Foff is a feature flag and configuration management service that gives your team fine-grained control over what features are enabled — and for whom. With Foff, you create flags once and resolve the right value automatically based on any hierarchy you define, from organization down to individual user.

Quick Start

Create your first feature flag and integrate it into your app in minutes.

Core Concepts

Learn about workspaces, scopes, features, and hierarchical overrides.

SDK Reference

Integrate Foff with TypeScript, Python, or Go using our official SDKs.

API Keys

Generate and manage API keys to authenticate your SDK and API calls.

How Foff works

1

Create a workspace

Sign up and set up a workspace for your organization. All your feature flags and configs live here.
2

Define a scope

A scope represents the hierarchy your flags follow — for example, Company → Department → Team → User.
3

Create feature flags

Add features with default values and optional overrides for specific hierarchy levels.
4

Integrate an SDK

Install the SDK for your language and call getFeatureConfig to resolve the right value at runtime.
