Scores by category

Rubric breakdown

Read the scores as a feature assessment. Orca was run end-to-end with stub agents; T3 Code was not run through an equivalent session, so Orca 93 vs T3 Code 90 is a difference in assessed features and evidence, not an experimentally proven gap.

Broadest documented harness list with ACP; best-documented PR flow; strongest remote story. Isolation scored 4 because we could not exercise it.

Verdict

Strengths and weaknesses

Strengths

Event-sourced orchestrator, durable queue, restart recovery (v0.1.0)
delegate_task across providers, plus an MCP that lets agents manage threads
One-click PR with draft and stacked PRs; web and mobile

Weaknesses

We could not run a session here: it controls agents that are installed and authenticated, and none were
2.9k open issues+PRs; v0.1.0 is days old
Users on X report the sidebar gets noisy at scale

Evidence

What we saw and where it came from

Hands-on (this box): Server ran headless on Linux (ready 1.0 s, 394 MB idle). No agent session run (no authenticated agent CLI usable).
Server probe: Headless server port open in 1.01 s, 394 MB idle.
Known issues: Public X thread (Oct 2026) of a user finding sidebar hard to use with hundreds of settled threads; 2.9k open issues+PRs on GitHub.
Notes: v0.1.0 (Oct 15 2026) made Orchestrator V2 stable: event-sourced command log, durable queue, restart recovery.

Sources

Feature facts

From docs, repos and our probes

Platforms: Desktop (Electron: macOS dmg, Windows exe, Linux AppImage/deb), web app, iOS + Android app, headless server binary (linux/mac/win)
Supported agents: Claude Code, Codex, Cursor (via Cursor SDK), Grok Build, OpenCode (incl. OpenCode 2), Google Antigravity, Pi, Muse Code, any ACP Registry agent (Devin, Cline, Kimi, Droid...)
Parallelism: Threads per agent; each thread writes to its own branch; MCP tool to hand work off to a worktree; delegate_task child agents across providers
Isolation: Git branch/worktree per thread (vendor docs). Not containers.
Review, merge, PR: Inline diff review, one-button commit/push/PR with generated title/body, draft + stacked PRs
Remote, cloud, mobile: Strong: web, mobile, remote environments over authenticated RPC, Tailscale Serve flag, background service
MCP: Yes: T3 Code MCP (agents create/launch/message/wait/interrupt threads)
Cost visibility: Partial: usage chart in mobile, 'Limited' state + auto-resume when provider limits reset
Model choice: Per provider; switch provider/model mid-thread (with caveats)
Setup: Download app, or single headless binary: `t3 serve`
