DevOps tooling in the browser
Platform engineers and DevOps practitioners constantly work with cron schedules, YAML configs, network ranges, and container commands. Instead of installing CLIs or searching docs, these tools let you validate and convert directly in your browser. For example, the cron parser is a privacy-first alternative to crontab.guru that shows next run times without sending your expressions to a server.
