- PostHogProduct analytics, flags, replay, and errors in one MIT-core stack
ee/ is a separate proprietary license. posthog-foss strips it if you need a clean MIT tree. Self-hosting is a Postgres + ClickHouse ops job. Cloud is usage-metered after the free allowances; replay is usually the line that bites first.
- UnleashAGPLv3 feature flags; OSS caps 1 project / 2 environments
Loud: OSS caps Projects 1 / Environments 2. Cloud = Enterprise trial FAIL — pitch self-host only. Vs PostHog dedicated-flags-inside-analytics. Distinct from PostHog.
- FlagsmithBSD-3-Clause flags; Cloud Free 50k req/mo, self-host uncapped
Cloud Free is capped (50k/1 seat/1 project); self-host uncapped. Vs PostHog analytics-native flags and Unleash AGPL OSS caps. Distinct from PostHog and Unleash.
- GrowthBookMIT-core flags+experiments; Cloud Starter Free, self-host unlimited users
Warehouse-native experimentation competitor to PostHog — different pitch (flags+experiments first). Cloud Starter Free has user/project caps; self-host OSS uncapped users. Distinct from PostHog.
