Where each one falls short

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

Mattermost

  • No prices are published for any of the three paid tiers (Professional, Enterprise, Enterprise Advanced); all require contacting sales
  • Professional is capped at a maximum of 250 users, forcing a move to Enterprise for larger teams
  • Licenses are sold only as prepaid annual subscriptions, and organizations that exceed their licensed seat count must purchase additional seats on a prorated quarterly basis

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
