Edo91 SEO Toolkit vs Shazite: Which WordPress SEO Plugin Should You Choose?

Who This Comparison Is For

If you're choosing a WordPress SEO plugin outside the Yoast/AIOSEO/Rank Math mainstream, Edo91 SEO Toolkit and Shazite represent two very different bets on how SEO analysis should work. Both are new entrants distributed through the official WordPress.org repository, both are currently free to install, and both leave pricing an open question — but the similarities largely end there. One runs everything on your own server; the other ships your drafts to an external API. Understanding that architectural split matters more than any feature checkbox here.

Pricing Comparison

Neither plugin has a published pricing page, tiered structure, or in-plugin upgrade prompt as of this writing. Both are free to install because that's a requirement of WordPress.org distribution, not a guarantee of staying free forever. The difference is in the underlying cost structure that might eventually force a pricing decision: Edo91 runs its 11 tools locally on your own server, so there's no ongoing per-request cost on the vendor's side to recoup. Shazite, by contrast, sends every draft to an external Vercel-hosted API for scoring, which means the vendor is absorbing a server cost on every single analysis request — a pattern that has historically pushed similar API-backed WordPress plugins (grammar checkers, AI writing tools, image compressors) toward metered free tiers or paid plans once adoption grows. If pricing predictability matters for a client engagement, treat both as provisional, but treat Shazite's free status as somewhat more likely to change given its cost structure.

Feature Comparison

The two plugins aren't really scoped to do the same job. Edo91 SEO Toolkit is a broad, 11-tool suite covering site audits, schema markup generation, broken link checking, social preview cards, per-page on-page analysis, and exportable professional reports — essentially a technical and content SEO toolkit aimed at whole-site management. Shazite is narrower and deeper on one specific task: real-time content scoring inside the Gutenberg editor as you write, broken into keyword usage, readability, structural formatting, and internal linking, plus a Google-style SERP preview for titles and meta descriptions. Shazite explicitly does not do bulk site audits, sitemap generation, schema markup, or technical fixes like canonical tags and redirects. Edo91, conversely, doesn't offer a live in-editor scoring experience — its per-page analysis tool is closer to a one-off check than Shazite's continuous scoring as you type.

The architectural distinction is the biggest practical difference: Edo91's local execution means no site content ever leaves your WordPress install, which matters for compliance-sensitive niches like legal, healthcare, or finance clients. Shazite's API-based scoring means your unpublished drafts are transmitted to an external server before you get a score back — useful for offloading processing, but a real consideration for anyone with data-sensitivity concerns.

	Edo91 SEO Toolkit	Shazite
Price	Free (no pricing page published)	Free (no pricing page published)
Best for	Whole-site technical/content SEO, client reporting	Real-time content scoring while drafting in Gutenberg
Standout feature	11 tools including schema generation, broken link checks, and exportable professional reports	Live 0-100 score with SERP preview and structural/readability checklist
Data handling	Fully local, no third-party API calls	Sends draft content to an external Vercel-hosted API
Not built for	Competitive keyword research, backlink analysis, rank tracking	Bulk site audits, sitemap generation, schema markup, technical SEO

Which One Should You Choose?

Choose Edo91 SEO Toolkit if you want a broader technical SEO toolkit — site audits, schema markup, broken link scanning, social previews, and client-ready reports — especially if you're an agency or freelancer working with data-sensitive clients who'd flag an outbound API call in a security review. It's also the better fit for a solo blogger who wants several SEO utilities without a recurring subscription.

Choose Shazite if your priority is optimizing individual posts as you write them. The live scoring inside Gutenberg, the SERP snippet preview, and the specific checklist-style feedback (add more internal links, shorten a paragraph, work a keyword into an H2) make it well suited to solo bloggers polishing single posts, affiliate site owners worried about title/meta truncation, or content editors doing structural passes on existing copy.

If you need both, be aware there's currently no single plugin here that does it all: Edo91 skips live in-editor scoring, and Shazite skips technical/site-wide auditing entirely. Teams could reasonably run both side by side today, given neither charges anything yet — just keep in mind that pricing terms could shift for either, and Shazite's reliance on an external API is the one to watch most closely if data leaving your server is a dealbreaker.
