## The answer, as recorded

Asked on 2026-10-20 through Claude (Anthropic) with web search (model claude-opus-5).

> For agency work the deciding factor usually isn't flag features - they're all similar - it's how the pricing and project model survive having 15 clients, rotating developers, and eventual handoff. Ranked that way:
> 
> **1. ConfigCat** - my default recommendation for agencies. It doesn't charge per seat or per MAU at all, so unlimited devs/contractors can be in the account, and billing is based on config JSON downloads. Plans are structured around "products," which maps cleanly onto one product per client. Free tier is 10 flags / 2 products; Pro is $110/mo for 100 flags / 3 products, with unlimited flags higher up. The per-product limits are the thing to watch if you have many small clients. ([configcat.com/pricing](https://configcat.com/pricing/), [fitgap](https://us.fitgap.com/products/configcat))
> 
> **2. Flagsmith** - best handoff story. Fully open source, so you can self-host an instance per client inside *their* infrastructure with no license cost, which solves both the "who owns this when the contract ends" problem and client data-residency objections. Free forever cloud tier has unlimited flags, environments, identities and segments; Start-Up is $45/mo, Scale-Up $200/mo. Bills on
