RoughEst Instant Estimate Calculator

RoughEst lets website visitors instantly calculate rough price range estimates for services without submitting a contact form. It reduces support friction, qualifies leads faster, and gives customers the confidence to move forward. Two calculator types are available: cost-per-square-foot (the customer enters two dimensions) and cost-per-run (the customer enters a single value). Each instance is independently configurable with its own multiplier, range percentages, labels, and disclaimer text. Multiple instances can run concurrently on the same site with completely different settings.

Mainframe: Headless WordPress Theme

Mainframe is a free, open source WordPress theme for developers who want WordPress as a headless CMS. It leaves the full wp-admin experience intact while adding enriched REST API fields on every response — featured_media_url, author_info, categories_info, ancestor_ids, and a one-call /wp-json/mainframe/v1/site endpoint for site name, description, and navigation menus. Configurable CORS, a deploy webhook compatible with Vercel, Netlify, and Cloudflare Pages, a custom login URL, and built-in auto-updates via GitHub Releases are included with no external dependencies.

Custom WordPress Plugin Development

Every WordPress site eventually outgrows off-the-shelf plugins. Custom plugin development produces purpose-built functionality with no bloat, no conflicting dependencies, and no subscription fees for features that should have been free to begin with. Plugins are delivered as stand-alone installable packages with full source code ownership transferred to the client.

  • Interactive calculators

    Instant pricing tools, ROI estimators, savings calculators, and configurators that give visitors answers without making them call or submit a form.

  • Visualization and design tools

    Product color simulators, layout preview tools, two-tone palette selectors, and other tools that help customers make decisions before they buy.

  • Lead qualification plugins

    Multi-step questionnaires that filter and segment leads before they reach the contact form, so every inquiry arrives with the information needed to respond usefully.

  • Custom admin functionality

    Custom post types, taxonomies, settings pages, meta boxes, and admin interfaces that extend WordPress without modifying theme files or installing a page builder.

  • Third-party API integrations

    Plugins that pull in live data from external services: CRMs, inventory systems, shipping APIs, weather feeds, or any REST API with a clear specification.

Custom WordPress Theme Development

Most WordPress themes are built for general audiences: they ship with dozens of layout options, demo content importers, and bundled page builders that the site will never use. A custom theme is built for one site. The markup is clean, the CSS is intentional, and the only code that ships is code that does something.

  • Headless WordPress themes

    WordPress as a CMS and REST API source, with a separate frontend consuming the data. The theme configures the API surface, manages credentials and CORS, and exposes the content your frontend framework needs. Mainframe is an open source example of this approach.

  • Block themes (Full Site Editing)

    Modern WordPress themes built with theme.json and block templates rather than PHP partials. Full Site Editing gives clients the ability to manage headers, footers, and layouts from the block editor without touching code, while the developer controls the design system.

  • Traditional PHP themes

    Custom-built themes with full control over markup and server-rendered output. No page builder, no bundled plugins, no framework overhead — just performant PHP templates with CSS built around the site’s actual design.

  • REST API extensions

    Themes that register additional REST fields, custom endpoints, and site summary routes to power decoupled frontends built with Next.js, Astro, SvelteKit, or any other JavaScript framework consuming the WP API.

  • Existing theme customization

    Child themes, targeted CSS and PHP overrides, and plugin conflict resolution for sites that need specific behavior changes without a full rebuild.

Why Go Custom

  • No bloat

    General-purpose plugins and themes include code for every possible use case. A custom build ships only what the site actually needs, which keeps load times down, reduces attack surface, and makes the codebase maintainable.

  • Full ownership

    Source code is delivered and owned outright by the client. No vendor lock-in, no license fees, no subscription renewals for features that should have been included at purchase. If the developer goes away, the code stays.

  • Exact behavior

    Off-the-shelf solves the general case. Custom solves your specific case — the exact UX, business logic, admin workflow, and output format your site requires, without workarounds or hacks to coerce generic tools into shape.

  • Reliable maintenance

    When a third-party plugin or theme breaks on a WordPress update, you wait for the vendor. When custom code breaks, the fix is a direct conversation with the developer who wrote it.

  • No surprise deprecations

    Commercial themes and plugins are routinely abandoned, pivoted to SaaS, or acquired and paywalled. Custom code doesn’t get deprecated by a vendor decision.
