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.
Agent wiki and visual workspace for Claude Code and Codex
A plugin for Claude Code, Codex, Cowork, Cursor, VS Code or any MCP agent that turns your agents' work into editable pages covering decisions, open questions and project context.
Tasks, docs, wiki, diagrams and code share one window, so you can think and direct work without hopping between tools.
Organize agent work on a board and edit documentation or code directly in the app.
Maps how decisions, pages and questions relate so you can see the whole project at a glance.
Provides an AI-native coding IDE, but lacks Nimbalyst's dedicated agent decision wiki and project workspace.
