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.

Who should pick which

  • Developer needing offline speech-to-text
    Pick: Whisper.Api

    Whisper.Api provides a drop-in Deepgram-compatible API that runs entirely on local hardware, ensuring no audio data leaves the server. It's perfect for sensitive environments or air-gapped setups.

  • AI agent engineer building fault-tolerant workflows
    Pick: DBOS

    DBOS offers durable execution with Postgres, automatic failure recovery, and native integrations with OpenAI Agents SDK and LlamaIndex. It simplifies building reliable multi-step agents.

  • Team migrating from Deepgram to on-prem
    Pick: Whisper.Api

    Whisper.Api's Deepgram-compatible REST and WebSocket API allows a seamless transition with minimal code changes, while keeping transcription local and avoiding cloud costs.

  • Backend team using Postgres wanting durable queues
    Pick: DBOS

    DBOS co-locates workflow state in Postgres, eliminating the need for separate queue infrastructure. It's ideal for teams that already rely on Postgres and want simple, robust orchestration.

  • Hobbyist with limited hardware wanting STT
    Pick: Whisper.Api

    Whisper.Api runs on CPU-only machines via Docker and supports multiple GGML models, making it accessible even without a GPU. It's free and easy to set up for personal projects.
