# Lifub > Web tools for people who run a small site: a free Site Audit that grades technical SEO, security headers and page health; managed site search; cookieless analytics that tells humans from bots and AI agents; an IP intelligence API; and installable browser apps. Written in Rust, run from one server, with no third-party trackers. Every product page states its own price and free tier, and the apps below need no account to try. The HTTP API is documented at https://www.lifub.com/oas and the live surface is reported at https://www.lifub.com/status. AI crawlers are welcome here: the machine-readable permissions live in https://www.lifub.com/robots.txt, which names each crawler explicitly. ## Products - [Site Audit](https://www.lifub.com/product/site-audit): Reports, shareable findings and guided fixes for technical SEO and website security, with free usage limits and voucher pricing. - [Site Search](https://www.lifub.com/product/page-finder): Managed site search for small-business websites; EUR 49 a month after a free 14-day evaluation, one domain, up to 2,000 pages. - [Analytics](https://www.lifub.com/product/analytics): Cookieless, low-footprint web analytics with bot and AI-agent recognition, independent of Google and Microsoft. - [IP Intelligence](https://www.lifub.com/product/ip-intelligence): GeoIP, ASN and signup-risk scoring over an API, EUR 49 a month. - [Notes](https://www.lifub.com/product/notes): End-to-end encrypted, installable notes and tasks.
