Prerender Buddy and Hado SEO both serve rendered HTML for JavaScript-heavy websites. Both are relevant to AI-built and client-rendered sites. Their clearest difference is integration and product scope.
Hado SEO is DNS-first and includes additional domain and technical SEO controls. Prerender Buddy supports managed DNS and developer-controlled routing through middleware, Workers, edge functions, servers, or reverse proxies.
Quick answer
Choose PB when you want managed or developer-controlled rendering, or when AI answer evidence, website monitoring, full articles and reviewed publishing belong in the same workspace. Choose Hado SEO when its DNS-first deployment and domain controls fit the way you manage public pages.
PB Render is $19 per month; Hado Starter lists $19 per month. The meaningful difference is the included workload and controls, not an outdated PB launch discount.
Comparison table
| Decision point | Prerender Buddy | Hado SEO |
|---|---|---|
| Primary model | Rendering plus eligible AI evidence, full articles and reviewed publishing | DNS-first rendering with technical domain controls |
| Setup | Managed proxy or developer integration | DNS edge routing |
| Paid rendering entry | Render: $19/month, 3 websites, 25,000 fresh renders | Starter: $19/month |
| Usage unit | Fresh renders; cached hits do not consume fresh-render allowance | Domains, page inventory and bot page views |
| Additional workflow | AI answer evidence, page checks, full articles and configured reviewed publishing on Starter/Growth/Pro | Robots, sitemap, routing, recrawl and SEO analysis |
| Main reason to consider it | Integration choice and connected website and visibility work | DNS deployment and documented domain controls |

How the setup differs
Hado documents a DNS-level flow where the public hostname points through its edge service. The edge identifies bot traffic, returns cached rendered HTML to applicable bots, and forwards human visitors to the origin.
Prerender Buddy offers a similar managed path for hosts where the owner controls DNS but cannot run server-side code. It also offers developer paths where the existing request layer identifies relevant crawler traffic and requests rendered HTML. That can preserve the current DNS route and provide narrower route control.
A DNS setup is not inherently better or worse. It is useful when application code cannot intercept requests. It also places the service in the domain request path, so origin routing, HTTPS, redirects, cache behavior, and fallback behavior need to be understood.
Pricing and limits
Current Render is $19 per month for 3 websites and 25,000 fresh renders, with basic monitoring and no trial. Starter is $39 per month and adds AI visibility, full article drafts and reviewed publishing. Free includes 1 website and 500 fresh renders. Current PB plans
Hado's Starter documentation lists $19 per month for one domain, 300 pages and 150,000 monthly bot page views. Higher plans increase those allowances. Hado counts page inventory and bot visits, so its 150,000 views should not be compared directly with PB's 25,000 fresh renders. Hado pricing and definitions
List the site's public URLs, update frequency and crawler activity before estimating cost. A cache hit and a newly generated page are different events. Hado also documents a page-limit behavior in which new pages stop being prerendered until the inventory or plan changes. Check that behavior against a site that frequently adds routes.
Page limits versus render limits
Prerender Buddy’s model can fit a large URL inventory where only a subset of routes needs frequent fresh renders. The cost question is how often uncached or expired pages are generated.
Hado’s model can be easier to reason about for a small, stable sitemap. The cost question is whether the domain’s unique public page inventory and crawler page views remain inside the plan.
Neither unit is universally better. Use the site’s real sitemap, update frequency, and crawler logs to estimate usage.
Cache and refresh workflow
Hado documents manual recrawls and a purge/refresh API in beta. A queued render job is distinct from fresh HTML being available; verify the resulting response. Its dashboard documentation also describes sitemap sync. Public routes, removals and update dates should reflect the live site.
Prerender Buddy uses cache-aware rendering with plan-based freshness and per-site controls. The dashboard exposes crawler logs and response details so teams can distinguish a cache hit from a fresh render and investigate errors.
Avoid publishing a cache claim as a guarantee. Freshness still depends on configuration, origin availability, successful rendering, and correct invalidation.
Crawler coverage
Both products document major search, AI, and social crawler families. A crawler name on a product page should be interpreted precisely: user-agent recognition or routing does not prove authentic operator access, indexing, citation, or recommendation.
Use Prerender Buddy’s crawler-support page to distinguish detected, routed, tested, and independently verified status. Apply the same standard when evaluating any provider.
Choose from the deployment and ongoing work
Hado's DNS workflow can fit a team that wants its routing and technical domain controls together. PB can fit a team that wants managed setup or a developer request layer, with AI visibility, full article generation and reviewed publishing available in the same product. Article Generation explains the evidence/review path; integrations distinguish CMS drafts, approved publication, Git release and hosting rebuilds. Human management is optional, and Buddy does not autonomously publish.
Test an important content page, a redirect and a missing URL before routing production traffic. Then compare how each product helps you investigate a stale page or failed request. For the wider research workflow, see PB AI Visibility.
When an additional rendering layer may be unnecessary
If important public content is already present in the response delivered to the relevant crawlers, an additional renderer may not be needed. The same can be true when a planned rebuild will provide SSR or static generation.
That is a decision about rendering. You can still evaluate PB for AI visibility, website monitoring and full article/reviewed publishing workflows. Those capabilities do not require an existing rendering problem. See How PB Works.
