StelaSpace

An HTML-first knowledge base for AI-generated artifacts · v1.0 · Owner: Founding team

Status: Live

1. Overview

AI agents now produce a flood of HTML artifacts — dashboards, reports, PRDs, plans — but there's no good home for them. They get trapped in chat sessions, zip files, and Slack threads.

StelaSpace gives every AI-generated HTML artifact a permanent, access-controlled URL. Drop a file in, or let a coding agent publish it over MCP. Either way you get a sandboxed, versioned, shareable link your team can rely on.

2. Problem

Interactive HTML doesn't survive markdown-based tools — charts and dashboards get flattened.
Sharing a raw .html file is awkward and insecure; recipients have to download and trust it.
There's no versioning, access control, or single place a team can browse what's been produced.

3. Target users

Builders (engineers)

Developers using Claude Code & Codex whose agents generate reports. They want zero-friction publishing straight from the editor.

Everyone else

Analysts, PMs, and operators who end up with an HTML file (from an AI chat, a notebook, or a BI export) and just want a clean shareable link.

4. Goals & non-goals

Goals

Publish an artifact to a permanent URL in seconds, by file or by agent.
Render interactive HTML exactly as generated, safely sandboxed.
Team access control, versioning, and search out of the box.

Non-goals

A document editor — StelaSpace hosts and shares; it doesn't author.
Markdown/Notion-style WYSIWYG. HTML is the first-class format.

Wedge: # of artifacts published via the MCP server (agent-native publishing).
Virality: signups attributable to a shared public artifact.
