About Antigravity SEO Kit
We didn't set out to build another SEO tool. We set out to make one that actually does the work.
The Story
From SaaS Frustration to Agentic Vision
In 2022, our founder Nguyên was managing SEO for over 50 client websites. The monthly bill? $400+ just for SaaS tools — Ahrefs for backlinks, Semrush for audits, Surfer for content. Five different dashboards, five different logins, five monthly invoices.
And after spending all that money, he still had to manually fix every issue himself.
The dashboards showed problems beautifully. Colorful charts, intimidating scores, urgent red alerts. But none of them wrote a single line of code. None of them generated a robots.txt. None of them injected Schema JSON-LD into a template.
That's when the question hit:
What if the tool didn't just show you what's broken — but fixed it?
The Backlink Years
Before Antigravity, there was Solann Digital — a backlink service and SEO consultancy that served 500+ domains across Vietnam. Through thousands of campaigns, we learned something that most SaaS companies never will: how SEO actually works in practice, not in theory.
We built internal tools — rank trackers, backlink managers, indexing checkers. Traditional SEO software. Useful, but conventional.
Then AI changed everything.
The Agentic Leap
When Google released Antigravity — their AI-native development platform — we saw the future clearly:
SEO doesn't need more dashboards. It needs agents.
An AI agent that crawls your site, identifies issues, builds a strategy, and writes the fixes directly into your source code. Not a tool you operate — a colleague that operates alongside you.
We spent months building 44 specialist AI skills — each one a narrow expert in a specific domain: technical SEO, content quality, schema markup, AI search optimization, entity analysis, and more. We connected them with 11 automated workflows that chain these skills into complete pipelines.
The result? The first Agentic SEO Platform — where one command does what five SaaS subscriptions and 40 hours of manual work used to accomplish.

That's it. That's the product.

Why We Built Antigravity SEO Kit
We believe in 4 principles:
1. SEO Should Be Autonomous
You shouldn't have to manually check 142 items on an audit checklist. An AI agent should crawl, analyze, score, and generate fixes — while you focus on building your business.
2. Your Data Should Stay Yours
Every competitor uploads your website data to their cloud. We process everything 100% locally on your machine. No upload. No login. No tracking. Your competitive intelligence never leaves your control.
3. SEO Tools Should Be Affordable
The $89-$449/month SaaS model is designed to extract revenue, not to democratize SEO. A one-time payment of $99 gives you the same analytical power for 3 years. That's a 97% saving over traditional tools.
4. The Future is Agentic + GEO
In 2026, 65-70% of searches are zero-click. Users ask ChatGPT and Perplexity instead of clicking Google results. Traditional SEO tools don't even measure this. Antigravity was built from day one with Generative Engine Optimization — optimizing websites for AI citation, not just Google ranking.
