Apex

Apex is an e-commerce experimentation platform that brings A/B testing, feature flags and personalization into one toolkit. It fits established shops that want control across storefronts, server-side experiences or mobile apps. Its strongest case is the safeguards around launching and judging tests; the Starter trial gives a bounded way to evaluate them.

Overview

Made by 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, which makes the product a poor match for smaller stores or teams seeking an independent sign-up and immediate access.

For shops that fit that model, Apex combines experimentation with feature flags and personalization, plus visual and code-level ways to create variants. Its breadth is useful when testing needs to span more than standard storefront pages, though the program-based route and custom pricing above Starter make evaluation less straightforward.

Key features

Testing with controls

Apex is designed for six to ten concurrent tests. It checks for conflicts before launch and can automatically pause a losing test. Each experiment needs a primary metric, a planned sample size and a planned duration; results stay hidden until 100 conversions. The default winner threshold is 80% confidence and can be raised to 99%, helping teams set a stricter bar before making a change permanent. The conversion minimum also means low-volume tests may take longer before results are visible.

Variants, prediction and safety

Apex Operator reads a live page and creates structured edits or code-level changes, with each variant reviewed before launch. That gives teams a way to build more tailored changes while keeping approval in human hands. Its Likelihood to Win score draws on matched evidence from 4.3 million tests, research on the shop and live results, offering an additional signal alongside experiment outcomes.

Guardian can pause a variant that is breaking or harming results at a stated 99% bar, return traffic to the control and post explanations to Slack. These launch and monitoring safeguards suit teams running several experiments at once, particularly where a poor variant could affect a live shop.

Store and developer connections

Apex supports Shopify, Shopware, WooCommerce, Centra, headless React and Nuxt stores, custom storefronts, GA4, Tag Manager and consent managers. Its other integrations include Microsoft Clarity, Hotjar, Slack, Microsoft Teams, Google Chat, Figma, Jira, GitHub, OpenAI Codex and Claude Code. Developers get a versioned REST API, signed webhooks, a CLI, an MCP server, a browser SDK with React bindings, and SDKs for JavaScript, Python, Go, Ruby, PHP and Swift. API keys are limited to 100 requests per minute.

Pricing

Apex Starter

Starter costs nothing, 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 30-day trial also includes AI Builder, read-only pattern library access and a real-time dashboard. After the trial, tests pause and data remains read-only for 14 days. Community and email support are included. This is a tightly capped evaluation tier, not a durable option for a shop that needs more experiments, visitors or retention.

Apex and Apex Enterprise

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. It is the fit for teams that need more capacity and control than Starter provides.

Apex 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 depth is aimed at organizations seeking an extended optimization team; annual terms make it a larger commitment than Starter.

Although Apex is described as freemium with a free plan and 30-day trial, its availability inside a DRIP program is central to access. The Starter offer provides a defined trial, but the product is not self-serve.

Platforms

Apex supports Android, iOS, web and API access. Its test types cover A/B, multivariate, server-side and mobile-app experiments, with audience targeting, feature flags, a visual editor and a mobile SDK. The maker says the application and analytics run in London and the database in Ireland; it says Apex does not fingerprint visitors or store their IP addresses and waits for consent where a consent manager requires it. Its SOC 2 and ISO 27001 audit package is prepared, though the audit has not begun.

Who it's for

Apex is best suited to established e-commerce shops with substantial monthly revenue, a team able to work within a DRIP program and a need to coordinate experiments across storefronts or app experiences. Teams that value pre-launch conflict checks, evidence thresholds and automatic safeguards have a clear reason to consider it. Smaller retailers, teams that need immediate self-serve access or buyers who require completed security audits should look elsewhere.

Pros and cons

• Pros: Conflict checks, automatic pausing and configurable confidence thresholds add concrete controls for teams running concurrent tests.
• Pros: Storefront, analytics, consent and developer integrations support a range of e-commerce setups, including headless and custom stores.
• Pros: The Starter trial provides three live experiments and 10,000 tested visitors per month without a card, making a limited evaluation possible.
• Cons: Access is restricted to a DRIP program, so teams cannot simply sign up and begin testing independently.
• Cons: Starter is capped at three live experiments, 10,000 monthly tested visitors and seven-day custom data retention; experiments pause after its 30-day trial.
• Cons: Apex and Enterprise use custom pricing, and Enterprise requires an annual contract.
• Cons: The SOC 2 and ISO 27001 audit has not begun, which may not satisfy buyers who require completed audits.

Alternatives

For a broader comparison, see A/B Testing Tools. Choose Experimently if self-hosting on your AWS account and a free plan with all features included matter more than Apex’s DRIP program and e-commerce-specific positioning. Featureflip is a simpler starting point for a solo developer: its free Solo plan allows 10 flags per project, two environments and one developer. Confidence by Spotify suits teams seeking a free feature-flag plan with 75,000 monthly credits, unlimited flags and seats, and up to five surfaces.

Pick Crazy Egg if web analytics, heatmaps, conversion analytics and surveys are the priority, with a free plan and a Starter plan at $29 a month. DevCycle is another freemium option for teams looking for feature management, with a free plan that includes 1,000 client-side MAUs and monthly cloud and server configuration request allowances. Firebase Cloud Messaging is a no-cost choice for cloud messaging. GrowthBook is worth considering for teams that want a self-hosted, open-source option with unlimited feature flags, experiments and traffic on its free plan. LaunchDarkly Experimentation offers a free Developer plan with 100K experimentation MAU per month, one project and three environments.

Verdict

Choose Apex if your established shop can enter a DRIP program and needs experimentation, flags and personalization backed by launch safeguards and broad store and developer connections. The Starter trial gives teams a defined, no-card evaluation, while its capped capacity and 14-day read-only period limit how far that evaluation can go. Look elsewhere if you need self-serve access, a lasting free tier at higher volume or completed SOC 2 and ISO 27001 audits.
