Open-source tools

Tools I build and run

Free, open-source developer and everyday tools: Kubernetes guardrails, a JVM container check, a log viewer, local file tools and a self-hosted health record. Each one started as something I needed myself.

k8s-guardian

Open-source CLI that checks and safely fixes Kubernetes manifests, Helm charts and Kustomize overlays, tests whether they fit the live cluster, and exports the same rules as admission policies.

jvm-fit

Open-source CLI that reads a pod spec and its JVM flags together and tells you before deploy whether the JVM fits: heap plus non-heap against the memory limit, CPU limits and GC choice, startup probes.

Logbeam

Free browser extension that turns a raw log into a searchable viewer: levels, regex search, field filters, error groups, CI run comparison and secret masking. Runs locally, nothing leaves the browser.

FileForge

More than 50 free file tools that run in your browser: HEIC to JPG, compress and resize images, merge, split and sign PDFs, Markdown to PDF, CSV to JSON. Works offline, nothing is uploaded.

Health OS

Open-source, local-first personal health record exposed over MCP: labs, medications, diagnoses, wearables and a food log in your own Postgres, with safety rules written as code instead of prompts.
