Each tool is built to do one job well, without collecting your data.

KUBERNETES
Available nowA free, privacy-first tool for DevOps engineers, SREs, and developers. Build a kustomization.yaml from a guided form, inspect and validate existing manifests, and generate base/overlay folder structures. No cluster access, no uploads, no account, no tracking. Your manifests stay on your device.
Open tool ↗
XML
Available nowA free, privacy-first XML validator. Check that XML is well-formed, or validate it against a DTD or XSD schema. Well-formed checks use the browser parser, DTD validation runs in pure JavaScript, and XSD validation uses libxml2 compiled to WebAssembly, loaded only when needed. No uploads, no account, no tracking - your XML never leaves your device.

WebF1 Tools gathers small, focused utilities we build for ourselves and share with the community. They run in your browser and are built to keep your data private. We do not require an account, we do not serve ads, and we do not run third party analytics or session replay on these pages.
Privacy First
No account. No ads. No tracking. Tools run in your browser and we do not intentionally collect your inputs.
There is no analytics script, no advertising network, and no session replay on WebF1 Tools. The directory links to individual tools, each of which is built with the same privacy-first approach.
WebF1 LLC builds custom business systems, integrations, and practical software tools. This directory is one way we give back to the community. If your team relies on repeated spreadsheets, manual calculations, disconnected systems, or fragile processes, WebF1 can build software designed around your workflow.
These tools are general-purpose utilities, not professional, legal, financial, or business advice.
