An Oseox alternative for SEO monitoring
Oseox is a solid SEO regression tool — and they say it themselves: their crawler doesn't execute JavaScript. On a Nuxt, Next, Vue or React stack, it sees the raw HTML, not what the browser actually renders. Seogard compares both, page by page, and alerts you when they diverge. It doesn't replace Oseox: it covers the blind spot.
Already using Oseox? Good.
We're not going to sell you a replacement for a tool that works. Oseox does things Seogard doesn't: rank tracking, keywords, backlinks. Keep it.
One question: does your monitoring execute JavaScript? Oseox's doesn't — it's stated plainly in their documentation. On a server-rendered site, the day SSR breaks on 200 pages while the browser keeps rendering the JavaScript, nobody notices. That's the exact scenario Oseox tells you to watch for.
Seogard watches it by comparing both renders continuously. Cost to check: 30 seconds, your URL, no credit card.
Nuxt, Next, Vue, React SSR: the precise risk
Friday, 5pm, the team ships a header redesign. In the browser, everything works. But server-side, rendering broke on 200 product pages — the metas vanished from the raw HTML. Google indexes empty pages. Nobody notices, because the browser executes the JavaScript and shows a correct page.
On these stacks, two versions of your page coexist: the raw HTML the server sends (what Google indexes first, what AI reads) and the DOM after JavaScript hydration (what you see in the browser). Monitoring that doesn't execute JavaScript can only see one side. Seogard measures the gap between both, on every page, on every crawl.

Oseox and Seogard: a complement, not a replacement
Keep Oseox for rank tracking, keywords and backlinks — it does them well. Add Seogard for the blind spot a no-JS crawl leaves open: SSR/CSR regressions, and visibility to AI engines (llms.txt, GPTBot / ClaudeBot crawlers). The two complement each other.
Frequently asked questions
Does Oseox execute JavaScript?
No. Their documentation states it explicitly: their crawler does not execute JavaScript. It reads the raw HTML the server returns — enough for most sites, but not enough to detect a gap between the server render and the browser render on a modern JS stack.
Does Seogard replace Oseox?
No, and that's not the goal. Seogard does no rank tracking, no keywords, no backlinks. It focuses on one angle Oseox doesn't cover: comparing raw HTML and the JavaScript render continuously.
How much does Seogard cost?
Cloud is 0.01 €/month/monitored page, with a 14-day trial, no credit card. The self-hosted version is free (source available, BSL 1.1 license).
