a separate style manager such as Stylus; FireMonkey replaces both with one extension.

FireMonkey: Which browsers does FireMonkey support?

Firefox only. Desktop requires Firefox 93 or later and Android requires 113, with an API minimum of 102.

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
FireMonkey: Is FireMonkey open source?

Yes, under the MPL-2.0 licence.

Source
FireMonkey: Will my existing Tampermonkey scripts work?

Not necessarily. The project states that while it shares functionality with Greasemonkey, Tampermonkey and Stylus, there are differences, so scripts and styles written for those may need adjusting.

Source
FireMonkey: What editor does FireMonkey use?

Current versions use the Monaco editor with ESLint, the same editor component that powers VS Code.
