Where each one falls short

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

Attio

  • The free plan stops at 3 seats and 50,000 records
  • Outbound email is capped at 200 messages a month on the free plan and 1,000 on Plus
  • Call Intelligence, sequences, advanced reporting and permission controls all require the Pro tier
  • Custom objects are capped at 3 on free, 5 on Plus and 12 on Pro, with unlimited objects reserved for Enterprise
  • File storage is capped at 50 GB on the free and Plus tiers

Selenium

  • Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
  • Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Selenium: Selenium or Playwright?

Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.

Attio: Are there additional costs for Attio beyond the per-user subscription?

Yes, workspace credits are available as add-ons ($70-$475/month depending on volume). Annual billing provides a 20% discount on the base per-user cost.

Source
Selenium: Is Selenium still relevant?

Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
