Vapi vs Presto: at a glance
What is Vapi?
Vapi widens its transcriber menu as Soniox hits GA and Deepgram Flux goes multilingual
Vapi is a platform for building voice AI agents. The substantive recent shipping is concentrated in its speech-to-text layer: the Soniox transcriber reached general availability for all customers, and Deepgram's Flux model gained multilingual support — both configurable per assistant. Most other weekly changelog entries in this window are empty placeholders with no described changes.
What is Presto?
PrestoDB ships steady minor releases, but the feed surfaces little beyond version tags.
PrestoDB is shipping sequential minor releases on a regular cadence, reaching 0.298 in June 2026. The changelog feed captures little more than version numbers and links to external release notes, so the substance of each release isn't visible here. Two recent crawl attempts returned error/profile pages instead of release content.

Vapi widens its transcriber menu as Soniox hits GA and Deepgram Flux goes multilingual
◆ Current state
Vapi is a platform for building voice AI agents. The substantive recent shipping is concentrated in its speech-to-text layer: the Soniox transcriber reached general availability for all customers, and Deepgram's Flux model gained multilingual support — both configurable per assistant. Most other weekly changelog entries in this window are empty placeholders with no described changes.
◆ Where it's heading
The visible direction is widening transcriber choice and quality for real-time, multilingual voice agents. Within a short span Vapi promoted one new STT provider to GA (Soniox) and extended multilingual coverage on another (Deepgram Flux), both emphasizing low latency and turn-taking — the parts of a voice agent users feel most. The thin, content-free weekly entries make the rest of the roadmap hard to read from the changelog alone.
◆ Prediction
Expect continued expansion of the transcriber/provider menu and multilingual coverage; beyond the speech-to-text layer the changelog is too sparse to call a confident next move.

PrestoDB ships steady minor releases, but the feed surfaces little beyond version tags.
◆ Current state
PrestoDB is shipping sequential minor releases on a regular cadence, reaching 0.298 in June 2026. The changelog feed captures little more than version numbers and links to external release notes, so the substance of each release isn't visible here. Two recent crawl attempts returned error/profile pages instead of release content.
◆ Where it's heading
The pattern is steady maintenance: numbered releases every one to two months with no directional shifts visible in the feed itself. Crawl reliability is the more actionable signal here — error-page captures mean the feed is degrading, not the product. Readers needing release substance still have to follow through to prestodb.io.
◆ Prediction
Expect the next sequential minor release (0.299) on a similar cadence; nothing in these entries points to a larger version jump or a directional change.
