| Experiments | A built-in statistical engine, variant tracking, metric integrations, and auto-advance gradual rollouts are listed as coming in Q3 2026. | FeatBit describes feature-level A/B testing and an AI release decision agent that guides hypothesis, measurement, and continue, pause, or rollback decisions. |
| Integrations | Pluggable metric sources include Segment, Mixpanel, PostHog, and custom sources; Slack integration is listed as coming in Q3 2026. | The maker lists webhook integrations including Datadog, New Relic, Grafana, GrowthBook, and Slack, as well as OpenTelemetry integration. |
| Privacy | Backend SDKs send no evaluation context to feat, while browser SDKs report only hashed identifier-and-kind pairs for MAU counting. | FeatBit states it does not sell Customer Data or use it for advertising. |
| Product | feat is a hosted feature-flag platform for early engineering teams. | FeatBit describes itself as an open-source feature flag management platform for safer releases, experiments, and self-hosted delivery. |
| Rollouts | Sticky percentage rollouts keep the same user, device, or organization on the same variation across requests and sessions. | Feature flags support progressive rollouts, user targeting, instant rollback, and separating code deployment from feature release. |
| SDKs | First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart. | The maker lists SDKs for .NET, JavaScript, React, React Native, Node.js, Java, and Python, plus OpenFeature providers. |
| Security | Customer-facing endpoints use TLS 1.2+ and HSTS, with managed-service encryption at rest for Postgres, R2, and KV. | The Cloud security overview states that service traffic uses HTTPS/TLS, in-scope production storage uses cloud-provider encryption at rest, and privileged systems use MFA where supported. |
| Support | Free includes community support; Starter, Growth, and Scale list email response targets of 48 hours, 24 hours, and 8 hours respectively. | The maker lists Discord and GitHub community support for self-host plans, with paid-plan support options including email or tickets and enterprise shared channels. |

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.
FeatBit
FeatBit is an open-source feature-flag platform for controlling releases, experiments, and self-hosted delivery. Flags let teams separate code deployment from feature release, target users, roll changes out progressively, and roll back instantly. It supports feature-level A/B testing and describes an AI release decision agent for hypotheses, measurement, and continue, pause, or rollback choices. SDKs cover JavaScript and TypeScript, React, React Native, Node.js,.NET, Java, Python, Ruby, Go, Rust, and OpenFeature providers. Listed integrations include Datadog, New Relic, Grafana, GrowthBook, Slack, and OpenTelemetry. Self-hosting supports Docker Compose, a REST API, webhooks, and real-time WebSocket updates. FeatBit Cloud runs on Microsoft Azure. The Cloud Free plan allows 1,000 MAU; Foundation self-hosting is free without listed seat, MAU, project, or connection limits. Self-host Enterprise costs $3,999 a year.
