Feature management

Feature Management is a front-end feature-flag rules engine. You define a flag, the variations it can serve, and rules that decide which variation each user gets — matched against the tracked context Foldspace already collects: user attributes, subscription attributes, and the page URL. Because targeting runs on tracked data, you can turn a feature on for a specific group, roll it out gradually, and test it before it ships.

Each flag has a Variant Key (for example, sdk_config_block_email) that your front end reads through the SDK to decide whether a feature is on. Flags are scoped to a Product and Environment (for example, Prod), and the whole flag can be toggled on or off.

Variations

Section titled “Variations”

A flag’s variations are the values it can serve. Pick a Type (for example, Boolean), then define each variation with a Name, Value, and optional Description — for example SDK config block email is ON = true and SDK config block email is OFF = false.

Default Variations set what’s served when no rule matches:

  • Status OFF — the variation served when the flag is disabled.
  • Status ON — the variation served when the flag is enabled.

Rules

Section titled “Rules”

Under Segments, you build the rules that override the default for a targeted set. Each rule is one or more conditions on tracked context, combined with AND / OR:

Users · Email · Ends With · @foldspace.ai

Target on user, subscription, or page URL attributes. Then set On match serve:

  • Variations — serve one specific variation to everyone the rule matches.
  • Rollout — split matched traffic across variations by percentage (for example, 100% / 0%), so you can roll out gradually and widen over time.

Example rule

Section titled “Example rule”

Serve the “ON” variation to your internal team by matching users whose Email Ends With @foldspace.ai OR @eucera.ai OR @eucera.io, with On match serve → Variations → SDK config block email is ON. Switch On match serve to Rollout to ramp that same audience from a small percentage up to 100%.

Test before you ship

Section titled “Test before you ship”

The Test Feature tab evaluates the flag against data you pass in, so you can confirm which variation a given user, subscription, or page would receive before the rule goes live. History records changes to the flag, and Settings holds its configuration.
