boltBoltSEO, Security & GEO audit for Bolt.new apps

Bolt.new runs your project inside the browser — which means the SEO story only begins after you deploy.

Point Pantra at your deployed Bolt URL (Netlify, Vercel, Cloudflare Pages) and we return the exact files to add: /public/sitemap.xml, /public/robots.txt, /public/llms.txt, _headers.

Why Bolt apps fail SEO out of the box

Bolt scaffolds React + Vite projects inside a WebContainer. The preview runs in your browser, not on a server, so every page is client-rendered and the deploy target (Netlify, Vercel, your own box) decides what server headers are possible. Out of the box Bolt ships no sitemap, no robots, no llms.txt, no security headers, and the bundle often contains the scaffolded-in demo secrets.

The 6 things every freshly deployed Bolt app fails on

  1. 1

    Demo API keys shipped in the bundle

    Critical

    Bolt starter templates sometimes bake a demo OpenAI / Supabase / Firebase key into the client so the preview works out of the box. Pantra grep-scans the deployed bundle and flags every key it recognises.

  2. 2

    Everything client-rendered — empty HTML served to crawlers

    High

    Vite ships a tiny index.html plus a JS bundle. AI crawlers do not execute JS. Pre-render the hero copy, headings, and meta tags directly into index.html so the initial response contains real content.

  3. 3

    No sitemap.xml in /public

    High

    Bolt does not auto-generate a sitemap. Drop one into /public and reference it from robots.txt. For static Vite builds, regenerate it on every deploy via a tiny build script.

  4. 4

    No robots.txt (and no AI-crawler Allow rules)

    High

    Create /public/robots.txt with four Allow blocks: GPTBot, ClaudeBot, PerplexityBot, Google-Extended. Without them, most AI engines default to doing nothing with your site.

  5. 5

    No security headers at the edge

    High

    On Netlify: add a _headers file. On Vercel: a vercel.json headers block. Pantra emits the exact snippet for your detected host, with CSP, HSTS, nosniff, X-Frame-Options and Referrer-Policy.

  6. 6

    No llms.txt

    Medium

    The llms.txt convention tells LLM-powered tools which pages to prioritise when summarising your site. It is a single markdown file in /public. Pantra generates the complete file tailored to your detected pages.

Frequently asked questions

Can I audit the Bolt preview URL?expand_more
The WebContainer preview is behind authentication and serves different JS than production. Deploy first (Netlify/Vercel/Cloudflare Pages — Bolt wires it up in two clicks), then audit the deployed URL.
How does Pantra detect Bolt?expand_more
The meta generator tag, the Vite bundle signature, and the presence of bolt.new / stackblitz.io origins in referrer or OG image URLs. Any two matching signals switch the prompts into Bolt flavor.
I deployed my Bolt app to Vercel — does Pantra use Cursor or Bolt prompts?expand_more
Bolt. The deploy target (Vercel) changes where headers go (vercel.json vs _headers), and Pantra adjusts — but the source edits happen in Bolt, so the prompts are Bolt-flavored.
Will fixing SSR force me to switch to Next.js?expand_more
No. You do not need real SSR — pre-rendering the key text into the static index.html is enough for AI crawlers and most SEO wins. A full SSR migration is optional.
