Astral vs Arc:
The Agentic Alternative to the Arc Browser

Arc is genuinely beautiful. The Browser Company set a new standard for what a browser could look and feel like — Spaces, Easels, Little Arc, command bar. It is the most thoughtful browser UX in years, and we mean that sincerely.

Astral is the next step that Arc's philosophy points toward: what if you did not need to browse at all? An AI agent accesses your data as structured JSON through the open UADP protocol, signs requests with your passkey, and presents results in a conversational interface you configure by voice. No tabs. No URLs. No browsing.

Cloud-synced via The Browser Company servers
Data access model
✓ Structured JSON via open UADP protocol with scraping fallback
Standard HTTP / HTML rendering with JS execution
Cross-service workflows
✓ Native — agent orchestrates email, banking, shopping in one request
Manual — user opens tabs across services
Open protocol
✓ Yes — UADP is an open spec anyone can implement
No open protocol; proprietary sync and AI layer

If you loved Arc, you will love Astral

Arc users tend to share a certain disposition: they want their computer to work intelligently, not just render pages. Astral takes that instinct to its logical conclusion.

You hate managing tabs

Arc's auto-archive was a step in the right direction. Astral removes the tab paradigm entirely — your agent brings the information to you.

You want AI to do more

Arc Max adds AI to a browser. Astral makes AI the browser. The difference is not cosmetic — it is architectural.

You care about privacy

If Arc's cloud sync ever felt like a compromise, Astral's local-first design and Secure Enclave-backed passkeys will feel like coming home.

Frequently asked questions

Is Astral a replacement for Arc?

Astral is not a direct replacement for Arc — it is the next step beyond Arc's vision. Arc reimagined how humans browse. Astral removes the browsing layer entirely: an AI agent fetches, filters, and presents your data through UADP so you never open a tab in the first place. If you loved Arc's philosophy, Astral is where that philosophy leads.

Can I run Astral alongside Arc?

Yes. Astral is a native Tauri 2 desktop application and runs happily alongside Arc, Chrome, or any other browser. Use Arc for interactive web pages and beautifully organised spaces; use Astral when you want your agent to handle a task without you opening a browser at all.

Does Astral have a visual browsing interface like Arc?

Astral has a UI — a conversational shell and structured data panels rendered by ComponentConfig — but it does not render arbitrary web pages. The interface is built for reading agent responses and managing services, not for traditional tab-based navigation.

What happens to Arc's Spaces and Easels in an agentic workflow?

Arc Spaces are a great way to organise open tabs. In Astral, you organise services and agent workflows instead of tabs. ComponentConfig lets your agent arrange panels, cards, and feeds — all driven by voice or text commands, persisted to your local profile, and synced across devices.
