Supaship

Supaship is a developer-first feature flag platform that enables safe releases, gradual rollouts, and instant user targeting with real-time updates and a global edge network.

What is Supaship?

Supaship is a feature flag management platform designed for development teams to control feature releases with precision. It takes feature flags—boolean toggles or more complex configurations—as input and provides capabilities for gradual rollouts, user targeting, and instant rollbacks. The platform runs on a global edge network, ensuring sub-50ms response times, and is available as a freemium service with no credit card required for the free tier.

Key Features

• Real-time feature flags — Update flags instantly across all environments without redeploying; changes propagate in under 50 milliseconds via the global edge network.
• Percentage rollouts — Gradually ramp up feature exposure from 0% to 100% of users, with precise control over traffic splits.
• Advanced user targeting — Target flags based on user attributes (e.g., location, subscription tier, custom properties) for segmented rollouts or A/B tests.
• Multi-language SDK support — Integrate with applications using any major language; SDKs available for JavaScript, Python, Ruby, Go, Java, and more.
• Performance analytics — Monitor flag evaluation metrics and dashboard latency to track the impact on application performance.
• Instant feature rollback — Disable any flag immediately to revert a problematic release, with full audit logging.
• Global edge network — Flag evaluations happen at edge nodes worldwide, achieving under 50 ms response times regardless of user location.
• 99.99% uptime SLA — Enterprise-grade reliability with a guaranteed uptime of 99.99%.

Who is it for?

• Development teams — Use feature flags to implement continuous delivery and trunk-based development, reducing merge conflicts and enabling decoupled deployments.
• Product managers — Control feature rollouts to specific user segments and gradually release new capabilities while monitoring user behavior.
• DevOps engineers — Manage production releases with automated rollback capabilities and canary deployments, minimizing risk of outages.
• Startups — Iterate quickly with safe feature releases using the free forever plan, scaling to enterprise needs as the company grows.

What can you do with Supaship?

• Safe deployment of new features — Roll out a new checkout flow to 10% of users, monitor error rates and conversion, then ramp to 100% if stable.
• A/B testing — Target two different UI variants to defined user segments and track performance analytics to determine the winner.
• Gradual rollouts to specific segments — Release a premium feature only to paying customers in a specific region, then expand globally over time.
• Instant kill switch — Disable a misbehaving feature across all users with a single toggle change, avoiding a full redeploy.

How does Supaship work?

Integrate the Supaship SDK into your application (available for multiple languages), define flags in the Supaship dashboard, and set targeting rules or rollout percentages. The SDK caches flag evaluations and syncs via the edge network, ensuring low-latency reads even during high traffic. When you change a flag in the dashboard, the update propagates to all edge nodes within seconds, and the SDK picks up the new value on the next evaluation.

Pricing

Supaship operates on a freemium model with a free forever plan that includes basic feature flagging and limited monthly active flags. Paid plans unlock advanced targeting, higher API limits, and priority support.
