Agents thatpublishyour landing pages.

An agent builds the page, the validation gate checks it, and it goes live at your-slug.spfn.page. Every deploy is a versioned snapshot you can roll back.

Stay on the best agent

Your sites, versions and scopes live with Superself, not with the agent. When a new model wins at front-end work, switch — the site history comes along.

  • Slugs, versions and domains stay put — zero re-setup per agent
  • Works with Claude Code, Codex, Cursor and whatever ships next
  • Pilot a new agent on one page, then roll it out

Checked before live

Broken pages never meet your visitors

Static files only, 10 MB per bundle, every link hop and form post checked. Fail a rule and the page is not reachable.

Get started
Validation gate

Your rules check every deploy

External form posts, insecure password forms, meta refresh, mismatched anchors, brand impersonation — a pass goes live, a refusal stays offline, an unclear case waits for a human.

No hosting keys in the agent

Agents never hold your keys

The agent gets a scoped, device-approved credential that expires in 24 hours — never the S3 or DNS key. Revoke once and every deploy right it held stops working.
