20 free diagnostic tools across five technical clusters — covering WordPress, self-hosting, networking, local AI, and visibility. Use the search or filter below to find what you need.
Identifies structural and content patterns that commonly appear on sites affected by Google quality updates — so you know what to investigate before starting a recovery project.
Analyses your WordPress site's front-end output to estimate plugin overhead, script weight, and stack sprawl — so you know which areas to review before performance or security work begins.
Traces redirect chains for a given URL and returns the full hop sequence, chain depth, and any inefficiencies — so you know which redirects are causing crawl or performance problems.
Reviews the visible trust, experience, and authority signals on your site that Google uses as quality indicators — showing you what is present, what is missing, and what to fix first.
Assesses whether your site's content is focused on a coherent set of topics or has drifted across too many loosely related themes — a common cause of declining authority in search.
Builds a practical self-hosted replacement plan for the cloud services you currently pay for, and shows the hardware and cost logic behind switching — so you can make an informed decision before buying anything.
Evaluates whether a NAS device can realistically handle your intended workloads — media serving, Docker containers, backups, or VM-style tasks — based on hardware class and typical performance limits.
Generates a structured Docker Compose starting point for your chosen self-hosted applications, including networking layout, volume configuration, and reverse proxy recommendations.
Helps you design a realistic Proxmox cluster before purchasing hardware — covering node count, CPU and RAM allocation, storage strategy, and VM versus container placement for your intended workloads.
Calculates your homelab's estimated monthly and yearly electricity cost based on hardware wattage, usage patterns, and your local electricity rate — so running cost is part of the decision before you buy.
Audits the full email deliverability stack for a domain — SPF, DKIM, DMARC, MX configuration, and common routing weaknesses — and returns a plain-language summary of what is working and what needs to be fixed.
Uses publicly visible signals to identify Cloudflare configuration patterns that often look correct on the surface but silently weaken security, performance, or SSL handling.
Creates a practical VLAN layout for your home or small office network — separating trusted devices, guest access, IoT hardware, and lab equipment into distinct segments with appropriate firewall boundaries.
Diagnoses why WordPress-originated email is failing or landing in spam by walking through the most common SMTP configuration, plugin, and routing problems — so you know exactly where to look and what to change.
Evaluates whether your current hardware can run a useful local AI model — covering VRAM, RAM, CPU requirements, and model size fit — so you know what is realistic before spending time or money on setup.
Designs a complete self-hosted AI stack based on your intended use cases — covering model selection, runtime environment, user interface, storage, and access control — so you have a coherent plan, not just a model name.
Compares the true long-term cost of renting a VPS against purchasing and running your own server — factoring in hardware cost, electricity, maintenance, and the operational tradeoffs between the two approaches.
Assesses how well your site is structured to appear in AI-generated search overviews and other emerging discovery surfaces — covering answerability, entity clarity, and machine-readable content signals.
Reviews the structured data on your pages against expected completeness standards — identifying missing fields, weak implementations, and opportunities to improve machine-readable interpretation of your content.
Generates a multi-factor content health score for your site — covering content depth, duplication risk, internal linking coverage, and structural quality signals — so you have a clear view of where the biggest problems are.
