Engineering transparency for the modern web. We build the infrastructure that helps search engines, developers, and publishers understand site architecture at scale.
Sitemap.xml was founded in 2018 by a small team of search engine researchers and full-stack developers frustrated by the fragmented state of web discovery tooling. What began as an internal utility to standardize URL discovery across enterprise content management systems quickly evolved into a public-facing platform serving over 50,000 properties worldwide.
Our core belief is simple: the web only functions when it can be navigated. We write the code that connects publishing systems with search crawlers, ensuring content reaches the right audiences without manual overhead or indexing bottlenecks.
To eliminate indexing friction by providing reliable, standards-compliant discovery tooling that works across every framework, CMS, and deployment pipeline.
A web where content is automatically and accurately discovered, understood, and ranked by search engines, powered by open standards and developer-first design.
We build to open protocols (RFC, W3C) before proprietary abstractions, ensuring long-term interoperability.
Clear documentation, visible roadmaps, and open-source components where possible. No black-box crawlers.
Enterprise-grade uptime, deterministic routing, and comprehensive fallback mechanisms for critical discovery pipelines.
APIs designed for DX, not just DRY. We listen to maintainers, respect versioning, and ship stable releases.
