V2.0 is Live: Introducing Edge Synchronization

Ship code silently.
Release when ready.

Decouple deployment from release. ShipSilently is the enterprise feature management platform that lets teams test in production, mitigate risk, and control rollouts with zero latency.

// Initialize once

import ShipSilently from 'shipsilently'

const client = new ShipSilently({

apiKey: process.env.SHIPSILENTLY_KEY

})

// Evaluate a flag — <1ms at the edge

const enabled = await client.evaluate('new-checkout', {

userId: user.id,

plan: 'pro'

})

if (enabled) {

// show new experience

}

Control your surface area

Replace high-stress release nights with precise, targeted rollouts. ShipSilently provides the infrastructure to experiment safely at scale.

Targeted Rollouts

Expose features to specific user segments, internal teams, or geographical regions based on custom attributes before a global launch.

Instant Kill Switches

Detect an anomaly? Revert changes in milliseconds across your entire global infrastructure without rolling back or redeploying code.

Telemetry & Insights

Integrate natively with Datadog, New Relic, and Sentry. See exactly how flag changes impact your application's error rates and latency.

Engineered for developers.
Evaluated at the edge.

We built ShipSilently to feel invisible. With robust SDKs for every major language, you can integrate feature flags in minutes, backed by an architecture that guarantees sub-millisecond evaluation times.

Type-safe by default
Generated types ensure you never misspell a flag key again.
Local evaluation
Rules are cached locally. No network calls block your critical rendering path.

import { initialize } from 'shipsilently';

// Initialize the edge client
const client = initialize(process.env.SHIP_API_KEY);

async function handleCheckout(user) {
  // Evaluate flag with 0 latency
  const showNewGateway = await client.getFlag(
    'stripe-v2-migration',
    { userId: user.id, region: user.region }
  );

  if (showNewGateway) {
    return processStripeV2(user);
  }

  return processLegacyGateway(user);
