Emdash is an open-source desktop app for running multiple coding agents in parallel; one place to monitor sessions, review diffs, and turn issues into PRs.
One app for several coding agents gets really useful when the handoff is explicit instead of implied. The part I would watch closely is provenance: which agent proposed the change, what evidence it saw, what diff it produced, and why the next agent or human reviewer is allowed to continue from there. Cross-agent speed is great, but the review surface has to stay legible.
Tried out Emdash today, thoroughly impressed! Was having some initial setup hiccups when installing the agents on Window, but had a successful run at the end. Running tasks in parallel was not only time saving but conducted a fun experiment asking 2 different agents to work on the same task and compared their outputs to determine which agent did better for that particular workflow. Does Emdash store any history of which agents performed better on which task type? Would be interesting if it could surface patterns over time so agent selection becomes data-driven rather than purely manual!
Interesting seeing the shift from IDE-centric AI tooling to agent orchestration layers. Curious how you think Emdash evolves once agents start depending on outputs from each other, not just running in parallel. Does coordination between agents become part of the product long term?
the parallel agents angle is the part worth exploring. running multiple coding agents simultaneously sounds powerful until you hit merge conflicts from two agents touching the same files. curious how Emdash handles that, is there any coordination layer between sessions or is it essentially isolated workspaces that you reconcile manually through the diff review
When multiple agents are working on related parts of the same codebase in parallel, how does Emdash handle potential conflicts — does it surface them before you hit merge, or is that left to the user to catch?
Provider-agnostic is the right bet here. Most teams I know are running Claude Code in one repo and Copilot in another, and the context switching is real. Having one desktop window to watch all agents is a workflow I didn't know I needed until I saw this.
The SSH remote execution feature is underappreciated in the description. Running Claude Code on a beefy remote machine rather than a developer's laptop changes the cost/latency profile significantly, especially for large monorepos where context loading is slow. How does Emdash handle the agent state across an SSH disconnect? If a developer closes their laptop mid-session, does the agent continue running remotely and the session resumes on reconnect, or does the disconnect kill the agent?
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!
