Fibr

Fibr AI is an Agentic Web Experience Platform that turns static URLs into intelligent, adaptive landing pages that sense visitor intent and reshape themselves in real time using AI agents with human oversight. Its core product, Fibr Web Pilot, combines no-code A/B testing, conversion-rate optimization (CRO), and personalization — including ad-to-landing-page matching, audience and LLM-visitor personalization, bulk page creation, and AI-driven experimentation — for enterprises, agencies, and growth marketers. The platform integrates with Google Ads, Meta Ads, GA4, CDPs, and major CMS tools, and also ships a large library of free AI marketing tools (headline, hook, CTA, caption, and copy generators, a CRO audit, a landing-page analyzer, and an LLMs.txt generator). Founded in 2022-2023 by Ankur "AJ" Goyal and Pritam Roy and backed by Accel, Fibr is offered through Starter, Agency, and Enterprise pricing tiers. Fibr does not currently publish a public developer API or OpenAPI; this profile captures its identity, developer-adjacent surface, and security/compliance posture.

Fibr is profiled on the APIs.io network. Tagged areas include Company, Conversion Rate Optimization, Personalization, Landing Pages, and A/B Testing.

Fibr’s developer surface includes documentation, pricing, engineering blog, signup flow, support, getting-started guide, changelog, and 16 more developer resources.

  note: All three published tiers (Starter, Agency, Enterprise) terminate in a sales motion — Talk to Sales, Book a Demo or
    Explore More. No price, currency or billing period is published on any tier and there is no self-serve signup. The free
    AI marketing tools at fibr.ai/tools are no-login lead-generation utilities, not a plan tier.

  note: 'Full contract discovery re-run (STEP 0b) across six Fibr-controlled hosts plus the getfibr.co runtime domain — no
    OpenAPI, no GraphQL, no MCP, no agent card, no /.well-known/ document of any kind. Real published surfaces were harvested
    instead: dated product changelog, Content-Signal robots directives, the Fibr Script component, pricing tiers, documented
    integrations and the docs llms.txt.'
x-coverage:
  state: none
  reason: no-developer-program
  detail: Fibr ships its platform only as an end-user product — the entire developer surface is one per-workspace JavaScript
    tag retrieved from the authenticated dashboard, and the GitBook documentation index (support.fibr.ai/llms.txt, 200) lists
    no API, webhook or SDK section at all.
