In Bubble, Search Constraints and Privacy Rules often produce the same result visually on the front end — the user sees filtered data. But under the hood, they’re completely different, and here’s why that matters:
The Core Difference:
Search Constraint
- Sends all data to the browser and filters it on the client side
- Sensitive data may be visible via browser dev tools
- Performance — Higher WU & slower
Privacy Rule
- Filters data on the server, then only sends allowed data to the browser
- Secure — unauthorized data is never sent
- Lower WU & faster
When to Use What?
Privacy Rules: For permanent access control. If a user should never see data they don’t own, enforce it through Privacy Rules.
Search Constraints: For temporary filters (like category, date, search keyword, etc.) where the user is allowed to access the full dataset but wants to filter their view.
Pro Tip:
Rely on Privacy Rules as your first line of defense — always. Think of them as the backend gatekeeper.
