Flagbearer vs PostHog feature flags
PostHog is an all-in-one product suite: analytics, session replay, experiments and feature flags in one place. Flagbearer is a feature flag tool and nothing else. Launch to a few people, grow to everyone, and adjust anytime without a redeploy.
Both are good choices. Which one fits depends on what you're looking for.
Why teams pick Flagbearer
- Flags are the whole product. Every screen is about creating a flag, rolling it out and seeing who has it. There's nothing else to configure first.
- Gradual rollouts built in. Start with your testers, then grow by percentage at whatever pace feels right. People who already have the feature keep it as the rollout grows.
- Live updates. A change reaches your users within seconds, in the browser, on mobile and on your servers.
- Pricing you can read. Plans are sold by monthly users, the people who actually see your flags, so the bill doesn't move with how often your code checks a flag. The prices are on the pricing page.
- Made for agents and CI. Flip a flag from a terminal, a deploy job, or an AI agent like Claude Code, with the same access controls as the dashboard.
How the two compare
Scope. PostHog gives you a full analytics stack with flags as one part of it. Flagbearer gives you flags on their own, and works alongside whichever analytics tool you already use.
Pricing. PostHog publishes its current pricing on its own site. Flagbearer has a free plan for a single app, and every paid plan starts with a free trial.
Getting started. With Flagbearer you sign up, create a flag and check it in code. The docs fit on a page per platform.
When PostHog is the better fit
If you want product analytics, session replay and experiments from the same vendor as your flags, PostHog brings them together. If you already have analytics you like, or you just want flags that are quick to add and a pleasure to use, Flagbearer is built for you.
Using both
Plenty of teams keep PostHog for analytics and use Flagbearer for flags. The two don't overlap in your code: one records what people do, the other decides what they see.
