Ship features behind a flag, manage them with a single prompt to your AI coding assistant, and never let a forgotten flag turn into a bug six months from now.
Free forever for personal projects. No credit card required.
Specify the percentage of traffic that evaluates to true. Evaluations use sticky hashing based on user IDs.
Give specific users early access before gradually rolling out the feature to everyone.

FlagPilot integrates into your engineering flow. Manage flags in the visual dashboard, command line CLI, or inside LLM developer environments.
Manage feature flags visually. Configure rollout rules, targets, environments, webhooks, and team access in a premium developer dashboard.
Create and manage feature flags directly from your terminal. Test keys, monitor evaluation streams, and script integrations using the official CLI.
Manage feature flags using Cursor, Claude Code, or any MCP-compatible client. Leverage the official MCP server to declare and check flags directly from AI prompts.
import { FlagPilot } from '@flagpilot/javascript';
const client = new FlagPilot({
clientKey: 'fk_client_xxxxxxxx',
environment: 'production'
});
await client.initialize();
const isEnabled = client.evaluate('new-landing-page', {
userId: 'usr_visitor_123'
});
if (isEnabled) {
showNewFeatures();
}Any programming language can fetch and evaluate flags via HTTP using our standard REST API.
We understand that feature flag logic must not slow down your app or disrupt user flows.
Evaluations execute purely in memory in sub-1ms. No blocking network requests or database lookups on client paths.
Deterministic SHA-256 calculation guarantees rollout stickiness. A user remains in their assigned cohort stably.
Kill malfunctioning features from the dashboard — connected clients pick up the change instantly over SSE.
Flags replicate to edge locations worldwide, so evaluations always hit the server closest to your users.
Choose the tier that best matches your organization's feature flagging requirements.
For side projects and getting started.
For single developers building production apps.
For startup teams requiring collaboration.
For enterprise feature flag scaling.
