DEVELOPER WORKSPACE

Built for AI coding assistants and clean codebases.

FlagPilot integrates into your engineering flow. Manage flags in the visual dashboard, command line CLI, or inside LLM developer environments.

Dashboard

Manage feature flags visually. Configure rollout rules, targets, environments, webhooks, and team access in a premium developer dashboard.

CLI Tool

Create and manage feature flags directly from your terminal. Test keys, monitor evaluation streams, and script integrations using the official CLI.

AI Assistants

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.

OFFICIAL SDK REPOSITORIES

Integrate in under five minutes.

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.

ENGINEERING METRICS

High speed. Safe fallbacks.

We understand that feature flag logic must not slow down your app or disrupt user flows.

Local Evaluation

Evaluations execute purely in memory in sub-1ms. No blocking network requests or database lookups on client paths.

Sticky Rollouts

Deterministic SHA-256 calculation guarantees rollout stickiness. A user remains in their assigned cohort stably.

Instant Rollback

Kill malfunctioning features from the dashboard — connected clients pick up the change instantly over SSE.

Edge Sync

Flags replicate to edge locations worldwide, so evaluations always hit the server closest to your users.

BILLING PLANS

Simple pricing that matches your size.

Choose the tier that best matches your organization's feature flagging requirements.
