Whisper.Api vs DBOS
Side-by-side comparison of features, pricing, and ratings
Whisper.Api or DBOS: which should you choose?
| Dimension | Whisper.Api | DBOS |
|---|---|---|
| Pricing | Free (self-hosted) | Freemium (open-source core + cloud paid tiers) |
| Primary Function | Self-hosted speech-to-text API | Durable execution for AI agents and workflows |
| Key Feature | Deepgram-compatible, offline, speaker diarization | Postgres-backed state, human-in-the-loop, monitoring dashboard |
| Best For | Developers needing private, offline STT | AI agent engineers wanting fault-tolerant workflows |
| Deployment | Docker, local CPU | Self-hosted or DBOS Cloud |
| Integrations | Deepgram protocol | OpenAI Agents SDK, LlamaIndex, Pydantic AI, Datadog, Prometheus, Grafana |
Choose Whisper.Api if you need a private, offline speech-to-text solution that mirrors Deepgram's API. Choose DBOS if you're building fault-tolerant AI workflows or agents and already use Postgres — it eliminates extra orchestration infrastructure. They solve completely different problems, so your pick depends on whether your need is audio transcription or reliable backend execution.
Self-hosted speech-to-text API that speaks Deepgram's language, built on whisper.cpp so your audio stays on your servers.
