Top comment

Hey Product Hunt! 👋

We’re super happy to show you Emdash today.

One app, every coding agent.

Emdash is a provider-agnostic desktop app to run agents in parallel and turn issues into PRs.

Some features:

  • Run multiple agents in parallel with isolated worktrees

  • Use any of 28+ coding agent providers

  • Pass issues from Linear, Asana, Featurebase, GitHub, …

  • Run agents on remote machines via SSH

  • Review diffs and ship PRs in-app

  • BYOI: provision per-task workspaces on your own infrastructure

  • Available on macOS, Windows, and Linux


We're excited to see what you're going to build with Emdash!

Comment highlights

first time using emdash genuinely blew my mind.
felt like getting a glimpse into how coding will work in 5 years.

Managing multiple coding agents from one place is the right idea - context switching between Claude Code, Codex, and others is its own overhead. Does it unify the context/memory across agents or mostly just the interface?

I LOVE using emdash. Its 10xed my workflow and could not live without. Thanks for pushing so frequently team!

Congrats on the launch. The worktree + PR handoff is the part I’d try first. One thing I’m curious about: when several agents touch adjacent files, does Emdash help compare runs and trace which prompt or session introduced a change, or is the review flow mainly diff-first today?

Feels like an actual coworker!! What's the practical ceiling on parallel agents per machine before things degrade? Are you seeing teams run 3-5, or 10+?

The multi-agent parallel workflow is where this gets interesting. Right now most people just use one coding agent at a time because managing context across multiple sessions is a mess. Having a single place to review what each agent did and catch conflicts before they hit a PR is the part that's actually hard to replicate with just terminal tabs. Do you find people naturally end up specializing different agents for different tasks, or do most users run the same agent in parallel on separate features?

I saw AntiGravity recently went in the same direction as of yesterday. They basically removed the IDE part and doubled down on Agent control tower. How is emdash different from AntiGravity?

Been using the app for a little over 2 months now and I genuinely think this is the best tool for multiple worktrees. Such a huge time saver. Happy launch day!

Been using it for the past couple of months, and it is as close as it gets to an agent-agnostic mission control center. Sleek, open-source, and continuously improving. Great for those of us who juggle between providers and agents, and want to manage different terminal views for them in a sane way. Congrats on the launch!

Congrats on the Launch!

I love using Emdash myself, I feel like it gives me back some mental space with our agents running :)

I've been using emdash for the past week and have loved it.

Before this, I’d looked into using git worktrees to run more agents in parallel, but the extra workflow overhead made it hard to justify adopting them day to day.

Emdash abstracts all of that away. It makes spinning up parallel agents feel simple and natural.

You can also feel the craft in the product. Little touches like creating an agent from a GitHub issue, the animations, and the sounds make the app genuinely enjoyable to use.

If you want to run multiple agents in parallel and let them rip, I highly recommend trying Emdash.

I have been using Emdash for three months now and I really like it! Compared to other agentic development environments, Emdash is the best fit for my workflow. It makes me much faster because it's so easy to work on multiple things at once in different worktrees or run different agent sessions in parallel in the same worktree 👏

Very big fan of Emdash. It's been incredible seeing how fast the team is shipping new features and expanding it. I love how I can run my agents in parallel and also across different models. Finally, I don't have to migrate back and forth between Claude Code and Codex every month.

Congrats on the launch! Parallel agent sessions with a unified diff view is exactly where the workflow needed to go. The PR-from-issue flow is particularly smart for async teams. What's the mental model for context isolation between sessions?

Nice. That can make my life much easier. What features that come up in the next few weeks are you most excited about? Can you share a bit more about the roadmap?
