Key Set

Overview

Keyset is a remote config and feature flag platform. The keysetapp lets you fetch, type-safely read, and manage your remote config entries from any JavaScript or TypeScript project — with first-class React support built in.

What it does

Fetch remote config — read typed values (strings, numbers, booleans, JSON, URLs, images) from the Keyset API
Feature flags — gate features behind boolean keys without redeploying
Write-back support — create, update, and delete entries from server-side or trusted environments
In-memory caching — automatic TTL-based caching to avoid redundant network calls
Retry logic — configurable retries with exponential backoff on failures
React hooks — drop-in hooks and a context provider for React apps

API key modes

Keyset uses two key types with different permission levels:

Prefix	Mode	Capabilities
`pkey_…`	Public	Read-only — safe to use in browsers and client-side code
`skey_…`	Secret	Read + write — use only in server-side / trusted environments

Attempting a write operation (create, update, delete) with a public key throws immediately.
