§ 01 — why fragments existsproblem.md
Your marketing team doesn't need a sprint to change a banner.
Every UI experiment that goes through a backlog is one that won't happen. Fragments moves the surface layer out of code and into the hands of the people who need it.
▲ Before — life with tickets
✕Every banner, modal or CTA is a ticket. Every ticket is a sprint. Every sprint has six other tickets.
✕Marketing waits three weeks for a colour change. Nobody is happy about this, including the engineers.
✕Experiments require a deploy, so you run one a month instead of one a day.
✕Analytics live in five tools. Nobody knows which variant won, only which one shipped.
▲ After — one SDK, done
→A visual builder your PM can use. Drag, type, publish — banner live in fifteen minutes.
→Targeting by geo, device, plan, cohort, time. Rolls out from the edge, not a release.
→A/B tests, feature flags and scheduled rollouts live inside the same tool you built the widget in.
→Impressions, clicks and conversions attached to every fragment, out of the box.

§ 03 — the platform3 modules · 1 sdk
Three things, one runtime.
A builder that speaks to designers, ships to engineers.
Drag-and-drop canvas, component library, Figma import, data binding, conditional logic, versioning and rollback. Exports production-grade DOM — not an iframe, not a wrapper.

Two things that make us, us.
The rest of the platform is table stakes. These two are why teams stay after the pilot.

Figma → production, one button
Our Figma plugin turns any frame into a live Fragments area. Component names become props, auto-layout becomes CSS, variants become states. No hand-off doc, no developer translation.

AnomalyDetector — always on, quietly
A model watches every live fragment and experiment. When CTR, conversion or latency drifts off-pattern, it pages you. It knows what to ignore — weekends, holiday bumps, planned traffic shifts — so the alerts mean something.
§ 08 — faqcommon questions · last updated apr 2026
Questions we actually get asked.
Optimize is dead and VWO rewrites your DOM with a mutation overlay — slow, fragile, and their builder is from 2014. Fragments renders production-grade native DOM through a purpose-built SDK, with SSR support, a modern builder, and feature flags baked in.
12.4 kb gzipped, zero dependencies, async by default, no render-blocking. p99 time-to-paint for a fragment is under 50ms globally. We publish our perf budget publicly and ship slower if we break it.
Yes. The SDK is framework-agnostic — you mark slots with data-fragment or use the thin adapter for your framework. SSR is supported natively; hydration is clean.
Default EU hosting; RU localization (152-ФЗ-compliant) and US on the roadmap. Custom regions on Enterprise. Fragments ships with consent-mode integration for GDPR and can be configured to not drop a single cookie until the user opts in.
No — that's literally the point of the product. After the one-time SDK install, everything happens in the dashboard. If you need a new slot on a new page, a dev adds one data-fragment attribute. That's it.
On the Enterprise plan, yes — either on-prem or in a dedicated cloud tenant. For most teams, our managed cloud is faster to roll out and cheaper to operate.
