Feature flags you’ll enjoy using

Step up from homegrown or all-in-one tools to purpose-built feature management.

Accidentally ship invalid flags.

Type-safety with the CLI.

Tricky to test features locally.

Toggle features with our toolbar.

Breaking flow just to flag a new feature.

Create flags from your editor with MCP.

Works with most modern code editors and LLM chat clients.

Flag cleanup on autopilot

Automated archiving of stale flags, removing obsolete code before it becomes tech debt.‍

AI identifies unused flags and creates PRs in GitHub for you.

A workflow to build with your users

An alternative to A/B experiments for those who favor taste over tests.

Test in prod, grant early-access, or run betas.

Monitor feature exposure and adoption.

Capture issues or requests in-app.

Discuss feedback in Slack or Linear.

Built for SaaS products

Work with companies as easily as users. No pasting lists of UUIDs needed.

Difficult to assign features to companies.

Automatic company aggregation.

Can’t limit feature access by subscription.

Filter companies by segments like plan.

Hard to see and edit the features a company can access.

List and toggle feature access from the company page.

Features, users, and feedback for a company, all together.

“We switched from LaunchDarkly to Bucket to get feature management that is opinionated and optimized for shipping.”
