ToolsOps

About ToolsOps

ToolsOps gathers small digital utilities (calculators, converters, generators) for developers, sysadmins and technical teams. Each tool runs in your browser whenever possible and never sends your data to a server.

Why ToolsOps exists

Most technical utilities on the web demand an account, throw an intrusive consent modal at you, or quietly ship your input to an opaque backend. For a sysadmin pasting an SSH key, or a developer validating a JSON containing secrets, that contract is unacceptable.

ToolsOps was built as a concrete answer: utilities focused on what a modern browser actually knows how to do - parse, compute, convert, generate - with no backend in the middle. Whatever you type into a calculator is processed in your browser and not sent to a ToolsOps server.

This is not a vague promise; it is an architectural decision. There are no endpoints that receive payloads, no telemetry that includes content. If a tool cannot operate entirely on the client, we do not ship it.

Principles

  • Performance first

    Pre-rendered static pages, minimal JavaScript and audited dependencies. No eternal loading screens: the tools must work instantly on a modest laptop and on mobile with patchy connectivity.

  • Privacy by default

    No behavioral tracking, no browser fingerprinting and no hidden pixels. Analytics uses Cloudflare Web Analytics for aggregated metrics, does not receive the inputs you enter into the tools and is not used to personalize advertising. The cookie policy says exactly what happens and nothing more. When contextual advertising or AdSense eventually arrives - always behind a consent system - it will be documented just as plainly.

  • Real accessibility

    Keyboard navigable, contrast verified in light and dark themes, ARIA labels where they add value rather than where they decorate. Forms scale on mobile without horizontal overflow and results stay readable at 390 px.

  • Open architecture

    Each tool is an independent module with pure tested logic, separated UI and explicit configuration. Adding a new utility does not require modifying the existing ones or rewriting the rest of the site.

How we build

  • Client-side by default

    The rule is "if it can live in the browser, it lives in the browser". Cron, chmod, CIDR, YAML/JSON conversion - everything is computed locally. The server only serves static HTML and assets.

  • No external runtime dependencies

    We do not load third-party scripts and we do not call remote APIs with your input. The only network requests are the ones your own browser makes to download the page.

  • Strict internationalization

    Spanish and English keep strict parity. Every visible string lives in a typed dictionary; adding a new key forces the compiler to require its translation in both languages before the build will pass.

  • Verified technical accuracy

    Pure logic (parsing cron, validating JSON, computing subnets, interpreting chmod) has extensive unit tests. When a tool produces a result, that result is checked against documented edge cases.

Frequently asked questions

Does ToolsOps store my data?
No. The tools run entirely in your browser and do not send your input to any server. Some pages use the query string to share state via URL (the chmod calculator, for example) but only if you explicitly trigger it with the "copy link" button.
Are the tools free?
Yes. There are no accounts, subscriptions or paywalls. The sustainability plan includes non-intrusive contextual advertising in the future, but only once a consent system compliant with European regulation is in place.
Can I use it at work?
The tools are designed precisely for professional use: DevOps, engineering and sysadmin teams. Because nothing is sent to a server, they are compatible with environments where you cannot paste data into external services. Even so, check your organization's policy if you handle particularly sensitive information.
How are new tools prioritized?
By real utility, search demand and compatibility with the client-only rule. We aim to cover frequent areas (Linux permissions, networking, format conversion, cron expressions) before adding niche variants. If you have a suggestion, write to the contact email.
