24 alternatives to Workflow builder for realtime voice agents
Hi HN - we’ve been working on a new UX for building realtime voice agents with minimal code. We’ve built a ton of voice agents in the past few years. We noticed that voice agent dev follows a pretty typical pattern: ⁃ Start with a “single prompt” version that dumps all relevant context and instructions into a one prompt, and provide access to all necessary tools the agent will ever need ⁃ As the agent gets more complex and users discover more edge cases, break the single-prompt version out into a more complex structure that gives a user more control over the precise conversational flow.…
A platform for building realtime voice agents with minimal code, VoiceKit streamlines the development process from simple single-prompt versions to complex conversational systems. Designed for developers creating… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Voicebun▲189Hey HN, I built Voicebun as a pet project because I was frustrated with how locked-down and rigid voice agents still are—many tools are either closed platforms, lack deep customization, or charge a lot just to test ideas.

You can: - Clone voices and generate audio using your own scripts and prompts - Dynamically change prompts based on user input - Add custom logic through functions and webhooks (e.g. hit an API,…

I've been obsessed for the past ~year with the possibilities of talking to LLMs. I built a bunch of one-off prototypes, shared code on X, started a Meetup group in SF, and co-hosted a big hackathon. It turns out that there are a few low-level problems that everybody building conversational/real-time AI needs to solve on the way to building/shipping something that works well: low-latency media transport, echo cancellation, voice activity detection, phrase endpointing, pipelining data between models/services, handling voice interruptions, swapping out different…
