Show HN: Perfectclone – Yoink the source code of any website, not an AI clone

A developer released perfectclone, a Python 3.10+ command-line tool that mirrors a public website's own HTML, JavaScript, CSS, fonts and images via a Playwright browser crawl in about 15 seconds, producing a servable folder rather than an AI-regenerated lookalike. In the project's own compat.py comparison at 1440×900, perfectclone matched nine sites at 100% pixel accuracy with zero hydration errors — including huly.io, nextjs.org, astro.build, svelte.dev, vitepress.dev, docusaurus.io, wordpress.org/news, paulgraham.com and example.com — while framer.com scored 96% and webflow.com 93%, and every clone loaded with zero requests to trackers. The tool ships clone, serve, replace, rehost and strip-trackers commands, strips trackers by default, and is installable via pip or uvx.

Pull the real frontend of any public site in ~15 seconds. No AI, no tokens. perfectclone clones any website 1:1. It crawls the site with a real browser Playwright , downloads the site's own HTML, JavaScript, CSS, fonts and images, and gives you a folder you can serve, edit and deploy. Then it lets you rebrand it, rehost it and strip the original owner's trackers without breaking it, including Next.js sites that hydrate on load. pip install perfectclone perfectclone clone example.com perfectclone serve example.com → http://localhost:8000 That's it. Chromium is downloaded automatically the first time you clone. Requires Python 3.10+. Or try it without installing anything, using uv https://docs.astral.sh/uv/ : uvx perfectclone clone example.com Most "clone any website" tools today regenerate the site: an AI agent looks at screenshots or scraped markup, writes a new React/Next.js app, and compares the result against the original with a visual-similarity score until it's close enough. That gets you a lookalike. The code is new, the behaviour is approximate, and there are always gaps. perfectclone doesn't regenerate anything. It mirrors the bytes the site actually serves, so the clone is the site: same markup, same bundles, same animations, same JavaScript running. Sometimes the real solution is the simple one. | | AI cloners | wget / HTTrack | perfectclone | |---|---|---|---| | Copies the site's real files | ❌ | ✅ | ✅ | | Pixel-identical on modern JS sites | ❌ | ❌ | ✅ | | Catches lazy-loaded JS, fonts, images | — | ❌ | ✅ | | React / Next.js sites still run | — | ❌ | ✅ | | Rebrand without breaking the site | ✅ | | ✅ | | Strips the original site's trackers | — | ❌ | ✅ | | Works without an LLM or API key | ❌ | ✅ | ✅ | Each card is one site split down the middle: the live site on the left, the clone on the right. scripts/compat.py clones each site, serves the copy, and compares its home page with the live one at 1440×900, with animations and videos paused on the same frame: | Site | Built with | Pixel match | Hydration errors | Notes | |---|---|---|---|---| | huly.io | Next.js | 100% | 0 | | | nextjs.org | Next.js | 100% | 0 | | | astro.build | Astro | 100% | 0 | | | svelte.dev | SvelteKit | 100% | 0 | | | vitepress.dev | VitePress Vue | 100% | 0 | | | docusaurus.io | Docusaurus React | 100% | 0 | | | wordpress.org/news | WordPress | 100% | 0 | | | paulgraham.com | Hand-written HTML | 100% | 0 | | | example.com | Static HTML | 100% | 0 | | | framer.com | Framer | 96% | 0 | Cookie banner needs Framer's backend | | webflow.com | Webflow | 93% | 0 | Cookie banner won't run on localhost; carousel caught mid-scroll | Every clone loaded with zero requests to trackers. Run it yourself with python scripts/compat.py , and please open an issue for any site that doesn't come out right. perfectclone clone <url -o out --max-pages 200 --extract --keep-trackers --ignore-robots perfectclone serve <site -p 8000 perfectclone replace <site <old <new --exact-case --substring perfectclone rehost <site <old-origin <new-origin perfectclone strip-trackers <site - clone writes out/site/ the working copy and out/manifest.json pages, failures, third-party hosts the site uses . --extract also saves each page's text, metadata headings, links, images, forms, JSON-LD and a full-page screenshot to out/extract/ . Trackers are stripped by default. - replace renames text everywhere: HTML, JS, CSS, JSON, SVG. It also handles the UPPER, lower and Capitalized variants, and leaves URLs and asset paths alone so nothing 404s. - rehost points canonical, Open Graph, JSON-LD and sitemap URLs at your domain. - serve works like a static host: clean URLs /about → /about/index.html , and / next/image requests are served from the mirrored originals. Rebrand a clone and put it online: perfectclone clone acme.com -o acme perfectclone replace acme "Acme" "Globex" perfectclone rehost acme https://acme.com https://globex.com npx netlify-cli deploy --dir acme/site --prod or any static host 1. Crawl with a real browser. Each page is rendered in Chromium and scrolled to the bottom, and every response is recorded. That catches what static mirrors miss: code-split JS chunks, fonts requested from CSS, images behind lazy loading. Links are followed breadth-first, seeded from the sitemap. robots.txt is respected unless you pass --ignore-robots . 2. Mirror the server's bytes. Pages are saved as the HTML the server sends, not the rendered DOM, because that's what the site's JavaScript expects to hydrate. Assets keep their URL paths, and CSS/JS are scanned for further references url , srcset , chunk paths until nothing new turns up. 3. Edit without breaking hydration. A Next.js App Router page ships its HTML and a serialized copy of the React tree in self. next f.push ... script chunks. Change one and not the other, and React throws a hydration error and re-renders from the payload, undoing your edit. perfectclone decodes the payload stream, edits it row by row, recomputes the UTF-8 byte lengths of length-prefixed text rows <id :T<hex ,… , rejoins rows that span chunks, and writes it back next to the matching HTML edit. 4. Strip trackers. Google Analytics/Tag Manager, the Meta pixel, LinkedIn Insight, Hotjar, Clarity, Segment, PostHog, HubSpot, TikTok, Reddit, X, Cloudflare Web Analytics, RB2B and more. They're removed from <script / <noscript tags, from preload hints, and from Next.js next/script elements that only exist in the payload. - No backend. Forms, logins, search and API calls still go to the original servers or fail . perfectclone copies the front end. - Next.js client-side navigation needs each page's RSC payload answered for ? rsc= requests. perfectclone mirrors them and perfectclone serve routes them. On a plain static host, internal links fall back to full page loads: everything still works, just without the instant transitions. - Chunks that are only requested after a click say, a modal's code are captured if the crawl triggered them or a bundle names them as a string. A bundle can also assemble a chunk URL at runtime, and that one may be missed. - Bot protection CAPTCHAs, aggressive Cloudflare rules can block the crawl. perfectclone does not try to get around it. - Embeds YouTube, Cal.com, maps and third-party CDNs keep loading from their own hosts. Clone apps behind a login, like dashboards. Today perfectclone sees what an anonymous visitor sees, and data that loads from APIs after the page renders isn't kept. The plan, for apps you have an account on: - Crawl as you. Sign in once in a browser window; perfectclone saves the session and crawls with it. - Record API responses. Keep every JSON response the app fetches during the crawl and have perfectclone serve replay them, so charts, tables and lists show real data offline. - Explore by clicking. Click through navigation, tabs and menus to reach views that only exist in client-side routing. The result is a clickable snapshot of the UI and its data at capture time. Saving, server-side filtering and live updates still need the real backend. Other ideas: hydration-aware editing for Nuxt, SvelteKit and Remix payloads, and a deploy helper that writes redirects / vercel.json rules so ? rsc= and / next/image work on static hosts.
