## The answer, as recorded

Asked on 2026-09-24 through Claude (Anthropic) with web search (model claude-opus-5).

> For an agency the ranking is different than for a product team - what matters is many separate client projects, rotating contractors on the dashboard, and being able to hand the whole thing over when the engagement ends. That pushes against per-seat and per-MAU pricing.
> 
> **1. ConfigCat** - my default recommendation for agencies. Unlimited seats on every paid plan and unlimited projects, so adding a client's PM or a freelance dev costs nothing, and each client gets its own project with isolated SDK keys per environment. Pricing is by config fetches, which scales with actual usage rather than headcount. The catch: the free tier caps you at two environments, so you'll be on a paid plan quickly with real clients.

> 
> **2. Flagsmith** - the best pick when you need to hand the instance to the client at the end of the project. Core flagging, targeting, multivariate and remote config are BSD-3-Clause and self-hostable with no user restrictions, so you can run it on the client's own infra and walk away without leaving them a subscription they didn't ask f

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.
