Apex

Apex is an experimentation and personalization suite for e-commerce, with tools for storefront, server-side and mobile-app testing. It is aimed at shops prepared to work within a DRIP program; its safeguards and developer access stand out, but teams cannot simply sign up and begin a trial.

For retailers with a defined testing plan and technical support, Apex brings experiment controls, variant-building tools and store integrations together. Its program-only availability and custom pricing make it a poor fit for smaller shops or teams that need independent, predictable access.

Overview

Apex, a product of Drip Trading GmbH, is available only inside a DRIP program. The maker invites shops doing €100k or more a month to book a call about fit. That makes it a considered option for established e-commerce businesses, not an off-the-shelf tool for a shop that wants to get started on its own.

The product spans A/B testing, feature flags and personalization, with visual and code-level editing options. Its breadth is useful for teams running experiments across different store architectures; the program requirement remains the central buying constraint.

Key features

Structured experiments and safeguards

Apex supports six to ten concurrent tests, checks for conflicts before launch and can automatically pause a losing test. Each test needs a primary metric, planned sample size and duration. Results stay withheld until 100 conversions; the default winner threshold is 80% confidence and can be raised to 99%. Those constraints encourage planned, evidence-led testing, but teams cannot use Apex to call a winner before the conversion minimum is reached.

Guardian can pause a variant that is breaking or harming results at a stated 99% bar, return traffic to control and explain the action in Slack. This is a meaningful safeguard for teams concerned that an experiment could damage a live store, though it does not remove the need to choose sound metrics and test plans.

Variant building and prediction

Apex Operator reads a live page and creates structured edits or code; an operator reviews each variant before it goes live. That review step keeps AI-generated changes from launching unchecked, while code-level variants make the tool better suited to teams that can evaluate technical changes than to shops seeking a purely no-code workflow.

Its Likelihood to Win score draws on matched evidence from 4.3 million tests, research on the shop and the shop’s live results. That gives teams another input when evaluating a test, rather than a replacement for the required metric, sample size and duration.

Integrations, API and privacy

Store connections include Shopify, Shopware, WooCommerce, Centra, headless React and Nuxt, custom storefronts, GA4, Tag Manager and consent managers. The wider integrations directory also includes Microsoft Clarity, Hotjar, Slack, Microsoft Teams, Google Chat, Figma, Jira, GitHub, OpenAI Codex and Claude Code. This range should suit teams with established analytics and development workflows.

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. The API limit is 100 requests per minute per key, a practical constraint for high-volume integrations. 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 a consent manager requires it. Its SOC 2 and ISO 27001 audit package is prepared, but the audit has not begun.

Pricing

Apex Starter

Apex Starter costs nothing, billed Free forever, with no card required. It allows three live experiments, 10,000 tested visitors per month, one environment, three seats, one workspace, five custom metrics and seven-day custom data retention. This is a genuinely bounded starting tier for a small team evaluating the workflow, but the experiment, visitor, seat and retention caps limit its usefulness for ongoing or larger-scale testing.

The separate Starter free trial runs for 30 days and 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, while data remains read-only for 14 days. Starter includes community and email support. The trial is not a route around program-only access: Apex is available only inside a DRIP program.

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, RBAC and data residency. It fits teams that have outgrown Starter’s caps or need those governance and testing options, but the cost depends on a custom arrangement.

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 businesses that want a broader testing team alongside the software; annual terms make it a less flexible fit for short-term needs. Apex lists a dedicated success manager and a 99.9% SLA, while Enterprise includes a dedicated conversion manager and regular reviews.

Platforms

Apex supports web and mobile, including mobile-app testing, and offers API access. Its listed integrations cover Shopify, Shopware, WooCommerce, Centra, headless and custom storefronts, as well as analytics and consent tooling. That combination is most relevant to retailers whose experiments need to span more than a standard web page; teams outside e-commerce have less reason to choose it.

Who it's for

Apex is best suited to established e-commerce shops doing €100k or more a month, with technical integrations and a defined testing program. Its concurrency, launch checks and broad developer access favor teams able to plan experiments and review code-level variants. It is not the right choice for a smaller shop, a team that needs a self-serve trial, or anyone who needs clear fixed pricing before contacting the maker.

Pros and cons

Pros: Conflict checks, minimum-conversion requirements and Guardian’s pause-and-revert behavior give experiment teams concrete safeguards against premature decisions and harmful variants.

Pros: Support for storefront, server-side and mobile-app testing, alongside a wide integration and SDK range, makes Apex relevant to technically varied commerce stacks.

Pros: Starter is free forever, requires no card and states its visitor, experiment, seat and retention limits clearly.

Cons: Access is only through a DRIP program, so teams cannot independently start a plan or trial.

Cons: Beyond Starter, pricing is custom; Enterprise also requires an annual contract, making costs and commitment less straightforward to assess.

Cons: Starter caps experiments at three and tested visitors at 10,000 per month, and has only seven-day custom data retention.

Alternatives

For a broader shortlist, see A/B Testing Tools. Consider Confidence by Spotify if a free plan with unlimited feature flags and seats, up to five surfaces and EU or US hosting is a better match. Its free tier is credit-capped at 75,000 credits per month.

LaunchDarkly Experimentation is worth considering when a free Developer plan with 100K experimentation MAU per month, one project and three environments fits the need. Webtrends Optimize may suit a website below 10,000 monthly sessions that wants a free account with the same features as its paid version.

Choose Zoho PageSense if its Forever Free allowance of 5,000 tracked users per month, one project, one month of retention and five goals fits the workload. Crazy Egg is another alternative. Experimently may fit teams seeking a self-hosted AWS preview with all features included and no trial.

Mida is worth comparing for its no-time-limit Sandbox, 100,000 monthly tested users, 50,000 daily tracked events and 60-day retention. Featureflip is an alternative for teams focused on feature flags, with a free Solo plan capped at 10 flags per project, two environments, one project, one developer and seven-day audit logs.

Verdict

Choose Apex if you run an established e-commerce shop inside a DRIP program and need disciplined testing across storefront, server-side or mobile experiences, backed by developer integrations and safeguards. Its strongest case is the combination of testing controls and technical breadth; its clearest reason to look elsewhere is that program-only access and custom pricing prevent teams from starting independently or knowing the full cost upfront.
