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
Context & Ripple Effects
The skill-count race has been Amazon's to lose all year: the catalog went from 7K skills in January past 10K by February, and Amazon's confirmation of Voicebot's 15K figure makes it official rather than analyst-derived. The more striking number is the gap behind it — Voicebot counts just 378 voice apps on Google Home and 65 for Cortana.
That gap reframes the smart-speaker market as a two-horse developer-ecosystem contest, which is exactly how it plays out over the next two years: Alexa's US catalog reaches 25K by December, while Google Assistant only begins closing the distance when its Actions hit 4,253 in January 2019.
First-order effects
- Voice developers picking a platform now face a ~40x catalog gap between Alexa and Google Home, tilting new skill investment toward Amazon's store by default.
- Google Home and Cortana are publicly cast as distant also-rans in third-party voice apps, pressuring both to court developers harder.
Second-order effects
- Amazon converts its catalog lead into a monetization layer, generalizing in-skill purchases as the skill base scales from 25K to 40K through 2018.
- Google's forced response arrives as a catch-up sprint: Actions grow 2.5x year-over-year into early 2019, still trailing an Alexa catalog of 56,750 US skills.
Third-order effects
- If raw catalog counts keep deciding perceived leadership, voice assistants consolidate around one dominant third-party app economy — with discovery and quality, not quantity, becoming the next battleground once growth slows.
The trend: Voice assistants are competing less on hardware than on who hosts the largest third-party skill economy, with Amazon's head start compounding against Google and Microsoft.
