# Edit text and feature flags without a deploy

> Edit a headline, swap a number, or flip a feature switch — live in seconds, no redeploy.

Update your app's text, numbers, and feature switches from the admin and see them change in the live app instantly.

Your agent hardcoded the headline. Also the phone number, the opening hours, and the banner you
only meant to run for a week. Now every tiny change means another prompt, another build, another
deploy — a full round-trip for a single word.

VibeKit gives your app a **Variables** tab instead: central values your app reads at runtime.
Change one in the admin and it updates in the live app instantly, with no redeploy.

## What goes in a variable

Strings, numbers, and booleans — a headline, a phone number, an on/off feature switch. Anything
you (or whoever runs the site after you) will want to change after launch belongs here rather
than baked into the code. Booleans double as feature flags: turn a section on for a launch and
off again when it ends, straight from the admin.

## Built for agent-built apps

Each variable has a stable reference your agent reads through the client. So instead of asking
your agent to bake the value in, you ask it to read the variable — and from then on, the admin is
where that value lives. Your agent can also subscribe to a variable, so a change you make in the
admin lands in pages that are already open, not just on the next load.

## A tiny CMS and a flag service in one

In practice it works like a tiny CMS plus a feature-flag service — except there's nothing to
sign up for or integrate, because it's already wired into your app. Each app keeps its own set of
variables, so nothing leaks between projects.

## Beyond text and switches

Your logo and colour theme get the same treatment with their own dedicated home — see
[instant branding](/products/vibekit/features/instant-branding). And when the thing that changes is the data
itself rather than your copy, [live data](/products/vibekit/features/live-data) pushes record updates onto the
page the same way: no refresh, no redeploy.
