Runnable example apps for Toggly — feature flags, progressive delivery, and experiments across popular frameworks.
Official sample applications that show how to integrate Toggly SDKs in real apps. Each folder is a standalone project with its own README and setup steps.
- Create a free app at toggly.io (Always Free plan available).
- Pick a sample from the catalog below.
- Follow that sample's README (env keys, feature flags, and run commands).
SDK install guides live in docs.toggly.io and in the SDK monorepo.

New to feature flags? Start with a sample's first-toggle exercise, then its source-reading map. Follow configuration → initialization → one flag check → enabled/disabled branches before adding identity, Order context and filters. The JavaScript sample gives a browser-focused introduction; Next.js compares server and browser execution; Fastify shows request evaluation without a UI SDK. Sample fixtures and placeholder-key checks are not evidence of live Toggly app provisioning. Use each README's configuration recipe for your own application.
All new samples follow the Sample Contract and the shared flag and app template. Follow the application setup guide for dashboard controls and the management API procedure when a filter type is missing from the picker.
