Run 10+ parallel coding agents simultaneously on your machine. Switch between tasks seamlessly while agents work in isolated environments with universal IDE compatibility.

Transform your coding workflow by running multiple AI agents in parallel on your local machine. No more waiting for one agent to finish before starting another task.
Key Benefits:
Perfect for developers who want to:
Built for the AI era, Superset enhances your existing tools rather than replacing them, providing better UX and parallelization capabilities that work seamlessly with your current development setup.
Desktop app that runs 25+ coding agents simultaneously, each isolated in its own Git worktree, so you can orchestrate code changes without switching tools.

Emdash is a desktop app for developers who want to run multiple coding agents at the same time without juggling terminal windows or context-switching between tools. Each agent gets its own isolated Git worktree, so parallel sessions don't collide. You orchestrate from a single dashboard.
The core idea is agent-native development. Instead of writing code yourself and occasionally asking an AI for help, you direct agents to do the work while you manage the flow. It's a different mental model from a traditional IDE or an AI-assisted editor like Zed.
What it supports:
The worktree-per-agent approach is what separates Emdash from simply running Aider or Cline in multiple tabs. Each session is genuinely isolated at the filesystem level, which matters when agents are making overlapping changes across a codebase.
It's a macOS and desktop-native app, designed for individual developers who want to scale their output by running agents concurrently rather than sequentially. The app is fully open source and free to use.
Desktop coding workspace that connects to AI subscriptions you already have, with parallel agents, worktrees, one-click PRs, and multi-project management.

Synara is a desktop coding environment that lets you use the AI subscriptions you already pay for, without adding new accounts or bills. Connect Claude Code, Codex, Gemini, OpenCode, Cursor, or Grok and run them all from a single window.
The core idea is parallelism. Instead of one agent, one task, one terminal, you can run multiple agents across multiple worktrees across multiple projects at the same time. Each thread keeps its own state, so nothing gets lost when you switch focus.
Key capabilities:
Synara is free and open source. It's built for developers who already subscribe to one or more AI coding tools and want a single place to run them together rather than juggling separate interfaces.
