Updated 2026-10-04. Ranked by what the platform lets you actually do: serve root paths, inject structured data, install plugins, and connect endpoints. Scores backed by our 25-site audit.
Full control. Our free plugin handles everything in one click. 43% of the web runs on it.
Can serve agent.json, llms.txt, JSON-LD, and custom endpoints. Plugin repo for distribution.
Full control if you can edit code. Drop in three files and you're done.
No platform limits. Just upload agent.json, llms.txt, and add JSON-LD.
Edge layer that fixes any platform. 100 lines of open-source code.
Intercepts 3 paths, passes everything else through. Works in front of Wix, Squarespace, anything on Cloudflare DNS.
Good for products, limited for services. App ecosystem helps.
Can do JSON-LD and some structured data. Root paths restricted. WebMCP for checkout is a bright spot.
No root path control. Velo code can't serve agent.json where agents look.
JSON-LD via code injection works. Full readiness needs the Cloudflare edge layer.
Code injection only. No server-side control.
Same as Wix: JSON-LD yes, root paths no. Edge worker required for full score.
Scored 0/100 in our audit. Owner has zero self-serve path.
The Vanderbilt Barber on Square scored literally zero. No files, no markup, no control. Edge layer is the only fix.
