Apex vs Featureflip

Apex combines A/B testing, feature flags, and personalization for e-commerce. It supports A/B, multivariate, server-side, and mobile-app tests, and is designed for six to ten concurrent experiments with pre-launch conflict checks. Each test requires a primary metric, planned sample size, and duration; results are withheld below 100 conversions. The default winner threshold is 80% confidence and can be set as high as 99%. Apex Operator reads a live page and prepares structured or code-level edits for review before launch. Guardian can pause a variant that is breaking or harming results, return traffic to control, and post an explanation to Slack. Its Likelihood to Win score uses matched evidence from 4.3 million tests, shop research, and live results. Integrations include Shopify, Shopware, WooCommerce, Centra, headless and custom storefronts, analytics, consent managers, and team tools. Developer access includes a versioned REST API, webhooks, CLI, MCP server, and SDKs; API keys have a limit of 100 requests per minute. Apex is made by Drip Trading GmbH and is available only inside a DRIP program. The free Starter plan is listed at free, with no card required; custom pricing applies to Apex and Enterprise.

Featureflip provides feature flags for changing functionality in a running application without deploying new code. It supports percentage rollouts, targeting rules, kill switches, A/B tests, and isolated environments. When a flag is no longer needed, its GitHub Action can open a reviewable pull request to remove the code path across thirteen languages and archive the flag after merge. Teams can manage flags through a REST Management API or evaluate them through the Evaluation API; thirteen SDKs and OpenFeature providers are listed. Server SDKs evaluate locally from in-memory configuration and keep using the last configuration if the service is unreachable. Featureflip also offers an MCP server for Claude Code, Cursor, Copilot, and Cline, plus a Terraform provider. Its service and PostgreSQL database run on Hetzner Cloud in the European Union. The Free plan is free and is limited to one project, 10 flags per project, two environments, and up to three team members. Team is $49 a month; Pro is $99 a month; Business is $249 a month. Enterprise pricing is negotiated directly.
