Vapi vs Depot
Side-by-side trajectory, velocity, and editorial themes.
Vapi rounds out transcriber options, real-time signals, and monitoring as its voice infra hardens for production
Vapi's recent releases concentrate on production-grade voice infrastructure rather than new capability surfaces. The transcriber lineup is expanding — Soniox is now GA, Deepgram Flux gained multilingual support, and an autofallback plan lets the platform pick a backup transcriber mid-call if the primary fails. Real-time signals for UI consumers are also maturing: assistant.speechStarted went GA with per-word timing on ElevenLabs and cursor-based word progress on Minimax, opening clean integrations for live captions and karaoke-style UI. Squads agent handoffs picked up a previousAssistantMessages context type, and Monitoring graduated to GA in mid-April with trigger-based rules and dashboard alerts.
The shipping cadence is weekly and the through-line is consolidation from feature-shipping to production-ready surfaces — GA flags, fallback plans, monitoring. The transcriber expansion is the most directional piece: Soniox plus Deepgram Flux plus autofallback selection is both a hedge against single-provider dependence and a clear play for multilingual workloads. The crawler is picking up duplicate stub entries per week alongside the content-bearing ones, which inflates the apparent volume but does not reflect duplicate releases.
Expect a TTS-side mirror of the transcriber autofallback work next, given the symmetry of the voice stack, plus deeper Monitoring integrations — likely structured alert webhooks and custom rule templates. The previousAssistantMessages handoff type suggests more granular context-shaping primitives for Squads are queued.
Depot is rounding out Depot CI into a credible GitHub Actions alternative, and just shipped nested virtualization.
Eight of the last ten changelog entries are Depot CI updates: a new workflow summary page, environment-aware secret and variable variants, CLI commands for metrics, JSON status output, live log streaming, workflow listing and inspection, run cancel/rerun/retry/dispatch, and a DEPOT_JOB_URL env var in every job. Registry got pull-through cache improvements with provider presets. The dominant theme is filling in the feature surface a serious CI platform needs.
Depot is methodically closing the gap between its CI product and the incumbents. The recent run reads like a checklist: workflow UX, secrets, metrics, log streaming, scriptable CLI surface — the table-stakes ergonomics teams expect before migrating off GitHub Actions or CircleCI. The May 20 nested virtualization release expands what kinds of workloads Depot CI can host at all, not just how nicely it hosts them, which is a different and more aggressive move.
Expect more workload-expansion moves following the nested virtualization release — likely Android-specific tooling, deeper matrix/sharding UX (the workflow page already groups matrix failures), and continued CLI parity work. The secrets-and-variables variant model looks set up to grow into broader policy-as-code for CI configuration.
