Cactal
Most site builders assume a human clicking around; Cactal assumes an agent making API calls, which removes the awkward step where your coding assistant writes a site it cannot deploy. Versioned publishing with rollback is the feature that makes agent-driven edits survivable. Pricing is per site, so a portfolio of client sites adds up quickly.
Pros
- MCP server, API and SDK so agents can create, edit and publish without a browser
- Publishing is versioned with rollback, which matters when an agent makes the edit
- Output is real React code rather than a proprietary template format
- Managed hosting, storage, bandwidth, custom domains and analytics bundled
- Unlimited team members with per-site roles even on the paid tier
Cons
- $20 per site per month scales linearly — ten sites is $200
- No visual editor; the intended operator is an agent or a developer
- Company is young and no launch year or track record is published
