Versions:
voice-tunnel is a developer utility published by JuanjoFuchs that enables voice-based communication with coding agents from a phone browser, without requiring any app installation. Currently at version 0.2.7, with eight versions released to date, the software falls into the developer tools and voice interface category, specifically targeting workflows that involve AI-assisted coding agents. Its core purpose is to open a web page that any phone browser can load, establishing a two-way audio channel between the phone and whichever coding agent initiated the session. This design allows developers to talk to their coding agent remotely through a familiar mobile browser interface, making it suitable for use cases such as issuing spoken instructions to an agent while away from the desk, reviewing agent output hands-free, or interacting with a coding assistant from another room or device on the local network. A defining characteristic of voice-tunnel is its local-first architecture: speech recognition, speech synthesis, and the voiceprint processing all run entirely on the user's own machine rather than relying on external cloud services, which supports privacy-conscious workflows and keeps audio data under local control. The software requires no GPU to operate, lowering the hardware barrier for adoption and making it practical on standard development machines. By combining bidirectional audio transport with on-device speech processing, voice-tunnel positions itself as a lightweight bridge between mobile browsers and local coding agents, offering an accessible voice interface for agent-driven development without additional mobile software, specialized hardware, or dependence on third-party voice platforms.
