Why it's listed

Rocket.Chat is listed in team chat & messaging because it competes on utility: feature-rich team chat. It's VC-backed — we note this openly and watch the monetization path; the license and self-host route are the safeguards. Licensed MIT/enterprise; pricing: free (ce) / enterprise. It's on the heavier side for its category — we score that honestly and say so. This entry is provisional — the scores are seeded estimates pending our full manual rubric pass, and the verification date will appear here once complete.
