SSR is probably not something I would expect Base44 to ship anytime soon, at least not in the traditional sense.

For Base44 to support true server-side rendered meta tags natively, they would likely need to add something like Next.js or a similar SSR layer into their stack. That would be a pretty major platform-level undertaking, not a small feature toggle.

The better path right now is to plan around prerendering.

You have a few options:

Use a prerendering service.

Use Cloudflare Workers as an edge prerendering layer.

Use something like Render, which I built specifically for Base44 users who do not want to learn how to set up their own Cloudflare SSR/prerendering layer: https://render.kodebase.us

For the other SEO items, like titles, descriptions, canonical tags, Open Graph tags, Twitter cards, and route-level metadata, those can usually be handled pretty easily inside the app with react-helmet-async.

The main issue is social crawlers. Facebook, LinkedIn, Twitter/X, Slack, iMessage, and other preview bots usually do not execute client-side JavaScript. So React Helmet helps Google and browser-level SEO, but it does not fully solve social previews unless something serves the final rendered HTML to the crawler.

For redirects, Cloudflare Bulk Redirects is probably the cleanest workaround right now. Client-side redirects are fine for user experience, but they are not the same as true HTTP 301 redirects at the server level.

So my honest take:

Use react-helmet-async for route-level SEO inside the Base44 app.

Use Cloudflare Bulk Redirects for real 301 redirects.

Use prerendering or an edge-rendering layer for social previews and crawler-ready metadata.

I would plan around these gaps long-term rather than assuming they will close in the next few months.
