The short version

  • Only Google Chrome has a free tier, so it costs nothing to try first.
  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; Google Chrome manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.

Where each one falls short

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

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Google Chrome

  • Manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.
  • The browser is the entry point to Google's account, search and advertising business, and the defaults, prompts and sign-in flows all pull towards a Google account; running it fully detached is possible but requires policy and ongoing attention as new prompts are added.
  • Site isolation runs a process per site, which is correct security design and expensive in memory; on machines with 8 GB and users who keep dozens of tabs open it produces genuine slowdowns and support tickets that no configuration removes.
  • The four-week release cadence means a new major version roughly every month, and even Extended Stable delivers one every eight weeks, so any environment that formally certifies browser versions is permanently behind or permanently re-certifying.
  • Because it ships features first and holds the majority of the market, a team that tests only in Chrome builds against Chrome-specific behaviour and finds out about Safari and Firefox breakage from users rather than from CI.
  • Google has reversed direction on Privacy Sandbox repeatedly, announcing third-party cookie deprecation, delaying it several times and then abandoning it in 2025 before retiring several of the replacement APIs, so any advertising or measurement plan built on Chrome's stated roadmap has had to be rebuilt more than once.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
Google Chrome: Why does uBlock Origin no longer work?

Chrome's Manifest V3 removed the blocking webRequest API that it depends on and replaced it with declarativeNetRequest, which limits how many rules an extension may register. uBlock Origin Lite works within those limits and blocks less. Firefox retains the original API.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
Google Chrome: Is Chrome the same as Chromium?

No. Chrome is Chromium plus Google's proprietary additions: certain media codecs, Google account sync, Safe Browsing integration and usage reporting. Chromium builds omit those, which is why some sites' video playback and sign-in behaviour differ.

Google Chrome: What does enterprise management cost?

Nothing. Chrome Browser Cloud Management, the administrative policy templates and Extended Stable are all free. This is unusual and is a genuine reason organisations standardise on it.

Google Chrome: How often does it update?

A major version every four weeks on the stable channel, with security updates in between, and every eight weeks on the Extended Stable channel intended for managed fleets.

Google Chrome: Is Chrome on iPhone actually Chrome?

No. Apple's platform rules mean it runs on WebKit, so on iOS you get Chrome's interface, sync and account integration on top of Safari's engine, not Blink.
