* perf(relay): keep the PTY replay window as chunks, not a re-sliced string appendReplayBuffer did `buffered += data` then `buffered.slice(-REPLAY_BUFFER_MAX)` once over the 100KB cap. It runs per raw node-pty emission -- before batching -- so once a PTY saturates the window (which a long-lived shell does almost immediately) every subsequent chunk copied the whole 100KB. Reuse RecentPtyOutputBuffer, which already solved this shape in the main process: keep chunks, drop from the head, defer the join to read(). The relay's three readers are attach, adopt, and revive only. 66-205x on the append path, per PTY, on the user's SSH host. RecentPtyOutputBuffer's limit is now configurable, because the relay retains 100KB where the main process retains 64KB. One arithmetic branch still used the hardcoded constant after that change and silently under-retained (100,800 of 102,400 code units); the equivalence tests caught it before it shipped, and the suite now pins the configured limit directly. Co-authored-by: Orca <help@stably.ai> * test(relay): exercise a real surrogate split; drop eval from the benchmark Review feedback, both valid: - The surrogate test never split a pair. The cap is even and a pair is two code units, so an emoji run alone always cuts on a pair boundary. A trailing single unit shifts the cut mid-pair, leaving a dangling low surrogate (0xDE00) -- asserted directly now, with the boundary-aligned case kept as its own test. - Parse REPLAY_BUFFER_MAX as a product instead of eval(). The regex already admits only digits, spaces and `*`, and eval tripped Biome's noGlobalEval regardless of the eslint suppression.

Features
Mobile CompanionMonitor and steer your agents from your phone — get notified when an agent finishes and send follow-ups from anywhere. |
|
Parallel WorktreesFan one prompt across five agents, each in its own isolated git worktree — compare the results and merge the winner. |
|
Terminal SplitsGhostty-class terminals with WebGL rendering, infinite splits, and scrollback that survives restarts. |
|
Design ModeClick any UI element in a real Chromium window to send its HTML, CSS, and a cropped screenshot straight into your agent's prompt. |
|
GitHub & Linear, NativeBrowse PRs, issues, and project boards in-app — open a worktree from any task and review without a context switch. |
|
SSH WorktreesRun agents on a beefy remote box with full file editing, git, and terminals — auto-reconnect and port forwarding included. |
|
Annotate AI DiffsDrop comments on any diff line and ship them back to the agent — review, edit, and commit without leaving Orca. |

Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
