Why switch from PostHog?

If you want a dedicated flag management workflow — audit history, CLI, MCP — without the rest of the analytics platform, or your pricing scales better with a flag-focused tool, FlagPilot may fit better.

Is FlagPilot cheaper?

Both offer free tiers. Compare based on whether you need PostHog's bundled analytics and replay features, or just feature flags.

Can I migrate existing flags?

Yes, by re-creating your flag keys and targeting rules in FlagPilot. There is no automated import tool from PostHog today, but the underlying concepts (rollout percentage, target users, kill switch) map directly.

Is there vendor lock-in?

No. Flag evaluation is a simple boolean check based on a flag key and a user ID — there's no proprietary data format to get locked into, and you can export your flag configuration at any time via the REST API.

Does FlagPilot support my language?

FlagPilot has published SDKs for JavaScript, Node.js, React, Next.js, Python, and Ruby, plus a REST API that works from any language capable of making HTTPS requests.

Do I need a sales call?

No. You can create an account, install an SDK, and evaluate your first flag without talking to anyone.

FlagPilot is currently available as a fully managed SaaS. You get evaluations, webhooks, and audit history without running any infrastructure yourself.

How long does migration take?

For a handful of flags, most teams re-create their flag keys and swap the SDK in under an hour. Larger flag inventories take longer mainly because of testing, not because migrating from PostHog itself is complex.

Why FlagPilot exists

Most feature flag platforms were designed for enterprise engineering organizations — built around governance workflows, approval chains, and permission structures that assume dozens of teams sharing one flag system.

FlagPilot was built for startups, solo developers, and small teams that simply want to release features safely. No complicated governance. No lengthy onboarding. No sales process.

Just create a flag and ship.

Why consider FlagPilot

A dashboard built around flags first, not flags as one tab in an analytics suite

Pricing tied to flag evaluations, not bundled analytics event volume

Manage flags from a CLI or an AI coding assistant

Get warned about flags that haven't been evaluated recently, before they pile up

import { FlagPilot } from '@flagpilot/javascript';

const client = new FlagPilot({

await client.initialize();

const isEnabled = client.evaluate('new-landing-page', {

Any programming language can fetch and evaluate flags via HTTP using our standard REST API.

What you get

Kill Switches

Disable a buggy feature instantly without redeploying.

Percentage Rollouts

Release to 5% of users before rolling out globally.

User Targeting

Beta test with selected customers before launch.

Feature Flags

Merge and ship code continuously, then turn features on when you're ready.

Instant Updates

Change a flag from the dashboard and connected apps pick it up without a deploy.

Migrating from PostHog Feature Flags

The evaluation model, rollout concepts, and targeting rules are similar enough that most teams change very little application code.

# Install the SDK
Add the FlagPilot SDK for your language alongside your existing PostHog SDK — no need to remove anything yet.

# Replace initialization
Swap the client constructor for FlagPilot's, using your project's API key. The evaluate() call shape stays conceptually the same.

# Re-create your flags
Create matching flag keys in FlagPilot's dashboard, REST API, or CLI. There is no automated import from PostHog today.

# Deploy and verify
Ship the change behind your existing flag keys, confirm evaluations show up in the dashboard, then remove the old SDK.

✓ Done — you're live on FlagPilot

Flag hygiene

Creating flags is only half the problem

Every feature flag you create is a small piece of technical debt until it's removed. Most platforms help you create flags. FlagPilot also helps you find the ones you forgot about.

Evaluation tracking

Every flag records when it was first and last evaluated, so you can see which ones are actually being used in production.

Stale flag detection

Flags that haven't been evaluated recently, or have been stuck at 100%/0% for a long time, are automatically surfaced for review.

Technical debt prevention

Catch forgotten flags before they turn into "why is this still here six months later" bugs.

AI-assisted cleanup

Ask an MCP-connected AI assistant to list stale flags or find flags that no longer appear in your codebase.
