Foremerge is an open-source coordination protocol and CLI for parallel coding agents, developed by naw103 and built above Git. It gives agents isolated Git worktrees while recording shared intents, semantic scopes, claims, dependencies, ChangeSets, decisions, validation results, and provenance in a local SQLite store under the repository's Git common directory. Agents publish what they intend to change before editing. Foremerge compares typed scopes such as symbols, APIs, schemas, configuration, infrastructure, tests, migrations, files, components, contracts, and domains, producing deterministic, explainable conflict advisories and related-work information. Claims are leased and advisory rather than exclusive: the system does not lock files, block agents, or ask a model to judge conflicts. Its workflow can publish and validate a ChangeSet against a recorded Git fingerprint, require a clean worktree and resolved high-severity conflicts for acceptance, and record the eventual integration commit without merging, rebasing, cherry-picking, or pushing code. The project provides a Rust CLI, JSON API, MCP server, SQLite coordination store, Git worktree support, and integrations for Claude Code, Codex, and Cursor. It is a local-first pre-1.0 MVP; coordination across machines is outside its scope, validation commands run with the local operating system's permissions, and the project reports no published benchmark results. Foremerge is distributed under the Apache License 2.0.

Hatchdoor is a self-hosted web application and MCP server for Obsidian-style Markdown vaults. It provides a browser interface and an MCP endpoint through which users and AI agents can browse, keyword-search, semantic-search, create, edit, move, and link notes, with wiki links, backlinks, graph views, metadata, Markdown rendering, attachments, and optional Git commits and pushes. Markdown files remain the source of truth; Hatchdoor builds a disposable SQLite read model for browsing, links, search, graph data, and metadata, rebuilding it from the vault if the cache is deleted. It is distributed as a rootless, distroless Docker or Podman container, with MCP and write access disabled by default. Hatchdoor is not a hosted synchronization service or multi-user collaboration platform. The project is licensed under the GNU Affero General Public License v3.0 only.

herdr is a terminal multiplexer and persistent runtime for coding agents, developed as a Rust binary. It runs a background server that keeps agent terminals and sessions available across terminal disconnections, SSH reconnections, network loss, lid closure, and machine restarts; users can reattach from another terminal and use tmux-style keyboard controls or mouse interactions to split, move, and manage panes. Each pane is marked working, blocked, or idle, and agents can control herdr through its CLI and socket API to spawn panes, prompt other agents, and wait for an agent that is blocked. It hosts existing tools such as Claude Code, Codex, Cursor, OpenCode, and Grok without wrapping or replacing them, and supports plugins for extending panes and workflows. The project provides installation scripts and package-manager installation, documents remote use and session state, and is licensed under the Apache License 2.0.

Rust is a systems programming language and toolchain developed by the Rust project. Its compiler, standard library, documentation, package manager and build tool Cargo, formatter rustfmt, linter Clippy, and editor support are maintained in the main repository. The language uses a rich type system and ownership model to enforce memory and thread safety at compile time, while targeting fast, memory-efficient software for critical services, embedded devices, and integration with other languages. Rust is primarily distributed under the MIT and Apache 2.0 licenses, with portions under BSD-like licenses.

Munder Difflin is a free, open-source desktop multi-agent harness that runs multiple terminal-based AI coding agents as coordinated local agents. It wraps agents including Claude Code, OpenAI Codex, Gemini CLI, Qwen, OpenCode, GitHub Copilot CLI, and custom commands, working with users' existing subscriptions and hourly usage limits. Each agent runs as a real node-pty process and is rendered through xterm.js, while an Electron and React interface displays sessions as avatars on a Pixi.js office floor. A GOD orchestrator called Michael assigns and routes work, adjudicates agent messages, and escalates spending, destructive operations, scope changes, and other configured approvals. Agents coordinate through a local Git-backed hive of plain-file memory, atomic mailboxes, a shared blackboard, and an append-only event log; a markdown-first semantic memory layer supports recall across sessions. Optional Git worktrees isolate parallel agents.
