IT Tools

A collection of handy online tools for developers and IT professionals.

IT Tools is a self-hosted collection of developer and IT utilities including token generators, encoders/decoders, converters, formatters, and network tools — all in a fast single-page application. Self-hosting ensures availability on your internal network without relying on third-party websites that may have ads or data retention.

Installation

Architecture

• Deployment: Single it-tools deployment in the it-tools namespace
• Image: ghcr.io/corentinth/it-tools, digest-pinned via Renovate
• Storage: No persistent storage — stateless application
• Networking: ClusterIP service on port 80, HTTPRoute via public gateway; NetworkPolicy restricts ingress to Envoy Gateway only

Security

No securityContext configured. Stateless app with no secrets — minimal attack surface. NetworkPolicy limits inbound traffic.

Updates

Managed by Renovate. Image is digest-pinned.

Data Management

No persistent data. Stateless SPA — all processing runs client-side in the browser.

User Management

No authentication configured. Public access via HTTPRoute.

Configuration Management

No ConfigMaps or Secrets — no configuration needed for this stateless app.

Usage

Access the web UI to use any of the available tools: UUID generation, JWT decoding, color converters, hash generators, network calculators, cron expression parser, and many more. All processing happens client-side in the browser.

Cluster-specific deviations from the above live in the per-cluster README — see k8s/apps/it-tools/talos/README.md.
