Apex

Apex brings experimentation, feature flags, and personalization together for e-commerce shops. It is built for retailers testing across storefronts, server-side experiences, and mobile apps, with controls that help manage concurrent experiments. Access through a DRIP program is a substantial constraint for teams that want to get started on their own.

Overview

A product of Drip Trading GmbH, Apex is available only inside a DRIP program. The maker invites shops doing €100k or more per month to book a call about fit, making it a more natural match for established retailers than for small shops seeking a standalone tool.

Apex combines A/B testing, feature flags, and personalization. Its range of experiment types and storefront integrations can serve teams working across multiple channels, but the program-based access model shapes the buying decision from the outset.

Key features

Experiments with safeguards

Apex supports six to ten concurrent tests and checks for conflicts before launch. Tests require a primary metric, sample size, and duration; results stay hidden until a test reaches 100 conversions. The default winner threshold is 80% confidence and can be raised to 99%. These rules favor deliberate decisions, though teams must wait to see results when conversion counts are low.

Guardian can pause a variant that is breaking or harming results at a stated 99% bar, return traffic to the control, and post an explanation to Slack. That gives teams a way to limit the exposure of a problematic change while retaining the original experience.

Variant creation and prediction

Apex Operator reads a live page and creates structured edits or code for a variant. Operators review each version before launch, so generated changes do not go live without approval. The Likelihood to Win score draws on matched evidence from 4.3 million tests, research on the shop, and live results. It offers an additional input for prioritizing experiments, while the required test criteria and conversion threshold still govern when results appear.

Storefronts and developer access

Apex supports visual and code-level editing, A/B and multivariate experiments, server-side tests, and mobile-app tests. Its integrations span Shopify, Shopware, WooCommerce, Centra, headless React and Nuxt, custom storefronts, GA4, Tag Manager, and consent managers. Slack, Microsoft Teams, Google Chat, Figma, Jira, GitHub, OpenAI Codex, and Claude Code are also in its integrations directory.

Developers get a versioned REST API, signed webhooks, a CLI, an MCP server, and a browser SDK with React bindings; SDKs are also offered for JavaScript, Python, Go, Ruby, PHP, and Swift. API access is limited to 100 requests per minute per key, a relevant ceiling for teams building frequent automated workflows.

Privacy and security

Apex says its application and analytics run in London and its database in Ireland. It says it does not fingerprint visitors or store their IP addresses, and waits for consent where required by a consent manager. Its SOC 2 and ISO 27001 audit package is prepared, but the audit has not begun, so those certifications should not be treated as completed.

Pricing

Apex Starter

Starter is free, billed Free forever, with no card required. It includes three live experiments, 10,000 tested visitors per month, one environment, three seats, one workspace, five custom metrics, and seven-day custom data retention. The free tier gives small teams a defined way to run limited tests, but its visitor and experiment caps constrain shops with larger testing programs.

The 30-day Starter trial includes three live experiments, 10,000 tested visitors, AI Builder, read-only pattern library access, and a real-time dashboard. Tests pause when the trial ends, and data remains read-only for 14 days. Starter also includes community and email support.

Apex

Apex has custom pricing, tailored to traffic and team size. It includes unlimited experiments and visitors, a custom code editor, multivariate, server-side, and mobile-app testing, approval workflows, SSO, MFA, role-based access control, and data residency. This is the tier for teams whose testing volume or governance needs exceed Starter, though the buying process requires a custom quote.

Apex Enterprise

Enterprise also has custom pricing, is sized to scope, and uses annual contracts. It adds a dedicated conversion manager, consumer psychologist, data analyst, UX/UI designers, testing engineers, and QA. That service model may suit retailers seeking a broad specialist team around optimization, while annual terms and custom pricing make it a more involved commitment.

Platforms

Apex supports web and mobile, with Android, iOS, API, and web platforms. Mobile-app testing and a mobile SDK extend its scope beyond storefront experiments.

Who it's for

Apex is aimed at established e-commerce shops, particularly those doing €100k or more per month and able to participate in a DRIP program. It suits teams that need experimentation across storefronts, server-side systems, or mobile apps, and value launch checks, traffic safeguards, and developer tooling. It is a poor fit for shops that need self-serve access or cannot work within Starter's visitor and experiment limits.

Pros and cons

• Broad testing scope: A/B, multivariate, server-side, and mobile-app testing cover more than storefront-only experiments.
• Useful launch and safety controls: Conflict checks, conversion thresholds, and Guardian's pause-and-revert behavior help contain competing or harmful variants.
• Substantial integration and developer coverage: Storefront integrations, multiple SDKs, webhooks, and a versioned API support both commerce and engineering workflows.
• Access depends on a DRIP program: Teams cannot sign up independently, which rules out buyers who need immediate self-serve access.
• Starter is tightly capped: Three live experiments and 10,000 tested visitors per month may not accommodate a larger testing operation.
• Upper-tier cost and terms require a quote: Custom pricing, and annual contracts for Enterprise, make budgeting less direct.

Alternatives

A/B Testing Tools is a broader category to explore when comparing testing products.

Choose Experimently if self-hosting on your own AWS account and a free preview with all features included matter more than Apex's DRIP-based access.

Featureflip is an alternative with a free Solo plan for teams focused on managing up to 10 flags per project, two environments, and one developer.

Confidence by Spotify may fit teams that want a free feature-flag plan with 75,000 credits per month, unlimited flags and seats, and up to five surfaces.

DevCycle offers a free plan for teams comparing client-side and cloud configuration quotas for feature delivery.

Firebase Cloud Messaging is a no-cost option for teams seeking cloud messaging.

GrowthBook is a fit for teams that want open-source self-hosting with unlimited feature flags, experiments, and traffic on its free tier.

Mida has a free Sandbox plan with 100,000 monthly tested users, 50,000 daily tracked events, and 60 days of data retention.

Verdict

Apex is a strong fit for established shops in a DRIP program that need experimentation across storefront, server-side, and mobile experiences. Its testing safeguards, broad integration coverage, and developer access make it a capable option for teams coordinating many kinds of commerce changes. Look elsewhere if you need to start without a program relationship, or if Starter's three experiments and 10,000 monthly tested visitors are too restrictive.
