Overview
Override LaunchDarkly client-side feature flags in the browser.
**Override LaunchDarkly feature flags right in your browser — no server changes, no redeploys.** FlagSwap is built for QA engineers and developers who need to test features in specific on/off states. It intercepts the LaunchDarkly client-side SDK on your app's pages and serves the flag values you choose, so you control what's enabled without touching flag configuration in LaunchDarkly. **Features** - Toggle individual feature flags on or off instantly - Save named groups of flags and flip a whole set with one switch - Per-domain and per-subdomain profiles — overrides follow you automatically as you move between localhost, staging, and production - Optional sync: pull your real flag keys from the LaunchDarkly REST API using your own API token - Side panel to keep flag controls open next to your app while testing **Your data stays local.** All configuration and any API token you provide are stored in your browser. FlagSwap collects nothing, transmits nothing, and sells nothing.
