Every JavaScript framework, fully indexable.
React, Angular, Vue, Svelte, Astro, Ember — UpRender ships the same clean HTML to every search engine, AI crawler, and social bot. No SSR rewrite. No framework lock-in.
One render layer, every framework.
Pick your stack. Each page covers the SEO problem in detail and how UpRender solves it in production.
JavaScript frameworks break crawlers in the same way.
Every modern JS framework ships an empty (or near-empty) HTML root and composes the UI at runtime. For humans on real browsers, that works fine. For the dozens of crawlers that don't execute JavaScript — Bingbot, GPTBot, OAI-SearchBot, ClaudeBot, Twitterbot, FacebookExternalHit, LinkedInBot, WhatsApp, Slackbot, Discordbot — it's an invisible page.
Search loses you
Googlebot's second-pass renderer is unreliable and slow. Bing, Yandex, and Baidu mostly don't render JS at all. Your routes index late, or never.
AI search skips you
GPTBot, OAI-SearchBot, ClaudeBot, and Claude-SearchBot fetch raw HTML and move on. If your content lives in JS, you're invisible in AI answers.
Social previews break
Twitter, LinkedIn, WhatsApp, and Slack crawlers don't run JS. Every share looks broken. Word-of-mouth dies quietly.
Engineering pays the bill
Adopting Next.js, Nuxt, Angular Universal, or SvelteKit SSR is a real migration. Most teams can't afford the cost in time, infra, or maintenance.
UpRender solves all of it at one layer. An edge worker detects bots, proxies them through our render engine, and returns clean HTML. Real users get your framework, untouched. The fix doesn't live in your codebase — and it doesn't break when you change frameworks.
How each framework handles SEO natively vs with UpRender.
Works with any stack.
UpRender is framework-agnostic by design. If a real browser can render it, UpRender can deliver it as HTML to every crawler.

Paste your URL. We'll fetch it as Googlebot, Bingbot, GPTBot, and the major social crawlers, and show you exactly what each one sees — side by side with what your users see.
Teams shipping with UpRender.
A brand built on details, ranking on details.
+312% image-search traffic and +98% Bing traffic after UpRender stabilized rendering on their React storefront. A market they'd written off, recovered.
CityHaus made every listing findable before it expired.
Perishable inventory, slow crawlers. CityHaus was leaving high-intent traffic on the table because new listings weren't being indexed inside their active window. UpRender rendered the React SPA and auto-injected Schema.org/RealEstateListing markup — no frontend changes — and 91% of listings now rank within 7 days of going live.
White-labeled rendering, in every audit.
A digital agency was losing engagements when SEO wins took too long. Bundling UpRender into client setup pushed retention from 70% to 95%.
Common questions about dynamic rendering.
Often yes. SSR handles initial render, but bot-heavy traffic from AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, Claude-SearchBot) can drive up your Nitro / Node server costs. UpRender absorbs bot traffic at the edge so your SSR layer only renders for human visitors — cutting infra spend on aggressive AI crawlers.
No. Real users never touch UpRender. They get your React app, your hydration, your interactivity — exactly as you built it. Only requests with bot user-agents get routed through our render path.
Both work. UpRender renders whatever your app actually produces in a real browser — Server Components, client components, async boundaries, streaming — and snapshots the final DOM.
Yes. We support hash-based routing via a rewriteHashbang: true option. AngularJS apps that haven't been touched in years become indexable without a rewrite.
Captured into the snapshot. Open Graph and Twitter Card tags injected by Helmet appear in the HTML served to social crawlers — so link previews work on LinkedIn, Twitter, WhatsApp, Slack, Discord, and Pinterest.
GPTBot, OAI-SearchBot, ClaudeBot, Claude-SearchBot, Google-Extended, Applebot-Extended, Meta-ExternalAgent, and every major social crawler. The list updates automatically as new bots emerge.
Yes. If a real browser can render it, UpRender can deliver it as HTML. Backbone, Marionette, Knockout, custom in-house SPAs — all indexable without a line of refactoring.
Fully supported. UpRender waits for streaming to complete and async boundaries to resolve before snapshotting.
