Air Traffic Control

Create save routes to file links into spaces, and open routes to control which browser opens them - like mail rules for your bookmarks.

How It Works

Air Traffic Control has two types of routes:

Save Routes - When you save a page (⌘⌃S), save routes are checked. The first matching route files the link into the specified space. Save routes can also filter by which browser you’re saving from.
Open Routes - When you click a link in the sidebar, open routes are checked. The first matching route opens it in the specified browser instead of your default.

Rules are evaluated top-to-bottom. The first matching rule wins. If no rules match, the link uses your current space and default browser.

Explicit choices always override ATC. If you use Opt-click or the browser picker to choose a specific browser, that choice takes priority over any routing rule.

Setup

Open Preferences → Air Traffic Control
Toggle Enable Air Traffic Control
Click Add Route to create your first rule

Creating a Rule

When you click Add Route, you first choose the route type:

Save Route

Routes saved links to a specific space.

Setting	Description
Source Browser	Only match when saving from this browser, or “Any Browser” (optional)
URL Pattern	The text to match against link URLs (optional if source browser is set)
Match Type	`contains`: URL includes the pattern anywhere. `is equal to`: URL must match exactly
Save to Space	The space to file matching links into

Open Route

Opens matching links in a specific browser.

Setting	Description
URL Pattern	The text to match against link URLs
Match Type	`contains`: URL includes the pattern anywhere. `is equal to`: URL must match exactly
Open in Browser	The browser to open matching links in

A live preview at the bottom of the editor shows exactly what the rule will do as you configure it.

Managing Rules

Reorder - Drag rules to change priority (first match wins)
Enable/Disable - Toggle individual rules without deleting them
Edit - Click a rule to modify its settings
Delete - Remove rules you no longer need

Examples

Save Routes

Source Browser	URL Pattern	Save to Space	Effect
Any	`github.com`	Development	All GitHub links go to Dev space
Firefox	(empty)	Work	All tabs saved from Firefox go to Work space
Safari	`banking.`	Finance	Banking URLs saved from Safari go to Finance space
Any	`docs.google.com`	Work	Google Docs go to Work space

Open Routes

URL Pattern	Open in Browser	Effect
`figma.com`	Chrome	Figma links always open in Chrome
`localhost`	Safari	Local dev URLs open in Safari
`github.com`	Chrome	GitHub links open in Chrome

Combining Both

Want GitHub links to go to your Dev space and always open in Chrome? Create two rules:

Save Route: github.com → Development space
Open Route: github.com → Chrome

Each rule does one thing clearly - no ambiguity.

Tips

Start broad, refine later - Begin with domain-level patterns like github.com, then add specific patterns if needed
Use “contains” for most rules - It’s more flexible than exact matching
Order matters - Put more specific rules above general ones
Source browser filters are powerful - Use them to keep different browsers organized into separate spaces automatically
Combine with Spaces - ATC is most useful when you have multiple spaces for different contexts
