* perf: stop host-status pings rebuilding the title catalog and rereading server config Host-status updates walked every saved tab for title-refresh support before checking whether any host's support changed, and remote RPC/tunnel/worker checks reread, rehardened and reparsed the saved-server registry files on every call. Gate the title walk on an actual per-host capability flip, and reuse the merged registry read while a stat signature of its three files is unchanged. * perf: invalidate registry read cache on in-process writes Coarse-timestamp filesystems can reuse an inode within one tick, so a same-size rewrite could slip past the stat signature; writers in this process now bump a generation that is part of the signature. * perf: key the registry read cache on file bytes, not stat metadata A stat signature can miss a same-size rewrite on coarse-timestamp filesystems or a reused inode. Comparing the files' exact bytes (plus mode/ctime and the directory mode, which the uncached read re-hardens) means a hit can never serve data that differs from disk, from any writer. * perf: only reuse a registry read once hardening holds and the path is unchanged Reuse now requires the files' permissions to already be restricted (POSIX), so a transient chmod failure is retried on the next read as before; Windows hits keep the ACL verify-and-retry. Snapshots also record each path entry's identity, so a symlink re-pointed and restored mid-read cannot pin the value read through the other target. * perf: build the cached registry value from the exact bytes it is keyed on The value was computed by a second, independent read, so a directory or symlink swapped and restored around it could pin data the key's bytes never held. Each reader is split into read + parse-text, and on a miss the cache hardens, snapshots once, and parses that snapshot. Reuse also now requires the exact 0600/0700 modes the readers set, so an incomplete owner mode is repaired as before. * perf: require the full hardened mode, including special bits, before reusing a registry read * perf: keep Windows on the plain registry reader Measured on a Windows host: a cache hit still has to re-verify ACLs, so it cost as much as the read it skipped (0.37 ms vs 0.33 ms). Windows now always uses the original reader, keeping its behavior byte-for-byte unchanged.

Features
Orchestrate AgentsHand a big task to one agent. It splits the work, starts worker agents in their own workspaces, and brings their results back to you. |
 |
Chat or TerminalRun any agent in Chat UI or as the raw CLI, and move a conversation between the two without losing context. |
 |
Run AnywherePair a Remote Orca Server, work on any SSH host, or give a worktree its own cloud VM. Your agents keep running when your laptop sleeps. |
 |
Mobile AppPair Orca with the mobile app to get pinged when an agent needs you, reply in chat, and keep work moving on any of your machines when you are away from your desk. |
 |
Review AI OutputReview diffs, leave notes on exact changed lines, and send focused feedback back to an agent. |
 |
Git IntegrationDraft commit messages and pull requests from the diff, then send failing checks or PR review comments back to an agent to fix. |
 |
Parallel WorktreesQuickly split tasks into isolated environments, so multiple agents can work side by side without interfering with each other. |
 |
Design ModeClick any element in Orca's browser to copy its HTML, styles, and selector, then paste it into your agent's chat. |
 |
GitHub & Linear, NativeSee your GitHub and Linear tasks in one place, and start a workspace for each when you're ready to build. |
 |
Orca CLIAnything you can do in Orca, your agents can do too: create worktrees, start workers, drive the browser and desktop apps, and schedule automations, all from the command line. |
 |
PluginsThemes, editors, languages, and panels from the community, installed in a click. |
 |
Split AnythingPut agents, terminals, browsers, and diffs side by side in split panes shaped to the task. |
 |
Also in the box:
- Drag Files to Agents: drag files from the explorer, or images from your desktop, straight into an agent's prompt.
- Jump Anywhere: one shortcut jumps to any workspace or tab across every repo and host.
- Rich Previews: open images, PDFs, and Markdown right in the workspace, next to the agent that made them.
- Mobile Emulator: run an iOS Simulator or Android emulator beside your agent, and let it tap, type, and check its own work.
- Dictation: press a shortcut and talk. Orca types what you say into the agent's prompt or terminal.
- Usage & Accounts: see how much of your agent limits you've used and when they reset, and switch accounts without logging out.
- Automations: schedule prompts to run on any repo: nightly dependency bumps, weekly triage, flaky-test sweeps.
- Computer Use: when there's no CLI or API, agents can see and drive desktop apps and external browsers.
- And many, many more: we ship daily, so this list is perpetually behind. The changelog is the real feature list.
