What This Plugin Adds

Section titled “What This Plugin Adds”

Experiments is an Available, Schema-owning Capell package in the Capell Marketing & Growth product group. It ships as capell-app/experiments and extends these surfaces: admin, frontend.

Experiments adds server-side page and campaign tests with audience rules, weighted variant allocation, goal events, retention, and statistically gated winner reports.

Growth operators configure experiments, variants, goals, and eligible audiences in the admin, while consenting visitors receive an opaque allocation through private no-store endpoints.

Status details:

  • Status: Available
  • Tier: premium
  • Bundle: marketing-growth
  • Composer package: capell-app/experiments
  • Namespace: Capell\Experiments
  • Theme key: not applicable

Why It Matters

Section titled “Why It Matters”

For developers: Typed context and result data pass through focused Actions for audience evaluation, allocation, conversion recording, and winner calculation.

For teams: Teams can control who enters a test, compare goal performance, and wait for the configured evidence threshold before declaring a winner.

Data Model

Section titled “Data Model”
  • Required tables: experiments, experiment_variants, experiment_goals, experiment_audience_rules, experiment_allocations, experiment_goal_events.
  • Models: Experiment, ExperimentAllocation, ExperimentAudienceRule, ExperimentGoal, ExperimentGoalEvent, ExperimentVariant.
  • Core record references in migrations: sites via site_id.
  • Migration files: 2026_05_31_000001_create_experiments_table.php, 2026_05_31_000002_create_experiment_variants_table.php, 2026_05_31_000003_create_experiment_goals_table.php, 2026_05_31_000004_create_experiment_audience_rules_table.php, 2026_05_31_000005_create_experiment_allocations_table.php, 2026_05_31_000006_create_experiment_goal_events_table.php, 2026_06_07_000001_add_idempotency_unique_to_experiment_goal_events_table.php, 2026_10_04_000001_remove_implicit_timestamp_updates_from_experiments.php.
  • Migration impact: run host migrations through the package install flow before opening package surfaces.
  • Deletion/retention behaviour: migrations declare cascade-on-delete relationships and null-on-delete relationships; retention is scheduled through capell:experiments:prune (daily; registered by the package provider).

Install Impact

Section titled “Install Impact”
  • Required packages: capell-app/admin, capell-app/core.
  • Admin navigation: declares admin-resource: ExperimentAudienceRuleResourceContribution, admin-resource: ExperimentGoalResourceContribution, admin-resource: ExperimentResourceContribution, admin-resource: ExperimentVariantResourceContribution; each Filament page or resource controls its own navigation visibility.
  • Admin/editor extensions: none declared.
  • Permissions: View:Experiment, Create:Experiment, Update:Experiment, Delete:Experiment, View:ExperimentVariant, Create:ExperimentVariant, Update:ExperimentVariant, Delete:ExperimentVariant, View:ExperimentGoal, Create:ExperimentGoal, Update:ExperimentGoal, Delete:ExperimentGoal, View:ExperimentAudienceRule, Create:ExperimentAudienceRule, Update:ExperimentAudienceRule, Delete:ExperimentAudienceRule; access also governed by package policies: AbstractExperimentsResourcePolicy, ExperimentAudienceRulePolicy, ExperimentGoalPolicy, ExperimentPolicy, ExperimentVariantPolicy.
  • Public routes: loads routes/experiments.php; registers ExperimentsRuntimeRoutesContribution.
  • Database changes: package migrations are declared.
  • Config: config/capell-experiments.php.
  • Settings: no package settings declared.
  • Queues or schedules: scheduled commands capell:experiments:prune (daily; package registered), capell:experiments:sync-statuses (everyFiveMinutes; package registered).
  • Cache tags: experiments.
  • Commands: capell:experiments:prune, capell:experiments:sync-statuses.

Common Pitfalls

Section titled “Common Pitfalls”
  • Keep required Capell packages on compatible v4 releases: capell-app/admin, capell-app/core.
  • Run migrations before opening package resources or public routes.
  • Review package configuration before production-like verification: config/capell-experiments.php.
  • Review middleware, throttling, signatures, and public-output safety in routes/experiments.php before exposing routes.
  • Keep the host Laravel scheduler running so package-registered schedules can execute: capell:experiments:prune (daily; package registered), capell:experiments:sync-statuses (everyFiveMinutes; package registered).
  • Keep public Blade and cached HTML free of authoring markers, model IDs, permissions, signed editor URLs, and lazy database queries.
  • Custom write integrations must preserve invalidation for experiments cache tags.

Troubleshooting

Quick Start

Section titled “Quick Start”
  1. Install the package: composer require capell-app/experiments.
