| # | Provider | ScoreScore from 0 to 100 for this channel. Weights: Pricing & Free Tier 30 %, Developer & AI Readiness 30 %, Reputation & Reviews 25 %, Category Functionality 15 %. Computed from the verified facts on each provider card, never set by hand.How it's calculated | CoverageShare of the rating's weight backed by verified facts. Criteria without a verified fact are left out and the remaining weights are scaled up, so a lower number means the score rests on fewer facts.How it's calculated | EvidenceHow strong the sources behind the verified facts are. Strong: mostly the vendor's own documentation. Moderate: more facts from other official pages or third-party sources. Limited: many facts rest on vendor marketing claims.How it's calculated | 1,000 outbound SMS / month (US, official pricing) | Developer |
