## massCode

massCode started life as a code snippet manager and has grown into a full local-first developer workspace. Around a single vault of plain files it bundles a snippet organizer with folders and tags, a Markdown note system with graph view and task tracking, an HTTP client that can chain saved requests into multi-step API workflows, Excalidraw-powered drawings, a math notebook with variables and unit conversion, and small utilities such as JSON diff and encoders.

The workspace is deliberately local and portable. Snippets, notes and requests are saved as Markdown and code files inside a folder you choose, and drawings use the open Excalidraw format, so you can open the vault in other editors and sync it with iCloud, Dropbox, Syncthing, Git or any other file-sync tool you already trust. Nothing depends on a proprietary cloud account.

Since its recent versions massCode also ships a built-in AI assistant. You bring your own key for OpenAI, Anthropic, Gemini, DeepSeek, Mistral, xAI or OpenRouter, or run a local model through Ollama or LM Studio, then ask the assistant to edit snippets, reorganize notes, update task properties or exercise an HTTP collection. An MCP server lets external AI clients such as coding agents read snippets and notes and run requests from the same vault. massCode is licensed under AGPL v3 and free to download.

**Pricing & Plans:** massCode itself is free and open source (AGPL v3) with no paid tiers. If you use a cloud AI model, you pay your own model provider for API usage; local models via Ollama or LM Studio have no extra cost.

- **Snippet manager with folders and tags:** Organize reusable code fragments in nested folders, tag them for fast filtering, and jump to anything through a keyboard-driven command palette.
- **Notes, graphs and task tracking:** 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.
- **HTTP client with multi-step workflows:** Save API requests, run them in sequence, pass values between steps, and inspect responses or JSON diffs without leaving the app.
- **Built-in AI assistant and MCP:** 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.
- **Plain-file, local-first vault:** Everything is stored as Markdown, code and Excalidraw files in a folder you control, so sync via iCloud, Dropbox, Syncthing or Git is up to you.

**Strengths:** Free and open source under AGPL v3, with no subscription; Local-first plain-file vault you can sync and back up however you like; Unusually broad toolset: snippets, notes, HTTP client, diagrams, math, JSON tools; Bring-your-own-key AI plus Ollama and LM Studio support avoids vendor lock-in

**Limitations:** Requires a desktop install; there is no browser-only version; AI features only become useful once you supply your own API key or local model; The sheer number of modules can feel overwhelming at first

## Nimbalyst

Running coding agents is easy; keeping track of what they did is not. Nimbalyst addresses that gap from two directions. The Wiki is a lightweight plugin for Claude Code, Codex, Cowork, Cursor, VS Code or any MCP-compatible agent — as your agents work, they record the decisions they made, the questions still open and the big picture into structured pages you can read and edit. No account or separate app is required to use it.

The Nimbalyst App goes further with a desktop workspace: a Kanban board for tasks, a Markdown and code editor, a diagramming surface and the wiki itself, all in one window. Because agents can add what they learn as they work, nobody has to hand-write the project page, and open questions surface as items that need a decision. A Context Graph feature ties the relationships between pages together.

Nimbalyst also ships a Wiki Teams layer for groups: each teammate's agent contributes to one shared wiki, pages are edited together in the browser in real time, and you can see which decisions are made, by whom, and which are still pending. The personal wiki and app remain free for individuals; Wiki Teams is the paid plan and is free while in beta. The company also publishes open-source components and SOC-2 Type 2 compliance information.

**Pricing & Plans:** Free for individuals. The Nimbalyst App and the personal wiki plugin cost nothing and run locally. Wiki Teams is the paid plan for sharing a wiki across a team, and is free during its beta period.

- **Agent-written wiki:** 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.
- **Visual desktop workspace:** Tasks, docs, wiki, diagrams and code share one window, so you can think and direct work without hopping between tools.
- **Kanban and Markdown editor:** Organize agent work on a board and edit documentation or code directly in the app.
- **Context Graph:** Maps how decisions, pages and questions relate so you can see the whole project at a glance.
- **Shared Wiki Teams:** Every teammate's agent contributes to one wiki, edited live in the browser, with visibility into who decided what.

**Strengths:** Free, local and open source for individual use; Works with your existing Claude Code or Codex subscription and API key; Wiki plugin needs no account and supports any MCP-compatible agent; Combines task board, editor, diagrams and wiki in a single workspace

**Limitations:** Aimed squarely at agent-driven development, so it adds little for teams not using coding agents; Wiki Teams is still in beta and free only during that period
