An independent browser takes up Arc's design ideas

Crest, an independent web browser for Apple devices, has entered early access with an interface explicitly inspired by some of Arc's most recognizable ideas. The project is available for Mac, iPad and iPhone and is licensed under the Mozilla Public License 2.0, according to its official website. Crest says it is not affiliated with Arc.

The browser centers navigation on a calm sidebar rather than a conventional row of tabs. Users can organize work into Spaces, arrange tabs and folders, and open pages in a resizable Split View. A Peek feature provides a way to view a page without fully leaving the current context. In full-screen mode, the sidebar can remain hidden until the user swipes for it.

Crest also offers extensive appearance controls. Its site describes options for changing tab shape, sidebar position, pins, address colors, artwork and trim, with a live preview to show the effect before a choice is applied. These features position the project as both a productivity tool and a highly customizable browser rather than a direct visual copy of another product.

Apple integration and browser-engine choices

Spaces, tabs and folders can synchronize through iCloud across supported devices. On Mac, Crest includes an import process that lets users review each Space before content is moved. The project says the importer does not retain the imported information. Optional Face ID or Touch ID locking is available, depending on the device.

Under the surface, Crest says it works with Chromium and WebKit and supports Chrome extensions. That combination is intended to preserve access to familiar web tools while presenting them through Crest's alternative navigation model. The project does not yet describe itself as a finished general-release browser, so prospective users should treat its current feature set as early-access software that may continue to change.

The project's own disclosure also says Crest's security has not been independently audited. That caveat matters for any browser, which routinely handles account sessions, saved data and sensitive web activity. Early adopters therefore have a clear reason to weigh the interface benefits against the maturity and external review of the software.

For people evaluating the software, the early-access label means compatibility and workflow choices should be tested against everyday requirements before Crest becomes a primary browser. Extension support, synchronization and device locking cover several common needs, but the product page does not replace independent assessment of stability or security.

Crest's launch illustrates how Arc's interface concepts are spreading beyond their original home. Its proposition is focused: bring Spaces, sidebar navigation and quick page views to an independent, open-source browser designed natively for Apple's main computing platforms.
