Engineering judgement,
made testable.
Standards-based engineering utilities with explicit formulae, versioned parsers and deterministic outputs for high-consequence work.
Exact within a defined contract
No readiness scores or AI verdicts. Every active utility exposes its formula, parser, standards version and limitations.
Subnet Splitter
Validate canonical IPv4 CIDR input, visualise subnet boundaries, and calculate exact equal-prefix splits.
K8s RBAC
Construct safely serialized Kubernetes Role and RoleBinding manifests with validated names, subjects, resources, and verbs.
SLO Budget Suite
Calculate exact error budgets, observed SLI and versioned multiwindow burn-rate alert thresholds without floating-point loss.
CIDR Planner
Normalize IPv4/IPv6 networks, calculate exact ranges and audit batch allocations for containment, overlap, alignment and unused capacity.
Configuration Studio
Validate strict JSON/YAML, apply pinned schemas, generate a verified RFC 6902 patch and fingerprint RFC 8785 canonical configuration.
BDP Calculator
Calculate exact data in flight from bandwidth and RTT, with decimal and binary units plus the minimum TCP receive-window capacity.
DB Pool Sizer
Calculate a per-pod connection-pool upper bound from database capacity, peak pod count, and an explicit operational reserve.
Partition Calculator
Calculate the theoretical partition minimum for a throughput target using benchmarked per-partition producer and consumer rates.
Resource Profiler
Generate conservative Node.js, Go, or Java runtime starting policies for a supplied Kubernetes CPU and memory limit, with explicit caveats.
FinOps Estimator
Estimate CI/CD compute cost from build volume, duration, retry overhead, and a user-supplied blended hourly rate, then compare target-duration scenarios.
Cron Translator
Validate five-field Unix cron expressions, explain day-field OR semantics, and calculate deterministic upcoming execution times.
JWT Decoder
Strictly decode compact signed JSON Web Tokens and inspect headers, claims, signature presence, and advisory time checks locally in your browser.
