Claude Code Local turns your MacBook into a fully self-contained Claude Code environment, replacing the Anthropic API backend with locally-running models on Apple Silicon. Choose from Qwen 3.5 122B (65 tok/s), Llama 3.3 70B (7 tok/s), or Gemma 4 31B (15 tok/s) — all running via the MLX framework on your GPU, no internet required. Four operating modes are included: standard IDE coding, browser automation agent, hands-free voice with voice cloning, and an iMessage pipeline integration. The privacy commitment is absolute — zero outbound network calls from the project's own code. The only exception is a one-time startup handshake to verify Claude Code's binary. Purpose-built for NDA environments, legal workflows, and healthcare use cases where sending code to a cloud API is a non-starter. With 2,300+ stars and 453 forks, Claude Code Local is quietly becoming the go-to for privacy-conscious developers. Version 2 fixed critical tool-call formatting bugs that caused infinite loops in local models, and a 98/98 test suite pass rate suggests production readiness.

Tether — yes, the stablecoin company — has launched QVAC, a fully open-source SDK for building on-device AI agents that work offline, peer-to-peer, and without any dependency on centralized cloud infrastructure. Built on a customized fork of llama.cpp called QVAC Fabric, it supports text completion, embeddings, vision, OCR, speech-to-text, text-to-speech, and translation — all running locally on Linux, macOS, Windows, Android, and iOS with a single unified API. What makes QVAC architecturally distinct is the Holepunch protocol stack underneath it: models can be distributed peer-to-peer, inference can be delegated across devices without centralized infrastructure, and the roadmap includes decentralized swarms for training and fine-tuning. Once a model is cached locally, the SDK works fully offline — making it suitable for air-gapped deployments, field work, and restricted-network environments. Tether is also running a developer grants program to fund projects building with QVAC, specifically targeting local-first AI and payment applications. With $27B+ in stablecoin reserves behind it, Tether has the runway to sustain a multi-year open-source effort here — which is more than most AI SDK projects can say.
Reviewer scorecard
“65 tok/s Qwen locally is actually usable for real coding — the v2 fixes to tool-call formatting make a huge difference. For NDA client work where I can't send code to Anthropic, this has become essential. The MLX optimization is genuinely impressive engineering.”
“A single API covering text, vision, speech, OCR, and translation — locally, cross-platform, offline — built on llama.cpp with P2P model distribution via Holepunch. This is the toolkit for building genuinely private AI apps, especially on mobile where on-device inference is finally practical.”
“Local models still lag behind Claude 3.5 Sonnet significantly on complex coding tasks. You're trading quality for privacy and cost savings — a reasonable trade for some, but a painful one for gnarly refactoring jobs. The gap is real and matters.”
“Tether's business is stablecoins, and grafting a major open-source AI SDK onto that brand is an unusual strategic move that raises questions about long-term commitment. The Holepunch P2P stack is powerful but adds significant complexity — most developers just want a simple local inference wrapper, not a decentralized agent protocol.”
“When you can run a 122B model at 65 tok/s on a laptop, the question of 'cloud vs local' becomes a policy choice, not a capability choice. This project shows that frontier AI is commoditizing faster than most vendors want to admit.”
“QVAC represents the counter-narrative to cloud AI monopolization: intelligence that lives on devices, syncs peer-to-peer, and never phones home. Combined with Tether's payment rails, this could be the foundation for AI agents that transact autonomously in a fully decentralized stack.”
“The hands-free voice mode with voice cloning is the sleeper feature — coding by talking to your Mac is surreal and surprisingly productive. For accessibility-focused builders and creative technologists, this opens doors that cloud API pricing keeps shut.”
“Local speech-to-text, translation, and OCR with one SDK, working offline on my phone? The creative use cases — offline transcription in the field, private on-device captioning, local image analysis — are immediately compelling without needing to trust a cloud provider with my content.”
