How SwitchFlag Works

Deploy confidently in three steps.

1

Create Flag

Define your feature flag in the dashboard. Set default values for production.

2

Implement

Wrap your code with our type-safe SDK. It's just one line of code.

3

Target & Rollout

Enable for specific users, percentage rollouts, or your internal team only.

Platform Features

5ms Latency

Global edge network ensures your flags evaluate instantly, preventing content flash or layout shifts.

Type-Safe SDKs

Generated types based on your dashboard configuration. Catch missing flags at build time, not runtime.

Team Management

Granular permissions, audit logs, and environment scoping. Built for scaling engineering teams.

Instant Rollbacks

Kill switch functionality allows you to disable buggy features instantly without redeploying code.

A/B Testing

Run experiments on specific user segments. Analyze data and roll out the winning variant.

User Segmentation

Target flags based on email, region, subscription tier, or any custom attribute you define.
