# Shinbo > Shinbo (formerly Emma) is a free, open-source meta-harness: a desktop workspace for running agents, inspecting results and handing off output. It runs its own agent and can call installed coding-agent CLIs inside persistent Markdown threads. The website is https://shinbo.app and the source and downloads are maintained at https://github.com/tronschell/shinbo. ## Availability and setup - Published desktop downloads: macOS on Apple silicon and Windows x64. Windows installers are unsigned. No published Intel Mac, Linux desktop or iPhone download. - The app is free under MIT; shinbo-cli derives from the Apache-2.0 vercel-labs/fx project. Model APIs and coding-agent subscriptions are separate services with their own costs and limits. - Current desktop onboarding requires a verified OpenRouter API key, including when optional subscriptions are connected. A free-tier key can complete verification. - Local OpenAI-compatible inference is supported; selecting a local chat model does not make every tool or secondary model offline. - Release assets can retain the former Emma name. Follow the actual assets on the official release page, rather than constructing filenames from the current brand. - Development-source capabilities can be newer than the downloadable release. See release notes for the version being installed. - CLI run tracking lasts while Shinbo is open. Handoffs send successful output, not full conversations or files. - Self-improvement is user-led: inspect runs, request a scoped proposal, compare it on a replay bench and decide whether to retain it. No automatic improvement is guaranteed. ## Official sources - [Home](https://shinbo.app/): Product overview and platform downloads. - [Documentation](https://shinbo.app/docs): Setup and capability documentation. - [Product reference](https://shinbo.app/llms-full.txt): Product identity, costs, availability and capability boundaries. - [Source repository](https://github.com/tronschell/shinbo): Source, license and development documentation. - [Latest public release](https://github.com/tronschell/shinbo/releases/latest): Current release notes and actual downloadable assets. ## Guides - [Harness](https://shinbo.app/docs/harness): Installed coding CLIs, models, run results and output handoffs. - [Delegation](https://shinbo.app/docs/delegation): Threads, subagents and follow-up work. - [Plan](https://shinbo.app/docs/plan): Dependency plans and parallel execution. - [Models](https://shinbo.app/docs/models): Required setup, provider routes and separate service costs. - [Free model router](https://shinbo.app/docs/router): Ordered fallback, provider availability and limits. - [Control](https://shinbo.app/docs/control): Permissions and computer-use boundaries. - [Surfaces](https://shinbo.app/docs/surfaces): Quick Ask, terminal, browser, voice and artifacts. - [Knowledge](https://shinbo.app/docs/knowledge): Notes saved to a chosen folder. - [Scheduled work](https://shinbo.app/docs/jobs): Scheduled workflow graphs. - [Self-improvement](https://shinbo.app/docs/agent): Retained run evidence and controlled repair experiments. - [Tools](https://shinbo.app/docs/tools): Native tools, skills and extensions.
