There is something you are not explaining (at least I couldn't find it, sorry if you do), but how do you manage apps states? Basically databases?
Most of these agents solutions are focusing on git branches and worktrees, but at least none of them mention databases. How do you handle them? For example, in my projects, this means I would need ten different copies of my database. What about other microservices that are used, like redis, celery, etc? Are you duplicating (10-plicating) all of them?
If this works flawlessly it would be very powerful, but I think it still needs to solve more issues whan just filesystem conflicts.
Great question currently superset manages worktrees + runs setup/teardown scripts you define on project setup. Those scripts can install dependencies, transfer env variables, and spin up branching services.
For example:
• if you’re using Neon/Supabase, your setup script can create a DB branch per workspace
• if you’re using Docker, the script can launch isolated containers for Redis/Postgres/Celery/etc
Currently we only orchestrate when they run, and have the user define what they do for each project, because every stack is different. This is a point of friction we are also solving by adding some features to help users automatically generate setup/teardown scripts that work for their projects.
We are also building cloud workspaces that will hopefully solve this issue for you and not limit users by their local hardware.
Why aren’t you mocking your dependencies? I should be able to run a microservice without 3rd party and it still work. If it doesn’t, it’s a distributed monolith.
For databases, if you can’t see a connection string in env vars, use sqlite://:memory and make a test db like you do for unit testing.
For redis, provide a mock impl that gets/sets keys in a hash table or dictionary.
What higher fidelity do you get with a real postgres over a SQLite in memory or even pglite or whatever.
The point isn’t you shouldn’t have a database, the point is what are your concerns? For me and my teams, we care about our code, the performance of that code, the correctness of that code, and don’t test against a live database so that we understand the separation of concerns between our app and its storage. We expect a database to be there. We expect it to have such and such schema. We don’t expect it to live at a certain address or a certain configuration as that is the databases concern.
We tell our app at startup where that address is or we don’t. The app should only care whether we did or not, if not, it will need to make one to work.
This is the same logic with unit testing. If you’re unit testing against a real database, that isn’t unit testing, that’s an integration test.
If you do care about the speed of your database and how your app scales, you aren’t going to be doing that on your local machine.
Use review bots (CodeRabbit, Sourcery and Codescene together work for me). This is for my own projects outside of work, of course. I use Terragon for this. 10 parallel rust builds would kill my computer. Got a threadripper on its way through, so superset sounds like something I need to give a go.
The real bottleneck isn’t human review per se, it’s unstructured review. Parallel agents only make sense if each worktree has a tight contract: scoped task, invariant tests, and a diff small enough to audit quickly. Without that, you’re just converting “typing time” into “reading time,” which is usually worse. Tools like this shine when paired with discipline: one hypothesis per agent, automated checks gate merges, and humans arbitrate intent—not correctness.
In the past I've worked with devs who complain about the cost of context switching when they're asked to work on more than one thing in a sprint. I have no idea how they'd cope with a tool like this. They'd probably complain a lot and just not bother using it.
Noticed this is built with electron (nice job with the project architecture btw, I appreciate the cleanness), any particular reason a Windows build isn't available yet?
We do plan to ship Windows (and Linux) builds, Electron makes that feasible, but for the first few releases we focused on macOS so we could keep the surface area small and make sure the core experience was solid since none of us are using Windows or Linux machines to properly test the app in those environments.
But it on the roadmap and glad to know theres interest there :)
Thanks for the question. For most traditional web apps using frameworks like Next.js, Vite, etc they'll automatically try the next port if its in use (3000-> 3001 -> 3003). We give a visualization of which ports are running from each worktree so you can see at a glance whats where.
For more complex setups if your app has hardcoded ports or multiple services that need coordination you can use setup/teardown scripts to manage this. Either dynamically assigning ports or killing the previous server before starting a new one (you can also kill the previous sever manually).
In practice most users aren't running all 10 agent's dev servers at once (yet), you're usually actively previewing 1-2 at at time while the other are working (writing code, running tests, reviewing, etc). But please give it a try and let me know if you encounter anything you want us to improve :)
I’ve been following this space and a lot of good apps:
Conductor
Chorus
Vibetunnel
VibeKanban
Mux
Happy
AutoClaude
ClaudeSquad
All of these allow you to work on multiple terminals at once. Some support work trees and others don’t. Some work on your phone and others are desktop only.
My issue with most of them is the xterm.js, which can't handle when the terminals get large/too big, Even Conductor (great app, i love conductor and the team behind it) had to drop their "big-terminal" mode. i'm hacking a native solution for this which i personally like by hacking Ghostty+SwiftTerm.
Agent orchestration CLI tools are the new Javascript frameworks

Stop bringing your whole house to the camp site.
Because the real thing is higher fidelity, but it can expensive to boot up many times.
Higher fidelity?
What does that mean in this context?
What higher fidelity do you get with a real postgres over a SQLite in memory or even pglite or whatever.

pglite might be an option.
Recently gave Catnip a try and it works very smoothly.

How is this different?
How are people productive using 10 parallel agents? Doesn’t human review time become a bottleneck?
Use review bots (CodeRabbit, Sourcery and Codescene together work for me). This is for my own projects outside of work, of course. I use Terragon for this. 10 parallel rust builds would kill my computer. Got a threadripper on its way through, so superset sounds like something I need to give a go.
Running into this issue with just 1 agent. I have plenty of tokens to spare. Just not enough time to iterate and bugfix.
The real bottleneck isn’t human review per se, it’s unstructured review. Parallel agents only make sense if each worktree has a tight contract: scoped task, invariant tests, and a diff small enough to audit quickly. Without that, you’re just converting “typing time” into “reading time,” which is usually worse. Tools like this shine when paired with discipline: one hypothesis per agent, automated checks gate merges, and humans arbitrate intent—not correctness.
IDK what everyone is doing anymore. Just why do you need 10 parallel agents doing things. How is this even a possible workflow for a person.

I have a question: How do you manage web servers running parallely for 10 coding agents?
Thanks for the question. For most traditional web apps using frameworks like Next.js, Vite, etc they'll automatically try the next port if its in use (3000-> 3001 -> 3003). We give a visualization of which ports are running from each worktree so you can see at a glance whats where.

Run them on different ports?
I’ve used superset at work this last week, and it’s great! Excited to see what’s next!
Thanks! love to hear it :)

Superset seems like a great addition!
Thanks we're totally open source too! so you can check us out on github too https://github.com/superset-sh/superset

Same my friend, I'm building a custom frontend for Vibetunnel that uses ghostty-web[0] instead of xterm!

Not to be confused with Apache Superset (data visualization solution)

correct :)
