What are the limitations of Modyak?

macOS only, so Windows and Linux developers cannot use it. Covers a narrow job: model routing for a few agents, not a broader AI workflow tool. Output quality depends on the chosen model, which may not match Claude on agentic tasks.

What is Modyak?

Modyak is a free macOS menu-bar app that lets Claude Code, Claude Desktop, Codex CLI and Codex Desktop run on other models such as DeepSeek, Kimi, Qwen or local Ollama, using one-click presets instead of manual config files.

Modyak is a small macOS menu-bar app built for developers who use coding agents but do not want to be tied to a single model vendor. It sits in the menu bar and redirects Claude Code, Claude Desktop, Codex CLI and the Codex Desktop app to a different backend model, so the agent interface stays the same while the model underneath changes. The workflow is built around presets. A preset is a named combination of providers and models, and switching between them takes one click in the menu. The homepage shows examples such as a sustainability-focused option using NeuralWatt and GreenPT, a fully EU-hosted option using Anthropic via Eurouter, a cost-versus-performance option pairing DeepSeek-V4-Pro with Kimi 2.6, a local option using Ollama with no cloud involved, and a bring-your-own option for providers like OpenRouter and Groq. The app runs on a random local port, and a terminal session launched afterwards reports that it is running via Modyak with the chosen model, which suggests the routing happens through a local endpoint rather than by editing each tool by hand. The practical appeal is that it removes manual configuration. Normally, pointing an agent at a different model means editing config files or environment variables and keeping them in sync across tools. Modyak handles that step for the user. The listed providers include Anthropic, OpenAI, GreenPT, Eurouter, NeuralWatt, NVIDIA Build, Hugging Face, Groq and Fireworks, plus local Ollama, and a knowledge base documents provider setup. Modyak is aimed at individual developers and small teams who want to compare models, cut token costs, keep data inside the EU, or run fully offline. It is free, needs no account, and supports both Apple Silicon and Intel Macs. Compared with general-purpose LLM gateways or proxy servers, it trades breadth and team features for simplicity: it is a desktop utility for a specific job rather than a hosted routing platform. Users on Windows or Linux are outside its scope, since it is a macOS app only.

How do you use Modyak?

1Download the macOS app
Get the Modyak installer from the download page. It supports both Apple Silicon and Intel Macs and needs no account.
2Check provider setup notes
Review the providers page in the knowledge base to see what each backend, such as OpenRouter or Groq, requires before use.
3Pick a preset from the menu bar
Open Modyak from the menu bar and choose a preset, for example the DeepSeek and Kimi cost-performance option or local Ollama.
4Launch your agent
Start Claude Code or Codex CLI in the terminal. The session should indicate it is running via Modyak with the selected model.
5Switch presets as needed
Change presets from the menu to compare models or move to an EU-hosted or local option without editing configuration.
