| Spec score · Feature Flag Software | 9.3 (#2) | 8.7 (#8) |
| Feature flags | Flags support boolean, string, number, and JSON values. | Flags belong to projects and can have different activation strategies in each environment. |
| Headquarters | India | Oslo, Norway |
| Integrations | Pluggable metric sources include Segment, Mixpanel, PostHog, and custom sources; Slack integration is listed as coming in Q3 2026. | Official integrations include Datadog, Jira Cloud, Microsoft Teams, ServiceNow, Slack and generic webhooks; community integrations include Fastify, Quarkus, Vue and New Relic. |
| Progressive rollouts | Progressive rollouts can automatically advance through scheduled percentage steps. | Built-in strategies can expose a feature gradually by percentage, user, segment, IP, hostname or other context. |
| SDKs | First-party SDKs are available for Node.js, Bun, Deno, Go, Python, Ruby, browser JavaScript, and Flutter/Dart. | Unleash lists 25+ SDKs for languages and frameworks including Node.js, Java, Go, Python, .NET, React, Android, and iOS. |
| Security | Customer-facing endpoints use TLS 1.2+ and HSTS, with managed-service encryption at rest for Postgres, R2, and KV. | The pricing page lists SOC 2 Type II and GDPR compliance, SSO via SAML 2.0 or OpenID Connect, role-based access control, and audit log retention of up to two years. |
| Security controls | feat states that customer-facing endpoints use TLS 1.2 or newer, with HSTS and managed-service encryption at rest. | Unleash documents SAML 2.0 or OpenID Connect SSO, SCIM, RBAC, CORS and IP controls, four-eyes approvals, audit logging and SIEM integrations. |
| Support | Free includes community support; Starter, Growth, and Scale list email response targets of 48 hours, 24 hours, and 8 hours respectively. | Pay-As-You-Go includes standard support with a one-business-day response target; Custom Enterprise offers standard or premium support and severity-based response times. |
| What it does | feat is a hosted feature-flag platform for engineering and product teams. | Unleash controls feature releases at runtime so teams can deploy code separately from enabling functionality for users. |

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.
Unleash
Unleash is a feature management platform for controlling software behavior and releases in production without redeploying code. Teams can stage progressive rollouts, roll back instantly, apply release templates, and use kill switches. Its experimentation tools include A/B/n testing, flag variants, user segmentation, and stickiness. Flags are evaluated in SDKs or at the edge rather than on the Unleash server. The service lists more than 25 SDKs, including options for Node.js, Java, Go, Python,.NET, React, Android, and iOS. Listed integrations include Slack, Teams, Datadog, Jira, webhooks, and Admin, Frontend, and Client APIs. The free Open Source instance allows no seat limit but is restricted to one project, two environments, and 5,000 flags; it lacks SSO, SCIM, granular RBAC, change-request approvals, and a support SLA. Pay-As-You-Go costs $75 a month, billed monthly, and has a 14-day trial without a credit card. Enterprise can be hosted, self-hosted, or hybrid, with US or EU data residency available.
