Setting up PostHog feature flags across platforms requires platform detection, SDK installation, flag creation, and environment configuration. This skill guides you through multi-language stack instrumentation for Web, Mobile, and backend environments to ensure robust gating.

Yes, you can gate new functionality with PostHog feature flags to enable safe rollouts and controlled releases. This allows you to enable a flag for a subset of users, validate impact, and coordinate gradual rollouts before a full release.

Yes, PostHog feature flag instrumentation supports both server-side and client-side evaluation. It provides platform-aware guidance across frameworks like React, Next.js, Node.js, Python, Java, Ruby, and Go for comprehensive gating control.

The best way to control feature rollouts using PostHog SDKs is to gate new or changed functionality behind flags. This workflow handles initial SDK setup and enforces frontmatter correctness to ensure safe experiments and documented releases across your app.

You need to instrument feature flags when implementing new features or reviewing PRs to ensure safe rollouts. This gating mechanism allows you to control releases, run experiments, and validate functionality for a subset of users before full deployment.

Resources folders and frontmatter are important for feature flag setup because they ensure a robust, documented workflow. Correct frontmatter enforces configuration validity, while optional resources folders provide necessary references and scripts for SDK setup and environment configuration.
