SRE Toolkit
Site reliability engineers keep production systems running, balancing feature velocity with service-level objectives. The daily work involves debugging incidents, tuning alerting rules, reviewing infrastructure changes, and maintaining runbooks. These free, browser-based tools handle the repetitive micro-tasks that fill the gaps between your monitoring dashboards and deployment pipelines.
Crontab Calculator
Validate cron expressions for Kubernetes CronJobs, systemd timers, and CI/CD scheduled pipelines. See the next ten execution times in plain English — prevent the classic "the batch job ran at 3 AM UTC instead of 3 AM local" incident.
JSON Formatter & Validator
Pretty-print and validate JSON from API responses, Terraform plan output, cloud service configurations, and structured log entries. The formatted view reveals misconfigurations that compact JSON hides.
Code Diff Tool
Compare Terraform state files, Kubernetes manifests, and infrastructure configurations before and after changes. Essential for change review and post-incident analysis.
JSON to YAML Converter
Convert JSON to YAML for Kubernetes manifests, Helm values, Docker Compose files, and Ansible playbooks. Faster than manual reformatting when translating API output to infrastructure-as-code.
RegExp Tester
Build and test regex patterns for log parsing rules, Prometheus relabeling configs, and alerting filters. Live highlighting ensures your pattern matches exactly what you intend before deploying to production.
Timestamp Converter
Convert Unix epoch timestamps to human-readable dates across time zones. Critical for building incident timelines from mixed log sources — CloudWatch, Datadog, Splunk, and application logs all use different formats.
Base64 Encoder / Decoder
Decode Kubernetes secrets (which are Base64-encoded, not encrypted), inspect JWT tokens from service mesh authentication, or encode configuration values for deployment.
cURL Converter
Test API endpoints, health checks, and webhook integrations. Convert cURL commands from runbooks into structured requests for debugging and documentation.
MD5 / Hash Generator
Generate SHA-256 checksums for deployment artifacts, verify container image digests, and validate file integrity during incident investigation.
IP Address Lookup
Look up IP addresses from load balancer logs, CDN access logs, and firewall events. Identify geographic location and ASN to understand traffic patterns during incidents.
URL Encoder / Decoder
Decode percent-encoded strings from access logs and reverse proxy configurations. Encode special characters in webhook callback URLs and API integration endpoints.
Duplicate Line Remover
Deduplicate IP lists from log exports, clean up alert notification recipients, and remove duplicate entries from configuration files during incident triage.
