then for capability.
Start with T3 Code and Paseo. Compare bb for programmability and Orca for an extensive integrated workbench.
Choose Capy as a separate trial if you want hosted coordination across your machines and cloud environments. Paradev and Traycer deserve attention for paid remote and team workflows.

Read “remote” carefully
Five different promises
Remote execution
Agents run on your server, beside its dependencies, datasets and GPUs.
Shared control
Another laptop or phone can control the same server-owned work.
Conversation recovery
Saved history helps an agent resume after an interruption.
Process survival
The actual command continues while you disconnect or close a client.
Work migration
Files and context move to a different execution machine.
A worktree is not a sandbox. Separate Git working folders do not isolate GPU memory, credentials, ports, databases or background processes. A saved conversation does not mean a running job survived a reboot.
Make the decision concreteRun one fair trial.
Run one fair trial.
Measure your review time.
Use the same repository, agents and models. Start with T3 Code and Paseo; add a challenger only when it solves a specific gap.
Success means accepted changes with less review and recovery work—not a larger agent count.
- Run two independent changes on one Linux server in separate worktrees.
- Use one implementation agent and a different review agent.
- Close laptop A; continue from laptop B and a phone.
- Answer an approval, inspect a diff and access a forwarded port.
- Test network loss, service restart and host reboot separately.
- Check processes, history, files, approvals, schedules and billing.
- Finish a PR through existing checks. Record review time and recovery failures.
Several devices is not the same as several people.
Many products share one trusted user’s machines well without providing separate identities, permissions, audit trails or centralized policy. Capy, Paradev and Traycer have more explicit team workflows. Emdash 2.0 advertises broader controls, but availability needs verification.
For AI projects, also test large ignored datasets, model files, Python environments, GPU contention and secrets. Moving a conversation rarely recreates all of that state.
A research snapshot, not a lab benchmark.
How this was researched
One dedicated Codex GPT-6.1 Sol researcher, using High reasoning, investigated each of the 14 products. Research was synthesized around an individual AI engineer with multiple devices and headless development servers, with a secondary team perspective.
Findings were checked on November 13, 2026. This site preserves that Q4 snapshot; it does not update prices or product status automatically.
How to read the evidence
Official documentation supports capability claims. User reports identify specific experiences and failure modes; they do not establish prevalence. Vendor testimonials are labeled separately. Main-branch documentation can describe features ahead of a stable release.
These tools were not hands-on benchmarked for this comparison. Unverified pricing, beta features and unavailable capabilities are identified rather than scored as facts.
What changed from the original tier list?
The source image is a starting list, not our scoring rubric. This guide weights server ownership, shared control and recovery more heavily than interface polish. Conductor’s revised announcement supersedes stale shutdown claims. Emdash Classic and 2.0 are separated, and older Traycer extension reviews are distinguished from its current desktop product.
