farmer is an npm package that intercepts tool-call permission requests from AI coding agents and routes them to a mobile-friendly dashboard. Instead of watching a terminal scroll as Claude Code or another agent quietly runs shell commands, you get a swipe-card view on your phone where each pending tool call shows the command, its arguments, and the agent's reasoning — and you approve or deny with a swipe. The architecture is deliberately simple: farmer acts as a hook in the agent's tool-call loop, holds execution until you respond, then forwards your decision back. It ships with a Claude Code adapter out of the box and a documented adapter interface for other agents. The mobile UI is a PWA, so there's nothing to install — just navigate to the local server address in Safari or Chrome. For developers running long agentic sessions — overnight refactors, automated test generation, or repo-wide migrations — farmer fills a real gap. Current tools either block the terminal or run with blind trust. farmer offers a middle path: human-in-the-loop control without requiring you to be physically at your machine.

OpenAI Realtime API WebRTC
Sub-300ms voice AI in the browser, no server relay required

OpenAI's Realtime API now supports WebRTC as a production transport layer, enabling sub-300ms voice-to-voice latency directly in browser and mobile apps without requiring a server-side relay. The release adds server-side VAD (Voice Activity Detection) controls and token-level usage billing for audio streams. This removes the WebSocket relay bottleneck that previously forced developers to route audio through their own backend infrastructure.
Reviewer scorecard
“This solves the exact anxiety of kicking off a Claude Code session and then walking away. The swipe-card mobile UI is well thought out — you can do a quick code review of the pending command right from the notification. The adapter interface is clean enough that I could wire it to my own agents in an afternoon.”
“The primitive here is clean: WebRTC peer connection directly to OpenAI's edge, which means browser-native ICE negotiation handles NAT traversal and the audio path skips your server entirely. The DX bet they made — offload transport complexity to the browser's WebRTC stack instead of making developers manage WebSocket keepalives and audio buffering — is exactly the right call. First 10 minutes is legitimately just grabbing a session token from your backend and calling the peer connection API; the VAD controls mean you're not building your own endpointing logic either. The specific technical decision that earns the ship: billing at the token level on audio streams instead of per-minute flat rates means you're not getting charged for silence, which is the kind of thing that matters the moment you build anything with real pauses in conversation.”
“The security model is concerning: you're routing tool-call details through a local WebSocket server that's exposed to your network. Anyone on the same WiFi can potentially see (or intercept) pending commands. There's no auth on the dashboard in v0.1. Fix that before using this on anything sensitive.”
“Direct competitors here are Deepgram + ElevenLabs in a pipeline, Hume AI's empathic voice interface, and Groq's low-latency audio stack — all of which require more integration work. The scenario where this breaks is multi-tenant applications where you need per-user audio isolation and compliance logging: WebRTC direct-to-OpenAI means your audio never touches your server, which is a privacy feature until your enterprise customer asks for a SOC2 audit trail of every utterance and you realize you've built yourself into a corner. What kills this in 12 months isn't competition — it's OpenAI's own pricing volatility; audio token costs have moved twice in 18 months and any product with margins built around current rates is one pricing page update away from a rebuild. That said, for the majority of voice-in-browser use cases, nothing ships faster right now, so ship.”
“Human-in-the-loop approval is going to become a compliance requirement for agentic AI in enterprise settings. farmer is ahead of the curve — the patterns it's establishing for mobile-first agent oversight will likely influence how official agent SDKs handle permission gating.”
“The thesis this bets on: within 2 years, voice becomes the default interface for a class of ambient computing applications — in-browser, in-app, on device — and the architectural bottleneck isn't model quality but transport latency and server cost. Removing the relay tier collapses infrastructure costs by ~30-40% for high-volume voice apps and enables deployment in contexts where standing up a relay server is a blocker (edge deployments, client-side-only apps, WebAssembly contexts). The second-order effect that matters: this shifts power from infrastructure middleware vendors who built businesses on being the relay layer — companies like Daily.co and LiveKit as voice-AI relay brokers — to application developers who can now go direct. The trend line is WebRTC adoption in AI interfaces, and OpenAI is on-time, not early; Twilio and others have been here for calls, but nobody owned the AI voice path specifically. The future state where this is infrastructure: every SaaS product has a voice command surface that costs pennies per session to run.”
“I run AI agents to manage my content pipeline and frequently can't be at my desk. The idea of approving file writes and API calls from my phone while I'm at a coffee shop is exactly what I've wanted. The activity feed is a nice touch for auditing what ran while I was away.”
“The buyer is any developer building voice-first applications, but the budget question is complicated: audio token costs at scale are brutal, and there's no pricing tier that rewards high-volume committed usage the way AWS Reserved Instances do. The moat analysis is the core problem — this is OpenAI's own API, which means the 'product' for any startup building on top of it has exactly zero defensibility against OpenAI shipping a higher-level voice product that obsoletes your integration entirely; the relay-less architecture actually makes that MORE likely because OpenAI now owns the full audio session and can see every interaction. What happens when a platform player ships 80% of this for free? It already happened — this IS the platform player, and anything you build on it is a feature, not a business. I'd ship if you're using this as infrastructure inside a product with a different moat, but as a standalone voice-AI product, you're building on a foundation that can be pulled at any time.”
