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
Demo API keys shipped in the bundle
CriticalBolt 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.

Everything client-rendered — empty HTML served to crawlers
HighVite 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.

No sitemap.xml in /public
HighBolt 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.

No robots.txt (and no AI-crawler Allow rules)
HighCreate /public/robots.txt with four Allow blocks: GPTBot, ClaudeBot, PerplexityBot, Google-Extended. Without them, most AI engines default to doing nothing with your site.

No security headers at the edge
HighOn 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.

No llms.txt
MediumThe 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.
