## The answer, as recorded

Asked on 2026-10-04 through Claude (Anthropic) with web search (model claude-opus-5).

> Searched current pricing and comparisons. For agency work the deciding factors are different from in-house: you juggle many client projects, staff rotate on and off accounts, and you often need to hand the whole thing over to the client at the end. That makes per-seat pricing and per-project billing the main thing to avoid.
> 
> **1. ConfigCat** - my default recommendation for agencies. Unlimited seats with no per-user fee, and billing is on config fetches rather than MAU or seats, so adding a contractor or a client stakeholder to the dashboard costs nothing. Unlimited projects on the paid tiers ($110/mo Pro for 100 flags, $325/mo Smart for unlimited), which is roughly 75-90% cheaper than LaunchDarkly at agency headcount. Free tier (10 flags, unlimited members) is enough to pilot on a small client.
> 
> **2. PostHog** - best when clients want flags bundled with product analytics and A/B testing instead of a separate line item. 1M flag requests/month free on cloud, then transparent per-request pricing; self-hosted OSS is free. Very easy to justify on a client invoice because they get analytics out of the same spend.
> 
> **3. Unleash or Flagsmith, self-hosted** - the answer when a client insist
