About OpsBash
Professional tools for engineers who live in terminals, write Kubernetes manifests, and debug cron jobs at 2 AM.
The story
OpsBash started from a simple frustration: most online DevOps tools are either covered in ads, locked behind accounts, or just wrong. A cron expression validator that doesn't understand AWS EventBridge syntax. A base64 encoder that sends your data to a server. A "free" tool that's free for three uses.
DevOps engineers work with Linux schedulers, AWS CloudWatch Events, Kubernetes CronJobs, and GitHub Actions pipelines, sometimes all on the same day. Each platform has its own cron dialect, its own quirks, its own edge cases. You shouldn't have to look that up from a 10-year-old Stack Overflow answer.
OpsBash is built to fix that. Every tool is purpose-built for the specific needs of operations engineers: accurate, fast, private, and completely free.
Our mission
- Solve real daily problems. Every tool exists because a real DevOps engineer ran into a real problem. Not because it fills a feature matrix.
- Be accurate, not just functional. The cron builder correctly handles Linux/Unix, AWS EventBridge (6-field format with
?wildcard), GitHub Actions UTC scheduling, and Kubernetes CronJob manifests, with the actual syntax differences between them rather than a one-size-fits-all approximation. - Keep it private. Every tool runs entirely in your browser. No cron expressions, no configuration data, no user input of any kind is transmitted to our servers.
- Stay free. No accounts. No pricing tiers. No "basic" vs "pro" split that puts the features you actually need behind a paywall.
- No fluff. No hero videos, no testimonial carousels, no cookie-consent pop-ups covering the tool you came to use. Just the tool.
