Free SEO & launch tools for SaaS founders
Check your site, write better meta tags, add structured data, control crawlers and draft your launch copy. The same building blocks we use in BriefCraft, free to use.
Website SEO Checker & Latency Diagnostic
Fetches any public URL live and checks response time against Google's TTFB thresholds, HTTPS, indexability, title, description, canonical, headings, image alt text and a sample of internal links.
Meta Tag & Social Card Generator
Write your title and description with live length meters, preview them as a Google result and social cards, and copy the finished HTML.
Schema JSON-LD Generator
Fill in a form and get valid JSON-LD structured data for your SaaS product, company and FAQ, ready to paste and test in Google's Rich Results Test.
Robots.txt & AI Crawler Guard
Choose which search and AI crawlers may access your site, block private paths, and link your sitemap. Reputable crawlers follow robots.txt; it is a request, not a firewall.
Launch Copy Generator
Describe your product once and get a tagline, short and long directory descriptions, a Show HN post and a Product Hunt maker comment to edit.
Frequently asked questions
Are these tools free?
Yes. Every tool on this page works without an account or credit card. The live SEO checker and launch copy generator are rate-limited to a few runs every 10 minutes to keep them fast for everyone.
Can I use the generated tags, schema and robots.txt on client sites?
Yes. Everything the generators produce is yours to use on any site, commercial or personal.
Do the generators send my data anywhere?
The Meta Tag, Schema and Robots.txt generators run entirely in your browser. The SEO checker fetches the URL you enter from our server, and the launch copy generator sends your product description to our AI provider to draft the copy.
How often should I check my site?
Before every launch or major release, and after any migration or redesign. Renames during a release are the most common source of broken links and missing tags.
