Free, open-source, local-first developer workspace for snippets, notes, APIs and diagrams
Organize reusable code fragments in nested folders, tag them for fast filtering, and jump to anything through a keyboard-driven command palette.
Write Markdown notes, explore connections between them in a graph view, and turn notes into tasks with status, priority, due dates and links to related snippets and requests.
Save API requests, run them in sequence, pass values between steps, and inspect responses or JSON diffs without leaving the app.
Connect OpenAI, Anthropic, Gemini, DeepSeek, Mistral, xAI or OpenRouter with your own key, or use a local Ollama/LM Studio model, to edit code, reorganize notes and test APIs. An MCP server exposes the same vault to external AI agents.
An AI IDE and coding agent that works on your project, not just your cursor
Trae reads your project files and dependencies, so its suggestions account for how the codebase is actually structured rather than treating each file in isolation.
Describe a task and the agent plans and applies multi-file edits, shows a diff for review, and can run terminal commands as part of the change.
Ask questions about unfamiliar code, get inline explanations, and have bugs or failing tests diagnosed and fixed with context.
TraeCode covers the coding workflow, while TraeWork applies an AI assistant to everyday knowledge tasks — both download for desktop, with a web option.
