## The answer, as recorded

Asked on 2026-09-13 through Claude (Anthropic) with web search (model claude-opus-5).

> Assuming you mean a dev/product agency building on behalf of clients (not government agencies), here's what I'd actually recommend. The agency constraint that changes the answer is that seat counts churn (contractors in and out, client stakeholders wanting read access), you run many small projects instead of one big one, and every project eventually gets handed off.
> 
> **1. ConfigCat** - my default pick for agencies. Unlimited seats and unlimited MAU on *every* tier, including the free one; you pay by configs/products instead. That's the single biggest cost lever for an agency, because you can add a client's PM to a dashboard without it showing up on an invoice. Unlimited products at the Enterprise tier ($900/mo). ([configcat.com](https://configcat.com/blog/top-launchdarkly-alternatives/), [rollgate.io](https://rollgate.io/blog/feature-flags-pricing-comparison))
> 
> **2. Flagsmith** - open source with hosted, private-cloud, and self-hosted options, and a clean project/environment hierarchy that maps well to client separation. The self-host path matters for handoff: you can leave the client running their own instance instead of forcing them into a contract with your vendor. Free up to 2

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.
