@neil_parker9 We run parallel Cursor and Windsurf sessions all day building TAB Platform. The disorganization is real. Will check this out. Congrats on launch.
@neil_parker9 Hi. With 10 parallel agents running, can I really pause one without breaking the rest?
@julia_zakharova2 They're all isolated, so 100% yes
It should just work, but if you run into any snags, let me know!
@neil_parker9 I'm using Orca now and it's been a huge boost at visibility and workflow. It's like t3 code but smoother and more QOL features. Great work and looking forward to continued development
The amount of code I pushed out went up almost 3x since last month since going from Cmux to Orca.
I thought I knew why. Orca was making it easier to run more agents at once!
Nope. On a typical day the most I had running at the same moment was 7 (either in Orca or Cmux -- analyzed 1-month of data each)
What changed is that I ran 1,766 Claude sessions in September against 609 in August, and each one was less than half as long. They're spread across 206 worktrees, up from 31 worktrees in August. 374 PRs in August vs 198 PRs in September.
The other change I think is permissions. Orca launches every session with `claude --dangerously-skip-permissions`. That's the default (!) In August, cmux + auto-classifier was in 55% of my sessions. Now in September it's down to 10%, so it looks like the auto-classifier was slowing me down.
Love Orca. Bye bye Cmux (it was good while it lasted!)
Worktree-per-agent feels like the right primitive. Curious how Orca handles disk cleanup when you keep several worktrees alive, especially JS repos where each one may end up with its own node_modules.
I’m trying it out following a colleague's recommendation, and it’s a really great project—plus, it’s open source and free. It definitely represents a real step forward in how we use IDEs and develop our projects. Git worktrees are seamlessly integrated; as someone who hadn't really used them in a practical setting before, I find the setup perfect for working on multiple tasks simultaneously using multiple agents.
One last thing I struggled a bit in my case is to have to use SSH because of WSL2, but I checked and it seemed to be plan to have a real WSL remote integration, looking forward to this !
I'm currently using cmux, but Orca looks way cooler and more user-friendly. I'll definitely give it a try and let you know what I think.
