BUILT FOR YOUR DEV WORKFLOW

Less friction.
More building.

Spend less time piecing together system output and more time working on your code. Five independent developer tools bring context to debugging, portability checks and local environments.

Debug with context
See where a workload spends its time, understand system metrics and compare what changes between distros.
Stay in your workflow
CLI commands, terminal views and readable output keep investigation close to your code. Pick one tool and use it on its own.
Make changes predictable
Review package plans before applying them. Keep environment definitions in files you can version, inspect and reuse.

FROM QUESTION TO MACHINE / FIVE HANDOFFS

One machine.
Every question in view.

Each tool owns one kind of question. Explore a tool to see what it does, from kernel activity to your homelab.

◎ 01 / OBSERVE In development

Omniscient

Linux observability, straight from the kernel.

perf_event_open, eBPF, procfs, sysfs and netlink — no perf, bpftrace or bcc underneath. Every number says what it lost, how it was obtained and how far it can be trusted.

omn top -- ./your-program

9 families · tested on 17 distro images + 5 variants, arm64 and containers · repository not public yet · MIT / Apache-2.0

? 02 / EXPLAIN v0.1

ATFQ

A Linux companion for the terminal.

Short answers first, your machine’s real state second, the deep “why” only if you want it. Never runs your commands, never changes the system, never touches the network.

⧉ 03 / VERIFY v0.1

distroproof

Check that your program holds on every distro.

Boots VMs on the real kernel of each target distro, runs your program there, and compares failing targets with passing ones using environment facts — libc, BTF, perf policy, lockdown and memlock limits.

▥ 04 / RECONCILE v0.1

xpac

Package inventory, provenance and conservative plans.

Lists what is installed and why, explains dependencies, and reconciles packages and dotfiles against a declarative TOML profile — through a plan you can read, save and dry-run first.

xpac plan -f system.toml

◰ 05 / PROVISION In development

VMAnyware

Reproducible environments on your own Proxmox homelab.

Define an environment once, provision it on Proxmox, then manage and reach it from desktop or mobile. A native client and a self-hosted control plane.

native/API workflows tested · real homelab acceptance pending · MIT / Apache-2.0
