## What it is
Flagsmith is an open-source feature flagging and remote configuration service that lets teams toggle features on and off, segment users, and run A/B and multivariate tests without redeploying code. It can be self-hosted via Docker or used as a hosted cloud service, with SDKs for 15+ languages and integrations with analytics and observability tools.

## Use cases
- manage feature flags across web, mobile, and server-side apps
- roll out features gradually to a subset of users
- run A/B and multivariate tests on new features
- toggle features remotely without deploying new code
- self-host a feature flag service on-premise
- release features to beta testers and collect feedback
- manage remote app configuration from a dashboard
- govern AI feature releases with progressive delivery

## When to choose
- you need an open-source, self-hostable feature flag platform with a hosted option
- you want granular user segmentation and multivariate A/B/n testing
- you need SDKs across many languages and OpenFeature compatibility
- you want integrations with analytics, observability, and CI tools like Segment, Sentry, or Terraform

## When to avoid
- you only need simple boolean toggles and prefer a minimal in-code solution
- you want a fully free managed service without usage-based API limits
- your stack requires a vendor not covered by Flagsmith's SDKs or integrations
