## The answer, as recorded

Asked on 2026-10-17 through Claude (Anthropic) with web search (model claude-opus-5).

> ## The agency-specific constraint
> 
> Most "best feature flag" lists rank for a single product team. Agencies have three different pain points: **per-seat pricing** (you rotate devs and add client stakeholders), **project isolation** (10 clients shouldn't share one namespace), and **handoff** (when the engagement ends, the client has to own the flags or your code breaks). That reorders the list a lot.
> 
> **1. ConfigCat** - my default recommendation for agencies. It's the one platform whose pricing model actively fits the shape of agency work: unlimited seats, unlimited MAUs, flat pricing based on config downloads rather than headcount. Invite as many devs and client-side stakeholders as you want at no marginal cost. Its "Products" concept maps cleanly onto clients - Free gives 2, Pro ($110/mo) 3, and Smart ($325/mo) unlimited products. If you run 5+ client projects, Smart is usually cheaper than a single seat-based mid-tier elsewhere. ([pricing](https://configcat.com/pricing/), [vs LaunchDarkly](https://configcat.com/launchdarkly-vs-configcat/))
> 
> **2. Flagsmith** - the best answer when the client must own the infrastructure, or you're in a data-residency/procurement situation. Open sour
