Tools for DevOps Engineers
DevOps engineers work at the intersection of development and infrastructure. Between writing CI/CD pipelines, managing Kubernetes configs, debugging webhooks, and incident response, there's a constant stream of small browser-based tasks that don't need a full script — just a fast tool. Here are the Tools.Fun utilities that fit naturally into a DevOps workflow. All run entirely in your browser, no login required.
Crontab Calculator
Validate cron expressions before deploying them to production schedulers. The tool explains the schedule in plain English and shows the next 10 execution times. Supports standard 5-field cron syntax and common shorthands (@daily, @hourly). Prevents the perennial "maintenance window at the wrong time" incident.
spec.schedule), GitHub Actions schedule: triggers, Jenkins cron syntax, AWS EventBridge rules, and Linux crontabs.Code & Config Diff Tool
Compare two versions of a Dockerfile, Nginx config, Helm values.yaml, Terraform plan output, or CI pipeline YAML side by side. Faster than running git diff when you're mid-incident reviewing an artefact in a browser tab.
JSON Formatter & Validator
Pretty-print and validate JSON from CI artefact outputs, Kubernetes API responses, API health checks, and ALB/CloudFront access logs. Spot malformed configs before they trigger a deployment failure or alert storm.
JSON to YAML Converter
Convert JSON configs to YAML for Helm charts, Kubernetes manifests, GitHub Actions workflows, and Ansible playbooks. Skip the manual reformatting when translating between config formats across tools.
Base64 Encoder / Decoder
Decode Kubernetes Secret values (kubectl get secret -o yaml outputs base64), Docker config JSON, and CI environment variables. Encode raw values for embedding in manifests or pipeline configs without leaving your browser.
kubectl get secret my-secret -o jsonpath="{.data.password}" — paste the output here to decode instantly. No terminal pipe needed.cURL Converter
Convert cURL commands into structured request breakdowns for runbooks and incident documentation. Build cURL commands from scratch for testing API endpoints during deployment verification. Share reproducible HTTP requests with teammates who prefer a visual format.
WebSocket Tester
Connect to any WebSocket endpoint and send / receive messages in the browser. Test Kubernetes operator webhooks, push notification services, real-time log streamers, and event-driven microservices without installing a CLI client or writing a test script.
IP Lookup
During incidents, quickly identify the geolocation, ASN, and hosting provider behind an IP address from VPC flow logs, WAF logs, or security alerts. Determine whether traffic is from a known cloud provider or a suspicious origin.
Timestamp Converter
Convert Unix timestamps from Kubernetes event logs, CloudWatch, Loki, Elasticsearch, and Datadog to human-readable dates while triaging incidents. Generate epoch values for time-range query filters without mental arithmetic.
kubectl describe pod gives events with relative timestamps. Use the converter to find the exact UTC time of a failure for cross-correlating with other log systems.RegExp Tester
Test log parsing patterns and alert rule expressions in real time. Useful for writing Loki LogQL regex filters, Prometheus alerting rule patterns, Fluentd / Fluent Bit record_transformer regex, and Nginx log format extractors.
Password Generator
Generate strong random credentials for service accounts, database users, Kubernetes ServiceAccount tokens, and API integrations across environments — without reusing or manually typing passwords.
MD5 / Hash Generator
Verify Docker image layer checksums, compare artefact hashes from build pipelines, and generate SHA-256 digests for integrity verification in supply chain security workflows.
QR Code Generator
Generate QR codes linking to internal dashboards, runbook pages, on-call rotation URLs, and monitoring views. Useful for printed runbooks in data centres and office wall dashboards.
Code to Image
Turn code snippets into clean images for post-mortems, incident reports, Confluence documentation, and Slack messages where code blocks don't render correctly or need to be embedded as images.
URL Encoder / Decoder
Encode special characters in webhook URLs, JDBC connection strings, and Kubernetes ingress annotations. Decode percent-encoded URLs from access logs and redirect chains during debugging.
Hex Converter
Convert hexadecimal values when working with network packet captures, Kubernetes resource version hashes, and binary configuration data in infrastructure tooling.
User-Agent Parser
Parse User-Agent strings from ALB access logs to identify bot traffic, legitimate crawlers, and suspicious automated clients when tuning WAF rules and rate limiting policies.
AES Encryptor
Test AES encryption for secrets management integrations. Verify that your application correctly encrypts and decrypts config values using the same key and IV before deploying to production.
Duplicate Line Counter
Remove duplicate IPs, hostnames, or resource identifiers from lists when building firewall rule sets, security group entries, and host inventory files.
Character Counter
Verify that environment variable values, secret strings, and annotation values stay within the character limits imposed by your container platform or secrets manager.
