Where the request belongs

Work Feature Flag Rollout Calculator can move forward.

Built around the request

This is for the DevOps engineer who's tired of manual rollout math at 2am and the product manager who needs to know exactly how many users a new feature will hit before they hit 'go'.

01

DevOps Engineer

Validates that rollout percentages are hitting the right targets and checking for overlapping flags during deployment.

02

Product Manager

Plans the rollout schedule and ensures experiments have enough users to be statistically significant.

03

Software Engineer

Checks if a specific user ID is included in a feature group while debugging production issues.

Before you connect

Questions about Feature Flag Rollout Calculator.

The practical details behind the request, access and result.

How does the Feature Flag Rollout Calculator help with A/B testing?

It calculates the exact sample size you need to detect a regression. This ensures your results are statistically significant before you commit to a full launch.

Can I use the Feature Flag Rollout Calculator to check specific users?

Yes, you can ask your agent to verify if a specific user ID is included in a rollout. It uses consistent hashing to give you a definitive yes or no.

How do I know how many people will see a new feature?

You can ask the Connector to project the impact of different rollout stages. It will tell you the exact number of users affected at each percentage level.

Will the Feature Flag Rollout Calculator help prevent bugs from overlapping flags?

Yes, it estimates the intersection of multiple concurrent flags. This helps you identify if two features might be clashing for the same group of users.

Does the Feature Flag Rollout Calculator handle the actual toggling of flags?

No, this Connector handles the math and logic for rollouts. You still need your own system to store and toggle the flags themselves.

Why should I use this instead of a spreadsheet?

It's much faster and more accurate. It uses the same hashing logic your production system uses, so the numbers you see in your agent's chat are exactly what your users will experience.

How does the user assignment work?

The get_user_assignment capability uses consistent hashing of the User ID and Feature Key to ensure that a user's assignment remains deterministic at any given rollout percentage.

Can I use this for A/B testing?

Yes. You can use calculate_statistical_thresholds to determine the necessary sample size to detect a specific Minimum Detectable Effect (MDE) with your desired confidence level.

How do I estimate the impact of a multi-stage rollout?

Use project_rollout_impact by providing your total population size and a schedule of percentages to see both active and incremental user counts at each stage.
