In their own words
Featureflow
Featureflow manages feature releases for engineering and product teams. It separates deployment from release: teams can deploy code silently, then enable features later without another deployment. Targeting rules can use individual users, cohorts, dates, times of day and custom attributes. Teams can roll features out by percentage or environment, organize users into segments and use instant kill switches. Release pipelines arrange ordered phases with environment mapping, default targeting and approval gates. Integrations include Slack, Jira, CI/CD webhooks, a REST API and AI assistants through MCP. SDKs are listed for a broad set of server and client technologies, including Java, Node.js, Python, React Native, iOS and Android. Feature flag and user data are encrypted at rest in a SOC II compliant data centre. The free plan supports five seats, one project, two environments and one million SDK requests monthly. Team is $99 a month; Business is $399 a month. Enterprise pricing is custom, and the service lists a 14-day trial.
Flagsmith
Flagsmith manages feature flags and remote configuration for web, mobile, and server-side applications. Teams can target releases by environment, individual user, segment, or percentage, and split users across variations for A/B and multivariate tests. Remote configuration lets teams change properties such as text, colors, and behavior without deploying new code. Deployment options include hosted cloud, private cloud, and self-hosted. Its listed integrations include Amplitude, Datadog, GitHub, GitLab, Grafana, Jira, Mixpanel, OpenFeature, Segment, Sentry, Slack, and Terraform; environment-level webhooks can send events to a team's infrastructure. The maker says core feature-flag functionality is open source and most of the product uses the BSD-3 licence. The Free plan includes 50,000 monthly requests and one team member; after exceeding the request limit, users have seven days to upgrade before action is taken. Paid plans start at $40 a month, billed 12 months paid up front. Platforms include Android, API, iOS, Linux, macOS, self-hosted, web, and Windows.
