find-web-developer
Use whenever the user wants to find, shortlist, vet, or enrich US web development firms — building, refreshing, or rebuilding marketing sites, landing pages, ecommerce, WordPress/Webflow/Shopify, headless CMS, microsites, and web frontend work. Triggers on "find a web developer for a marketing landing page", "shortlist three Webflow agencies in California", "rebuild our ecommerce site on Shopify", or "pull contact info for these 8 web dev shop domains", even when described indirectly (redesign and rebuild our site, ship a microsite). Drives the ServiceGraph API (api.servicegraph.co) — a 100k+ US firm catalog filterable by industry, services, location, size, ratings. Defer to find-software-developer for custom backend/API/mobile/internal-tool work — anything beyond a website. Defer to find-marketing-agency when scope spans broader marketing beyond the build. Skip in-house web-engineer hires, "how do I build X" DIY questions, hosting/CMS-product comparisons, non-US firms, individual freelancers.
Why this skill is useful
Integrates with the ServiceGraph API to access a specialized dataset of US web development firms, which the AI wouldn't reliably generate on its own.
What it needs
Requires curl installed locally. Requires servicegraph account access. About 7k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
find-web-developer Overview Drive the ServiceGraph API (https://api.servicegraph.co) to find, shortlist, and enrich US web development firms via the proservices dataset. The catalog tags ~14k firms with serviceprovided:web-development under industry:itservices (web-development is the second-largest service tag in the catalog). Always pin both industry:itservices and serviceprovided:web-development. Platforms (WordPress, Webflow, Shopify, Next.js, etc.) and verticals (B2B, ecommerce, agency-vs-studio) are NOT separate tags — they're keyword substring matches on firm text. Any HTTP client works (curl, fetch, requests). Examples below use curl. Sibling skills — defer when scope is different Custom backend / API / internal tools / mobile app / distributed systems → find-software-developer. The end-product is software beyond a standard website. Broader marketing strategy and execution beyond the site build (paid media, content strategy, full digital agency engagement) → find-marketing-agency. SEO-only work on an existing site → find-seo-agency. Web devs build sites; SEO agencies optimize them. If the user wants new pages built AND optimized, this skill is fine. If unsure, this skill is correct for "build / rebuild / refresh a website" tasks. The deferral kicks in when the deliverable is non-website software or non-build marketing work. Prerequisites ServiceGraph access, either: the ServiceGraph MCP server (https://mcp.servicegraph.co) loaded in your harness — this plugin's .mcp.json wires it up; OAuth 2.1 + PKCE keeps credentials in the harness sandbox — or a ServiceGraph API key (vk…, minted at <https://servicegraph.co/profile/api-keys>) available as SERVICEGRAPHAPIKEY in the environment or .env.local for the REST path (setup steps under Auth below). An HTTP client for the REST path — the examples use curl. Instructions The loop is free-first: discovery, validation, search, and brief reads cost nothing; only unlock after the user confirms the spend. 1. …
