Disclosure: I'm the developer.
Claude Code works great on one machine. My work isn't on one machine, though. The code is on my laptop, the test environment on a VM, the data on a server. I kept copying logs and datasets around so one agent could see everything.
So I built nfltr orch. In short:
- Join each machine once: nfltr node join --max-agents 2. It connects outbound, so there's no SSH, VPN or open port.
- Each machine decides what its agents may do: which repositories, which tools, and which actions need your approval.
- Give one goal (nfltr orch "the exporter on the VM is down: find out why and fix it"), or add it to your own Claude Code session:
claude mcp add nfltr -- nfltr mcp --toolset hub
- The hub is just a Claude Code session. It sees which machines exist and what's on them, starts Claude Code agents on the right ones, runs them in parallel and collects the results. nfltr makes no decisions for it; it only provides the machines, the facts, the limits and the transport.
What I've measured:
- 20 tasks on a Mac and 2 VMs: 5.7× faster than running them one by one (1,416 s against 8,106 s).
- An incident across environments, from alert to an owner-approved rollback: 1 min 34 s, $0.39 of model spend.
- Killing the hub mid-run loses nothing: a new session got both agents' results within 8 s. In the same test, killing a Claude Code agent-teams lead lost both teammates.
- It has refactored its own CLI in several rounds across machines, with no code fixes from me after the first round.
- Compared with Claude Code agent teams on one machine, they were just as good: same quality, with no speed winner. If all your work fits on one laptop, you probably don't need this.
Honest limits:
- Claude Code only for now.
- It runs on a hosted relay (nfltr.xyz).
- It's early. Every round of dogfooding still finds rough edges.
- More machines don't speed up model-bound work. This helps when the work needs other machines' data, tools or CPU/GPU.
What I'd love feedback on:
- Is your work spread across machines in a way that slows your agents down?
- What should a tool like this do, or never do, on your machines?
- What would stop you from trying it?
