## The answer, as recorded

Asked on 2026-09-15 through Claude (Anthropic) with web search (model claude-opus-5).

> Searched - here's the landscape as of now, framed for how agencies actually buy this (many small client projects, rotating staff, and eventual handover to the client).
> 
> ## What I'd actually recommend
> 
> **1. ConfigCat** - my default pick for agencies. Unlimited seats and unlimited MAU on *every* tier including free, so you never pay extra to add a junior dev for two weeks or give a client stakeholder read access. You're billed on "products" instead: Free gets 2 products/10 flags, Pro ~$110/mo gets 3 products/100 flags, Smart ~$325/mo gets 10 products. That maps cleanly onto "one product per client." The catch is that the product limit is the thing that bites you, so price it against your client count, not your headcount.

> 
> **2. Flagsmith** - best when clients have compliance or data-residency demands, or when you want to hand over a self-hosted instance at the end of the engagement. Open source with SaaS, private cloud, and on-prem options; paid tiers give unlimited projects, which is the right shape for agency work. Free tie

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
