## The Hook

Unleash is AGPLv3 feature flags you self-host when PostHog flags are bolted onto analytics.

## What's Good

AGPLv3. Dedicated feature-flag server. Self-host is the free path. SDKs across stacks. Open-source page is the pitch — not Cloud trial.

## The Catch

Loud: OSS caps Projects 1 / Environments 2. Cloud = Enterprise trial FAIL — pitch self-host only. Vs PostHog dedicated-flags-inside-analytics. Distinct from PostHog.

## Verdict

AGPLv3 flags. Self-host with OSS caps; Cloud trial is not free forever.
