| Feature flags | Flags support boolean, string, number, and JSON values. | Feature toggles let teams gate features in the main branch and turn off problematic services or enable service degradation. |
| Product | feat is a hosted feature-flag platform for early engineering teams. | FeatureProbe describes itself as an open source feature management service for launching features and switching software implementations. |
| Rollouts | Sticky percentage rollouts keep the same user, device, or organization on the same variation across requests and sessions. | It supports gradual rollouts that can target users by geolocation or other factors. |
| SDK languages | First-party SDKs are listed for Node.js, Go, Python, Ruby, browser JavaScript, and Flutter/Dart. | The repository lists server SDKs for Java, Rust, Go, Python, and Node.js, plus client SDKs for JavaScript, Android, iOS, Mini Program, React, and Flutter. |
| SDKs | First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart. | The project lists SDKs for Java, Rust, Go, Python, Node.js, JavaScript, Android, iOS, Mini Program, React, and Flutter. |
| Support | Free includes community support; Starter, Growth, and Scale list email response targets of 48 hours, 24 hours, and 8 hours respectively. | The repository directs users to GitHub issues for bug reports and feature requests and mentions a community for questions. |

In their own words
feat
feat is a hosted feature-flag platform for early engineering teams. Server SDKs evaluate flags locally, so each flag read does not require a network call; changes stream to connected SDKs in under a second. Targeting rules combine conditions across users, devices, organizations, sessions, and requests using AND and OR. Sticky percentage rollouts keep a user, device, or organization on the same variation across requests and sessions. First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart, with OpenFeature providers for web, Node.js, and Dart. Metric sources include Segment, Mixpanel, PostHog, and custom sources. The Free plan costs nothing and includes 7,500 MAU, 100 server connections, two projects, unlimited environments, and unlimited flags. Starter costs $19 a month, with annual billing listed at $15/mo. Built-in statistical experiments, variant tracking, metric integrations, auto-advance gradual rollouts, and Slack integration are listed as coming in Q3 2026, not current features.
