Free domain, IP and ASN reports for hosting, DNS, network routes and public website diagnostics.

Overview

What is heade.rs?

Free domain, IP and ASN reports for hosting, DNS, network routes and public website diagnostics. heade.rs review: a clear first look at a website’s public infrastructure Editorial draft in Ashley Richmond’s voice.

Editorial

Why we recommend it

A readable first stop for public domain/IP/ASN infrastructure checks, with no-key JSON, terminal formats and MCP. Use only non-sensitive targets: queried names appear in public activity. Verify high-stakes findings separately; CDN location, nearby-probe traces, header grades and metadata-based CVEs are clues, not complete audits. Public UI inspection and desk research only.

Audience

Best for

Developers investigating public website infrastructure
Site operators checking DNS and mail-policy clues
Network investigators using non-sensitive targets

Capabilities

Key features

Domain, IP and ASN reports

Public domain/IPv4/IPv6/AS lookup; URL input extracts hostname. Different report fields apply to domain/IP and network targets.

Hosting and route context

Resolved network/prefix, RPKI, approximate geography and available cloud/CDN clues. Browser route uses a nearby Globalping probe, not your…

DNS and registration

DNS records, DNSSEC, RDAP/WHOIS registration and name servers, with missing/source-failure states.

Mail-policy signals

Provider/MX, SPF, DMARC, MTA-STS, TLS-RPT and BIMI when available; not a complete email-authentication audit.

HTTPS and header checks

Certificates/Transparency and security-header grade. Point-in-time indicators, not penetration testing or site certification.

Pros

Broad public infrastructure coverage in one readable report
No-account/no-key access with documented output formats
Technology findings include the visible evidence behind them
Help distinguishes source freshness and measurement limits

Cons

Query names appear in public recent/seven-day activity
No product privacy/terms/retention policy verified
Nearby-probe route and CDN geography do not prove actual user path or origin
Third-party/version/header signals can be incomplete or stale

Plans

Pricing

Free plan

Free - no account or API key

Summary

Final verdict

A readable first stop for public domain/IP/ASN infrastructure checks, with no-key JSON, terminal formats and MCP. Use only non-sensitive targets: queried names appear in public activity.

Loupe for Kubernetes

Free, open-source desktop client for Kubernetes clusters

3.5

33

AppsInsight Score

Overview

What is Loupe for Kubernetes?

Free, open-source desktop client for Kubernetes clusters Loupe is a free, open-source desktop client for Kubernetes.

Editorial

Why we recommend it

A clear, honest open-source Kubernetes client: kubectl-matching columns, a diff before every apply, per-context read-only and protected modes, no telemetry and no price. It is young (first release August 2026, version 0.1.7) and I did not run it. Desk-research score 3.5/5.

Audience

Best for

Engineers who live in kubectl and want a desktop view; people who left Lens or OpenLens over licensing; teams that want an Apache-2.0 tool they can audit; anyone with a huge kubeconfig; operators who want a protected mode for production contexts

Capabilities

Key features

Live resource browser

Pods, workloads, networking, config, storage, Helm releases and any custom resource, kept current by watches rather than polling.

kubectl-matching columns

Lists use the API server table endpoint, so columns match kubectl get, including custom resource printer columns.

Live logs

Stream pod logs with container selection, timestamps, substring or regex filters, previous-container reading and merged workload logs.

Diff before apply

The YAML tab writes back as a full replace, shows a diff first and refuses to overwrite an…

Safeguards per context

Mark a cluster read-only or protected, so writes are refused or need the context name typed to confirm.…

Pros

Free and Apache-2.0: No price, source on GitHub, and the maker says it will stay free.
Runs on three platforms: macOS, Linux and Windows builds, with Homebrew and auto-update from v0.1.5.
Signed releases: macOS builds are signed and notarised, and Linux packages are GPG-signed.
Open about gaps: Release notes and README state what is missing, including unsigned Windows installers.

Cons

Very new: First release August 1, 2026, version 0.1.7, and about 10 GitHub stars.
Windows not signed: The vendor says SmartScreen will warn on first run.
Solo maintainer: GitHub shows one main contributor, so support depends on one person.
No plugins or AI: I found no plugin system or built-in AI assistant listed.

CtrlOps

Manage Linux servers from a local desktop app with AI-assisted terminal commands

3.5

AppsInsight Score

Overview

What is CtrlOps?

Manage Linux servers from a local desktop app with AI-assisted terminal commands What is CtrlOps?

Editorial

Why we recommend it

CtrlOps solves an ordinary but costly problem: the operator who has too many server tabs and no clear view of which one is production. Named hosts, a visual file manager and live resource views make that workflow easier to understand. The AI terminal is most useful as a guided helper, with the actual command visible before execution.The flat per-user plans and unlimited server allowance are easy to evaluate, and the one-month trial gives teams time to test real tasks. I would check SSH reliability, deployment rollback, backup restore and model-provider handling before putting it into production operations. Local credential storage is a vendor claim, not an independent security assurance. This is a desk-research opinion.

Audience

Best for

Developers managing Linux VPS servers
Small teams with several client servers
Operators wanting a desktop SSH and SFTP workspace

Capabilities

Key features

Named server fleet

Organize unlimited SSH-connected Linux servers and work in separate tabs.

Approval-gated AI terminal

Describe a task, inspect the suggested shell command and approve execution.

Visual remote files

Upload, download, edit, create folders and adjust permissions without a separate SFTP client.

Resource monitoring

Inspect live CPU, RAM, disk and process information from server views.

Security audits

Run 25 predefined SSH security checks with a score, PDF report and reviewable fixes.

Pros

One-month trial includes Pro features without a card or automatic end-of-trial charge.
Unlimited servers are included across plans.
The documentation exposes concrete workflows rather than only broad AI claims.

Cons

Desktop/local-first design may not fit teams needing a hosted shared control plane.
AI model processing and production reliability were not independently tested.
Server changes still require Linux knowledge and production change control.

Vitals

Mac system monitoring by app, with 30-day history and menu-bar readouts

Overview

What is Vitals?

Mac system monitoring by app, with 30-day history and menu-bar readouts What is Vitals?

Editorial

Why we recommend it

Vitals has a clear purpose: show which app is behind a resource spike without making you add up helper processes. The combination of app-level history and a menu-bar view looks useful for people who notice slowdowns after the fact. Project folders, ports and container views also give developers a more relevant starting point than a flat process list.I would check macOS compatibility first, then evaluate whether the app grouping and history answer real questions on your own Mac within the 14-day refund period. There is no free trial. Sensor detail varies by hardware, and specialist process analysis still calls for other tools. This opinion is based on public documentation, not an installed test.

Audience

Best for

Mac users investigating recurring slowdowns
Developers tracking dev servers and containers
People wanting app-level history and menu-bar monitoring

Capabilities

Key features

App-level resource grouping

Combine helper processes under their parent app for CPU, memory, energy, disk and network readings.

30-day local history

Review app and system resource trends over recent hours, days and a month.

Alerts for resource-heavy apps

Flag sustained CPU use, growing memory and heavy disk or network activity.

Project and container views

Group development processes by folder, inspect ports and Docker containers, and find idle servers.

Custom menu-bar readouts

Arrange values, graphs and dropdown sections to match the metrics you use.

Pros

One-time licensing includes future updates.
App grouping and developer project views address different diagnostic needs.
Usage history remains local according to the privacy policy.

Cons

Requires macOS 15 or later and has no Windows or Linux version.
No free trial; testing the installed app requires purchase.
Some specialist Activity Monitor tools are not replicated, and hardware readings can be approximate.
