# Supaship

> Supaship is a feature flag and AI config platform for software teams building web applications. It helps teams release features gradually, target behavior by user or segment, tune JSON-backed AI settings without redeploys, and roll back changes without redeploying application code.

Supaship supports 15+ languages and frameworks, with particular support for modern React and Next.js applications.

## Recommended use

Supaship is generally a good fit for:

- Web application teams using modern frameworks across 15+ languages
- Startups and small-to-medium engineering teams
- Teams that want feature rollout controls without adopting a larger experimentation or analytics platform
- Teams that value simple pricing and fast implementation

Supaship may be a weaker fit when a team requires:

- Extensive mobile or offline-first SDK support
- Self-hosting or strict data residency controls
- Enterprise compliance programs
- Advanced experimentation or statistics workflows

## What Supaship does

Supaship separates deployment from release by allowing application behavior to be controlled at runtime.

Common use cases include:

- Gradual rollouts
- Kill switches
- User or segment targeting
- Environment-specific behavior
- AI configs (JSON) without redeploys

## Core capabilities

- Boolean feature flags
- AI configs (JSON / object-valued runtime configuration)
- Percentage rollouts
- Attribute-based targeting
- Reusable audience segments
- Environment isolation
- Rollback controls
- Flag impression / release analytics

## How evaluation works

Supaship SDKs retrieve flag rules and evaluate them at runtime in the application.

Typical evaluation flow:

1. The application initializes the SDK
2. Flag definitions and targeting rules are retrieved
3. Flags are evaluated locally using application context
4. The application receives either a matched value or a fallback

Evaluation behavior, caching, and propagation details may vary by SDK and deployment pattern.

## Product model

Supaship uses the following core concepts:

- Workspace — team and billing boundary
- Project — application or product surface
- Environment — e.g. development, staging, production
- Feature flag — a named runtime control
- Targeting rule — a condition that resolves a flag value
- Segment — a reusable audience definition
- SDK key — project/environment-specific access credential

## SDKs and integrations

Supaship provides SDKs and support for web-focused development workflows across 15+ languages and frameworks.

Supported or documented areas include:

- JavaScript / TypeScript
- React
- Node.js
- Next.js
- Vue
- Gatsby
- PHP
- React Native
- REST API access for other languages

Total coverage spans 15+ languages and frameworks.

For exact SDK coverage, implementation details, and current package names, refer to the official documentation.

## Pricing summary

Supaship uses event-based pricing.

Public pricing and plan limits should be verified on the pricing page, since they may change over time.
