The top most-reviewed Salesforce AppExchange apps in 2026 are Docusign eSignature for Salesforce: The trusted eSignature solution, Adobe Acrobat Sign eSignatures for Salesforce, Cirrus Insight for Gmail, 360 SMS App for Salesforce Messaging - Send SMS | WhatsApp from Salesforce | CTI, and SMS Magic & Conversive | Conversational Messaging. These 50 apps have accumulated the most user reviews on the Salesforce AppExchange marketplace, regardless of star rating. Review count is the primary axis for established marketplace presence — apps with 10K+ reviews represent years of cumulative user adoption and are usually the de-facto standard in their category. AppRanks pulls review counts daily; ranking shifts within this list reflect real review velocity changes, not just a rating bump. For new merchants choosing an app, "most-reviewed" answers a different question than "highest-rated" — it surfaces what other merchants ARE using, not just what scores well in isolation. Review count is monotonically increasing for active apps, so position changes here mostly reflect new entrants overtaking incumbents rather than the leader losing reviews — a useful signal for spotting category-defining apps that have crossed the adoption threshold.
