ConfigCat is a feature flag platform with flat-tier pricing, unlimited seats and MAUs, and open-source SDKs. Free plan available; paid plans from $110/month.
ConfigCat is a Budapest, Hungary-based feature flag and remote configuration platform founded in 2018 by Zoltán, Gergely Sinka, and Lajos Szőke. The company was bootstrapped without venture funding, struggled through a slow first year, and grew largely through word of mouth after being listed as a LaunchDarkly alternative on AlternativeTo.net, eventually landing customers including Microsoft and H&M.
The platform lets engineering teams toggle features, run controlled rollouts, and manage remote configuration values without redeploying an application, and it holds SOC 2 Type II certification.
ConfigCat supports feature flags, percentage-based rollouts, audience segments, targeting rules, webhooks, and audit logs, all accessible through a dashboard or REST API. Its SDKs — covering JavaScript, Python, Go, Java, .NET, iOS, Android, and Node.js, among others — are open source.
The platform's defining feature is its pricing structure: unlike most feature flag competitors, ConfigCat does not charge per seat or per monthly active user, instead billing based on CDN configuration-download volume and network traffic, with unlimited team members and end users on every plan.
ConfigCat offers a Forever Free plan (10 feature flags, 5 million downloads per month, no card required) plus four paid tiers: Pro at $110/month, Smart at $325/month, Enterprise at $900/month, and Dedicated at $4,500/month, each scaling primarily by config-download volume, network traffic, and audit-log retention rather than by team size.
All plans, including the free tier, include unlimited seats, unlimited monthly active users, and API access, which differentiates ConfigCat's pricing model from per-seat competitors like LaunchDarkly.
