What Is Flagsmith? Feature Flag Tool Overview & Pricing

Overview

Flagsmith is an open-source feature flag and remote configuration service available as a hosted cloud, private cloud or self-hosted deployment. Its pricing is published and request-based. The Free plan includes about 50,000 requests per month, 100,000 experiment users and one seat, with unlimited flags, environments and segments^[15]. Start-Up costs US$40 per month billed yearly (US$45 monthly) for about 1 million requests, 500,000 experiment users and three seats, adding A/B and multivariate testing and scheduled flags^[15].

Scale-Up costs US$250 per month yearly (US$300 monthly) for 5 million or more requests, 2 million or more experiment users and five seats, expandable to 20 at US$50 per seat per month on yearly billing, and adds SSO/SAML, governance features and priority support^[15]. Enterprise, with 20 or more seats and an SLA, is where on-premises and own-cloud self-hosting are offered^[15]. Overages are charged per request, for example US$7 per 100,000 requests on Start-Up after a grace period^[15]. Flagsmith offers discounts for open-source, not-for-profit and charity projects^[15]. Its strengths are deployment flexibility and low entry pricing; its experimentation analytics are less developed than in experimentation-first tools.
