Made for engineering

Code that prints revenue.

Plug Apex into your stack in two lines. Every experiment, flag, and webhook tied straight to the revenue line.

Meet Apex

Start with an idea

Describe the test you want to run, the page, the audience, the metric, and Apex turns it into a real experiment.

Your unfair advantage

Apex validates every idea against competitor signals, 4,000+ documented experiments from Drip, and live consumer research.

Watch it come to life

Apex generates the variation, writes the code, and ships it to your store in real time. No engineering needed.

Refine in plain language

Iterate with simple feedback, run as many variants as you need, and let Apex call winners.

Install. Integrate. Trust.

Three primitives engineering teams plug into Apex, in one platform.

Drop one snippet. Done.

5kb edge script that works on Next.js, Nuxt, Astro, Shopify Hydrogen — anything React-based. No middleware, no SSR adapter.

REST, SDKs, webhooks.

Manage every resource over REST. Six first-party SDKs generated from the OpenAPI 3.1 spec. Signed webhooks with 30-day replay.

Watch it pay for itself.

Every experiment, flag, and webhook tied to a number you can show finance. Apex programmes return up to 17.7× across customer cohorts.

Every lever your team needs.

Install once. Manage from your editor. Built to disappear into the rest of your stack.

Sub-200ms variants from a CDN.

5kb edge script delivers variants before your hero paints. Anti-flicker by default, even on SPAs and slow networks.

Six first-party SDKs.

JavaScript, Python, Go, Ruby, PHP, Swift. All type-safe, all generated from the same OpenAPI 3.1 spec, all versioned in lockstep.

Every resource over REST.

Predictable JSON, idempotency keys on every write, cursor pagination on every list. The boring stuff, done right.

Signed, retried, replayable.

HMAC-signed webhook payloads. Automatic retries with exponential backoff. 30-day replay window for incident recovery.

Every deploy, tied to a result.

Start experiments from CI, promote winners automatically, and watch each release land on the dashboards finance actually checks.

Works where your code lives.

Next.js, Nuxt, Astro, Shopify Hydrogen, plain React, vanilla JS. The same install on every framework, the same SDK on every backend.
