Frequently Asked Questions

TatsuCode is free to download and use. You only need an API key (OpenRouter) or existing subscriptions to supported providers like OpenAI, Google, and GitHub Copilot. You can also run models locally with Ollama, LM Studio, or llama.cpp. This makes it possible to use TatsuCode 100% free with local models. If you find TatsuCode valuable, donations help support ongoing development.
Use the tool that best fits your workflow. TatsuCode offers freedom to choose from 200+ models via OpenRouter, works with existing subscriptions, requires zero installation, and is built natively for Windows. No vendor lock-in. Switch providers anytime. It's also a great entry point to agentic coding for Windows developers who haven't used CLI-based tools.
Most agentic tools are built for Mac/Linux first, with Windows as an afterthought. TatsuCode flips that. It's built natively on Windows, for Windows, using .NET. This means better integration, no WSL or Node.js required, and Windows developers aren't second-class citizens.
UI/UX. Image previews, dropdowns, dynamic modals, easier message editing. A GUI offers a better experience while maintaining keyboard-first controls. TatsuCode is a hybrid: desktop chat with terminal-style workflow. ESC closes windows, slash commands for everything.
One sentence: "Reviewing 1,000+ AI-generated pull requests..." No thank you. Quality control and security are priorities. Feature requests are welcome and get implemented when valuable.
Nothing. Zero telemetry. Your chats, sessions, and API keys are stored locally on your machine (keys are encrypted). TatsuCode has no servers collecting your data. For privacy concerns about specific AI models, check the provider's terms directly.
TatsuCode is a solo-developed project. Countless weekends and late nights, with TatsuCode agents helping along the way. Built by a developer, for developers.
Head over to the TatsuCode GitHub repository for bug reports, feature requests, and community discussion. Note: TatsuCode is closed source. The repository is for issue tracking and feedback, not source code.
