#parser

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.

A fast, fully-local HTML toolkit: extract structured data from supplied HTML (title, meta description, canonical link, language, Open Graph and Twitter card tags, links, images, headings and word counts), convert HTML to readable plain text, list all links resolved against a base URL, and sanitize HTML with a strict allowlist (scripts, iframes, inline event handlers, javascript: URLs and unknown tags are stripped). It works on the HTML you send and never fetches URLs (for live link previews see the oanor URL Tools API). Input via the query string or the request body, up to 2 MB. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for scrapers and data pipelines, comment and email sanitization, RAG and content extraction, and CMS tooling.
