Feature flags

Ship the code. Turn the feature on later.

Each flag has its own value per environment, with targeting rules, percentage rollouts and a kill switch. A change reaches every server in about a second, with no new deploy.

What you get

  • Four kinds of value

    Boolean, string, number or JSON. For features, experiment copy or settings.

  • Environments and branches

    Production, preview and development each have their own config, and a preview branch can have its own.

  • Targeting rules

    By email, plan or any attribute you pass: equals, contains, starts with, in a list and more. The first rule that matches wins.

  • Percentage rollouts

    Give a feature to a share of users. A user always gets the same answer, and raising the share only adds users.

  • Segments

    Make lists of users (staff, early testers, large customers) and use them in any flag's rules.

  • Kill switch

    Send a broken feature back to its off value everywhere with one click.

  • History and rollback

    Every change is kept with who made it. Go back to any version, even of a deleted flag.

  • env.FLAGS with no network call

    In functions and apps, flags are read from a local copy, not from a remote service.

  • Outside the platform

    A mobile app, a web page or another server reads flags with the standard OpenFeature SDKs and a flag key; a browser key sees only the flags marked visible to browsers.

  • Dashboard, CLI, API and MCP

    Create and change flags from any of them; they all call the same API.

A rule, a percentage, one line of code

Create the flag from the CLI and read it in code.

cloudhost flags add new-checkout --type boolean
cloudhost flags rule add new-checkout email ends_with @acme.ir --value true --environment production
cloudhost flags rollout new-checkout 10 --value true --environment production

Included in the plans

Flags come with every project. The number of flags, rules and segments depends on the plan; reads from outside the platform are counted as flag requests (100,000 a month free). See the pricing page.
