DeepViewer v0.1.1 has passed Apple notarization. Download only from the official
Release and verify SHA-256 before opening it. If a checksum does not match,
delete the file and do not run it.
DeepViewer is an independent, open-source desktop agent workspace built on DeepSeek Harness. It bundles the pinned local runtime into a normal macOS application and provides a desktop shell designed for a visual, controllable agent experience.
Note
DeepViewer is a community project. It is not affiliated with or endorsed by DeepSeek.
Important
v0.1.1 is a Developer ID signed and Apple-notarized macOS UI preview. It has
passed the maintainer's initial visual acceptance, but it is still an early
preview rather than a stable release.
| Desktop first | Launch the agent as a normal macOS application without manually running Node, npm, pnpm, or a Web UI command. |
| Self-contained runtime | Ships the pinned Harness runtime and compatible execution environment inside the application. |
| Native Mac packages | Provides separate arm64 and x64 packages for Apple Silicon and Intel Macs. |
| Integrated macOS shell | Uses native traffic lights inside the application, a full-width drag region, and a Codex-style collapsible sidebar. |
| Local by default | Runs Harness on a random 127.0.0.1 port and does not expose the service to the LAN. |
| Controlled lifecycle | Starts, health-checks, monitors, retries, and stops Harness together with the desktop application. |
| Clean public artifacts | Rebuilds each public package from allowlisted inputs and blocks releases containing developer paths, settings, or credential values. |
| Spec driven | Keeps product intent, architecture, implementation tasks, and verification evidence in a committed SDD system. |
- Download the package that matches your Mac from the v0.1.1 release.
- Open the DMG and copy
DeepViewer.appto Applications. - Open DeepViewer. It starts the bundled Harness automatically and loads the local workspace when the runtime is ready.

The release also includes a

manifest for command-line verification.
Note
Both official DMGs have passed Apple notarization. An unexpected security warning or checksum mismatch should be treated as a failed download.
- Integrated the native macOS traffic lights into the app surface and removed the separate system title bar.
- Added a Codex-style sidebar control beside the traffic lights. Collapsing now hides the entire sidebar, and the control moves left when native fullscreen hides the traffic lights.
- Reserved a full-width top safe area so window controls, page actions, and the draggable region do not overlap.
- Unified the application name and Dock identity as
DeepViewer, using the maintainer-provided macOS 26 icon. - Added a centered DeepViewer startup surface with a blinking cursor line and a
separate plugin-loading surface with a stable logo and
Loading Plugins...text shimmer. - Added release privacy gates: every public architecture is rebuilt from a clean runtime and allowlist staging directory, then audited before its DMG is created.
- Generated fresh, architecture-specific arm64 and x64 DMGs for 0.1.1.
- Both architecture packages have passed Apple notarization.
- The x64 build passes architecture, package, and Rosetta-based validation on Apple Silicon; physical Intel Mac acceptance remains pending.
- DeepViewer currently customizes the desktop shell around the upstream Harness workspace. More navigation, onboarding, and differentiated agent features are planned.
- Windows packaging, automatic updates, crash reporting, and a stable support policy are not included in this preview.
- The complete bundled runtime keeps each DMG large; runtime size optimization is deferred until the product path is stable.
- Harness listens only on a randomly assigned loopback address.
- The desktop window rejects unexpected navigation and new windows.
- Harness telemetry is disabled by the desktop launch configuration.
- The Renderer receives only an allowlisted desktop bridge; it does not receive general shell or filesystem access.
- Logs redact common authorization headers, API-key assignments, and secret-like values.
- Public packages are created from a clean allowlist staging directory. The build removes package-manager workspace metadata and blocks developer home paths, personal settings files, and current environment credential values.
- DeepViewer does not add the developer's or maintainer's local sessions, workspace, logs, settings, or API credentials to release assets.
For the prebuilt application:
- A Mac with Apple Silicon or an Intel processor.
- No global Node.js, npm, pnpm, or DeepSeek Harness installation is required.
- macOS 10.15 or later is recommended for the standard notarized Developer ID installation path.
For development:
- Node.js 24 or later.
- pnpm 11.19.0.
