Amazon confirms Voicebot's analysis: Alexa has over 15K skills, up from 10K in February; Voicebot says Google Home has 378 voice apps and Cortana has 65
Amazon's Alexa voice platform has now passed 15,000 skills — the voice-powered apps that run on devices like the Echo speaker, Echo Dot, newer Echo Show and others.
Context & Ripple Effects
The July 2017 milestone caps a rapid ramp: Amazon reported 7,000-plus skills in January 2017 and 10,000 by February, so the confirmed 15,000 marks a doubling inside roughly six months. Voicebot's same analysis puts the competition far behind — Google Home at 378 voice apps and Cortana at 65 — making catalog size the headline metric of the voice-platform race.
The gap did not hold as a moat: Voicebot counted 25,000 US Alexa skills by December 2017 with growth already slowing, and by early 2019 Google had closed much of the distance with 4,253 Google Assistant Actions, up 2.5X year over year against Amazon's touted 56,750.
First-order effects
- Amazon gets a third-party-validated number to market against Google Home and Cortana, whose catalogs of 378 and 65 voice apps make Alexa the default destination for voice developers right now.
Second-order effects
- Google is forced into a catch-up investment in its Actions platform that shows up two years later as 2.5X annual growth, while Amazon shifts from counting skills to monetizing them, making in-skill purchases generally available in the US by mid-2018.
Third-order effects
- Catalog size proves to be a vanity metric rather than a durable advantage — growth slows after each doubling, pushing both platforms toward surfacing a small set of 'top' skills and paid transactions instead of raw counts.
The trend: Voice platforms are racing from app-count land grabs toward curated, monetized ecosystems as raw skill growth decelerates and Google closes the catalog gap.
