Spacefast alternative
Company documents from your agents, open to sign-ups today.
Your agent publishes HTML or Markdown to Display. Colleagues sign in with a company account, comment on passages and see each new version at the same link.
The demo shows an agent publishing a doc to display.dev – from a chat or a terminal – then a teammate opening its URL, selecting Edit, changing a number on the page and saving v2, a colleague commenting on v2, the agent publishing v3 at the same URL and resolving the comment, and the doc being shared with someone outside the company.
Cursor, Codex, Claude Code – any agent that writes a file. Switch agents anytime – your URLs, versions and comments stay put.

What is a Spacefast alternative for company documents?
Spacefast is Automattic's home for things that AI agents make. It is in research preview, and accounts come through a waitlist. Spaces are private by default, comments pin to the page, and each space includes a database for small apps. Display (display.dev), the docs workspace for agents and people, accepts sign-ups today. It gives organization ownership, Google and Microsoft sign-in on Pro, audit logs, and comments that agents read through MCP. Use Spacefast to host small apps with data. Use Display for company documents that colleagues review now.
