Convert, validate and tidy YAML through a fast, fully-local API. Turn YAML into JSON (including multi-document streams) or JSON into clean YAML with optional key sorting and custom indentation, validate a document and get the exact line and column of any syntax error with a context snippet, or reformat and normalize existing YAML. Inputs can be sent as a raw text/plain body, a JSON field or a query parameter; outputs are tidy JSON. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for DevOps and CI/CD, configuration and infrastructure-as-code tooling, no-code platforms, editors and data pipelines.

A fast, fully-local cron-expression toolkit (UTC): validate 5-field cron expressions with ranges, lists, steps, month and weekday names and the common @aliases (@yearly, @monthly, @weekly, @daily, @hourly); compute the next N run times for a schedule from now or any start date; and describe a schedule in plain English. Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for schedulers and job runners, devops and CI tooling, and dashboards that show the next run time of a task.

Una calculadora de IP y subred rápida y completamente local: valida direcciones IPv4 e IPv6 con clasificación de tipo (privada, pública, loopback, link-local, multicast, CGNAT o reservada), calcula detalles de subred CIDR (red, máscara de red, wildcard, broadcast, primer y último host, direcciones totales y hosts utilizables, con tamaño de red y rango IPv6), verifica si una dirección está dentro de un bloque CIDR y convierte direcciones (IPv4 a entero, hexadecimal y binario; expandir y comprimir IPv6). Cada endpoint acepta entrada mediante la cadena de consulta o el cuerpo de la solicitud. Cálculo puro del lado del servidor, sin terceros upstream, por lo que las respuestas son instantáneas y siempre están disponibles. Ideal para devops, automatización de redes, IPAM, herramientas de firewall y ACL, e infraestructura en la nube.

Resolve DNS records — A, AAAA, MX, NS, TXT, CNAME, SOA, SRV, CAA, PTR — for any domain, fetch all common records in a single call, or run a reverse PTR lookup for an IPv4 address. Backed by Google DNS-over-HTTPS. Ideal for devops tooling, uptime and email-deliverability checks (SPF/DKIM/DMARC), security research and domain monitoring.
